What this means for you

To host an Airbnb in Unincorporated Mariposa County, you must apply for a specific Vacation Rental Permit which costs $587 as a one-time fee. You must also register for a tax certificate to pay the 12% Transient Occupancy Tax every quarter. Be aware that most areas require you to have a landline telephone for guest safety because cell service is unreliable, and you cannot use yurts or RVs as rentals. Only one vacation rental permit is allowed per owner.
