Union City stretches along the I-85 corridor in south Fulton County, just southwest of Hartsfield-Jackson, and much of its workforce is tied to the airport, warehousing, and logistics jobs that cluster around it. With about 27,728 residents, it is one of south Fulton's larger cities, and its housing is priced for working families: the median home is worth about $245,600, roughly 46% below the Fulton County median of $458,800. That is the core tension of being an affordable city inside an expensive county. Across Fulton County, home values range from about $286,572 at the 25th percentile to $735,809 at the 75th, so the typical Union City house is worth less than the county's 25th percentile home, and valuation models tuned to Fulton's broader market tend to run high at the affordable end of the range. The burden lands hard here. Fulton's effective rate is about 1.42%, and with a median household income of $49,549, the typical Union City homeowner already gives up about 4% of household income to property taxes, an unusually heavy share. An assessment even 10% too high deepens that strain, and it repeats, because this year's value becomes the starting point for next year's. It costs nothing to set your notice against actual sales on your street. If the number does not hold up, Georgia allows 45 days from the date printed on the assessment notice to file an appeal, and missing the window means living with the value for another year.
Union City Appeal Quick Facts
The median home in Union City is valued at $245,600, and the typical homeowner pays about $1,996 per year in property tax (Census ACS 2024), based on Fulton County's 3.553% combined millage applied to 40% of fair market value after exemptions. That means the typical Union City homeowner spends 4.03% of household income on property taxes alone. Even though Union City home values fall below the Fulton County average, the tax burden here is significant relative to household income. A lower home value does not mean your assessment is automatically correct. Overassessments happen at every price point, and correcting one can meaningfully reduce your annual bill. At $245,600, Union City home values are 46% below the Fulton County median, 44% above Georgia's statewide median of $170,200, 22% below the national median of $318,000.
Check If Your Union City Home Is Overassessed
Johns Creek leads Fulton County in home values, but your individual assessment could still be too high regardless of where Union City falls in the county ranking.
With a population of 27,728, Union City 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.
