Georgia applies mandatory state construction codes statewide and separately regulates industrialized/modular and HUD-code manufactured housing. Those construction pathways do not override local zoning, subdivision, foundation, utility or land-use decisions.
“Tiny house” is a lifestyle description. Regulators care about the legal building or vehicle classification.
Georgia’s mandatory state construction codes apply statewide. The 2024 International Residential Code with Georgia amendments became effective January 1, 2026, but the local government still handles the applicable permit, zoning and site-development decisions.
Georgia’s Industrialized Buildings Program covers qualifying factory-built housing and requires state construction compliance/insignia. DCA expressly says the program does not supersede local zoning and that local governments retain site-installation, subdivision, grading, foundation and utility authority.
Georgia’s manufactured-housing program treats manufactured homes as dwelling units of at least 320 square feet built on a permanent chassis under HUD standards. A state installation permit is required for each new or pre-owned manufactured home installed in Georgia.
A tiny house on wheels should not be assumed to qualify for Georgia’s industrialized-building or HUD manufactured-home pathways. Confirm the exact classification and local zoning/occupancy treatment before relying on a vehicle-style unit for full-time residence.
Community acceptance does not replace zoning, building, utility or other government approvals. Confirm both the community rules and the legal pathway for the specific unit.
