Everything Park City short-term rental owners need to evaluate cost segregation: how much you actually save, what changes by neighborhood, where the regulatory traps are, and when the strategy doesn't work.
For a typical Park City short-term rental, cost segregation produces a median $90,760 Year-1 federal tax deduction at the 37% top marginal bracket with 100% bonus depreciation. The range across 5 representative Park City fixtures spanning $1,100,000–$2,400,000: $53,660 to $115,726.
The reclassification ratio — the share of your depreciable basis the engine moves from 27.5-year (or 39-year) into accelerated 5/7/15-year recovery — ranges from 17.3% to 26.9% depending on property type, neighborhood, build year, and STR vs LTR rental mode.
Park City is the cleanest cost-seg market in the Wasatch — and one of the cleanest in the country — for three reasons that don't apply to most ski towns. First, Utah conforms to federal §168(k), so the 100% bonus depreciation that OBBBA permanently restored in 2025 reduces both your federal and your Utah liability in the same year, with no addback. California buyers relocating equity to Park City are getting a real tax-rate uplift, not just a postponement of pain.
Second, the property mix is unusually heterogeneous for a ski market. Deer Valley's resort-tier basis is dominated by land — engine reconciliation factors run high and 5-year personal property shows up mostly through FF&E density. Old Town's 1890s–1920s mining-era homes, by contrast, often have heavy renovation costs layered onto modest original basis — renovation cost segregation does meaningful work here. Park Meadows family SFRs sit in the middle: lower land allocations, longer hold profiles, and a cleaner material-participation story because Park Meadows owners more frequently self-coordinate STR operations rather than relying on full-service management. (Note: personal use of the property carries §280A vacation-home limitations that can complicate STR-loophole treatment — material participation under §469 should be documented through hours of active management, not nights of personal stay.)
Third, the Nightly Rental Business License regime is unusually clear. Park City's municipal code (Title 4) separates short-term nightly rentals from long-term residential leases, and licenses are tied to the property address rather than the operator. That predictability removes a class of regulatory risk that markets like Joshua Tree, Nashville, and NYC keep generating. The downside: the city is actively enforcing license requirements, and your cost-seg study's hold-period assumptions should match the license term, not your business plan.
Utah conforms to federal §168(k), so 100% bonus depreciation under the One Big Beautiful Bill Act applies for both federal AND Utah state tax. There is no state addback. Park City cost-seg deductions reduce both your federal and your Utah income tax liability in the same year.
Verify with your CPA. State tax conformity for federal §168(k) is adjusted frequently. Framing reflects our understanding as of May 2026 — always verify current-year treatment with a qualified tax professional before relying on specific dollar projections.
State income tax structure: Flat single rate (2024 tax year onward). Bonus depreciation addback required: No.
What this means in practice: your federal cost-seg deduction also reduces your Utah state income tax liability in the same year, with no addback or recapture mismatch. This is the cleanest tax position possible for cost-seg.
Park City cost-seg ROI varies more by sub-market than by city. Here's what each neighborhood's profile looks like:
Typical value: $2,800,000 · Typical land allocation: ~38%
Resort-tier ski-in/ski-out at Deer Valley Resort. High land allocation (resort land scarcity premium) suppresses the depreciable basis as a percentage of purchase — but absolute basis is still large. Best fixture profile: $2M–$5M condo or chalet.
Typical value: $1,650,000 · Typical land allocation: ~32%
Historic mining-era SFRs and townhomes within the Park Avenue, Main Street, and Empire Pass corridors. Heavy renovations often layered onto 1890s–1920s bones — renovation_cost blocks meaningfully bump short-life reclassification.
Typical value: $1,450,000 · Typical land allocation: ~25%
Off-mountain family SFR market. Larger lots, 1990s–2010s builds dominate. Lower land allocation = more depreciable basis per dollar. Sweet spot for STR-converted family homes.
