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.
