Full Breakdown
Coweta County added detailed data center development standards to its M Industrial District permitted-use list at Section 191(12), reflecting the large-scale server facilities the county has begun seeing proposed along its industrial corridors. A data center or data center campus must occupy a minimum lot of 25 acres with at least 250 feet of public road frontage. Building height is capped at 60 feet, with an extra 10 feet allowed for parapets and rooftop mechanical equipment, for a hard ceiling of 70 feet. Setbacks are substantial: a 75-foot minimum front yard, 100-foot minimum side and rear yards, and a required 100-foot minimum separation between buildings on the same site.
Total lot coverage cannot exceed 80 percent, and the project must connect to public water and sewer rather than relying on wells or septic systems. Where a data center adjoins land zoned or used for residential purposes, Section 191(12)(e) requires a 300-foot buffer from the property line, with the first 100 feet left undisturbed and naturally vegetated (or replanted per Article 25 if it is sparsely vegetated) and the remaining 200 feet available for grading. Perimeter fencing must be decorative metal at least eight feet tall if it sits on the property line, and anti-climb features such as barbed or razor wire are prohibited on that fencing, though vinyl-coated chain-link with anti-climb features is allowed within the buffer if it is not visible from adjoining properties.
, with mailed notice to property owners within 1,000 feet at least 14 days in advance, newspaper advertising, and on-site signage. The identical development-standards package also applies to data centers approved as a conditional use in the LM Light Industrial District under Section 182(4).
Violations & Fines
Building a data center below the 25-acre minimum lot size, exceeding the 70-foot height ceiling, encroaching on the 75-foot front or 100-foot side/rear setbacks, or skipping the required 300-foot residential buffer violates Section 191(12). The Coweta County community development department can deny the site plan, withhold a land disturbance or building permit, and require redesign before construction proceeds; failing to hold the mandated pre-hearing community meeting can also delay or derail the rezoning petition itself.
