Tiny home rules in Fremont, 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.
Fremont allows tiny homes as ADUs if built to California Residential Code on a foundation. Tiny homes on wheels are regulated as RVs and generally cannot be primary dwellings.
Fremont recognizes two tiny home categories. Fixed tiny homes built to the California Residential Code on a permanent foundation are treated as ADUs under Government Code 65852.2 and are permitted on any residential lot, provided they meet minimum ADU habitability standards: at least 150 square feet with a separate bathroom, kitchen with a sink and cooking appliance, heating, and smoke/CO alarms. Movable Tiny Houses (MTH) built to ANSI A119.5 can qualify as ADUs in some California cities but Fremont requires full CRC compliance or HUD manufactured home certification. Tiny homes on wheels (THOW) built as RVs are regulated under Vehicle Code and can only be parked, not occupied as a primary dwelling, on residential lots. Long-term RV habitation is prohibited outside licensed RV parks.
