Chapter 6 - Property Classification Guidelines and Assessment Percentages

Classification

Property classification and assessment rates go hand-in-hand. Property is classified according to its use on January 1, the assessment date. The assessment rate and the approach to value (cost, market, or income) used to value a property are based upon the classification. All taxable property and exempt property that is used for religious, charitable, and private schools within each county is classified, valued, and listed on the assessment roll §§ 39-5-101 and 39-3-128, C.R.S. Property is categorized as either real or personal, taxable or exempt, and based on its use, is placed in at least one of the property classes. Once the use of a property is determined, the property is assigned to one or more of the various subclasses defined within this section. A class and subclass tree is provided in Addendum 6-A, Property Classes and Subclasses.

Property is classified according to its actual use on January 1. Evidence for determining actual use can include observations made during a field inspection, correspondence with the owner or other individuals, the legally permitted use, and the use for which improvements were constructed or later modified. If the actual use cannot be determined, the property should be classified according to its most probable use.

Except for residential improvements destroyed by natural causes as outlined in § 39-1-102(14.4)(b), C.R.S., and residential improvements demolished or relocated as outlined in § 39-1-102(14.4)(c), C.R.S., once any property is classified for property tax purposes, it remains classified as such until the actual use changes or the assessor discovers that the classification is erroneous. The assessor may request information from the property owner to determine the actual use in order to reclassify the property, but failure of the owner to supply such information shall not be the sole reason for reclassifying the property, § 39-1-103(5)(c), C.R.S. Refer to Property Changing Use in this chapter.

The actual value is multiplied by the appropriate assessment rate to arrive at the assessed value.

* There is no assessment rate applied to producing mines land. The actual and assessed values are the same figure, which is the greater of 25 percent of gross proceeds or 100 percent of net proceeds.

NOTE: Renewable energy personal property is assessed at 26.4% for tax year 2024. All other taxable personal property is assessed at 29% for tax year 2024. 

The most important distinction when classifying property is determining whether the property is real or personal. This distinction is important because different laws apply to these different types of property. The guidelines and definitions provided in this section can assist you in this process.

Real Property Classification

Real property classification may be determined by the following:

• Does a residential dwelling exist?

  If a residential dwelling exists, the land is classified as residential property unless the land use is agricultural. The land underlying an agricultural residence is classified according to the predominant agricultural land subclassification. However, as of January 1, 2012, up to two acres of land under a residential improvement that is not integral to an agricultural operation is classified as residential. Residential land and all residential improvements, including those located on agricultural land, are assessed at the appropriate residential assessment rate. The actual value must be determined by the market approach to value.

• Is the use other than residential?

  If so, the land and improvements are classified according to their use and assessed at the appropriate assessment rate. Actual value is determined through application and reconciliation of the cost, market, and income approaches to value.

• Do fixtures exist within the structure?

  Property may include fixtures. Fixtures are real property subject to assessment and are defined by statute, § 39-1-102(4), C.R.S.

  Definitions.

  (4) “Fixtures” means those articles which, although once movable chattels, have become an accessory to and a part of real property by having been physically incorporated therein or annexed or affixed thereto. “Fixtures” includes systems for the heating, air conditioning, ventilation, sanitation, lighting, and plumbing of such building. “Fixtures” does not include machinery, equipment, or other articles related to a commercial or industrial operation which are affixed to the real property for proper utilization of such articles. In addition, for property tax purposes only, “fixtures” does not include security devices and systems affixed to any residential improvements, including but not limited to security doors, security bars, and alarm systems.

  § 39-1-102, C.R.S.

  NOTE: Service station hydraulic lifts, gasoline pumps, and underground storage tanks fall under the fixture exception listed in § 39-1-102(4), C.R.S. Furthermore, these items do not fit the definition of real property contained in § 39-1-102(14), C.R.S. Consequently, according to § 39-1-102(11), C.R.S., these items must be classified and valued as personal property.

• Is the land used to produce agricultural products or for grazing livestock for the primary purpose of obtaining a monetary profit?

  If the land produces agricultural products or is grazed by livestock, it is classified as agricultural. The term “livestock” refers to domestic animals used for food for human or animal consumption, breeding, draft, or profit. The value of agricultural land is determined by considering the net earning or productive capacity of the land to the landlord over the past ten years. The net earning or productive capacity is capitalized at a rate of 13 percent, § 39-1-103(5)(a), C.R.S. The assessment rate for agricultural land and non-residential improvements is 26.4% for property tax years 2022 and 2023.

• Is the production of natural resource products occurring? If so, that portion must be separately classified.

  Refer to this section of this manual for more detail on natural resources subclasses. The procedures for the valuation and assessment of producing natural resources are generally specified by statute. Refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 6, Valuation of Natural Resources, Leaseholds and Lands, for a complete discussion.

Personal Property Classification

Personal property is virtually any property other than real property. Specific classification instructions are found in this section of the manual. Specific guidelines and procedures for valuing personal property are in ARL Volume 5, PERSONAL PROPERTY VALUATION MANUAL.

