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

Table 2-4, the Development Standards Table in Article II of the UDC, runs a "Lot Coverage (maximum, percent)" column alongside lot size, setbacks, height, density and public sewer requirements for every zoning district. Section 2.04.03.A explains how to read it: "a dash '—' indicates no development standard applies for the specified category." Scanning the table district by district, PCFD, A-1, R-A, R-1, R-2, R-3, R-4, R/TZ, C-1, C-2, C-3, I-1 and I-2 all show that dash in the lot-coverage column, so none of them face a countywide percentage cap on building or impervious footprint; those districts are instead controlled through their setback, height and density rows.

The Commercial-Residential (C-R) district is the lone exception. Its row caps lot coverage at 30 percent, specifically defined by a footnote as the total ground floor area of a building, alongside a density rule requiring the first unit to be at least 10,000 square feet and each additional unit at least 4,000 square feet, plus a requirement that 20 percent of the development be set aside as green space. Because C-R exists to host quadraplexes and multifamily apartment buildings served by public sewer with limited ground-floor commercial uses, the 30 percent ceiling keeps those denser residential-commercial sites from being built out edge to edge.

Anyone developing outside C-R should not expect a coverage percentage in the ordinance itself; the county's separate setback, buffer and floodplain sections do the practical work of limiting how much of a residential or agricultural lot can be built on.
