What does nonconforming use refer to?

Nonconforming use refers to a situation where a property is being used in a way that does not conform to current zoning laws but is permitted to continue existing. This type of use is typically allowed because the property may have been established before the zoning laws were enacted or modified. As such, while the current regulations might prohibit the specific use of the property, the local government often permits it to remain in operation to avoid what could be significant disruption or economic loss to the property owner or the community.

The other options illustrate different concepts: compliance with zoning laws describes a conforming use, temporary uses are usually designated under specific permits, and illegal uses would not be sanctioned by any zoning regulation. Therefore, the definition of nonconforming use aligns succinctly with a use of property that, while it does not meet current zoning standards, is nonetheless allowed to persist.
