What does police power non-conforming use refer to?

Police power non-conforming use specifically refers to pre-existing uses that do not conform to current zoning regulations. When a property owner has a use that was permissible under previous zoning laws but is now restricted or prohibited under new regulations, that use is considered non-conforming. The principle behind this concept is to allow existing businesses or land uses to continue operating despite changes in zoning laws, thereby protecting property rights and ensuring that owners are not unduly penalized for changes in regulations that occur after they have established their use.

This concept is important in urban planning and zoning as it provides a legal avenue for existing properties to continue their operations while new developments or zoning adjustments take place, which could potentially lead to a more organized and controlled development of land. It acknowledges the reality that, over time, land use plans may need to adapt, but existing rights to use the property should be considered and respected within the framework of changing regulations.
