ARTICLE I · COUNTY BASELINE
CODES & LOCAL AUTHORITY
FIPS 21111
Article I · County Baseline

The county inherits from the state. And adds local rules.

2018 International Building Code and 2018 International Residential Code with local amendments.

Jefferson County operates under a consolidated city-county government known as Louisville Metro. The Department of Codes and Regulations manages building permits for the entire county, including the central city and all incorporated suburban cities. Development is subject to the Land Development Code which governs zoning, floodplains, and environmental overlays.

The county enforces a strict Land Development Code that requires specific landscape and tree canopy preservation plans for most new construction and major renovations.

How this fits with the state

The state authority here is Kentucky Department of Housing, Buildings and Construction; local governments. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
