Summary

Maximum overnight occupancy for Vacation House Rentals in unincorporated Solano County is set by the County as a condition of the VHR operating permit issued under Chapter 28 of the Solano County Code. Occupancy is sized to the dwelling — based on bedroom count and on-site parking, water/septic capacity, and fire-safety considerations — rather than a single fixed countywide number, and the approved maximum is printed on the permit and required to be posted inside the rental. Owners may not advertise or accept bookings exceeding the permitted maximum. The County also limits daytime guests (visitors beyond overnight occupants) by permit condition to prevent gatherings that overwhelm parking and septic systems, and a minimum stay of two consecutive nights applies. VHRs are prohibited entirely in RR-2.5, RR-5, and RR-10 districts and in High/Very High Fire Hazard Severity Zones, regardless of occupant count.
