Louisville Metro Zoning & Land Use Guide
Key Zoning Facts
Louisville Metro Zoning Overview
Louisville Metro, formed by the 2003 merger of the City of Louisville and Jefferson County, is Kentucky's largest city and the state's primary economic hub. The merged government administers zoning across the entire county, encompassing the dense urban core along the Ohio River, established suburban neighborhoods, and rural areas in the eastern and southern portions of Jefferson County. Louisville's Land Development Code (LDC) provides a comprehensive framework for managing this diverse landscape.
The city's zoning reflects Louisville's history as a major river port and industrial center, with significant areas devoted to logistics, manufacturing, and warehousing along the Ohio River and railroad corridors. The Bourbon District, NuLu arts district, and other revitalized areas demonstrate the city's approach to adaptive reuse and mixed-use development in formerly industrial neighborhoods.
Key Zoning Districts
Louisville Metro's Land Development Code includes residential districts from R-1 (estate lots) through R-8 (high-density apartments), commercial districts (C-1 through C-3), industrial zones (M-1 through M-3), and specialized districts for downtown, mixed-use, and planned development. Form districts overlay traditional zoning to regulate building form and site design in different areas of the metro.
ADU Regulations
Louisville Metro permits accessory dwelling units in certain residential zones with local restrictions on size, height, setbacks, and owner-occupancy. Kentucky has no statewide ADU mandate, so Louisville's Land Development Code governs all aspects of ADU development within the metro area. The city has expanded ADU opportunities in recent years as part of housing affordability efforts.
Development Process
Development in Louisville Metro begins with a pre-application conference at Planning & Design Services. Projects may require plan review by the Planning Commission and approval by the Metro Council depending on complexity. The Kentucky Building Code (2018 IBC) is enforced by Louisville Metro's Department of Codes and Regulations.
