Lilburn grew up along the old Lawrenceville Highway corridor in southwestern Gwinnett County, and today it is one of the county's most diverse cities, home to a revived Old Town district and to the BAPS Shri Swaminarayan Mandir, one of the largest Hindu temples in the country. Its housing remains comparatively attainable for Gwinnett: the median home is worth about $329,700, roughly 13% under the county median of $380,900, in a county where the middle band of home values spans about $289,831 to $487,646. The tax math is less forgiving than the sticker price. Median household income in Lilburn is about $63,581, and the typical homeowner here loses about 5.8% of household income to property taxes each year, one of the steeper income shares in the metro, even though Gwinnett County's effective tax rate is an ordinary 1.4% of home value. That combination, moderate incomes carrying full-price assessments, is exactly where an inflated valuation drains a family budget every single year. Lilburn's housing stock runs from 1970s ranches and split-levels to newer infill, and county models frequently miss the condition gap between them, valuing dated interiors as if they had been updated last spring. Pull your assessment notice and set its figure against recent sales in your own subdivision, not the county at large. Georgia homeowners get 45 days from the date printed on the assessment notice to challenge the value, and there is no second chance until the next notice arrives.

Lilburn Appeal Quick Facts

Is your Lilburn property tax assessment too high?

The median home in Lilburn is valued at $329,700, and the typical homeowner pays about $3,686 per year in property tax (Census ACS 2024), based on Gwinnett County's 3.506% combined millage applied to 40% of fair market value after exemptions. That means the typical Lilburn homeowner spends 5.8% of household income on property taxes alone. Even though Lilburn home values fall below the Gwinnett 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 $329,700, Lilburn home values are 13% below the Gwinnett County median, 93% above Georgia's statewide median of $170,200, 3% above the national median of $318,000.

Peachtree Corners leads Gwinnett County with a median home value of $484,700, compared to Lilburn's $329,700. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.

In Lilburn, there are typically enough recent sales to build a strong case. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.
Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment -- your taxes will not increase as a result of appealing.