The residential land classification may remain in place for additional subsequent property tax years, not to exceed a total of five subsequent property tax years, if the assessor determines there is evidence the owner intends to rebuild or locate a residential improvement on the land. For purposes of this determination, the assessor may consider, but shall not be limited to considering, a building permit or other land development permit for the land, construction plans for such residential improvement, efforts by the owner to obtain financing for a residential improvement, or ongoing efforts to settle an insurance claim related to the destruction, demolition, or relocation of the residential improvement due to a natural cause.

(II) The residential land classification of the land described in subparagraph (I) of this paragraph (b) shall change according to current use if:

(A) A new residential improvement or part of a new residential improvement is not constructed or placed on the land in accordance with applicable land use regulations prior to the January 1 after the period described in subparagraph (I) of this paragraph (b), unless the property owner provides documentary evidence to the assessor that during such period a good-faith effort was made to construct or place a new or part of a new residential improvement on the land but that additional time is necessary;

(B) The assessor determines that the classification at the time of destruction, demolition, or relocation as a result of a natural cause was erroneous; or

(C) A change of use has occurred. For purposes of this sub-subparagraph
(C), a change of use shall not include the temporary loss of the residential use due to the destruction, demolition, or relocation as a result of a natural cause of the residential improvement.

(c)(I) Notwithstanding section 39-1-103 (5)(c) and except as provided in subsection (14.4)(c)(II) of this section, when residential improvements are destroyed, demolished, or relocated on or after January 1, 2018, that, were it not for their destruction, demolition, or relocation, would have qualified the land upon which the improvements were located as residential land for the following property tax year, the residential land classification shall remain in place for the year of destruction, demolition, or relocation and one subsequent property tax year if the assessor determines there is evidence that the owner intends to rebuild or locate a residential improvement on the land. For purposes of this determination, the assessor may consider, but is not limited to considering, a building permit or other land development permit for the land, construction plans for such residential improvement, or efforts by the owner to obtain financing for a residential improvement.

(II) The residential land classification of the land described in subsection
(14.4)(c)(I) of this section shall change according to current use if:

(A) A new residential improvement or part of a new residential improvement is not constructed or placed on the land in accordance with applicable land use regulations prior to the January 1 after the period described in subsection (14.4)(c)(I) of this section;

(B) The assessor determines that the classification of the land at the time of the destruction, demolition, or relocation was erroneous; or

Possessory Interest

For purposes of the procedures, the Division defines possessory interest as a private property interest in government-owned property that has been granted under lease, permit, license, concession, contract, or other agreement.

Generally, possessory interests constitute a right to the possession and use of government property for a period of time less than perpetuity. It represents a portion of the bundle of rights that would normally be included in a fee ownership; and its value, therefore, is typically something less than the value in perpetuity of the whole bundle of rights.

See ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 7, Special Issues in Valuation, for details on possessory interest.

Special Classification Topics

Property Changing Use

The assessor is prohibited by § 39-1-103(5)(c), C.R.S., from changing a property’s classification unless the actual use changes or the assessor discovers the classification is erroneous.

Actual value determined when.

(5)(c) Except as provided in sections 39-1-102(14.4)(b) or 39-1-102 (14.4)(c) and in subsections (5)(e) and (5)(f) of this section, once any property is classified for property tax purposes, it shall remain so classified until such time as its actual use changes or the assessor discovers that the classification is erroneous. The property owner shall endeavor to comply with the reasonable requests of the assessor to supply information which cannot be ascertained independently but which is necessary to determine actual use and properly classify the property when the assessor has evidence that there has been a change in the use of the property. Failure to supply such information shall not be the sole reason for reclassifying the property. Any such request for such information shall be accompanied by a notice that states that failure on the part of the property owner to supply such information will not be used as the sole reason for reclassifying the property in question. Subject to the availability of funds under the assessor’s budget for such purpose, no later than May 1 of each year, the assessor shall inform each person whose property has been reclassified from agricultural land to any other classification of property of the reasons for such reclassification including, but not limited to, the basis for the determination that the actual use of the property has changed or that the classification of such property is erroneous.

§ 39-1-103, C.R.S.

The assessor has the burden to prove that a property’s classification has changed or that the current classification is erroneous.

Assessors may request information from the taxpayer regarding the property’s use, but failure by the taxpayer to provide this information shall not be the sole reason for changing the property’s classification. The taxpayer must be advised of this in writing when additional information regarding property use is requested that could affect the property’s classification.

When the use of a property changes after January 1, the assessment date, the classification assigned to the property as of January 1 remains in place until the following January 1. This includes a class or subclass change mid-year, such as a subdivision plat filed after January 1, a titled manufactured home that moves onto or is removed from a parcel, or a single-family residence converted to a retail store. For example:

• A residential subdivision plat is filed in June of the current year. The plat is processed by deleting the original unplatted vacant land parcel (0550) and creating new parcels for the platted residential lots. The new lots remain classified as unplatted vacant land (0550) for the remainder of the current year. The following January 1, the platted lots are reclassified as vacant residential lots (0100).
• A titled manufactured home moves from another Colorado county onto a vacant residential lot (0100) in April of the current year. The land remains classified as a vacant residential lot (0100) for the entire current year. On January 1 of the following year, the land is reclassified as residential manufactured home land (1135), and the titled manufactured home is classified as a manufactured home improvement (1235).
• A Certificate of Permanent Location, along with an application for purging a Certificate of Title is filed and recorded in June of the current year for a titled manufactured home located on land (1135/1235). The titled manufactured home and land remain classified as 1135/1235 for the current year. On January 1 of the following year, the land and the manufactured home are reclassified as single-family residential (1112/1212).
• A single-family residence (1112/1212) is converted to a retail store in February of the current year. The property remains classified as a single-family residence for the entire year and is reclassified the following January 1 as commercial merchandising property (2112/ 2212).

