Georgia

Georgia's fast-growing metro areas are driving interest in accessory dwelling units as a way to add housing without sprawl. Atlanta adopted an ADU ordinance that has become a model for other cities in the state. ADU Pass helps Georgia homeowners handle the permit paperwork so they can build with confidence.

State ADU details

State financing programs

Georgia does not operate an ADU-specific statewide loan, grant, or forgivable-loan program. The Georgia Department of Community Affairs (DCA) administers the Georgia Dream homeownership program, which includes the Georgia Dream Standard, Georgia Dream Hardest Hit Fund DPA, and (effective 2025-07-01) the Georgia Dream Peach Advantage Loan Program for expanded down-payment assistance. None target ADU construction directly; an ADU-bearing primary residence can qualify for the underlying Georgia Dream first mortgage when other eligibility criteria are met.

State insurance regimes

Georgia operates a residual-market insurer of last resort through the Georgia Underwriting Association (GUA, the state's FAIR Plan), authorized under O.C.G.A. Title 33 Chapter 33. GUA writes basic property and dwelling-fire policies (HO-8 and DP-1 forms) for owners unable to obtain coverage in the admitted market, plus a wind/hail-only policy designation in coastal counties. Coastal Georgia (Bryan, Camden, Chatham, Glynn, Liberty, McIntosh counties plus offshore islands) is defined as the 'Windstorm and Hail Area' under the GUA Plan of Operation, with tighter envelope and documentation standards. GUA recognizes IBHS FORTIFIED Home designations with wind credits of 5% (Bronze), 7.5% (Silver), and 10% (Gold). The Office of Insurance and Safety Fire Commissioner regulates standard homeowners and dwelling-fire products under the Georgia Insurance Code.

  • policy-review (since 2021) — ADU access in Georgia is geographically concentrated in metro Atlanta and a few coastal cities. Practitioners must research each Georgia city and county individually; no statewide floor exists. (source)
Federal (United States) — ADU-relevant rules and programs

Federal ADU law

The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.

Federal financing programs

Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.

Federal tax credits

There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.

Federal housing programs

HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
