Tiny home rules in Gwinnett County, GA β covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds β determine where they are legal and how they get permitted.
Tiny homes on permanent foundations in unincorporated Gwinnett must meet the Georgia Residential Code minimum dwelling standards, zoning minimum dwelling size (if any), and setback rules. Tiny homes on wheels (RVs/THOWs) are not legal as permanent dwellings.
Gwinnett regulates tiny homes under the same rules as other single-family dwellings. Permanent tiny homes on foundations must comply with the Georgia Residential Code including IRC Appendix Q (Tiny Houses) for dwellings 400 square feet or less, which provides relaxed ceiling, loft, and stair standards while maintaining egress, smoke detectors, and structural requirements. The home must connect to approved water, sewer/septic, and electrical utilities. UDO minimum dwelling size and zone density controls apply: some residential zones may effectively preclude tiny homes via minimum square footage or lot size requirements. Tiny homes on wheels (THOWs) built to ANSI/RVIA RV standards are considered recreational vehicles and cannot be used as permanent dwellings in residential zones; they can only occupy licensed RV parks or be stored per RV parking rules. Manufactured tiny homes with HUD certification follow manufactured housing rules. Check the current UDO for minimum dwelling size in your zone before planning a tiny home build.
Non-compliant tiny homes: cannot obtain certificate of occupancy; stop-work orders; RV-built units cannot be occupied as dwellings; fines.
