Barndominiums in Georgia

Outside city limits: Georgia does not run one statewide building permit for rural homes. Permits and inspections come from the city or county building or planning department where the property sits, and each local government decides which state codes it enforces. A rural parcel therefore needs a call to the county (or the city, if inside city limits) to learn whether a building permit and inspections are required. Even where a county does not inspect, the state's mandatory codes still apply to the construction. A septic permit is a separate requirement handled by the county health department.

Georgia sets state minimum standard codes through the Department of Community Affairs (DCA). Nine are mandatory statewide, including the International Residential Code for one- and two-family homes, plumbing, mechanical, fuel gas, electrical and energy codes. State law says mandatory codes apply to all construction in Georgia whether or not a local government enforces them. Day-to-day plan review and inspection are done by local governments (cities and counties) that choose to enforce the codes; they can add local amendments only after submitting them to DCA for review. DCA has announced that the 2024 International Residential Code with Georgia amendments takes effect January 1, 2027. A separate set of permissive codes, such as the disaster-resilient building appendices, applies only where a local government adopts them.

• Georgia's mandatory state codes (building, residential, fire, plumbing, mechanical, fuel gas, electrical, energy conservation, swimming pool and spa) apply statewide; any structure built in Georgia must comply whether or not the local government enforces them. Local governments are not required to adopt them but must have administrative procedures in place to enforce them and may choose which mandatory codes to enforce. source
• Permissive codes (disaster-resilient building code appendices for the IBC and IRC, property maintenance, existing building, National Green Building Standard) can be enforced locally only after the local government adopts them by ordinance or resolution and sends a copy to DCA. source
• Local governments administer and enforce the state minimum codes: they can inspect buildings, employ inspectors, require permits and set permit charges. A local government that enforces a code must enforce the latest edition and amendments adopted by DCA. A proposed local amendment must be submitted to DCA at least 60 days before adoption. source
• DCA announced on December 9, 2025 that the 2024 International Residential Code with Georgia Amendments (along with the 2024 IBC, IFGC, IMC, IPC, ISPSC, 2024 IFC as adopted by the Safety Fire Commissioner, and the 2026 Georgia amendments to the 2023 National Electrical Code) takes effect January 1, 2027. source
• DCA's list of current mandatory codes shows the International Residential Code, 2024 edition, with 2026 Georgia amendments, and the National Electrical Code, 2023 edition with 2026 amendments. source
• Fire, life safety and accessibility rules (Life Safety Code, Georgia amendments to the International Fire Code, Georgia Accessibility Code) are handled by the State Fire Marshal's Office rather than DCA. source

Septic systems in Georgia are regulated by the Department of Public Health (DPH) under Chapter 511-3-1, but permits are issued by the county board of health (county environmental health office). No site work or system installation may begin before the county issues a construction permit. The county must approve or deny a completed application within 20 days. Permits are issued only after a site inspection and a soil evaluation done by a DPH-certified soil classifier (or other approved professional) carrying at least $1 million in liability insurance. Installers must also be DPH-certified. A permit stays valid no more than 12 months. On parcels of three acres or more, a conventional or chamber septic system can be used if the percolation rate is no slower than 120 minutes per inch; smaller lots are sized under county board of health rules.

• No one may begin physical development of a lot or install an on-site sewage system without first obtaining a construction permit from the county health department; the county board of health must approve or disapprove a completed application within 20 days. source
• Construction permits are issued only after a site inspection finds acceptable absorption rates, soils, groundwater and rock conditions. Lots are sized under county board of health regulations and the state manual, and permits remain valid for not more than twelve months from issue. source
• Soil evaluations must be done by individuals certified by the Department, who must attach a liability insurance certificate of at least $1 million. Soil classifiers, septic tank contractors, inspectors, maintenance personnel and pumpers must be state-certified, with certification renewed every two years. source
• On tracts of three acres or more, a conventional or chamber septic system may be used if the percolation rate does not exceed 120 minutes per inch; slower rates are unsuitable unless the application includes a special design. source
• DPH publishes the Manual for On-Site Sewage Management Systems (updated March 2026), lists of certified installers and pumpers by county, and requires Level III soil reports to be prepared by a certified Soil Classifier. source

Georgia's residential energy code is the 2015 International Energy Conservation Code with Georgia amendments, in effect since January 1, 2020 and mandatory statewide, according to the U.S. Department of Energy. Georgia's own amendment packets for the energy code were updated in 2022 and 2023. Builders can show compliance with the REScheck software.