Exceptions to the rule include:

• Real property that changed taxable status after January 1.
• The classification of land when a structure is assessed as omitted property. (The omitted structure was in place on January 1; therefore, the use of the land must correspond.)
• Residential improvements that are destroyed by natural causes (i.e., fire, explosion, flood, tornado, action of the elements, act of war or terror, or similar cause beyond the owner’s control). In these cases, the residential land classification may remain in place for additional subsequent property tax years, if the assessor determines there is evidence the owner intends to rebuild or locate a residential improvement on the land, § 39-1-102(14.4)(b), C.R.S.
• Residential improvements that are destroyed or demolished on or after January 1, 2018, where the owner intends to rebuild or locate a residential improvement on the land. In these cases, the residential land classification may remain in place for the year of destruction, demolition, or relocation and one subsequent tax year if the assessor determines there is evidence the owner intends to rebuild or locate a residential improvement on the land, § 39-1-102(14.4)(c), C.R.S.

Partially Completed Structures

Section 3(1)(b) of article X of the Colorado Constitution requires that residential real property include a residential dwelling unit. The Colorado Court of Appeals addressed this requirement in Vail Assoc., Inc. v. BAA, 765 P.2d 593 (Colo. App. 1988). The court in that case affirmed the requirement that a “dwelling unit” be present for a property to be classified as residential. The court rejected the argument that residential platting, residential zoning, completed roads, natural gas lines, electricity lines, sanitary sewer lines, storms sewer lines, cable TV lines, telephone lines, water lines and ski ways were sufficient to meet the constitutional requirement for residential classification.

A completed structural foundation for a residential improvement must be in place on January 1 to meet the “dwelling unit” minimum requirement set out by the Constitution and the Court of Appeals for a property to be classified as residential. For manufactured homes, a support system such as tie-downs or footers must be in place on January 1 to meet the “dwelling unit” minimum requirement. Guidelines for valuation of partially completed structures are published in ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 1, Statutory and Case Law References.

Destroyed Property

Residential Property Destroyed Where the Owner Intends to Rebuild or Locate a Residential Improvement on the Land:

Where residential improvements are destroyed, demolished, or relocated after January 1, 2018, and the assessor determines there is evidence that the owner intends to rebuild or relocate a residential improvement on the land, the residential land classification shall remain in place for the year of destruction, demolition, or relocation and one subsequent property tax year. For purposes of this determination, the assessor may consider, but is not limited to considering, a building permit for the land, construction plans for such residential improvement, or efforts by the owner to obtain financing for a residential improvement, § 39-1-102(14.4)(c), C.R.S..

The value of an improvement that is destroyed or demolished after January 1 is prorated according to § 39-5-117, C.R.S. For further information on prorating the value of destroyed structures, refer to Chapter 4, Assessment Math, Prorating Values.

Fully Destroyed Structures:

Structures that were fully destroyed prior to January 1 of the current year are removed from the current assessment roll, and if no other structures exist on the parcel, the land is reclassified as vacant for the current assessment year, unless the destroyed structure was a residential improvement destroyed by natural causes as outlined below. Structures fully destroyed after January 1 are classified according to their use on January 1 of the current year, and the value is prorated according to § 39-5-117, C.R.S. For further information on prorating the value of destroyed structures, refer to Chapter 4, Assessment Math, Prorating Values.

Partially Destroyed Structures:

Structures that were partially destroyed prior to January 1 of the current year are classified for the current year according to their previous use. If no effort is made to repair the partially destroyed structure within a year, reclassify the property as vacant land, unless the partially destroyed structure is a residential improvement destroyed by natural causes as outlined below. The assessor, after physically inspecting the property and reviewing the facts, may make the determination to allow the improved classification to continue.

Property Destroyed by Natural Causes:

When residential improvements are destroyed due to a natural cause, e.g., fire, flood, tornado, etc., the residential land classification shall remain in place for the year of destruction and the two subsequent property tax years. If the assessor determines there is evidence the owner intends to rebuild or locate a residential improvement on the land, the residential land classification may remain in place for additional subsequent tax years, not to exceed a total of five subsequent property tax years, unless the property owner provides documentation to the assessor that a good-faith effort was made to construct a new residential improvement and that additional time is necessary, § 39-1-102(14.4)(b), C.R.S.

Similarly, when the productivity of a parcel of agricultural land is destroyed due to a natural cause, the agricultural classification shall remain in place for the year of destruction and up to four subsequent property tax years so long as the assessor receives evidence that the owner is in the process of rehabilitating the land for agricultural use, § 39-1-103(5)(e)(1), C.R.S. Refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 5, Valuation of Agricultural Land, for a complete discussion of agricultural classification.

Definitions.

(8.4) “Natural cause” means fire, explosion, flood, tornado, action of the elements, act of war or terror, or similar cause beyond the control of and not caused by the party holding title to the property destroyed.

