Solano County, CA Short-Term Rentals: Occupancy Limits (2026)

Solano County publishes a specific occupancy formula for Vacation House Rentals (the non-hosted short-term rental category) on its VHR program page. Maximum occupancy is up to two (2) guests per bedroom, plus two (2) additional guests per property, up to a maximum of ten (10) guests, not including children under three (3) years of age. A VHR is defined by the County as a dwelling that is offered or used for transient occupancy without a resident family present within the dwelling. Because occupancy is keyed to bedroom count, smaller homes carry proportionally smaller caps - a two-bedroom VHR, for example, would compute to six guests (4 + 2) rather than the 10-guest ceiling.

The 10-guest figure is an absolute maximum regardless of bedroom count. The Hosted Rental category is a different product: it is defined as a single guest room offered for transient occupancy and is therefore inherently smaller. Occupancy limits are enforced as conditions of the operating permit, and exceeding the approved guest count is a permit violation. The County did not, in its published VHR materials reviewed here, set a separate numeric daytime-visitor cap distinct from this overnight formula.
