Tiny home rules in Chatham County, GA — 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.
Chatham County has no separate tiny-home ordinance. A site-built tiny house on a foundation is regulated as a dwelling (or ADU) under NewZO and Georgia's building codes; a tiny house on wheels is generally treated as an RV, not a permanent residence.
There is no standalone tiny-home category in Chatham County. A permanent, site-built tiny house on a foundation is treated as a single-family dwelling, or where the NewZO ordinance allows, an accessory dwelling unit under Sec. 8.7.4, and must be built to Georgia's adopted residential building code (room sizes, egress, alarms). Whether a tiny house is a permitted use, and its minimum size, setbacks, and foundation, follows the NewZO zoning district. A tiny house on wheels is generally classified as a recreational vehicle; living long-term in an RV on a residential lot outside a licensed campground is typically not allowed. Because Chatham includes coastal flood zones, elevation and flood-construction rules can also apply. Confirm with the MPC and county building office.