§ 39-1-102, C.R.S.

Equities in State Land

According to the Colorado State Board of Land Commissioners (State Land Board), equities in state lands are no longer sold under contract and the last such sale occurred in 2014. The State Land Board’s current practice is to sell any such lands and to transfer fee simple title to such lands via patent. The state no longer finances these purchases. For further information, refer to Chapter 3, Specific Administrative Procedures.

Contiguous Parcels of Land With Residential Use

Beginning January 1, 2022, a parcel of land may receive the residential real property classification under certain circumstances. Residential land is defined in § 39-1-102(14.4)(a), C.R.S., as “a parcel of land upon which residential improvements are located.” The definition includes contiguous parcels under § 39-1-102(14.4)(a)(I)(C).

The definition has the following requirements:

1. The parcel of land must be contiguous with the residential parcel,
2. The parcel of land must have identical ownership based on record title, and
3. The parcel of land must contain a related improvement that is essential to the use of the residential improvement.

Section 39-1-102(14.4)(a)(III) defines:

1. Contiguous to mean parcels that physically touch; except that contiguity is not interrupted by an intervening local street, alley, or common element in a common-interest community, and
2. Related improvements to mean a driveway, parking space, or improvement other than a building, or that portion of a building designed for use predominantly as a place of residency by a person, a family, or families.

As with all classification decisions, a property inspection is recommended.

Growth Valuation for Assessment

Qualifying counties severely impacted by residential growth may opt to assess new construction that occurs between January 1 and July 1, § 39-5-132, C.R.S.

If the county commissioners make a finding of severe growth impact as provided in § 39-5-132, C.R.S., the assessor values new construction on both January 1 and July 1. The prorated value of the construction completed between January 1 and July 1 is added to the assessment roll.

The classification of the land is based on its status on the January 1 assessment date, unless the newly constructed building is a residential unit. If the newly constructed building is a residential unit and if the land was classified as vacant, the land is reclassified as residential and the assessment rate applied to the land is based on the residential classification, § 39-5-132(2)(c), C.R.S. ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 4, Valuation of Vacant Land Present Worth, provides procedures for present worth valuation. In the procedures, it directs that the present worth value is applied only to vacant land. Once a building is on the land, present worth valuation does not apply; thus, the Division suggests the present worth valuation be removed when the land classification is changed to residential due to the installation of a residential improvement.

Manufactured Home With a Non-Residential Use

Manufactured homes with a non-residential use are classified according to their use and the corresponding assessment rate is applied to the actual value. An example of this is a manufactured home used as a sales office.

Camper Trailers, Multipurpose Trailers, Trailer Coaches, and Camper Coach

Camper trailers, multipurpose trailers, and trailer coaches are categorized as Class D vehicles and are issued license plates by the clerk and recorder of the county in which the owner resides. Controversy over classification often occurs when these types of vehicles are parked in one place for an extended period of time. In contrast to titled manufactured homes, titles to these types of vehicles are not purged. The Division of Motor Vehicles considers them to be temporary living quarters rather than manufactured homes. The definitions of these vehicles are as follows:

Definitions.

(14) “Camper trailer” means a wheeled vehicle having an overall length of less than 26 feet, without motive power, which is designed to be drawn by a motor vehicle over the public highways and which is generally and commonly used for temporary living or sleeping accommodations.

§ 42-1-102, C.R.S.

Definitions.

(60.3.) “Multipurpose trailer” means a wheeled vehicle, without motive power, that is designed to be drawn by a motor vehicle over the public highways. A “multipurpose trailer” is generally and commonly used for temporary living or sleeping accommodation and transporting property wholly upon its own structure and is registered as a vehicle.

§ 42-1-102, C.R.S.

Definitions.

(106)(a) “Trailer coach” means a wheeled vehicle having an overall length, excluding towing gear and bumpers, of not less than twenty-six feet, without motive power, that is designed and generally and commonly used for occupancy by persons for residential purposes, in temporary locations, and that may occasionally be drawn over the public highways by a motor vehicle and is licensed as a vehicle.

§ 42-1-102, C.R.S.

 

Definitions.

§ 42-1-102, C.R.S.

Agricultural Type Buildings on Non-Agricultural Property

Like all property, the use of the structure must be determined.

1. If the structure is used as an integral part of a residence, it is classified as residential.
2. If the structure is used in conjunction with a commercial/industrial enterprise, it is classified accordingly.
3. If the structure is used in conjunction with a farm/ranch operation, it is classified as a farm/ranch support building.

Residential Properties That are Hotel Units

Units in condominium projects that are operated as hotels, including units held in time share estates or other partial ownership interests, are classified as residential property (1230) unless they meet the definition of a “hotel unit” as defined below. Residential units that qualify as “hotel units” are classified as commercial lodging (2115/2215) unless they meet the exceptions in §§ 39-1-102(5.5)(a)(II) and (III), C.R.S. (See statutory definitions below.)

Definitions.

