STR Cost Segregation in Los Angeles, CA
Los Angeles STR cost segregation: build the study around actual home-sharing rooms and dates. Review local resources, study records, and a property-specific planning example.
Build the study around actual home-sharing rooms and dates
Los Angeles City Planning provides a home-sharing records portal and renewal resources. Match the registered property and permitted operation with the rooms and dates in your own records. Los Angeles home-sharing resources.
Define the property study
A host may rent a bedroom, the main living area during travel, or different areas at different times. Record those changes instead of using one annual whole-house percentage without explanation. Separate personal décor from guest-only furnishings and identify any improvements made before the home-sharing activity began.
Records that resolve the main questions
- Home-sharing registration and room-use history
- Owner travel and guest booking calendar
- Furnishing receipts labeled by room and actual use
A scoping example
A resident rents a spare room most months and the whole dwelling while traveling. A sofa serves the household throughout the year while a new bed serves the rented room. Present those differences to the preparer before applying any rental allocation.
Does a home-sharing registration make the entire residence depreciable?
No. The preparer must evaluate actual rental and personal use. Registration is operating documentation, not a determination of the eligible basis or deduction.
Prepare for a Stratum study
Stratum provides nationwide property-study services, with discovery calls through AE Tax Advisors. Confirm the engagement scope, fee, evidence requirements, and CPA handoff. A service-area page does not represent a local office. Local operating approval and federal depreciation are separate questions.

California’s 2025 Form 3885A instructions identify differences between federal and state depreciation, including additional depreciation under section 168(k). Use the relevant year’s guidance and your entity’s filing instructions rather than assuming a federal first-year deduction produces the same state deduction. For a converted home or mixed personal and rental use, establish the basis and use allocation before asking the provider to analyze components.
