Troup County, GA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Sec. 4.1 of the Troup County Unified Development Ordinance, Appendix B, carries two coverage rows in its Space Dimensions Table: Maximum Building Coverage (percent of individual lot area) and Maximum Impervious Coverage. For the AG, AG-R, SU-R, LR, and SU-VL columns, both rows read "N/A", meaning the UDO does not cap how much of an unincorporated agricultural or rural-residential lot can be covered by buildings or by impervious surface such as driveways, parking, and patios. The cap only starts at UR-VL, the urban village district (60 percent building coverage, 70 percent impervious), and rises through LC and HC and the industrial districts LI and HI (70 percent building, 80 percent impervious).

Because most unincorporated Troup County land defaults to AG under Sec. 1.5(2)(d) when it is not otherwise classified, the practical limit on a typical rural parcel is the district's yard setbacks in the same table rather than a coverage ratio: the 50-foot side and rear and 100-to-145-foot front setbacks in Sec. 4.1 do the work a coverage percentage would elsewhere. Accessory structures still face their own lot-coverage cap under Sec. 4.7(1)(c)(iii): where they do not count as floor area, they carry no limit at all on agricultural and industrial parcels, and a 25 percent cap on every other use.

Applicants building on AG or AG-R land who want to confirm how much of a lot they can cover should request a written zoning verification from the Community Development Director rather than assume the higher-density district percentages apply.
