Answer:
A nonconforming use.
Explanation:
The use of real property that is changed or prohibited by a subsequent zoning regulation is known as a nonconforming use.
This ultimately implies that, when a property is allowed to be used legally under the zoning regulations (ordinances) during the period it was established but no longer permitted for use, as a result of subsequent change made by a prior owner or in the zoning regulations (ordinances).
