What are the tiny house laws in Georgia?

Georgia allows site-built and modular tiny homes that meet building codes and have local siting approval¹. Before choosing land, check whether your home meets construction standards and whether the local government approves its placement¹. Local zoning can control your home's foundation type, building size, lot size, height and location¹.

Georgia's mandatory construction codes apply even where the local government does not enforce them⁵. You get no exemption from those state standards in a county without local code enforcement⁵. Ask the local building office which construction documents and approvals your proposed home needs. For state code questions, ask the Georgia Department of Community Affairs Construction Codes program⁶.

You need a different approval route for a tiny home on wheels in Georgia than for a site-built house¹. Georgia's DCA says mobile-ready tiny homes on trailer chassis are typically classified as recreational vehicles or park models¹. DCA says RVs are intended for recreational or seasonal use only¹. That guidance does not give you permission to use an RV as your permanent home¹.

Local planning and zoning ordinances control where you can place RVs, park models and tiny homes on wheels¹. Before buying a home on a trailer, ask the local planning office about full-time occupancy at the exact address. Ask separately about placing your home and living in it. A seller's description of the home does not give you approval.

Georgia's tiny-house guidance uses a typical definition of 400 square feet or less, excluding lofts¹. That definition gives you no statewide right to build a home of that size¹. Local zoning can set minimum building and lot sizes¹. Before paying for plans, ask the local planning office for the minimum home size in your parcel's district.

We could not confirm one statewide minimum total home size for Georgia. Ask DCA's Construction Codes program about the current residential code and applicable tiny-house appendix⁶. Georgia code appendices need a qualifying reference or adoption to be enforceable⁵. Do not assume an appendix in an older tiny-house brochure applies to your project. Ask the local building office for the applicable code edition and the language adopting it.

Your manufactured tiny home needs different approvals from a modular or site-built tiny home in Georgia³. A qualifying manufactured home must meet applicable federal HUD standards³. Georgia's manufactured-home rules include a minimum size of 320 square feet³. Ask the seller for your home's legal classification before treating a factory-built home as a manufactured home.

A licensed installer must get a state installation permit for each new or pre-owned manufactured home installed in Georgia³. The state installation permit costs $60 per home³. Local zoning, siting and utility requirements still apply³. Ask separately about local building, site and septic charges. The state installation fee does not cover your entire project.

Your tiny house needs an approved sewage system under Georgia's onsite sewage rules⁴. The County Board of Health must find your site suitable before issuing a septic construction permit⁴. Georgia also requires septic permits and inspections for repairs, replacements and additions to existing systems⁴. Do not assume an existing tank gives you approval for your proposed home.

A Georgia onsite sewage construction permit lasts no more than 12 months⁴. You must connect to public or community sewer when available within 200 feet of the property line or in an abutting public right-of-way⁴. Ask the county environmental health office whether your site is suitable before committing to the land. DPH directs local service and inspection questions to that county office⁷. Bring your proposed home layout and explain how you plan to live there.