(5.5)(a) “Hotels and motels” means improvements and the land associated with such improvements that are used by a business establishment primarily to provide lodging, camping, or personal care or health facilities to the general public and that are predominantly used on an overnight or weekly basis; except that “hotels and motels” does not include:

(I) A residential unit, except for a residential unit that is a hotel unit;

(II) A residential unit that would otherwise be classified as a hotel unit if the residential unit is held as inventory by a developer primarily for sale to customers in the ordinary course of the developer’s trade or business, is marketed for sale by the developer, and either has been held by the developer for less than two years since the certificate of occupancy for the residential unit has been issued or is not depreciated under the internal revenue code, as defined in section 39-22-103(5.3), while owned by the developer;

(III) A residential unit that would otherwise be classified as a hotel unit if the residential unit has been acquired by a lender or an owners’ association through foreclosure, a deed in lieu of foreclosure, or a similar transaction, is marketed for sale by the lender or owners’ association and is not depreciated under the internal revenue code, as defined in section 39-22-103(5.3), while owned by the lender or owners’ association.

(b) If any time share estate, time share use period, undivided interest, or other partial ownership interest in any hotel unit is owned by any non-hotel unit owner, then, unless a declaration or other express agreement binding on the non-hotel unit owners and the hotel unit owners provides otherwise:

(I) The hotel unit owners shall pay the taxes on the hotel unit not required to be paid by the non-hotel unit owners pursuant to subparagraph (II) of this paragraph (b).

(II) Each non-hotel unit owner shall pay that portion of the taxes on the hotel unit equal to the non-hotel unit owner’s ownership or usage percentage of the hotel unit multiplied by the property tax that would have been levied on the hotel unit if the actual value and valuation for assessment of the hotel unit had been determined as if the hotel unit was residential real property.

(III) For purposes of determining the amount due from any hotel unit owner or non-hotel unit owner pursuant to subparagraph (II) of this paragraph (b), the assessor shall, upon the request of any hotel unit owner or non-hotel unit owner, calculate the property tax that would have been levied on the hotel unit if the actual value and valuation for assessment of the hotel unit had been determined as if the hotel unit were residential real property. A hotel unit owner or non-hotel unit owner may petition the county board of equalization for review of the assessor’s calculation pursuant to the procedures set forth in section 39-10-114. Any appeal from the decision of the county board shall be governed by section 39-10-114.5.

(c) As used in this subsection (5.5):

(I) “Condominium unit” means a unit, as defined in section 38-33.3-103(30), C.R.S., and also includes a time share unit.

(II) “Hotel unit owners” means any person or member of a group of related persons whose ownership and use of a residential unit cause the residential unit to be classified as a hotel unit.

(III) “Hotel units” means more than four residential unit ownership equivalents in a project that are owned, in whole or in part, directly, or indirectly through one or more intermediate entities, by one person or by a group of related persons if the person or group of related persons uses the residential units or parts thereof in connection with a business establishment primarily to provide lodging, camping, or personal care or health facilities to the general public predominantly on an overnight or weekly basis. “Hotel unit” means any residential unit included in hotel units. For purposes of this subparagraph (III):

(A) “Control” means the power to direct the business or affairs of an entity through direct or indirect ownership of stock, partnership interests, membership interests, or other forms of beneficial interests.

(B) “Related persons” means individuals who are members of the same family, including only spouses and minor children, or persons who control, are controlled by, or are under common control with each other. Persons are not related persons solely because they engage a common agent to manage or rent their residential units, they are members of an owners’ association or similar group, they enter into a tenancy in common or a similar agreement with respect to undivided interests in a residential unit, or any combination of the foregoing.

(IV) “Project” means one or more improvements that contain residential units if the boundaries of the residential units are described in or determined by the same declaration, as defined in section 38-33.3-103(13), C.R.S.

(V) “Residential unit” means a condominium unit, a single family residence, or a townhome.

(VI) “Non-hotel unit owner” means any owner of a time share estate, time share use period, undivided interest, or other partial ownership interest in any hotel unit who is not a hotel unit owner with respect to the hotel unit.

(VII) “Residential unit ownership equivalent” means:

(A) In the case of time share units, time share interests or time share use periods in one or more time share units that in the aggregate entitle the owner of such time share interests or time share use periods to 365 days of use in any calendar year or 366 days of use in any calendar year that is a leap year; and

(B) In the case of residential units other than time share units, undivided interests or other ownership interests in one or more such residential units that total 100 percent. For purposes of this sub-subparagraph (B), any undivided interest or other ownership interest not stated in terms of a percentage of total ownership shall be converted to a percentage of total ownership based on the rights accorded to the holder of the undivided interest or other ownership interest.

(VIII) “Time share unit” means a condominium unit that is divided into time share estates as defined in section 38-33-110(5), C.R.S., or that is subject to a time share use as defined in section 12-10-501(4), C.R.S.

§ 39-1-102, C.R.S.

Example – Single unit ownership equivalent of non-time share units

John Q. Taxpayer owns:

NOTE: If the above unit ownership equivalent is part of a block of more than four unit ownership equivalents, but is not used as part of a lodging facility, the units are classified
as residential.

A residential unit that meets the definition of a “hotel unit” is still classified as residential if:

1. The residential unit is held as inventory primarily for sale and marketed by a developer to customers in the ordinary course of the developer’s business, and the unit has either been held by the developer for less than two years since the certificate of occupancy for the unit was issued or the unit has not been depreciated under the internal revenue code while owned by the developer, § 39-1-102(5.5)(a)(II).
2. The residential unit has been acquired by a lender or owners’ association through foreclosure, a deed in lieu of foreclosure, or a similar transaction, and the unit is marketed for sale by the lender or owners’ association, and the unit has not been depreciated under the internal revenue code, § 39-1-102(5.5)(a)(III), C.R.S.

