Tiny home rules in Richmond, CA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
California HCD guidance and Health and Safety Code 18007 classify many tiny homes on wheels as manufactured housing or ADUs, granting statewide siting protections.
Health and Safety Code sections 18007-18014 define when a structure qualifies as a manufactured home, mobilehome, or recreational vehicle. Tiny homes built to HUD code or ANSI 119.5 standards may be sited as ADUs under Government Code 66310 et seq. (formerly 65852.2) if they meet ADU dimensional rules and are placed on a permanent foundation. RV-classified tiny homes are generally limited to mobilehome and RV parks. HCD information bulletins address movable tiny houses, and some cities adopt their own movable-tiny-house ordinances, but there is no standalone statewide siting right for tiny homes on wheels.
Improper siting outside ADU or RV-park rules may trigger zoning enforcement; HCD enforces manufactured housing standards statewide.
