Which term describes a property use that does not conform to local land use controls?

The term that describes a property use that does not conform to local land use controls is called a non-conforming use. This concept refers to situations where a property or its use was established legally before the current zoning regulations were implemented, but it no longer aligns with the new regulations.

For example, if a factory was built in an area that later became zoned for residential use, the factory would represent a non-conforming use. While it is allowed to continue operation under the terms of "grandfathering," any changes, expansions, or major renovations might be limited or require special variances to comply with the newer zoning laws.

A permitted use refers to activities or developments that are explicitly allowed under zoning laws, while a conforming use describes properties and activities that fully comply with the zoning regulations. An illegal use, on the other hand, is one that contradicts zoning laws without any legal basis or grandfathering clause, often leading to enforcement action against it.
