Legal nonconforming use

A use that may lawfully continue despite not meeting current zoning requirements, subject to jurisdiction-specific rules and evidence.

Why it matters

The status is not established by age alone. Discontinuance, expansion, alteration, or casualty can affect continuation rights and require legal or municipal confirmation.

In practice

A project example

An existing use is allowed to remain, but a proposed expansion requires separate zoning review.
