West Marin homeowners who operate Airbnbs and other short-term rentals must apply for licenses by July 1 or forfeit their ability to remain in business. That is the date that the county will implement its new S.T.R. regulations, which it approved last year after a two-year moratorium on new registrations that sought to ease impacts on workforce housing. There are currently 130 people on a waiting list who will replace owners who do not renew on time. Through attrition, the county will gradually implement its new caps on S.T.R.s in coastal villages, with limits varying from community to community. (Dillon Beach is exempt from the limits.) In addition to obtaining an S.T.R. license, homeowners must renew their business license by the end of July. The county imposed the new rules to slow the loss of long-term rentals, which have become scarcer and more expensive in recent years, forcing long-term residents to move away. Anyone who had a legally registered S.T.R.—meaning they had a business license and transient occupancy tax certificate—by Jan. 1, 2024 will be eligible to obtain a new S.T.R. license, provided their septic system meets county requirements. The number of licenses available to those on the waiting list will depend on how many existing operators leave the market or fail to obtain a license by July 1.
