What is a legal nonconforming use?

A legal nonconforming use refers to a property use that was established prior to the implementation of a zoning ordinance that now prohibits that specific use. This situation often arises when zoning laws change, rendering certain land uses incompatible with the new regulations.

For example, if a restaurant was operating in an area that was later zoned for residential use, the restaurant can continue operating under the status of legal nonconforming use because it existed before the new zoning law took effect. Such uses can often remain in operation as long as they are maintained and do not cease for an extended period, regardless of changes in zoning.

In contrast, the other options do not accurately represent the definition of a legal nonconforming use. Compliance with current zoning laws would describe a legal conforming use, while a recent development would pertain to compliant uses developed under the current regulations. A temporary use implies a limited duration that does not connect with the concept of legal nonconformity, which deals with existing uses that predate current zoning.
