Data centers may operate only in locations permitted under the amended Union County Development Ordinance.

Data centers must comply with supplemental requirements added specifically for the use.

Office uses are permitted as of right in the O, B-2, B-3, B-4, HC, LI, and HI districts, which may facilitate data-center development when the facility is classified as an office use. Office uses are permitted

Warehouse uses are permitted as of right in the LI and HI districts, potentially accommodating data centers classified as warehouse or storage facilities. Warehouse uses

Office, commercial, and industrial districts generally have no minimum lot-area requirement. LI and HI districts allow buildings up to 100 feet high, with 50-foot street and rear setbacks and a 20-foot side setback, providing comparatively flexible site and building standards for large facilities. No minimum lot area

The ordinance requires development infrastructure, including streets, water and wastewater systems, stormwater improvements, utilities, streetlights, and street trees, and requires connections to public water or sewer when lines are within specified distances. This provides a regulatory framework for extending infrastructure to serve a qualifying facility, although developers are responsible for construction and installation. Developers are responsible for the construction and installation

Applicants may obtain alternative parking ratios by submitting a parking study showing that standard ratios do not reflect expected demand, provided the approving authority finds the alternative supported by competent data and unlikely to harm traffic safety or surrounding welfare. Alternative compliance parking ratios

Shared parking may be approved for mixed-use projects and multiple nonresidential uses with different demand periods, allowing required parking to be calculated from overlapping peak demand rather than adding each use's full requirement. Residential and accessible parking may not be shared. Shared parking is encouraged

Applicants may seek alternative loading ratios through a loading study when standard loading requirements do not reflect actual demand, subject to a finding that the alternative will not adversely affect circulation, safety, or surrounding welfare. Alternative compliance loading ratios

The MPD district allows the Board of Commissioners to establish project-specific uses, residential densities, nonresidential intensities, lot standards, and deviations from otherwise applicable development standards, enabling large or complex projects to be approved under customized standards. Use regulations and lot and building standards

An approved site-specific development plan may create a zoning vested right allowing the owner to undertake and complete the approved development despite later zoning actions that would otherwise change, impair, prevent, diminish, or delay it. The vested right lasts two years, with possible county extensions up to a maximum total of five years. A vested right confers upon the property owner

Lawfully established nonconforming uses and structures may continue. Nonconforming structures may be altered or expanded when the work complies with applicable standards and does not increase the extent of nonconformity; nonconforming uses may be changed to uses allowed in the district. Nonconforming structures may remain

Private electric-vehicle charging stations are permitted as accessory uses in all zoning districts, public charging stations are permitted as accessory uses to allowed nonresidential uses, and geothermal heat-exchange systems are permitted as accessory uses in all districts. Accessory solar systems are also authorized subject to building, electrical, setback, height, and coverage rules. Private electric-vehicle charging stations

Alternative landscape, screening, and lighting compliance plans may be approved when strict compliance is impractical because of site limitations, topography, soils, existing structures or utilities, safety concerns, or when the alternative provides an equal or better result. Alternative compliance landscape plans
