In a recently published opinion, the Pennsylvania Commonwealth Court in Shyam Ventures v. Zoning Hearing Board of the Borough of Castle Shannon, 2024 Pa. Commw. LEXIS 76 (Pa. Cmwlth. Mar. 7, 2024), set clear limits on the expansion of a legal nonconforming use and when such an expansion may be considered an entirely new use altogether.

The case concerns a property in the borough of Castle Shannon that operated a U-Haul vehicle rental business and a coin-operated laundromat since at least 2008, the opinion said.
