Property Tax Appeal
DeKalb County Residential Appraisal & Property Tax Appeal — Decatur, Brookhaven & Dunwoody
Independent market evidence for DeKalb County homeowners appealing their Annual Notice of Assessment — from intown Decatur and Brookhaven to suburban Dunwoody and Stone Mountain.
Appeal Window: DeKalb County property owners generally have 45 days from the date on their Annual Notice of Assessment to file an appeal. This is based on standard Georgia procedure — always verify the exact deadline printed on your own notice and file with DeKalb County Board of Tax Assessors — dekalbcountyga.gov/departments/property-appraisal before ordering an appraisal.
DeKalb County's housing market ranges from small, in-demand historic bungalows near Decatur and Brookhaven to larger suburban homes around Dunwoody, Tucker, and Stone Mountain — each with very different renovation levels, lot characteristics, and buyer demand. When your Annual Notice of Assessment doesn't reflect your property's actual condition or comparable sales, an independent appraisal provides the specific evidence a general assessment can't.
Understanding Your Notice
Understanding Your DeKalb County Assessment
Who Sets Your Value
The DeKalb County Property Appraisal Department (Board of Tax Assessors) values property and issues Annual Notices of Assessment. The Tax Commissioner's Office is a separate department that handles billing and collections once values are finalized — it does not have authority over your assessed value.
Like every Georgia county, DeKalb County assesses residential property at 40% of fair market value for tax purposes. An appeal challenges the county's opinion of fair market value — exactly what an independent appraisal is built to evaluate.
Your Tax Bill vs. Your Assessment
Your actual property tax bill combines county, DeKalb County School District, and — for properties inside a city — municipal millage rates, along with any homestead exemptions filed. Cities such as Decatur, Dunwoody, Brookhaven, Chamblee, Clarkston, and Avondale Estates each levy their own municipal millage separately from the county and school system, so identical assessed values inside and outside city limits can produce noticeably different bills. An appraisal speaks to fair market value — the figure actually being appealed — not the tax calculation.
When It May Help
Common Reasons DeKalb County Assessments Get Questioned
Your property may be getting compared to homes that aren't truly similar in DeKalb County's market.
Needed repairs or condition issues aren't factored into the county's valuation.
A listed improvement or upgrade on your property record may simply be incorrect.
The size of this year's increase isn't supported by actual sale prices in DeKalb County.
Local Appeal Process
How to Appeal in DeKalb County
DeKalb County property owners must file within 45 days of the mailing date on their assessment notice — a strict deadline that isn't extended for online system issues or high traffic. You can file online using the 10-digit access code on your notice, or mail a written appeal to the Property Appraisal Department at 325 Swanton Way, Decatur (faxed or emailed appeals are not accepted). Your filing should include your parcel ID, property address, phone number, supporting documentation, and your chosen appeal avenue.
You can typically file through the DeKalb County Property Appraisal online filing system. Georgia Valuation Source provides independent appraisal evidence for your case — we do not file appeals or provide legal representation.
Board of Equalization
A free, three-member panel of trained local property owners appointed by the Grand Jury. You may appeal on value, uniformity, or exemption grounds. Decisions can be further appealed to Superior Court.
Hearing Officer
Available for non-homestead properties or properties valued over $500,000. Involves a state-certified appraiser; no filing fee.
Non-Binding Arbitration
Requires a certified appraisal of the property submitted at the owner's expense, plus a filing fee (recently $217).
After You File
The Board of Equalization is one of three available appeal avenues in DeKalb County — a three-member panel of trained local property owners appointed by the Grand Jury, with no cost to file. If you remain unsatisfied with the BOE's decision, you retain the right to a further appeal to Superior Court. Note that DeKalb's Board of Assessors can request additional review time (up to 180 days) in years when total appeal volume is unusually high.

What Evidence Matters
Recent closed sales of genuinely comparable homes — similar size, age, condition, and location — with the differences between those homes and yours accounted for individually.
Photographs and a description of any condition issues, deferred maintenance, or functional problems the county's mass-appraisal model would not have observed.
Documentation of the property's physical characteristics (square footage, lot size, room count, systems age) if it differs from county records.
A clear, professionally organized opinion of value — not just a lower number, but the market evidence and reasoning behind it.

DeKalb is Georgia's second-most-populous county, split between dense in-town neighborhoods bordering Atlanta and Emory/Decatur, and a patchwork of newer, separately-incorporated cities (Dunwoody, Brookhaven, Chamblee, Tucker, Stonecrest, Clarkston) each with its own municipal character.

Residential Appraisal Considerations in DeKalb County
Highly fragmented municipal landscape: DeKalb has incorporated more new cities than any other Georgia county in the past two decades (Dunwoody, Brookhaven, Tucker, Stonecrest, etc.), each with a distinct housing stock and zoning approach, so comparables should generally stay within one municipality rather than crossing city lines.
Dense in-town vs. outer-county contrast: Neighborhoods near Emory/Decatur and inside I-285 carry very different lot sizes, home vintages, and teardown/infill activity than areas near Stonecrest/Lithonia outside the perimeter.
DeKalb-Peachtree Airport (PDK) proximity: One of the nation's busiest general-aviation reliever airports sits within the county in Chamblee, and nearby residential parcels can be subject to noise/height-related considerations distinct from the rest of the county.

Local Market Considerations
DeKalb County Market Diversity
DeKalb spans some of Metro Atlanta's most varied residential markets in a single county — dense, walkable, quickly-appreciating neighborhoods inside Decatur and Brookhaven, alongside larger-lot suburban communities around Dunwoody, Tucker, and Stone Mountain. Renovation quality and lot premiums vary widely block-by-block in the intown areas especially, which makes generalized county valuation curves particularly prone to mismatching an individual property's true market value.