For additional information, refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 7, Special Issues in Valuation.

Tax Apportionment for Hotel and Non-Hotel Owners

The ownership interests in a hotel unit may be split between hotel unit owners and non-hotel unit owners, §§ 39-1-102(5.5)(c)(II), (III), and (VI), C.R.S. When the two types of owners, hotel unit owners and non-hotel unit owners, hold ownership of a unit, the entire unit is classified and taxed as commercial lodging.

Unless an express agreement between the owners states otherwise, the non-hotel unit owner pays only the amount of tax that would be paid if the unit were classified as residential. The hotel unit owner pays the difference between the tax paid by the non-hotel unit owner and the total tax due, § 39-1-102(5.5)(b), C.R.S.

To assist the owners in determining the apportionment of the tax, at the request of any owner, the assessor calculates the tax that would have been levied if the unit had been classified as residential property, § 39-1-102(5.5)(b)(III), C.R.S. If any owner disagrees with the assessor’s calculation, a petition may be filed with the county for a review under the abatement statute, § 39-10-114, C.R.S. Any appeal of the decision is governed by § 39-10-114.5, C.R.S.

Example – Apportionment of tax

• The unit has an actual value of $500,000.
• A hotel unit owner owns a 50% interest in the unit.
• Two non-hotel unit owners own the remaining 50% interest, each with a 25% interest.
• The tax rate is 80 mills.

1. Calculation of total taxes due:

   $500,000 Actual value × 0.29 Assessment rate = $ 145,000 Assessed value
   $ 145,000 Assessed value × 0.080000 Tax rate = $11,600 Tax due to treasurer

2. Hypothetical calculation of total tax, had the property been classified residential:

   (The assessor must provide this upon request of the owner(s).)
   $500,000 Actual value × TBD Assessment rate = $TBD Assessed value
   $TBD Assessed value × 0.080000 Tax rate = $ TBD Tax

3. Apportionment of tax between owners:

   Non-hotel unit owner #1:
   $TBD Tax × 0.25 25% interest = $TBD Residential tax for owner #1

   Non-hotel unit owner #2:
   $TBD Tax × 0.25 25% interest = $TBD Residential tax for owner #2

   Hotel unit owner:
   $11,600 Total tax - $TBD Owner #1 tax - $TBD Owner #2 tax = $TBD Hotel unit owner tax

   Total tax due to the county treasurer: $ 11,600

Property Class and Subclass Descriptions

This section contains a description of each property class, as well as detailed criteria and classification codes for each property subclass.

Vacant Land

Vacant land is land that has no buildings or fixtures, other than minor structures or non-minor structures. Minor structures are improvements that do not add value to the land on which they are located and that are not suitable to be used for and are not used for any commercial, residential, or agricultural purpose, § 39-1-103(14)(c)(II)(A), C.R.S. See the Minor structures subclass code and description below. See the non-minor subclass code and description below.

Land or site improvements such as sewer, water, electricity, curb and gutter, and street paving may exist on vacant land. The land may be platted or unplatted. Vacant land includes all vacant lots, parcels, sites, or tracts whether platted or unplatted. Agricultural land, as defined by § 39-1-102(1.6)(a), C.R.S., and producing natural resource lands are excluded from this classification. Zoning and most probable future use are the classification criteria for platted vacant land. Unplatted parcels are classified by size.

Minor structures consist primarily of sheds and other minor improvements which are not used in conjunction with a residence, a commercial enterprise, or agricultural land. Minor structures do not add value to the land on which they are located, § 39-1-103(14)(c)(II)(A), C.R.S. Structures that have value should be classified using the appropriate subclass code based on use. Minor structures located on agricultural land are classified as farm/ranch support buildings.

Report the following information:

Non-Minor Structures Imp. Code: 0700

Non-minor structures are buildings that add value to what would otherwise be considered vacant land, but do not meet the statutory requirements to be classified as residential, commercial, industrial or agricultural.

Report the following information:
Improvement value

Residential Property

All residential dwellings, land, improvements, and taxable personal property that are used in conjunction with residential dwellings, as well as conforming common interest community property, are classified according to use into the subclasses of residential property. If two or more residential uses apply to a property, each use shall be assigned to the appropriate subclass. Agricultural residences are assessed at the prevailing residential rate. All of the residential subclasses are listed on the residential page of the Abstract of Assessment (abstract).

A subclass was not created for properties where the owner qualifies for the senior citizen or veteran with a disability exemptions. The assignment of such code would create a method of identifying such properties which would jeopardize the confidentiality of the exemption. The Division discourages the creation of an internal code by assessors for the senior citizen or veteran with a disability exemptions.

Residential Parcel Size

There is no prescribed parcel size that may be entitled to residential classification. Each situation must be reviewed individually. Two court cases are relevant in this situation. In Gyurman v. Weld County Board of Equalization, 851 P.2d 307 (Colo. App. 1993), the owner presented sufficient evidence to prove a 36.75-acre tract should be classified as residential. In Farny v. Dolores County Board of Equalization, 985 P.2d 106 (Colo. App. 1999), it was determined a 320-acre parcel should be classified as residential based on the owner’s use of the parcel in conjunction with the residential use of a cabin.

