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

1 of the Comprehensive Land Development Regulations governs any lot served by a private, non-public water supply system: it requires a minimum lot area of 43,560 square feet, a minimum lot width of 150 feet, and caps maximum lot coverage at 25 percent, and this applies regardless of the zoning district the parcel sits in. 2 sets minimum lot area, width and maximum coverage by zoning district and use, with most single-family districts (R-AG, R-1) also holding to 25 percent coverage. 3 uses a height-based sliding scale instead of a flat percentage: a one-story building needs 3,000 square feet of lot area per unit and may cover up to 40 percent of the lot; two- and three-story buildings hold the same 40 percent cap on 2,500 and 2,100 square feet per unit respectively; four- and five-story buildings drop to a 30 percent cap on 2,000 and 1,500 square feet per unit; and buildings of six stories or more drop further to a 25 percent cap on 1,000 to 1,250 square feet per unit.

2's public-water table took effect June 30, 2005. The county's planning and zoning department administers these standards through the building permit and site plan review process before a certificate of occupancy issues.
