You are four weeks from listing and you have just learned the finished basement was never permitted. Maybe the previous owner did the work. Maybe your own contractor promised to pull the permit and closed out the job without one. Either way, a buyer's agent will ask about it, and you have to decide what to do before the sign goes in the yard.
Here is the plain answer. You can sell a metro Atlanta home with unpermitted work, but you cannot hide it. The City of Atlanta requires a permit for basement and attic finishes, conversions, alterations, and additions to a single family residence, and permit history is a public record any buyer, agent, or lender can pull. Under Fannie Mae Selling Guide B4-1.3-05, the valuation professional the lender hires must comment on an addition built without the required permit, its quality, its appearance, and its effect on market value. That comment is where the money consequence shows up.
What counts as unpermitted work on an Atlanta home
Owners tend to assume the permit line is drawn at structural work. It is drawn much earlier. The question is not how big the project felt, it is what the jurisdiction lists as a permitted activity.
The residential permits the City of Atlanta actually requires
The residential permit types the City of Atlanta Office of Buildings issues include a new single or duplex family residence up to three stories, an addition to a single family residence, demolitions, deck additions, basement and attic finishes, conversions, alterations, retaining walls, and accessory sheds. The city also notes that some items are exempt from being permitted, which is why a rule of thumb is a poor substitute for reading the list. Both the permit types and the submission process are set out on the City of Atlanta residential permitting page.
Applications go to the Department of City Planning with architectural, structural, and site plans, and the city publishes checklists by permit type so an applicant can see what a complete package looks like. All permit types must now be submitted online through the Accela Citizen website, except Express permits, which are only accepted in person. One more requirement matters if your scope touches a mature tree. Since June 25, 2025, projects affecting trees require an arborist meeting with Office of Buildings staff before the application is submitted, a separate track covered in our post on removing a tree before you list or renovate an Atlanta home.
Why basement finishes are the most common gap
Basement finishes generate permit gaps for reasons that have nothing to do with intent. The work happens below grade, out of view from the street. It is often done in phases, a framed room this year, a bathroom the next, so no single stage feels like a project needing plan review. It is also the category most likely to go to a handyman rather than a contractor who pulls permits as a matter of routine.
The result is a house with real, usable square footage and no paper trail behind it. The work being good is not the same as the work being documented, and only one of those survives contact with a lender.
How to find out what was permitted before you list
Do this before you price the home and before you choose a path. You cannot evaluate the options until you know what the record says.
Pulling the permit history in Accela Citizen Access
City of Atlanta permit records are searchable by the public through Accela Citizen Access, the same platform the city now uses for submission and status tracking. Search your address and read every record, not just the most recent. You are looking for what was applied for, what was issued, what inspections were recorded, and what final status each record carries. Assume a buyer's agent will run the same search. A permit history you found in week one is a fact you can plan around; the same history found in week two of a due diligence period is a renegotiation.
What the record looks like when a permit was opened and never closed
There is a third state between permitted and unpermitted. A permit was pulled, the work was done, and the final inspection never happened, so the record reads as open or expired rather than completed.
That is often cheaper to resolve than work with no permit at all, because the application, the approved plans, and any completed inspections already exist in the file. It is still an open item a buyer can point to. Ask a licensed contractor what closing it would require under current review standards.
The three paths, and what each one costs
Sellers in this position generally choose among three routes. None is the default correct answer. The right choice depends on the specific work, the county and municipality the property sits in, the condition of what was built, your listing calendar, and advice from a licensed contractor and your own Georgia attorney.
Permit it retroactively before listing
This path converts an unknown into a document. You engage a licensed contractor, produce plans that match what was actually built, submit through Accela, and carry the work through inspection to a closed permit. On city fees alone, the minimum cost for a permit is $150 plus a $25 technology fee, with the full schedule published in the City Code of Ordinances. Design, correction, and construction costs sit on top and depend on what inspection reveals, which is why a contractor walkthrough comes first. The real variable here is not fee, it is calendar. Plan review, inspection scheduling, and corrective work all take time you may not have before your target list date.
Disclose it and price it in
The second path is to leave the work as it stands, disclose it, and let the market price the uncertainty. What a seller must reveal is a legal question for your attorney, not a marketing decision. Our overview of Georgia's updated seller disclosure form explains what the form asks and where it fits in the transaction.
The trade here is speed for spread. You list on schedule, and in exchange buyers price in a risk they cannot size, while a financed buyer's lender may treat the square footage differently than your listing does.
Remove or reverse the work
The third path is to take the work out. It is the least common route, and it applies mainly where an inspection finds conditions that would be costly to correct in place, or where the unpermitted element is small and removable. It trades finished square footage for a clean record, and a contractor should scope it first, because removal carries its own permit and inspection implications.
