Louisville Building Permits
Louisville Metro's Department of Codes and Regulations, through its Office of Construction Review at 444 South Fifth Street, permits and inspects construction across all of Jefferson County; city and county have been one jurisdiction since the 2003 merger. It enforces the Kentucky Building Code and Kentucky Residential Code, which apply statewide as both the minimum and the maximum. Some small cities inside the Metro boundary issue their own sign permits by agreement, so check the city first.
