Operating an STR in unincorporated San Diego County requires a Short-Term Rental Permit from Planning & Development Services and a Transient Occupancy Tax (TOT) Certificate. The regulations focus on neighborhood preservation, with strict occupancy limits (2 per bedroom + 1, max 10), quiet hours, and a requirement for a local contact person. ADUs and JADUs are explicitly prohibited from being used as STRs.
To host an Airbnb in the unincorporated areas of San Diego County, you must get a Short-Term Rental Permit from the county, which costs $250 initially and requires annual renewal. You'll also need to register for the 8% Transient Occupancy Tax and file quarterly returns, even if Airbnb collects the tax for you. Be aware that you cannot rent out an ADU or guest house, and you must have a local contact who can get to the property within an hour, 24/7. Make sure to post your permit number on your listing and follow the strict guest limit of 2 people per bedroom plus one, up to a maximum of 10 guests.