• Georgia's current residential energy code is the 2015 IECC with state amendments, effective January 1, 2020, enforced as mandatory statewide; REScheck can be used for compliance. The page lists no upcoming edition. source
• DCA's list of mandatory codes shows the International Energy Conservation Code as the 2015 edition with Georgia amendments adopted in 2020, 2022 and 2023. source
• DCA's 2022 notice of intent adopted additional Georgia amendments to the 2015 IECC effective September 1, 2022, with further amendments to the 2015 IECC effective January 1, 2023. source

The Georgia Emergency Management Agency (GEMA) calls tornadoes the state's top weather-related killer and says they can occur at any time of year. It suggests homeowners consider a safe room and points to FEMA plans. For the coast and areas inland, GEMA warns that hurricanes can cause catastrophic damage hundreds of miles inland and recommends hurricane shutters or plywood covers for windows. Georgia's optional disaster-resilient building code appendices apply only where a county or city adopts them, so wind and tornado requirements for a new home depend largely on the local building department and the wind provisions of the residential code it enforces.

• GEMA says tornadoes are the state's number one weather-related killer, can strike without warning, and can occur at any time of year. Best shelter is a storm cellar or basement; otherwise an interior room or hallway on the lowest floor. GEMA suggests considering a safe room and points to FEMA for plans. source
• GEMA says hurricanes forming in the Atlantic, Caribbean and Gulf can cause catastrophic damage hundreds of miles inland, and recommends covering windows with shutters or 5/8-inch exterior-grade plywood and keeping a safe room or small interior room on the lowest level. It notes property insurance typically does not cover flood damage. source
• Georgia's permissive codes include disaster-resilient building code appendices for the IBC and IRC; they apply only in jurisdictions that adopt them. source

Property tax

Georgia's Conservation Use Valuation Assessment (CUVA) taxes qualifying farm, forest and environmentally sensitive land on its current-use value instead of market value, in exchange for a 10-year covenant. The state's fact sheet says there is generally a 10-acre minimum (some counties use 25), a cap of 2,000 acres per private owner, no foreign owners, and no non-agricultural commercial business on the land. Breaking the covenant early means repaying twice the tax savings plus interest. Each county tax assessor administers the program and the application is due by the property tax return deadline, usually April 1. The Department of Revenue publishes per-acre values for nine valuation areas each year. Homestead exemption applies to an owner's legal residence and the land under it if owned and occupied on January 1; the standard state exemption is $2,000 off the assessed value for county and school taxes, with more for seniors, disabled veterans and others, and counties can add their own.

• CUVA covenant is 10 years; early breach requires paying back twice the savings received plus interest; if the land is sold, the buyer must continue the covenant or owe penalties. Generally a 10-acre minimum (some counties 25), max 2,000 acres per private owner, foreign citizens and corporations ineligible, and land cannot be used for non-agricultural commercial business. Apply to the county board of tax assessors by the return deadline, usually April 1. source
• Department of Revenue Rule 560-11-6-.09 sets 2023 per-acre current-use values across nine Conservation Use Valuation Areas, by soil productivity class for timber (W1-W9) and agricultural land (A1-A9). source
• Homestead exemption: owner must own and occupy the home as legal residence on January 1; file with the county by the return deadline (historically April 1). State standard exemption is $2,000 from county and school taxes, deducted from the 40% assessed value; additional exemptions exist for ages 62 and 65 with income limits, disabled veterans and surviving spouses. Counties may adopt their own exemptions. source
• A floating homestead exemption authorized by House Bill 581 (2024) is available to local governments and is tied to an annual inflationary index rate; homestead and property tax returns are filed through the county. source

Insurance

Georgia's insurer of last resort is the Georgia Underwriting Association (GUA), also called the FAIR Plan, overseen by the Office of Insurance and Safety Fire Commissioner. According to the Commissioner's guide, it covers buildings and personal property against fire, lightning, windstorm, hail, explosion, riots, smoke, aircraft and vehicles, and on the coast a windstorm-only policy can supplement coverage from insurers that exclude wind. The Commissioner describes it as a last resort because premiums are generally higher and coverage often more limited. The Commissioner's homeowner guidance notes that standard policies usually exclude flood and earthquake and recommends insuring at least 80 percent of replacement value.

• If no insurer will write a property, owners can apply to the Georgia Underwriting Association (FAIR Plan), which covers fire, lightning, windstorm, hail, explosion, riots, smoke, aircraft and vehicles; in coastal Georgia a windstorm-only policy can be written to supplement other insurers' policies that exclude wind. The Commissioner calls it a last resort because premiums are generally higher and coverage more limited. source
• Most homeowner policies do not cover floods or earthquakes, which usually need separate coverage; windstorm is a peril that package policies may cover. Insure for at least 80 percent of replacement value and review coverage yearly. source
• The Commissioner's Property and Casualty section coordinates with the FAIR Plan Governing Committee. source