Mixed-Use Properties

When a portion of an improvement is used for residential purposes and a portion is also used for any other purpose, the actual value of each portion of the improvement is determined using the appropriate approaches to appraisal. The actual value of the land is determined by application of the appropriate approaches to appraisal. The land value is allocated to the appropriate classes based upon the proportion that the actual value of each of the classes to which the improvement is allocated bears to the total actual value of the improvement.

The appropriate assessment rate is then applied to each portion of the land and improvement, § 39-1-103(9)(a), C.R.S. In the case of land containing more than one improvement, one of which is a residential dwelling, the classification of the land is based on the predominant or primary use of the land in compliance with land use regulations. If multi-use is permitted by land use regulations, the land is allocated in the manner described in § 39-1-103(9)(b), C.R.S.

When there are no county land use regulations, the allocation of land to the primary and secondary uses is determined by the assessor based on his/her judgment. It is acceptable to determine the land allocation for the secondary use based on the square footage of the secondary use within the improvement and a reasonable area around the improvement. The classification of the remaining portion of the land is tied to the primary use. The appropriate assessment rate is then applied to each portion of the land.

An exception to this is land underlying an agricultural residence that is integral to an agricultural operation conducted on such land. In this case, the land classification is based on the predominant agricultural land class.

NOTE: Manufactured home hook-up values are included with and abstracted with the land. Detached garages and sheds used in conjunction with a manufactured home are classified as manufactured homes (1235).

*Manufacturers stopped producing mobile homes in 1976. This type of structure is now called a manufactured home. Manufactured homes are built to HUD standards and can be identified by a red plate usually located on the back of the structure. If the structure is shipped in more than one piece, each piece will have a red plate. If the red plate is missing, an 8 1/2 × 11 inch paper “data plate,” which gives the specifications of the structure, may be located near the water heater or furnace. The outriggers and I-beams are left in place when manufactured homes (mobile homes) are parked. The axles and wheels may or may not be removed. For purposes of property taxation, the terms mobile home and manufactured home are used synonymously.

Residential Personal Property Subclass Code and Description

Residential Personal Property Pers. Code: 1410

A description of this subclass is located under commercial personal property.

Commercial Property

Commercial property includes all lands, improvements, and personal property used as a commercial enterprise. Commercial improved property may have one or more uses.

Hotels and Motels

Hotels and motels are classified, valued, and assessed as lodging property, which is a subclass of nonresidential property unless documentation exists to support a classification as mixed-use property. To be classified as a mixed-use property, the hotel or motel property owner and/or operator must be able to document the use of any portion of the property as residential property. Specifically, evidence of overnight accommodation that is leased or rented for thirty consecutive days or longer by the same person or business entity must be provided. See ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 7, Special Issues in Valuation, for additional information.

Bed and Breakfast Properties

A bed and breakfast (B&B) is a type of overnight lodging establishment as defined by Colorado law:

Definitions.

(2.5) “Bed and breakfast” means an overnight lodging establishment, whether owned by a natural person or any legal entity, that is a residential dwelling unit or an appurtenance thereto, in which the innkeeper resides, or that is a building designed but not necessarily occupied as a single family residence that is next to, or directly across the street from, the innkeeper’s residence, and in either circumstance, in which:

(a) Lodging accommodations are provided for a fee;

(b) At least one meal per day is provided at no charge other than the fee for the lodging accommodations; and

(c) There are not more than thirteen sleeping rooms available for transient guests

§ 39-1-102, C.R.S.

To be considered for this class, the property must first qualify based on one of the following two scenarios:

• A property can be considered for B&B classification if it is used for overnight lodging AND the innkeeper resides on the property, regardless of whether or not the property was originally designed as a single family home. An example of this would be a small apartment house that has been converted to overnight lodging. The key criterion in this situation is that the innkeeper must reside on the property, or
• A property can be considered for B&B classification if it was designed as a single-family residence, such as an old mansion or large house that was once a family home and it is now being used for lodging. In this situation, the innkeeper may reside in the property, or may reside next door or directly across the street.

The difference between these two situations is as follows:

• If the property was NOT originally designed as a residence, the innkeeper must reside on the property.
• If the property was originally designed as a residence, the innkeeper may reside there but also may reside either next door or directly across the street.

In addition to the occupancy requirements described above, a property must meet ALL of the following criteria to be classified as a B&B:

1. Lodging accommodations are provided for a fee; and
2. At least one meal per day is provided at no charge other than the fee for the lodging accommodations; and
3. There are not more than thirteen (13) sleeping rooms available for transient guests.

See ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 7, Special Issues in Valuation, for information regarding valuation of these properties.

Mixed-Use Properties

In the case of an improvement which is used as a residential dwelling unit and is also used for any other purpose, the residential use must be classified as residential and assessed at the prevailing residential assessment rate. Procedures for valuing this kind of property are provided in § 39-1-103(9), C.R.S. Once the residential use has been separated, the commercial use or uses can be determined.

