Restrictions
San Francisco operates California's most restrictive major-city STR framework. The operator must reside in the unit at least 275 nights per year (verified annually). Unhosted STR is capped at 90 nights per year; hosted STR (operator present) is uncapped. The Office of Short-Term Rentals registration fee is ~$1,075 every two years. Operating without registration triggers up to $1,000 per day in administrative fines. Rent-stabilized units, BMR (below-market-rate) units, and units in buildings with Ellis Act invocations are categorically banned from STR.
