Which term is used for properties that do not conform to current zoning laws but were legal before the changes?

The term "nonconforming use" refers to properties that were legally established in accordance with zoning laws at the time of their creation but no longer comply with current zoning regulations due to changes in those laws. This situation often arises when local governments modify zoning ordinances to reflect new planning objectives, such as increased density or different land use priorities.

Properties designated as nonconforming uses are allowed to continue operating even though they do not meet the new standards, as a means to prevent the disruption of established businesses or living conditions. Nonconforming use typically allows for the continued use of the property in its original capacity, though there might be restrictions on expansion or changes that could further violate current zoning laws.

Understanding nonconforming use is crucial for real estate professionals, as it informs how properties may be valued, developed, or revitalized, considering their legal standing under local zoning regulations.
