Stratum Cost Segregation · Updated September 27, 2026

Separate operator furnishings from a building owned by someone else

San Francisco’s Office of Short-Term Rentals administers the city’s residential rental regulations. Verify the operator and dwelling records with that office and distinguish them from property ownership documents. San Francisco Office of Short-Term Rentals.

Define the property study

A resident host may own the dwelling or occupy it under a lease. Before a study is scoped, establish which improvements and furnishings the host owns and whether any costs were reimbursed. Building-wide values cannot simply be assigned to a resident who only purchased room furnishings.

Records that resolve the main questions

A scoping example

A tenant buys beds and removable shelving while the building owner renovates the kitchen. The host’s inventory should distinguish those purchases from the landlord’s work. A shared mailing address does not establish a common owner of every asset.

Illustrative documentation scenario; not a completed client study or a savings estimate.

Does business registration establish a depreciable interest in the building?

No. Have the preparer evaluate ownership and the actual costs incurred. Registration supports operating compliance; it does not replace title or lease evidence.
