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

Section 4-1-120 sets the Property Development Standards for the A1 Rural Estate District, which the ordinance describes as preserving rural character through large-acreage tracts and sparse residential development. 6 caps Maximum Impervious Surface Coverage at fifteen percent of the lot, the same ceiling applied in the general Agricultural (A) district under Section 4-1-110, and tighter than the twenty-five percent allowed in the A2 Rural Estate District or the forty percent allowed in the R2 Two-Family district. The cap applies alongside the district's other dimensional standards: a two-acre minimum lot (one acre where served by public water and sewer), a 300-foot minimum lot width is not required here but a 150 to 200-foot minimum width at the building line depending on water/sewer service, and a 1,400-square-foot minimum house size.

Because the impervious limit is calculated across the whole lot rather than just the building footprint, driveways, parking pads, patios, decks, accessory buildings and any other hardened surface all count against the fifteen percent ceiling, which the Director's staff verifies at site plan and building permit review before issuing a permit for new construction or additions.