What the lender's valuation report does with undocumented square footage
For a financed buyer, the lender's valuation report is where unpermitted work stops being a disclosure item and becomes a number.
The Fannie Mae comment requirement
Fannie Mae Selling Guide B4-1.3-05 sets the standard. In substance, when the valuation professional the lender hires identifies an addition that does not have the required permit, that professional must comment on the quality and appearance of the work and on its impact, if any, on market value. Note what the rule does not say. It does not automatically strike the space. It calls for a written judgment about build quality, appearance, and value effect, made in person. Two homes with identical unpermitted square footage can therefore land in different places, which is one more reason a contractor's assessment is useful even if you never pull a permit.
Why gross living area is the number to watch
The practical exposure is the gross living area figure the report settles on. If part of your finished space is excluded from it, the comparable set changes, and a contract price built on the larger number has to be renegotiated or covered by the buyer. Our post on what to do when the valuation comes in below the contract price covers the options from there.
The code change that raised the stakes in 2026
Georgia's 2024 IRC adoption, effective January 1, 2026
The Georgia Department of Community Affairs Board, acting on the recommendation of the State Codes Advisory Committee, voted to adopt a new set of codes with an effective date of January 1, 2026. The adopted set includes the 2024 International Residential Code with Georgia Amendments, the 2024 International Building Code with Georgia Amendments, the 2024 International Plumbing Code, the 2024 International Mechanical Code, the 2024 International Fuel Gas Code, the 2024 International Swimming Pool and Spa Code, and the 2026 Georgia Amendments to the 2023 National Electrical Code.
What a current-code review means for older work
The consequence for a retroactive permit is direct. Work you permit this fall is reviewed against a code edition that took effect in January, not the edition in force when the work was built. Basement finishes touch electrical, plumbing, mechanical, and egress provisions, so a multi-year-old finish can be measured against several updated code books at once. A contractor working from the currently adopted editions can tell you what that means for your space.
Sequencing this against a fall listing calendar
Timing matters because the metro is moving at a specific pace. Per the Atlanta REALTORS Market Brief for July 2026, the eleven-county metro posted a July median sales price of $445,000, up 2.1 percent year over year, on 4,824 sales, down 12.0 percent from June, against 20,863 active listings, a 4.7-month supply, and 24 days on market on average.
Read those figures as context, not as a forecast. That supply level describes a market where a buyer has alternatives and time to use them, and an unresolved permit question is an easy reason to pause. Working backward from a fall list date, the history pull takes days, a contractor walkthrough takes days, and a retroactive permit takes considerably longer than either. Run them in that order.
FAQ
Does finishing a basement in Atlanta require a permit? The City of Atlanta Office of Buildings lists basement and attic finishes, conversions, and alterations among the residential permit types it issues, and also notes that some items are exempt from being permitted. Confirm your scope against the published permit types and with a licensed contractor before assuming either way.
How do I check my home's permit history? City of Atlanta permit records are searchable by the public through Accela Citizen Access, the same portal where all permit types must now be submitted. Search by address and review every record on file, including any issued but never finalized. Do this before you set a list price.
What happens in the lender's valuation report if there is an unpermitted addition? Fannie Mae Selling Guide B4-1.3-05 requires the valuation professional the lender hires, upon identifying an addition without the required permit, to comment on the quality and appearance of the work and its impact, if any, on market value. That is a documented judgment, not an automatic exclusion, and the practical effect varies with the condition of the work.
What code will a retroactive permit be reviewed under? Georgia's mandatory state minimum standard codes changed effective January 1, 2026 to the 2024 International Residential Code with Georgia Amendments, along with the other 2024 model codes adopted at the same time. A permit pulled now is reviewed against that current edition, not the edition in force when the work was done.
What does a City of Atlanta residential permit cost? The minimum cost for a permit is $150, plus a $25 technology fee, with the complete fee schedule published in the City Code of Ordinances. Design, correction, and construction costs are separate and depend on what your scope of work requires.
Get the permit picture before you price the house
We can start with a pre-listing walkthrough and a permit-history pull on your address, so the record is in front of you rather than in front of a buyer's agent first. From there we will run a market analysis two ways, with the disputed square footage counted and without it, so you see the real spread between the paths instead of guessing at it. If a net sheet is more useful right now, we will build that instead.
Bring a licensed contractor in for scope and cost, and your own Georgia attorney for disclosure questions. Our role is the market side: what the record shows, what comparable homes are doing, and how each path reads to the open market. Reach out to The Agency Atlanta to get started.
