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
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.
