What is a code enforcement case?
A code enforcement case is opened when a Metro inspector finds a property out of compliance with a local property maintenance ordinance — things like exterior storage, uncut grass, or exterior structural upkeep.
Louisville Metro Codes & Regulations opens and manages the case. No board or hearing is required to open one.
The property owner is notified and given a chance to correct the violation. An inspector re-checks the property; the case closes once the violation is corrected and confirmed.
An open case is not a citation or a fine by itself, and it does not mean a court has found the property owner at fault. It records that a violation was observed and is being tracked to correction.
