Final answer:
Nonconforming use refers to property that doesn't comply with zoning requirements.
Step-by-step explanation:
Nonconforming use is a term used in reference to property that doesn't comply with zoning requirements. Zoning regulations are rules that restrict how a property can be used, such as the type of structures that can be built or the activities that can take place on the property. Nonconforming use occurs when a property is being used in a way that is not permitted by the current zoning regulations, but was allowed before the regulations were put in place. For example, a property that was originally zoned for residential use but is now being used for commercial purposes would be considered a nonconforming use.
