Operating a short-term rental in unincorporated Sonoma County requires a Vacation Rental Permit from Permit Sonoma. The regulations are highly restrictive, with strict zoning requirements, prohibitions on ADUs and guest houses, and density caps in popular areas like the Russian River. The process is lengthy and expensive, involving a public notice period and adherence to strict performance standards for noise, parking, and occupancy.
To host an Airbnb in unincorporated Sonoma County, you must first get a Vacation Rental Permit, which is a long and expensive process. Before you even apply, check the county's zoning maps to see if your property is eligible, as many areas, especially high fire-risk zones, are excluded. You cannot rent out an ADU or guest house. Be prepared for a high application fee (over $2,900) and a process that can take months. Once approved, you must display your permit number on your listing and follow strict rules on guest limits, noise (quiet hours are 10 PM to 7 AM), and parking.
