San Francisco distinguishes hosted stays (host present overnight) from unhosted stays (host absent). Unhosted rentals are capped at 90 nights yearly while hosted stays have no annual cap, encouraging genuine home sharing over de facto hotels.
Under Police Code 41A.5(g), a hosted stay is one where the registered primary resident sleeps at the property during the guest's visit. These hosted nights count toward the 275-night occupancy proof but face no annual booking limit. Unhosted stays, where the host is traveling or otherwise absent, are capped at 90 nights per calendar year. The OSTR tracks both categories through quarterly host reports and platform data feeds required under the platform liability ordinance. Exceeding 90 unhosted nights triggers automatic deregistration and a one-year ban from re-applying.
Going over 90 unhosted nights triggers registration revocation, a one-year reapplication ban, $484 daily fines, and tax reassessment.
