Can this property be a vacation rental?

What decides it

Sonoma County settles this parcel by parcel, and four separate tests all have to pass. The property has to sit in the unincorporated county rather than inside one of the nine cities. The base zone has to permit a vacation rental. The parcel has to carry no Vacation Rental Exclusion combining district and fall outside the county’s mapped prohibit area. And the buyer has to obtain a permit and a license in their own name after closing.

The zoning standard is Sonoma County Code Chapter 26, Article 28, Section 26-28-160, moved there from Section 26-88-120 by Ordinance 6386 in August 2022. The exclusion and cap overlays are in Article 79. Licensing is Chapter 4, Article VIII, adopted May 2023.

Where the zoning allows it

Permit Sonoma permits vacation rentals in the Coastal Zone and in certain AR, RR and PCRR parcels; in existing single-family residences in the C2, LC and K districts; and in certain LEA, DA and RRD parcels.

Where it is not allowed at all

• R1, R2 and R3 residential districts.
• Land under a Williamson Act contract in an agricultural preserve.
• Land Intensive Agriculture (LIA).
• Accessory dwelling units, in every zone.
• Farm family housing, agricultural employee housing and farmworker housing.
• Yurts, tiny homes on wheels and other temporary structures, and any non-habitable structure.

Exclusion districts and the prohibit area

Two different overlays can end the question before zoning is reached. The Vacation Rental Exclusion (X) combining district is the first. Section 26-79-010 allows every use the base zone permits except a new vacation rental, and Permit Sonoma states the consequence without qualification: no further applications are accepted inside an exclusion area. The county’s exclusion layer carried 25 exclusion polygons and 12 cap polygons when this page was written. They concentrate in Sonoma Valley — Glen Ellen, Kenwood, Boyes Hot Springs, Sobre Vista and their neighbors — and along the lower Russian River. The most recent additions, Trinity Oaks in Glen Ellen and Carriger Road in Sonoma, took effect August 16, 2024 and covered 388 parcels.

The prohibit area is a separate county dataset that maps the parcels where a vacation rental is not an allowed use in the first place. It is broad. Screening the county’s own layer parcel by parcel puts it at roughly 44 percent of the county. A parcel inside it is finished regardless of what the base zone says.

The caps, and what they are today

Section 26-79-020 lets the Board cap vacation rentals at five or ten percent of the single-family dwellings inside a district, with the fraction rounded down. Every cap the Board has actually applied is five percent. Twelve communities carry one. All twelve are over it.

Over cap means nothing new issues. Buying a house in one of these twelve that is operating as a vacation rental today does not change that — the seller’s permit dies at close, the community is still over its cap, and any slot that eventually opens goes to the county’s waiting list in order. Twenty-one people were on that list countywide when this page was written.

What happens to the permit when the property sells

It ends. A county vacation rental is authorized by a zoning permit, and a zoning permit runs with the owner rather than with the land. Permit Sonoma says it plainly for exclusion areas: existing legally permitted vacation rentals may continue, but their permits expire upon sale or transfer of the property. The license does not convey either. It is issued to a property owner, expires one year from issuance, and the licensing ordinance contains no transfer provision.

This is the single most expensive misunderstanding in the market. A listing that advertises rental income is describing the seller’s permit, not an asset that comes with the house. Where the parcel is otherwise eligible, a buyer can apply for their own and usually get one. Where it sits in an exclusion district or an over-cap community, the income stops at close and cannot be restarted.

Getting a new permit

Four steps, in order. Become or hire a Sonoma County Certified Vacation Rental Property Manager, which requires passing a county certification exam. Apply for the Transient Vacation Rental zoning permit with a scaled site plan and floor plan. Register with the Auditor-Controller Treasurer-Tax Collector for a transient occupancy tax number. Then apply for the vacation rental license with proof of ownership, and renew it every 365 days.

One vacation rental per parcel, and one licensed vacation rental per owner, with an exception for rentals legally operating before June 16, 2023. Transient occupancy tax in the unincorporated county is 12 percent.

The nine cities

A city address is decided by the city, and most of Sonoma County’s cities are closed to investors.

• Sonoma — no new vacation rentals since December 2017. Existing licensed rentals may continue. The only exception is adaptive reuse of a historic structure.
• Healdsburg — rentals under 30 days are prohibited in every residential zone. The only path is the downtown commercial district with a use permit.
• Santa Rosa — not accepting new non-hosted applications. The cap is 182 and shrinks by attrition. Hosted rentals are allowed citywide where the owner is the principal resident.
• Windsor — hosted only in residential districts; non-hosted rentals there are prohibited outright. The license is non-transferable and does not run with the land.
• Petaluma — non-hosted rentals are permitted in residential, PUD and mixed-use zones, for no more than 90 days in a calendar year.
• Sebastopol — whole-house rentals are allowed with an administrative permit up to 30 rental days a year, and a conditional use permit above that.
• Cloverdale — hosted rentals in residential zones by plot plan review; non-hosted only in commercial zones with a conditional use permit.
• Rohnert Park — single-room hosted rentals only. Whole-house and ADU rentals are prohibited.
• Cotati — confirm directly with the city. No current ordinance text is published, and the secondary sources disagree.
