Fayette County operates as a consolidated urban county government, meaning the city of Lexington and the county are a single jurisdiction. All building permits and zoning reviews are handled centrally by the Lexington-Fayette Urban County Government. There are no independent incorporated cities within the county that manage their own separate building departments.
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.
