Condos make up 28.7% of Atlanta home sales, yet every Georgia appeal guide ignores attached housing. This one doesn't.
# How to Appeal Your Condo or Townhome Property Tax in Georgia
In 2025, condos and townhomes accounted for nearly 28.7% of all home sales in the City of Atlanta, yet virtually every property tax appeal guide online uses single-family home examples exclusively. If you own a condo or townhome in Georgia, that gap matters. The comparable properties are harder to find, the square footage on your tax record may be measured wrong, and the way common areas factor into your assessed value creates confusion that most homeowners never untangle.
The condo townhome property tax appeal process in Georgia follows the same 45-day appeal statute (O.C.G.A. 48-5-311) as single-family homes, but the evidence you need and the arguments that actually win at a hearing are different for attached housing.
Every condo unit in Georgia is assessed as its own separate parcel. O.C.G.A. 44-3-96 is explicit: "No tax or assessment shall be levied on the condominium as a whole but only on the individual condominium units." Your unit gets its own parcel ID, its own assessed value, and its own tax bill.
Like all Georgia property, condos and townhomes are assessed at 40% of fair market value. If the county says your condo is worth $300,000, your assessed value is $120,000, and that's the base your millage rate applies to. Where things diverge is how the county arrives at that fair market value number.
Condo owners don't receive a separate tax bill for the pool, lobby, or parking garage. The value of common elements is already included in each unit's assessment, distributed by your ownership percentage in the condo declaration. You and every other unit owner hold common areas as tenants-in-common under the Georgia Condominium Act.
Townhome communities work differently. The association itself typically owns common areas (sidewalks, detention ponds, clubhouses). Because restrictive covenants render these parcels unmarketable to outside buyers, they should be assessed at nominal value, often under $500. If your townhome HOA is paying significant property taxes on common areas, that cost is flowing into your dues unnecessarily.
Research from the Harvard Joint Center for Housing Studies, NBER, and the Philadelphia Federal Reserve all confirm the same pattern: lower-value properties are systematically overassessed relative to higher-value ones. Because condos tend to have lower per-unit values than single-family homes, they're disproportionately affected.
In Fulton County, the Board of Assessors' own data showed that 41% of residential properties were overvalued in 2025. Assessed values rose 5.9% countywide while actual sale prices rose only 3.7%. Condos, with their smaller price points and fewer clean comps, are especially vulnerable to that kind of gap.
No. Your unit's assessed value already includes your proportional share of common element value. You aren't taxed separately for the hallways, elevators, or parking structure. If you suspect the county is assessing common areas as a separate parcel on top of including that value in each unit, raise it directly with the assessor's office.
For townhome owners, the question is slightly different. Your HOA does pay taxes on association-owned common areas, but those should be assessed at minimal value because covenants prevent the HOA from selling them. If your HOA's common-area tax bill seems high, ask the board to share the assessed value and consider appealing that parcel.
Square footage errors are one of the most common and most correctable problems in condo assessments. For single-family homes, assessors measure from the exterior walls. For condos, the correct measurement is interior wall-to-wall (the livable space within your unit's boundaries). County assessors don't always make that distinction, and exterior measurements can inflate the number by 5-15% depending on wall thickness and shared-wall construction.
Check your county's property record card against your condo's floor plan or closing documents. If the county has you at 1,250 square feet and your closing documents say 1,150, you've found an error that directly inflates your assessed value. This mistake is especially common in older buildings measured before digital floor plans became standard.
A square footage correction doesn't always require a formal appeal. You may be able to file a correction request with the assessor's office directly. But if the correction also means the assessed value should drop, file a PT-311A appeal to lock in the value reduction for the current tax year.
HOA fees are not part of the county's property tax calculation. The assessor doesn't factor in your monthly dues when determining fair market value.
But HOA fees absolutely affect what buyers will pay for your unit, and that's where they become relevant to an appeal. Buyers evaluate total monthly cost of ownership: mortgage plus HOA fees plus property taxes plus insurance. When HOA fees rise, buyers offer less for the unit itself. Metro Atlanta median HOA fees climbed from $108/month in 2019 to $135/month in 2025, a 25% increase according to the Georgia Association of REALTORS. For a condo with $400/month dues (common in full-amenity high-rises), that's $4,800 per year that doesn't build equity.
If your HOA fees are materially higher than average, you can present this as a factor suppressing your unit's market value. The argument is strongest when recent sales in your building already reflect this discount compared to the assessor's model.
Finding good comps for a condo is genuinely harder than for a single-family home. Boards of Equalization give little weight to cross-type comparisons, so using a single-family home sale to argue your condo's value down rarely works.
The single best comparable is a recent sale in the same building. If a unit with a similar layout sold for less than your assessed value, that's powerful evidence. Pull sales from the past 12 months using your county assessor's website, Zillow, or the Georgia MLS.
If your building hasn't had enough recent sales, look for sales in buildings with similar characteristics: same era of construction, similar unit sizes, comparable amenities, and close geographic proximity. Stay within a one-mile radius and match the property type (mid-rise to mid-rise, garden-style to garden-style).
Not all units in a building are equal. Account for differences in floor level (higher floors typically command 1-3% premiums), view quality, renovation status, parking (deeded space vs. none), and outdoor space. If a comparable sold for $345,000 but had a higher floor and renovated kitchen, your original-condition unit should logically be worth less. Make adjustments explicit in your evidence packet.
