Zoning Report
Louisville, KY Zoning
Louisville Metro regulates land use through a Land Development Code tied to Plan 2040. Its zoning system combines zoning districts with form districts, meaning a property's allowed use comes from the zoning district while many siting and design rules come from the form district. The current code includes chapters for zoning districts, special districts, form districts, parking, landscaping, signs, subdivision, and development review procedures. Some suburban cities in Jefferson County use their own adopted versions of the code, so the exact applicable rules depend on jurisdiction as well as parcel location.
