Unincorporated Napa County has some of the strictest STR regulations in California, effectively prohibiting new vacation rentals in the majority of Agricultural and Residential zones. Permitted units are mostly limited to specific commercial zones or legally non-conforming properties that were established before current bans.
If you're looking to rent out your property for short periods in Napa County, be aware that the rules are quite strict. In the unincorporated areas of the county, short-term rentals are generally not allowed. Within the City of Napa, you'll need a permit to rent out your place for less than 31 days, and you typically must live on the property as your primary residence. Also, the number of permits available is limited, so there may be a waitlist.
