San Francisco strictly regulates short-term rentals, requiring hosts to be permanent residents who live in their unit for at least 275 days per year. While hosted rentals (where the host is present) are unlimited, unhosted rentals are capped at 90 days per calendar year.
To host an Airbnb in San Francisco, you must live in the home you are renting for at least 9 months out of the year. You need to register for a Business License first, then apply for a specific STR permit which costs $700 every two years. If you are staying in the house with your guests, there is no limit on how many nights you can host, but if you rent out the entire place while you are away, you are limited to 90 nights per year.
