Dunwoody occupies the northern tip of DeKalb County, wrapped around the Perimeter Center office district where I-285 meets Georgia 400, though most of its 51,758 residents live on wooded residential streets a short drive from the towers. The city only incorporated in 2008, but its neighborhoods date back decades, and they now carry some of the heaviest assessments in the county. The median Dunwoody home is worth about $602,900, roughly 68 percent above the DeKalb County median of $357,800, and that gap matters because the county values every neighborhood with mass-appraisal models, and those models get less reliable at the top of the market. Across DeKalb County as a whole, home values stretch from roughly $237,245 at the 25th percentile to $559,874 at the 75th, which means a typical Dunwoody house sits above three quarters of the county before an appraiser ever opens the file. DeKalb's effective property tax rate runs about 1.75 percent, among the steeper county rates in metro Atlanta, and Dunwoody homeowners give up about 4.5 percent of household income to property taxes, well above what most Georgians pay even with a median household income of $121,903. When a mass appraisal overshoots a high-value house, the error scales with the price, so a modeling miss that barely registers elsewhere costs a Dunwoody owner real money year after year. Georgia law gives you 45 days from the date printed on your annual assessment notice to challenge the number, and once that window closes the value locks in for the year.
Dunwoody Appeal Quick Facts
The median home in Dunwoody is valued at $602,900, and the typical homeowner pays about $5,454 per year in property tax (Census ACS 2024), based on DeKalb County's 4.379% combined millage applied to 40% of fair market value after exemptions. That means the typical Dunwoody homeowner spends 4.47% of household income on property taxes alone. Dunwoody combines higher-than-average home values with a heavy tax burden. If your home is overassessed by even 10%, the cost adds up fast. Higher home values mean a larger tax bill and a bigger payoff from a successful appeal. At $602,900, Dunwoody home values are 68% above the DeKalb County median, 254% above Georgia's statewide median of $170,200, 89% above the national median of $318,000.
Check If Your Dunwoody Home Is Overassessed
Brookhaven leads DeKalb County in home values, but your individual assessment could still be too high regardless of where Dunwoody falls in the county ranking.
With a population of 51,758, Dunwoody has plenty of recent sales to draw from. The strongest evidence is 3-5 comparable sales: homes similar to yours in size, age, and condition that sold recently for less than your assessed value. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.

Based on a combined tax rate of 4.379%. Your actual rate may vary by tax district.
A 10% reduction on the median Dunwoody home ($602,900 down by $60,290) would save approximately $1,056 per year, or $3,168 over three years with the 299c value freeze.
At 4.47% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.
