ADU details

ADU legality: with-restrictions

Stateunclear (Georgia has no statewide ADU statute; OCGA Title 36 Chapter 66 (Zoning Procedures Law) delegates land-use authority to local governments) — Georgia delegates ADU regulation entirely to local governments. State minimum building code is the Georgia amendments to the 2024 IRC (effective 2026-01-01); IRC R313 residential sprinkler mandate is removed by GA amendment.
Countywith-restrictions (Augusta-Richmond County is a consolidated city-county since 1996; there is no separate Richmond County zoning) — Augusta and Richmond County operate as a unified consolidated government. The Augusta-Richmond County Planning & Development Department administers zoning and building permits for all parcels in Richmond County (excluding the small enclaves of Hephzibah and Blythe which retain limited municipal authority). Augusta rules are county rules.
Citywith-restrictions (Comprehensive Zoning Ordinance of Augusta-Richmond County (Title 8 Planning and Zoning, consolidated November 2019)) — Augusta's Comprehensive Zoning Ordinance does not create a dedicated 'ADU' use type. Accessory dwelling-style structures are accommodated through accessory-building rules in residential zones (R-1, R-1A, R-1B, R-1C, R-1D, R-2) where permitted, or via the duplex/multifamily zones (R-3A/B/C). Owner-occupancy of either the primary or accessory unit is generally expected per local practice. Confirm zoning, setback, and use determination with Planning & Zoning before design.

Augusta has no purpose-built ADU ordinance; ADUs proceed via accessory-building plus residential use determinations on a case-by-case basis. Historic-district overlays (Olde Town, Summerville, Pinch Gut, Bethlehem, Laney-Walker) and Savannah River floodplain are the chief gating reviews.

Permitting process

Typical duration75 days
Backlog21 days
  1. Confirm zoning, overlay, and historic-district status (~5d)
    Verify the parcel's zoning classification under the Augusta-Richmond County Comprehensive Zoning Ordinance (R-1/R-1A/R-1B/R-1C/R-1D, R-2, R-3 most common for ADU candidates). Check Olde Town, Pinch Gut, Summerville, Bethlehem, and Laney-Walker historic-district overlays via the Historic Preservation Commission map. Pull a Floodplain Determination from Augusta GIS for parcels near the Savannah River, Rae's Creek, Rocky Creek, or Butler Creek.
  2. Plot plan and site survey preparation (~10d)
    Augusta-Richmond County Planning & Development requires a residential plot plan with the permit application for any new construction, addition, or detached structure. Plot plan must show lot dimensions, principal dwelling, proposed ADU footprint, setbacks, driveway, and utility tie-ins. Surveyor stamp recommended on infill or near-setback projects.
  3. Historic Preservation Commission review (if in historic district) (~35d)
    If parcel falls within Olde Town, Summerville, Pinch Gut, Bethlehem, or Laney-Walker, file a Certificate of Appropriateness with the Augusta Historic Preservation Commission. HPC reviews materials, massing, fenestration; cycle typically 30-45 days with monthly meetings.
  4. Submit building permit application via CityView Portal (~1d)
    Register and file through the CityView Portal at cityview.augustaga.gov/cityviewportal. Residential building permit application PDF and the New Residential Packet are downloadable from augustaga.gov/2101/Building-Permits. Required: site/plot plan, foundation and floor plans, elevations, energy compliance per 2024 IECC GA amendments (for permits filed 2026-01-01 onward), structural engineer stamp where loads exceed prescriptive IRC.
  5. Plan review (Building, Zoning, Engineering, Health) (~28d)
    Concurrent review by Augusta-Richmond Construction Division (2024 IRC GA amendments), Planning & Zoning (zoning conformance and use determination), Engineering (storm drainage, driveway tie-in, right-of-way), and East Central Health District for any private septic. ePlan Review accepts digital submittals. Two to three correction cycles typical for a first-time ADU applicant.
  6. Pay permit fees and issue permit (~3d)
    Pay building permit, plan review, and any zoning compliance fees per the Augusta-Richmond Fee Schedule (DocumentCenter/View/19493). Augusta Utilities Department assesses water/sewer connection charges separately. No state ADU impact fee.
  7. Construction inspections
    Footing/foundation, framing, rough MEP, insulation, and final inspections scheduled through the CityView Portal. Inspector turnaround typically 1-2 business days.
  8. Certificate of Occupancy (~5d)
    Augusta-Richmond Construction Division issues the CO once final inspection clears. ADU is then eligible for occupancy and rental.

County ADU ordinance

Georgia state — ADU law and programs

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.

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.
