Summary
Hall County's Unified Development Code treats a data center as a Special Use that the Board of Commissioners must individually approve, and confines the use to the I-1 and I-2 industrial districts. Every other zoning classification in unincorporated Hall County, from AG-1 agricultural through H-B highway business, is marked not permitted for data centers on the Sec. 7.2.1 Allowed Use Table.
7.6.2. Data Center
A.Defined A facility dedicated to the housing of telecommunications exchanges, or computer or data processing, management, storage, equipment or systems. Data centers may also include accessory utility infrastructure such as air handler, power generator, water cooling and storage facilities, and similar infrastructure necessary to the operations at a data center.

Full Breakdown
Sec. A defines a data center as "a facility dedicated to the housing of telecommunications exchanges, or computer or data processing, management, storage, equipment or systems," and folds in the generators, air handlers and water-cooling equipment that support the servers as accessory infrastructure. The Sec. 1 Allowed Use Table lists "All data center" with an SU marking in only the I-1 and I-2 columns and a dash across the other thirteen districts. Under the Sec. 2 key, an SU marking "indicates a use may be permitted in the respective district only where approved by the County Board of Commissioners in accordance with Sec.
2," so a building permit alone cannot open a data center; it needs a Board vote after Planning Commission review. Sec. E requires the applicant to file a plat or site plan with the Planning and Zoning Department, pay the fees set for that section, and appear in person at the public hearing where the use is considered. 1 of Sec. 5-to-1 ratio. Because the UDC governs only unincorporated Hall County, this table has no bearing on a data center proposed inside Gainesville, Oakwood, Flowery Branch, Buford or Clermont, which are separate municipal jurisdictions with their own codes.
Violations & Fines
Building or operating a data center outside the I-1/I-2 districts, or without the Sec. 11.2 special use approval, is a UDC violation under Sec. 11.4.4: a misdemeanor punished per Sec. 1.50.020 with a fine up to $1,000, up to six months in jail (with at least 120 days probated), or both, and each day the violation continues is a separate offense. Sec. 11.4.3 also lets the county seek an injunction, mandamus or other action to abate the use, or notify utilities to withhold service until the property is brought into compliance.
