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

Coweta County's Village Center Ordinance and Design Guidelines (Article 13) regulate how much of a residential lot can be covered by buildings, driveways, patios, and other impervious surfaces, scaling the limit to the size of the lot rather than applying one flat number countywide. Section 135, Standards for authorized principal uses, ties the impervious surface ratio to the three lot-size categories defined in Table 6: large lots exceeding 12,000 square feet are capped at 35 percent impervious coverage, mid-size lots of 9,001 to 12,000 square feet are capped at 40 percent, and small lots of 6,000 to 9,000 square feet are capped at 45 percent.

The graduated scale lets smaller, more urban lots in the Village Center carry proportionally more hardscape, driveways, walkways, and porches, while larger lots preserve more pervious yard area for stormwater absorption. These caps apply specifically to single-family, detached residential development inside the mapped Village Center district under Figures 1 and 2 of the design guidelines; other Village Center housing types carry their own separate ratios (zero-lot-line homes are capped at 45 percent, attached single-family at 65 percent, and multifamily buildings at 65 percent), and land outside the Village Center boundary is instead governed by the separate dimensional table in Article 23.

A site plan submitted for a building permit in the Village Center must demonstrate compliance with the applicable ratio before the community development department will approve construction.
