No city in Sonoma County is currently open to new vacation rental permits on regular single-family homes. Healdsburg, Sonoma, and Windsor have outright bans, and Santa Rosa's distance-between-rentals requirement is maxed out across the city. If you want to buy a single-family home and run it as a vacation rental in Sonoma County, you are almost certainly looking at unincorporated areas, plus two narrow exceptions inside the cities for mixed-use zoning and commercial B&B licenses.
That is a different answer than most online guides will tell you, and it is the one that matters. The county and its cities have spent the past several years tightening short-term rental rules, and the simple summary is that the door to new single-family city permits is now closed.

The Four Sonoma County Cities and What They Actually Allow
Healdsburg banned new vacation rental permits for regular single-family homes inside city limits. Existing permits are grandfathered for as long as the current owner holds them, but the city stopped issuing new ones years ago. Sonoma (the city, not the county) has done the same. Windsor banned new single-family permits as well.
Santa Rosa is the city that surprises people. On paper it is still open, but the city requires a minimum distance between vacation rentals, and that buffer is now satisfied across essentially the entire city. The practical result is the same as a ban: no new permits for standard residential properties.
So when someone says "I want to buy an Airbnb in Healdsburg" or "I want a vacation rental in Santa Rosa," the city-limits answer for a regular single-family home is no, unless they are looking at a mixed-use zoned property near the commercial district.
Unincorporated Sonoma County is Where Eligibility Lives
The vast majority of vacation rental eligible single-family homes for sale today are in unincorporated parts of Sonoma County. That means parcels that are inside the county but outside any city's boundaries. A few areas to know.
The Russian River corridor (Guerneville, Monte Rio, Forestville, and the resort communities along the river) has historically been the heart of Sonoma County's vacation rental market and still holds the largest pool of eligible properties. Eligible supply has tightened, and that scarcity is pushing rents on qualifying Russian River homes higher.
Alexander Valley, Dry Creek, and the rural pockets surrounding Healdsburg offer wine country backdrops and qualifying parcels at higher price points. Glen Ellen, Kenwood, and the country roads outside Sonoma city do the same at the southern end of the county. Occidental and the rural west county appeal to buyers who want a quieter, more bohemian setting.
In each of those areas, eligibility is not automatic. The parcel needs the right zoning, it cannot sit inside an exclusion zone, and if it is in a cap area, the 5% cap on vacation rentals has to have headroom. That is the math that decides whether a specific property qualifies. Our 7-step guide to Sonoma County rental rules walks through how to check each filter on a specific parcel.
Two Narrow Paths into a Vacation Rental Inside the Cities
There are two paths into a vacation rental inside a Sonoma County city. Neither is common, but both exist.
The first is a property with mixed-use zoning, typically near a city's commercial district. The commercial-residential overlay zoning that defines these areas allows short-term rentals where the standard single-family residential zoning across the rest of the city does not. When one of these comes up, it gets attention quickly.
The second is a property with a commercial bed and breakfast license. A B&B license is a different category of permit than a residential vacation rental permit, and it does transfer with the home when it sells. That makes B&B properties an attractive way into a market that is otherwise closed.

Why This Matters More than Buyers Realize
Vacation rental permits do not transfer with the sale on residential properties. The new owner has to apply for a brand new permit, and the property has to qualify under the rules in place at the time of application. So even if a Healdsburg single-family home is currently operating as a profitable Airbnb, that permit ends when the home is sold. And because Healdsburg is closed to new single-family permits, the new owner cannot replace it.
That is why "which towns allow vacation rentals" is not really the right question for buyers. The right question is which specific parcels are eligible today, in which unincorporated areas, with which zoning, inside which cap and exclusion zones, plus the small set of mixed-use and B&B properties that qualify inside the cities.
