Solano County, CA Short-Term Rentals: Night Caps (2026)

Solano County's short-term rental framework is keyed to per-stay length, not to a yearly night cap. Short-term lodging is defined as transient occupancy for a period of 30 consecutive calendar days or less, and a Vacation House Rental is a dwelling offered or used for that transient occupancy without a resident family present. In the County's published VHR program pages, FAQ, and application materials reviewed here, the County's binding constraints are the permit type (Minor Use Permit for a VHR), the zoning district (the use must be allowed where the property sits), fire-hazard-zone limits (not allowed in Very High FHSZ; High FHSZ must meet Section 28.75.30(A)(7)(b)), occupancy (2 per bedroom + 2, max 10), and the operating-permit conditions - not a stated maximum number of rentable nights per year. The County's VHR FAQ does address a minimum-stay question, indicating the program speaks to minimum booking length rather than an annual ceiling. Because we did not see a numeric annual night cap in the County's primary sources, we do not assert one; operators should confirm any stay-length conditions printed on their issued Minor Use Permit. Note that the annually renewed VHR operating permit is an administrative renewal cycle, not a cap on rentable nights.
