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

Table 2-4 of the Unified Development Code, the county's Development Standards Table, runs a "Principal Building Height (maximum)" column next to lot size, setbacks and density for every zoning district. For R-1, the county's standard single-family district built on 22,000-square-foot lots, that column reads simply "3 stories," the same limit set for the R-A, R-2 and R-3 residential districts. R-4, the Manufactured Housing Development District, is governed instead by construction-standard language requiring conformance with the National Manufactured Home Construction and Safety Standards rather than a stories figure.

The R/TZ Residential Townhouse/Zero Lot Line District uses a different formula, capping principal buildings at three stories or 35 feet, and separately requires that no townhouse building sit closer than 25 feet to any R/TZ zone boundary. Height in the Agricultural (A-1) district works differently still: it lists a numeric 50-foot cap, but a footnote in Table 2-4 exempts silos, granaries, windmills, barns and other structures essential to agricultural operations, along with church spires, water towers, chimneys and flagpoles, from that maximum entirely. Commercial and office districts run higher: C-1 and C-3 allow six stories, C-2 caps out at three stories, and both industrial districts, I-1 and I-2, allow six stories.

Any building proposed above these caps needs a variance from the Board of Appeals under the UDC's Article IX variance procedures rather than an administrative sign-off, since Table 2-4 compliance is a baseline requirement under Section 2.04.01.B for every lot and building in the zones set out in Section 2.02.00.
