Data center zoning regulations (Case No. 25-LDC-0014)
Louisville
Summary
Louisville is deciding where big data centers can go and how tightly to regulate them. The current draft allows large data centers only in M1 industrial zones with a conditional use permit, while an alternative would create a brand-new data center zoning district usable anywhere in the county. If the council passes nothing before the moratorium lapses, the old loose rules come back.

Impact analysis
Rules this strict could push data center investment to nearby communities like Elizabethtown or across the river, though no dollar figure was given.
Residents near sensitive uses gain separation protections; the whole community gets a say through the rezoning process.
Data center developers face rezoning requirements and a hard 500,000-square-foot cap with no relief available.

Planning and Zoning Committee — October 27, 2026
Louisville is deciding where big data centers can go and how tightly to regulate them. The current draft allows large data centers only in M1 industrial zones with a conditional use permit, while an alternative would create a brand-new data center zoning district usable anywhere in the county. If the council passes nothing before the moratorium lapses, the old loose rules come back.
Planning and Zoning Committee — October 20, 2026
Louisville is still deciding how strictly to regulate data centers — who pays for new power plants and water infrastructure, how waste heat and noise are handled, and what generators are allowed. The ordinance remains held in committee while members weigh cost-shifting to ratepayers against growth and tax revenue.
Planning and Zoning Committee — October 6, 2026
Louisville is writing its first real rules for data centers after a nearly million-square-foot facility slipped in before any regulation existed. Experts warned about low-frequency noise that can pierce walls and triggered a federal class action against Microsoft in Wisconsin, plus rising power demand and water use. The committee is weighing whether to apply uniform performance standards, keep the 500,000-square-foot ban, and require a new dedicated zoning district with rezoning and a conditional use permit.
Planning and Zoning Committee — September 15, 2026
New rules would cap data centers at 500,000 square feet, require conditional use permits for facilities 50,000 square feet or larger, mandate quarter-mile separations from homes, schools and hospitals, and protect ratepayers from infrastructure costs. The committee postponed action to allow more deliberation, and the existing million-square-foot facility on Camp Ground Road would be a non-conforming use that cannot expand.
Metro Council — September 10, 2026
Rules for the booming data center industry were formally introduced and sent to the Planning and Zoning Committee. Speakers want strong protections on electric rates, water use, noise, and renewable energy.
Planning Commission — August 10, 2026
Louisville is writing new zoning rules for data centers after a hyperscale facility was approved on Campground Road. Residents want a moratorium, stricter size limits, mandatory closed-loop cooling, noise caps, and ratepayer protections — and say the draft's 'encouraged' language isn't enforceable.
Planning Commission — June 18, 2026
The commission is gearing up for what could be a very rowdy, very long public process on new data center zoning rules. Three evening hearings are set for late July and August, capped at two minutes per speaker, with a decision on August 20.
Planning and Zoning Committee — June 16, 2026
Louisville is racing to regulate data centers after a project blindsided District 1. Draft rules would cap hyperscale facilities at 500,000 square feet, restrict them to industrial zones, add noise and ratepayer protections, and require prevailing wage. The formal moratorium was tabled again, with leaders relying on informal coordination instead.
