List of cities in Kentucky

Before the enactment of House Bill 331, more than 400 classification-related laws affected public safety, alcohol beverage control, revenue options and others.

However, under state law, both major cities retained their pre-merger classification[5] before the new scheme took effect.

Because many provisions of state law applied only to cities of certain pre-2015 classes, House Bill 331 was explicitly written to address such issues.

In certain other areas that were more controversial, the pre-2015 status quo is being maintained through a registry of cities that were covered by prior laws.
