Louisville Zoning System
The Louisville zoning system includes 38 total zone classifications: 11 residential zones (R-1, R-2, R-3, R-4, R-5, and others) and 5 commercial zones (C-1, C-2, C-3, CN, and others), as well as 3 mixed-use zones (MU-1, MU-2, MU-3) and 3 industrial zones (M-1, M-2, M-3). Louisville Metro zoning is governed by the Louisville Metro Land Development Code (LDC), administered by Louisville Metro Department of Planning and Design Services. Louisville operates as Louisville-Jefferson County Metro Government — a consolidated city-county government formed in 2003 when the City of Louisville merged with Jefferson County. This consolidation means a single government entity administers zoning, permitting, and planning for what was previously two separate jurisdictions. The consolidated Louisville Metro Government is the 17th largest city-county government in the US by population. Kentucky has no statewide ADU law — all zoning authority rests with local governments under Kentucky Revised Statutes Chapter 100. The LDC governs development across the entire Jefferson County urban service area. The city maintains an interactive zoning map for property lookup.

Frequently Asked Questions
What is Louisville-Jefferson County Metro Government and how does it affect permitting?
Louisville-Jefferson County Metro Government (Louisville Metro) was formed in 2003 when voters approved the merger of the City of Louisville and Jefferson County into a single consolidated government. This means one planning and permitting department — Louisville Metro Planning and Design Services — handles zoning, permits, and development for the entire Jefferson County area. You don't have to navigate city vs. county differences. This is similar to Nashville-Davidson County's consolidated structure.
Can I build an ADU on my Louisville property?
Yes. Louisville Metro allows accessory dwelling units on single-family lots under the Land Development Code. Maximum size is typically 900 sqft for detached ADUs. Kentucky has no statewide ADU law — Louisville Metro's local LDC governs. No owner-occupancy requirement. You'll need a building permit from Louisville Metro Planning and Design Services. MSD sewer connection fees and LG&E electrical connection fees apply for independent utility service.
What is Old Louisville and do I need special permits there?
Old Louisville is the largest contiguous preserved Victorian neighborhood in the United States — approximately 45 blocks south of downtown with over 1,400 Victorian-era structures. If your property is in Old Louisville or another locally designated historic district, you may need a Certificate of Appropriateness from the Louisville Landmarks Commission for exterior modifications. This includes roofing, window replacement, additions, and exterior alterations. Contact Louisville Metro Planning and Design Services to check your property's historic status.
What are Louisville's STR (Airbnb) requirements?
Louisville Metro requires a Short-Term Rental License for rentals of 30 days or fewer. Annual fee is approximately $250. License number must appear in all booking platform listings. Occupancy limits (2 per bedroom), noise ordinance, and safety equipment requirements apply. Kentucky's 1% state transient room tax plus Louisville Metro's 8.5% lodging tax apply to STR income.
Is Louisville in a flood zone?
Many Louisville properties near the Ohio River, Beargrass Creek, and other waterways are in FEMA-designated Special Flood Hazard Areas. The 1937 Ohio River flood was catastrophic for Louisville — the Ohio reached 57 feet above flood stage. Check the FEMA Flood Map Service Center for your property's designation. MSD (Metropolitan Sewer District) administers stormwater and floodplain management for Louisville Metro. Properties in SFHA require flood insurance with federally-backed mortgages.
