NOT PUBLISHED PURSUANT TO C.A.R. 35(e)
Announced March 26, 2026

Gary Shaffstall, Pro Se

Heidi Miller, County Attorney, Meredith P. Van Horn, Assistant County
Attorney, Brighton, Colorado, for Respondent-Appellee

Philip J. Weiser, Attorney General, Krista Maher, First Assistant Attorney
General, Denver, Colorado, for Appellee
¶1 Petitioner, Gary Shaffstall (Shaffstall), appeals the final agency

order issued by the Board of Assessment Appeals (BAA) determining

the actual value of his property for the 2023 tax year. We affirm.

I. Background

¶2 Shaffstall owns a manufactured home that is considered real

property (the property). In 2023, the county assessor assigned a

value of $254,000 to the property. Shaffstall appealed the initial

value to the County Board of Equalization (CBOE), which adjusted

the value to $200,000.

¶3 Unsatisfied with the CBOE’s adjustment, Shaffstall appealed

the revised valuation to the BAA. There, he argued that the

property value should be assessed based on the cost, as opposed to

the market, approach, so the actual value of the property should be

$80,000. The BAA issued its final agency order rejecting

Shaffstall’s request to apply the cost approach and valued the

property at $187,500. Shaffstall now appeals.

II. Standard of Review and Applicable Law

¶4 Decisions made by the BAA are subject to judicial review

under the State Administrative Procedure Act, section 24-4-106(11),

C.R.S. 2025. § 39-8-108(2), C.R.S. 2025; Jefferson Cnty. Bd. of

1
Cnty. Comm’rs v. S.T. Spano Greenhouses, Inc., 155 P.3d 422, 424

(Colo. App. 2006). It is the BAA’s role “to weigh the evidence and

resolve any conflicts,” but a reviewing court may set aside the BAA’s

decision “if it is unsupported by competent evidence or reflects a

failure to abide by the statutory scheme for calculating property tax

assessments.” S.T. Spano Greenhouses, Inc., 155 P.3d at 424. And

the BAA’s interpretation of statutes is a question of law that we

review de novo. Id.

¶5 Manufactured or mobile homes are designed for residential

occupancy, see § 24-32-3302(20)(b), (24), C.R.S. 2025, but are

generally taxed as personal property, see Leader Fed. Bank for Sav.

v. Saunders, 929 P.2d 1343, 1353 (Colo. 1997) (analyzing taxation

of manufactured homes as personal property and real property). If

a manufactured home is permanently affixed to the ground,

however, it is considered “purged,” meaning the mobile home title

converts to real property and it is taxed accordingly. § 38-29-

118(2), C.R.S. 2025; Saunders, 929 P.2d at 1353 (holding that

owners of purged manufactured homes are required to pay

residential property taxes).

¶6 In Colorado, property appraisals must be based on either the

market approach, the cost approach, or the income approach.

Colo. Const. art. X, § 3(1)(a). But assessors are required to use the

market approach to determine the “actual value” of real property.

Colo. Const. art. X, § 20(8)(c). Under the market approach, actual

value is equal to market value. Xerox Corp. v. Board of Cnty.

Comm’rs, 87 P.3d 189, 193 (Colo. App. 2003) (“[A]ctual value is

synonymous with market value.”). And market value is “what a

willing buyer would pay a willing seller under normal economic

conditions.” Id. (quoting Bd. of Assessment Appeals v. Colo. Arlberg

Club, 762 P.2d 146, 151 (Colo. 1988)). Accordingly, the market

approach involves “analyz[ing] the sales of comparable properties in

the market.”1 S.T. Spano Greenhouses, Inc., 155 P.3d at 425.

1 “The cost approach involves adding the estimated value of the land

to the current cost of constructing a reproduction or replacement
for the improvements and then subtracting the amount of
depreciation.” Jefferson Cnty. Bd. of Cnty. Comm’rs v. S.T. Spano
Greenhouses, Inc., 155 P.3d 422, 425 (Colo. App. 2006). The
income approach involves “a calculation of the income stream the
property is capable of generating, capitalized to value at a rate
typical within the relevant market.” Id.

III. Analysis

¶7 Shaffstall argues that the BAA erred in its property valuation

because it incorrectly interpreted Colorado law and did not use the

cost approach. We are not persuaded.

¶8 The BAA did not err by rejecting Shaffstall’s request to use

section 39-1-103(13)(c), C.R.S. 2025. We acknowledge that section

39-1-103(13)(c) states that assessors should use the cost approach

for appraisals. But that subsection relates solely to personal

property, not real property. See § 39-1-103(13)(a)-(c) (referring to

the “appraisal of personal property” and the “assessment of taxable

personal property”); see also Xerox Corp., 87 P.3d at 193 (analyzing

“the appropriate basis to assess personal property under

§ 39-1-103(13)”). Because Shaffstall purged his manufactured

home in 1999, the property converted to real property and,

therefore, needed to be taxed as such. See § 38-29-118(2).

¶9 Shaffstall asserts a theory as to why his property value has

increased so significantly. Though it is not completely clear, he

appears to allege that investors fraudulently bought homes in the

area and then sold them at much higher prices, leading to inflated

home values. But even assuming there was fraud or collusion with

4
companies or individuals purchasing mobile homes in his area,

Colorado law requires the BAA to determine the property’s actual

value by using the market approach because it is considered real

property. See § 39-1-103(5)(a). And Shaffstall does not dispute

that his mobile home was purged in 1999.

¶ 10 We also conclude that the BAA’s valuation of the property is

supported by the record. The county presented as evidence an

assessor’s appraisal report that included three comparable sales of

purged manufactured homes. Based on the comparable sales, the

assessor came up with a value range between $187,578 and

$255,176. The assessor indicated that the property was most

similar to the comparable at the lowest end of the range and

recommended the property be valued at $187,500. Shaffstall did

not provide comparable sales contesting the assessor’s valuation,

such as comparables of similarly situated mobile homes that had

5
not been remodeled or upgraded, supporting his valuation of

$80,000.2 Accordingly, we will not disturb the BAA’s order.

IV. Conclusion

¶ 11 The BAA’s order is affirmed.

JUDGE PAWAR and JUDGE GOMEZ concur.

2 We acknowledge that Shaffstall provided a quote for the purchase

of a 2024 manufactured home, but it does not comply with the
statutory requirements for valuation under the market approach.
Generally, under the market approach, comparable sales are
gathered from a “base period” that is eighteen months “prior to July
1 immediately preceding the assessment date.” § 39-1-104(10.2)(d),
C.R.S. 2025. And the assessment date is January 1. § 39-1-105,
C.R.S. 2025. Accordingly, for the tax year 2023, the base period is
January 1, 2021 through June 30, 2022.
