Vacaville, CA Short-Term Rentals: Host Presence Rule (2026)

Solano County's short-term lodging structure is built around whether a resident family is present, which is exactly the host-presence question. The County's category definitions divide dwellings occupied by a resident family from those not occupied by one. In the hosted/owner-occupied tier: a Hosted Rental offers a single guest room for transient occupancy, with or without meals (the single-room bed and breakfast concept), authorized by an Administrative Permit under Land Use Regulation 28.72.40(B)(5); a Bed and Breakfast Inn and an Agricultural Homestay are owner-occupied properties renting rooms to a small number of guests. In the non-hosted tier: a Vacation House Rental is 'a dwelling that is offered or used for transient occupancy without a resident family present,' which means the host is not required to be on-site during the stay; the VHR is instead authorized through a Minor Use Permit with conditions. So Solano County does not impose a single countywide host-presence mandate - it lets operators choose a hosted product (host present) or a non-hosted VHR (host absent), each with its own permit. Operators should still provide a responsible local contact and the County-required Good Neighbor materials so complaints can be addressed promptly.
