Troup County, GA Building Setbacks & Zoning: Structure Height Limits (2026)

Sec. 4.1's Space Dimensions Table sets the maximum building height for most of unincorporated Troup County, including the AG, agricultural district, AG-R, SU-R, LR, LC, LI, and HI columns, at 40 feet; only UR-VL, the urban village high-density mixed-use district, is allowed to build to 85 feet. That 40-foot cap governs the typical rural home, barn, or accessory building in the county's dominant agricultural and residential districts. Sec. 4.4, Building height exceptions, then carves out a category of features the height limit does not reach at all: spires, belfries, cupolas, domes, chimneys, mechanical and electrical equipment and its screening, smokestacks, derricks, conveyors, flagpoles, and aerials.

Rather than exempting those elements outright, the ordinance lets them rise to the district's maximum height plus an additional 15 percent, so on an AG lot with a 40-foot cap a qualifying chimney or flagpole can reach 46 feet before it needs relief. Everything else, including the main roofline and any occupied floor, stays inside the district's flat 40-foot ceiling in Sec. 4.1. Height is calculated off the same Space Dimensions Table that also governs setbacks and lot width, so a proposal that raises the roofline typically triggers the same Community Development Director review used for setback compliance, and any project that cannot meet the 40-foot cap or the 15-percent exception must go to the Board of Zoning Appeals and Planning Commission for a variance rather than proceed on a building permit alone.
