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 of Los Angeles Home-Sharing Ordinance: Short-term rentals (stays under 30 days) are generally restricted to a host's primary residence, with annual cap on hosted-stay nights and registration/permit requirements. Non-primary-residence STR operation is largely prohibited in LA city limits. This is the single most important regulatory fact for cost-seg planning in LA — absentee STR strategies do not translate from Joshua Tree, Palm Springs, Tahoe, or other §469-loophole markets. Adjacent jurisdictions with different regimes: West Hollywood (permits available), Burbank (some areas permit), Pasadena (limited permits). Verify jurisdictional boundaries carefully — addresses on the same block can fall under different regulatory regimes. For non-STR investor strategies (fix-and-flip, small MF, ADU), there is no STR ordinance to manage; standard rental property §469 passive-loss rules apply, and real-estate-professional status is the typical path to active treatment for high-volume LA flippers.
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.
