Which statement is true regarding the legal standing of non-conforming structures?

The correct statement highlights that non-conforming structures can be protected under certain circumstances. A non-conforming structure typically refers to a building or property that was legally established but does not comply with current zoning codes or regulations. This situation often arises when zoning laws change after the structure has been built.

As long as the non-conforming structure was in compliance with the regulations that were in effect at the time of its construction, it is often allowed to remain in place. This principle protects property owners from losing their investment and provides stability within communities. Such structures are usually subject to specific restrictions regarding modifications or expansions, but they retain their legal status as long as they were lawful when established and continue to be used in accordance with those regulations.

The other statements do not accurately capture the nuances of non-conforming structures. Demolition of such a structure without a permit is typically not allowed because it often still holds legal status. Furthermore, labeling all non-conforming structures as illegal is misleading, as many are allowed to remain due to their prior compliance. Immediate compliance with current codes is not generally required; instead, non-conforming structures may be allowed to exist until they are substantially altered or rebuilt.
