Johns Creek's single-family residential districts (R-1 through R-6) do not set a single percentage lot-coverage cap in the Zoning Ordinance; buildable area is shaped by minimum lot size, setbacks, and stream-buffer/impervious rules. Some higher-density and commercial districts do cap coverage - 50% in TR townhouse, 40-80% in others, and 75% impervious in MIX.
Unlike many cities, Johns Creek's standard single-family districts (R-1, R-2, R-3, R-4, R-5, R-6) are not governed by a flat maximum lot-coverage or maximum-impervious percentage in the Zoning Ordinance's development standards. Instead, how much of a residential lot can be built on is controlled indirectly through the minimum lot area (for example, two acres in R-1, one acre in R-2, 18,000 sq ft in R-3, 9,000 sq ft in R-4 and R-6, 7,500 sq ft in R-5), the required front, side, and rear setbacks, and environmental constraints such as the 50-foot undisturbed stream buffer, the 25-foot impervious setback from state waters, and the city's stormwater/tree-preservation regulations. Some higher-density and nonresidential districts DO impose explicit caps: the TR townhouse district limits the footprint of all buildings and parking to 50 percent of total land area (Section 7.2.3.K); other districts in the code cap lot coverage at 40 percent or 70 percent; the Town Center districts list 70-80 percent coverage; and the MIX mixed-use district caps maximum impervious area at 75 percent of the development. Because coverage limits are district-specific and several residential districts rely on setbacks rather than a percentage, owners should confirm their parcel's zoning, lot area, buffers, and any rezoning conditions with the Community Development Department before designing additions, pools, or driveways. Stormwater rules in Code Chapters 109 and 113 may also limit impervious surface on a given lot.
Exceeding an applicable district coverage or impervious cap, or building over a stream buffer or impervious setback without Board of Zoning Appeals approval, violates the code and can result in stop-work orders, citation, and required removal of excess impervious area.
