In which situation might a non-conforming structure be allowed to expand?

A non-conforming structure is one that does not conform to current zoning laws or regulations, usually because it was built before those laws were enacted. In scenarios where zoning laws are amended to allow for expansion, non-conforming structures may be granted the opportunity to increase in size or scope. This is because the amendment effectively changes the regulations that govern such structures, paving the way for them to expand legally.

For instance, if a municipality decides to relax certain zoning restrictions, it could grant additional rights to property owners, including those with non-conforming structures. This process often involves public hearings and a review of how the changes will affect the surrounding area, but it is a recognized means by which non-conforming structures can legally grow.

Other options do not provide valid circumstances for expansion. A structure's age or historic designation alone is not sufficient to justify expansion without changes in the law itself. Similarly, asserting that a non-conforming structure cannot be expanded under any circumstances overlooks the role of legislative changes in granting potential allowances.
