Atlanta ADU Permit Fees & Cost Calculator
Atlanta’s official fee page shows separate permit charges for small residential projects, including mechanical/electrical/plumbing minimum fees and a per-square-foot fee category for one- and two-family residence basement or attic build-outs; however, the city page does not clearly publish a dedicated ADU fee schedule, so exact ADU-specific totals should be verified with permitting staff.[8]

The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
Do not rely on secondary cost estimates for exact permit pricing; confirm with Atlanta Zoning, Development, and Permitting Services.
If the project is in a historic district or triggers additional review, extra fees may apply.
The available official source shows minimum fees and category fees, but not a complete ADU-specific fee worksheet.
The ADU would be reviewed under Atlanta permitting categories that may include building, mechanical, electrical, and plumbing permits.
The official city page excerpt available here does not provide a dedicated ADU fee schedule, so exact total fees are not known from the source material.
Atlanta fee estimates should be verified against the current city, utility, and school district fee schedules before filing.
FAQs
Are Atlanta ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Atlanta?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Georgia?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