Typical value: $1,200,000 · Typical land allocation: ~28%
Resort condo stock at the Canyons base. Vertical density reduces effective land allocation. Best fit for the $800K–$1.5M condo buyer.
Typical value: $1,100,000 · Typical land allocation: ~22%
Outside Park City limits — long-term rental crossover. Lower entry, weaker STR margins but easier permitting. Material participation cleaner because tenant turnover is annual rather than weekly.

Park City Nightly Rental Business License. Operating an STR in Park City requires a Nightly Rental Business License from the city's Business Services Office, with a separate Type 1 (residential) or Type 2 (resort/zoned commercial) designation depending on parcel zoning. License renewals are annual; the license is tied to the property, not the operator. Material participation under §469 requires >100 hours of active management AND more than any other person — Park City's professional property-management ecosystem means tracking this carefully matters more here than in markets where owners self-manage. Summit County assessor data is publicly searchable at SummitCountyUtah.gov; we cross-reference recorded sales basis and land allocations against engine outputs as a QC step.

Honest framing matters. Cost segregation is the wrong move when:
Indirectly. The license itself doesn't change the cost-seg study's component analysis or MACRS classification. But it affects two upstream assumptions: (1) hold-period economics, because licenses are tied to property addresses and renewed annually, so a buyer whose STR plan assumes 10+ years of nightly-rental income should verify the license history before relying on those projections; (2) material participation under §469, because Park City's professional property-management ecosystem means owners often delegate operations, and the 100-hour/more-than-anyone test gets harder. We assume conservative 5-year hold profiles in Park City advisory ranges unless an owner can document active management.
No. HOA dues are ongoing operating expenses, deductible against rental income in the year incurred. They never become part of your depreciable basis. What CAN go into basis: capital assessments levied by the HOA for shared infrastructure (e.g., a special assessment for a new HVAC plant, paving, or pool replacement). Those are capitalized as additions to your basis and depreciated over the same schedule as the original property — and a cost-seg study can sometimes reclassify portions of HOA-funded capital improvements into shorter recovery periods if you can substantiate your pro-rata share of identifiable 5/15-year components.
Higher than the regional average — but only if the renovations were capitalized rather than expensed at the time. Old Town homes often see effective reclassification ratios in the 26–34% range when the original 1890s–1920s structure has had a substantial post-2000 renovation. The mechanics: original-build structural components don't reclassify well (most are integral to the long-life building), but the renovation cost (new electrical, HVAC, finishes, FF&E, landscaping, decking) is where the 5- and 15-year work happens. The engine treats renovation_cost as a separate allocable pool with its own MACRS distribution — for a heavily renovated Old Town SFR, that pool often contributes 60–80% of the total accelerated component.
It can be, if you self-manage and document your hours. The IRS test for whether short-term rentals get out of the §469 passive-loss bucket is twofold: average customer use under 7 days (or under 30 days with personal services), AND you materially participate (one of 7 tests, but the practical ones are >500 hours OR >100 hours and more than any other person). For Park City owners who use a professional management company, the second test typically fails — the manager spends more time than you do. The path that works: self-manage cleaning coordination, guest communication, and maintenance directly via an app like Hospitable or Hostfully; track hours; bias toward stays under 7 days. Confirm with your CPA before assuming STR-loophole treatment.
Three different profiles. Deer Valley: highest absolute Y1 savings dollars but lowest savings-as-percent-of-purchase, because land allocation is 35–40% (resort-land scarcity premium). Canyons Village: middle on both axes — lower land allocation than Deer Valley (vertical condo density helps), middling FF&E density per square foot. Park Meadows: best percent-of-purchase ROI because land allocation is closer to 22–27%, and family-home FF&E density is high once you furnish for STR use (sleeps-12 layouts, multiple full baths, hot tub, smart-home additions). For a $1.5M purchase, the median engine output is around 27–32% reclassification in Park Meadows vs 18–22% in Deer Valley.
