What is meant by "Non-Conforming Use" in zoning regulations?

In zoning regulations, "Non-Conforming Use" refers to a land use that does not comply with current regulations but was legally established under previous zoning laws. Such uses are often allowed to continue existing even if they do not align with new ordinances because they were in place before those regulations changed. It is important for municipalities to allow these uses to continue to avoid creating undue hardship on property owners who made investments based on earlier zoning standards.

This concept acknowledges that although a property may not conform to the current zoning regulations, it had a legitimate purpose and operation when established, and thus, it is often permitted under specific conditions. Non-conforming uses may be subject to regulations about expansions or alterations to minimize conflicts with the new zoning framework. The other options refer to uses that either comply with current regulations or are subject to special permits or time restrictions, which do not align with the definition of non-conforming uses.