1. When two commercial uses exist after the residential use is extracted, the commercial portion of the property is classified according to the predominant use.
2. When there is no residential use, but two commercial uses exist, the property is classified according to the predominant use.
3. When three or more commercial uses exist, the property is classified as multiple use (2140/2240).

Agricultural Property

Land, structures, and improvements used as a farm or ranch are assigned to the agricultural land and improvements classifications provided. Those agribusinesses which do not meet the definition of a farm or ranch are classified as “all other agricultural” property. See the description of “all other agricultural” property for details.

The value of water rights is reflected in the productive or grazing capacity of the land.

Wind energy rights are not severable from the surface estate, § 38-30.7-103(1), C.R.S.

Agricultural Classification Criteria

Land that meets one or more of the following definitions is classified as agricultural land.

1. Land that is used as a farm or ranch pursuant to §§ 39-1-102(3.5) and (13.5), C.R.S. The land must have been used as a farm or ranch during the previous two years and presently be used as a farm or ranch, Aberdeen Investors, Inc. v. Adams County Board of County Commissioners, 240 P.3d 298 (Colo. App. 2009). As provided in § 39-1-102(1.6)(a)(I), C.R.S., the land can be in the process of being restored through conservation practices if:

   1. The land was placed in a conservation reserve program established under § 01 to 5506, cl. 7, U.S. CONST., or;
   2. A conservation plan approved by the appropriate conservation district has been implemented for a period of up to ten crop years as if the land were placed in such a conservation reserve program.

   The owner of the land used as a farm or ranch can also have a decreed water right to appropriated water or a final permit to appropriated ground water, § 39-1-102(1.6)(a)(IV), C.R.S.

   NOTE: The use of a portion of the land for hunting, fishing, or other wildlife purposes, for monetary profit or otherwise, does not affect the agricultural classification.

2. Forested land that consists of at least 40 acres and is used to produce tangible wood products is subject to a forest management plan, and is not classified as a farm or ranch, § 39-1-102(1.6)(a)(II), C.R.S. Also see §§ 39-1-102(4.3), (4.4), (4.5), and (4.6), C.R.S.
3. Land that consists of at least 80 acres, or less than 80 acres if no residential improvements exist, and that is subject to a perpetual conservation easement if:
   1. The land was classified as agricultural under §§ 39-1-102(1.6)(a)(I) or (II), C.R.S., at the time the easement was granted; and
   2. The grant of the easement was to a qualified organization; and
   3. The easement was granted exclusively for conservation purposes; and
   4. Contemplated future uses of the land are described in the conservation easement.

NOTES: Land designated as agricultural because it is subject to a perpetual conservation easement does not include any portion of the land that is actually used for nonagricultural commercial or nonagricultural residential purposes, § 39-1-102(1.6)(a)(III), C.R.S. Also see §§ 39-1-102(3.2), (8.7), and (13.2), C.R.S.

The land under residential improvements that are integral to the agricultural operation and that are located on land qualifying under numbers one and two above is classified as agricultural. The land under other improvements existing on land qualifying under number one above is agricultural if the improvements are an integral part of the farm or ranch and if the other improvements and the land area are typically used as an ancillary part of the operation, §§ 39-1-102(1.6)(a)(I) and (II), C.R.S.

Illegal use of the land, such as trespass grazing, cannot qualify a parcel for the agricultural classification. See Besch v. Jefferson County Board of Commissioners, 20 P.3d 1195 (Colo. App. 2000).

When a residential improvement is not integral to a farm or ranch, the residential improvement(s) and up to two acres of land under the residence are classified as residential and listed under Property Not Integral to Agricultural Operation (1177 and 1277) or Manufactured Homes Not integral to Agricultural Operation (1278). Land underlying any residential improvements on forest ag land is classified as agricultural land.

Property that is used solely for the cultivation of medical marijuana shall not be classified as agricultural land, § 39-1-102(1.6)(d), C.R.S.

When the productivity of a parcel of agricultural land is destroyed due to a natural cause, the agricultural classification shall remain in place for the year of destruction and up to four subsequent property tax years so long as the assessor receives evidence that the owner is in the process of rehabilitating the land for agricultural use, § 39-1-103(5)(e)(1), C.R.S.

Refer to ARL Volume 3, REAL PROPERTY VALUATION MANUAL, Chapter 5, Valuation of Agricultural Land, for a synopsis of agricultural court cases that may assist in determining if parcels qualify for the agricultural classification.

Colorado Assessment Percentages

Assessors calculate the actual value of property. However, property taxes are based on a property’s assessed value, which is a fixed percentage of the actual value. Assessment percentages differ for residential property, primary production of oil and gas lands or leaseholds, secondary production of these lands or leaseholds, producing mines, and “all other” classifications of property. The General Assembly has the authority to set the assessment rates for all of the classifications of property.

Refer to Chapter 12, Special Topics, for a more complete explanation of the history of the adjustment of the residential rate. It should be noted that the Colorado Constitution prohibits an increase in the assessment rate of any class of property unless the increase is approved at a general election, § 20, art. X, COLO. CONST.

The data below shows the residential rate adjustments as enacted into law from 1982, when the Colorado Constitution was amended to create this requirement.

The following summary lists specific categories of property and their respective assessment percentages.
