Tiny home rules in Grass Valley, 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 govern manufactured homes and define when a structure qualifies as a mobilehome, manufactured home, or recreational vehicle. Tiny homes built to ANSI 119.5 or HUD code may be sited as ADUs under Government Code 65852.2 if they meet ADU dimensional rules and are placed on a permanent foundation. RV-classified tiny homes are restricted to mobilehome and RV parks. State law also covers movable tiny houses through SB-477 and HCD information bulletins, providing a uniform regulatory framework.
Improper siting outside ADU or RV-park rules may trigger zoning enforcement; HCD enforces manufactured housing standards statewide.
