Short-term rentals (STRs), locally often referred to as vacation rentals, in Napa County are regulated, with strict limitations on their legality. In the city of Napa, short-term rentals are legal but require a permit, where only hosted rentals (owner-occupied properties) and a limited number of permits are allowed each year. Conversely, short-term rentals are prohibited in the unincorporated areas of Napa County, including cities like Calistoga and Yountville, where they are entirely banned. This regulatory environment tends to favor guest accommodations in neighborhoods that cater to tourists, particularly those seeking unique stays in rural settings or near wine country, although some urban apartment rentals also exist. The overall market favors tourism, with properties thriving during peak wine tourism seasons and popular events, though there is some demand from business travelers as well. The Napa County Planning, Building and Environmental Services Department oversees the regulations affecting short-term rentals.
