Solano County, CA Parking Rules: Overnight Parking (2026)

Solano County does not impose a citywide overnight parking prohibition (for example, a 2 a.m. to 5 a.m. ban) on its unincorporated roads. The governing local provision is Section 6.5-36, which prohibits parking or leaving a vehicle standing on any street, highway, public road, or thoroughfare in the unincorporated area for 72 or more consecutive hours. Because the trigger is 72 continuous hours rather than the time of day, a single overnight stay on a County road is not, by itself, a County parking violation. The County may still act sooner under Chapter 6.5 if the vehicle is abandoned, wrecked, dismantled, or inoperative, or if it is presumed abandoned under California Vehicle Code Section 22523. Living or sleeping in a vehicle or RV parked on private property as a dwelling is separately constrained by zoning, which does not allow recreational vehicles as permanent dwellings outside permitted situations. On private property, an owner may generally park overnight, subject to the inoperative-vehicle 10-day limit in Section 6.5-14 and any private HOA rules the County does not enforce. As always, posted signs and state law take precedence.
