In Springfield Twp. v. Kim, 792 A.2d 717 (Pa. Cmwlth. 2002), the Court explained: One who undertakes to make use of real estate for commercial purposes without inquiring as to whether the use is permitted by the municipality's zoning ordinance, does so at his own peril. The purchaser's duty to inquire is not limited to whether a particular use is permitted but, by implication, must also encompass an inquiry into the limitations placed on the manner in which the property may be used, e.g., a recreational vehicle park was a permitted use but not for permanent residences. Id. at 722.
