California county RV zoning for temporary housing

California counties govern zoning in unincorporated areas, while incorporated cities set their own ordinances. Check your property's jurisdiction before relying on county rules. The 9 counties we have researched show that local zoning is the working layer—most prohibit RV occupancy outside designated parks unless a conditional use permit, temporary permit, or disaster exception applies.

California does not have a single statewide statute preempting local RV occupancy bans after disasters. Instead, post-disaster temporary housing allowances are typically authorized through county or city emergency ordinances, often tied to a state or local emergency declaration. Among the 9 counties we have researched, 5 document explicit post-disaster exceptions or temporary housing programs in their ordinances or emergency management frameworks (such as post-wildfire or post-earthquake provisions). If your home is damaged by fire, flood, earthquake, or other disaster, contact county planning and emergency management to learn whether a temporary RV occupancy allowance is in effect.