Three from your building and two from similar nearby properties gives you a solid foundation. Five sales showing a consistent range below your assessment tells a story the board can't ignore.
AppealAlly's Do-It-Yourself Appeal Kit ($79, with a 100% money-back guarantee) includes a comparable sales analysis calibrated for your property type, so condo and townhome owners receive comps that boards actually accept rather than generic single-family defaults.
Over 60% of residential appeals with proper evidence result in reductions, according to REI Valuations, a Georgia-based appraisal firm. For condos and townhomes, "proper evidence" means tailoring your case to the specific characteristics of attached housing.
If your building has identical or near-identical units and some are assessed lower than yours, you have a textbook uniformity argument. Georgia's Constitution requires that "all taxation shall be uniform upon the same class of subjects," and O.C.G.A. 48-5-299(c) establishes uniformity as a standalone ground for appeal.
In a building where every 2BR/2BA unit shares the same floor plan, there's no legitimate reason for a $30,000 assessment gap between your unit and one two floors down. Check the assessed values of comparable units on the county assessor's website and calculate assessed value per square foot. If yours is meaningfully higher, the uniformity argument may be stronger than a value argument.
Request the assessor's comps early. If they used single-family homes or sales from fundamentally different neighborhoods, that undercuts their case and strengthens yours.
Yes. Under O.C.G.A. 44-3-100, a condo association board has broad authority to act on behalf of unit owners. Many Georgia property tax practitioners handle bulk appeals where the HOA board coordinates filings for multiple units.
The important nuance: in most Georgia counties, each unit still requires its own individual PT-311A filing. The association can organize the effort, share the cost of an appraiser, and present evidence collectively, but the paperwork is filed per parcel. Larger associations often hire a single firm to handle all units, reducing per-unit costs significantly.
If you're a board member considering this approach, survey unit owners and check whether a bulk discount is available. AppealAlly's Full-Service Appeal (30% of first-year savings, $0 upfront) can handle individual units within a group effort, removing the financial risk for owners who aren't sure their unit is actually overassessed.
The appeal process for condos and townhomes is identical to single-family homes under Georgia law. No special forms or separate procedures.
Download the PT-311A Appeal of Assessment form and specify your property ID, your estimated fair market value, and your preferred appeal method. For condo and townhome appeals, check both the "value" and "uniformity" boxes if you have evidence supporting both arguments. There's no downside to raising both.
One protection worth knowing: under Georgia law, your assessment cannot be raised as a result of filing an appeal. The worst outcome is your current value stays the same.
A striking 17% of appellants who file never show up. That's an automatic loss. Over 43.5% of Georgia appeals settle before the hearing even takes place, often because the assessor reviews your evidence and agrees to a value adjustment in advance. Show up with your comparable sales and uniformity data, and you have a real chance at a reduction.
A 2BR/2BA condo in a 1990s mid-rise building in Midtown Atlanta, 1,150 square feet, received a 2025 assessment of $375,000 FMV. That was a 12% increase over the prior year.
The owner found three same-building sales between $330,000 and $345,000 in the prior 12 months, plus two sales in a comparable building one block away in the same range. Similar units in the building were assessed at $340,000 to $345,000, while theirs sat at $375,000 with no obvious difference in condition or floor level.
They filed a PT-311A checking both "value" and "uniformity," submitted the five comparable sales and the assessed-value comparison, and attended the BOE hearing.
Result: The Board of Equalization reduced the assessment to $345,000, an 8% reduction.
Financial impact at a 35-mill rate with standard homestead exemption:
Three hours of preparation and one hearing produced $420 in annual savings. With the HB 581 assessment freeze preventing the county from ratcheting the value back up, total savings over three years exceeded $2,300.
Your potential savings depend on where your condo or townhome is located. Millage rates vary significantly across metro Atlanta.
A 10% overassessment on a $365,000 condo translates to annual savings between $250 and $510 depending on your county's millage rate. In higher-tax counties like Gwinnett and DeKalb, even a modest 5-7% reduction compounds meaningfully over multiple tax years.
Two recent changes affect condo and townhome owners:
Georgia Amendment 1 (2024) created a floating homestead exemption that caps assessment growth at the inflation rate. Some counties have opted in (DeKalb, for example) while others have not. If yours participates, a successful appeal locks in a lower base value with ongoing protection.
HB 581 (2025) changed the 3-year value freeze. Previously, filing an appeal alone triggered a freeze. Now, the freeze only applies if your appeal results in an actual reduction. A win today protects you for three years.
Condo and townhome property tax appeals in Georgia follow the same legal process as single-family homes, but the evidence strategy is fundamentally different. The uniformity argument is often your strongest tool because identical units in the same building make unequal assessments obvious. Square footage errors from exterior-wall measurements inflate condo values more than most owners realize. And HOA fees, while not part of the assessment formula, suppress market value in ways that support a lower FMV argument.
The market supports appeals right now. Condo and townhome prices declined 1.5% statewide in 2025 according to the Georgia Association of REALTORS, while many county assessments continued climbing. Intown Atlanta condos sit in a buyer's market with 7 months of supply. If your assessment went up while the market went flat or down, you have a data-backed case.
Check your assessment notice for square footage accuracy, pull comparable sales from your building, and compare your per-square-foot assessed value against similar units. If the numbers don't add up, file that PT-311A before your 45-day window closes. The filing carries zero risk of a higher assessment, and the potential savings compound for years.
