The cost segregation benchmarks, calculators, and FAQs on this site are informational only. They are not tax, legal, accounting, or investment advice. Cost segregation outcomes vary by property, ownership structure, tax position, and current law. Consult a qualified CPA, tax attorney, or financial advisor before making decisions based on information from this site.
The per-fixture engine outputs shown on the benchmarks page represent the engine's output for representative property scenarios. Real customer studies use real property data, real assessor records, and real renovation history, outputs for your specific property may be higher or lower. The illustrative Year-1 federal savings figures assume the 37% top marginal bracket and 100% bonus depreciation; actual savings depend on your taxpayer profile.
City and County of Denver Short-Term Rental Ordinance: STR operation is restricted to a host's primary residence with annual registration. Non-primary-residence STR is largely prohibited in Denver city limits. Adjacent jurisdictions with different regimes: Jefferson County (Lakewood, Wheat Ridge, Arvada), no city STR ordinance applies; Adams County (Westminster, Thornton), varies; Arapahoe County (Cherry Creek South, parts of Aurora), varies. STR-intent buyers should verify the property's specific incorporation status. For non-STR investor strategies (fix-and-flip, small MF, ADU LTR), Denver's primary-residence STR restriction is irrelevant, standard §469 passive-loss rules apply, and real-estate-professional status is the typical path to active treatment for high-volume operators. Denver's ADU expansion (2018 zoning amendment plus 2023 expansion) supports detached and attached ADU construction in most SFR zones; ADU rentals operate under standard residential rental rules.
We re-verify regulatory facts quarterly and refresh the timestamps at the bottom of each page. Despite this, regulations change frequently. Before relying on regulatory statements for a specific decision (license status, hold-period planning, material-participation strategy), verify with the relevant authority.
