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 Big Bear Lake operates an active STR permit system with annual renewal requirements, neighborhood density caps, occupancy limits, and noise/parking compliance triggers that can revoke permits for repeat violations. Permits are tied to properties and have transfer-on-sale procedures. Unincorporated San Bernardino County (Big Bear City, Sugarloaf, parts of Fawnskin) operates a county-level STR registration with lighter restrictions. STR-intent buyers should verify jurisdictional boundaries and permit status before closing — addresses on the same road can fall under different regulatory regimes depending on incorporation lines. Material participation under §469 is achievable for self-managing operators, but Big Bear has a well-developed full-service property-management ecosystem (Big Bear Cool Cabins, Destination Big Bear, RedAwning local affiliates) and most owners use professional management, which makes the >100-hour-and-more-than-anyone test difficult to clear.
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.
