Cities in Kentucky currently have the power to govern within their boundaries without specific legislation authorizing each particular function. Before 1980, cities had to rely almost exclusively on the General Assembly to authorize various functions. However, with home rule cities can function in any way that does not directly conflict with state or federal law. Specific cases of such conflicts vary in terms of their standing, but cities generally have broad authority over their residents and can add to state and federal law; they may not subtract from it.
