Pennsylvania Statutes Title 21 P.S. Deeds and Mortgages § 613.1. Agreements of sale

(a) Every owner shall insert in every agreement for the sale of property a provision showing the zoning classification of such property, and stating whether the present use of the property is in compliance with or in violation of zoning laws and ordinances, and every owner shall insert in every agreement for the sale of property a provision disclosing whether there exists any notice of an uncorrected violation of the housing, building, safety or fire ordinances.

(b) If any owner fails to include any provision required by this act in an agreement for the sale of property, then in any action, at law or in equity, instituted by a purchaser against an owner, it shall be conclusively presumed that the owner at the time of the signing of such agreement, represented and warranted to the purchaser that such property was being used in compliance with the then existing zoning laws and ordinances, and that there was no uncorrected violation of the housing, building, safety or fire ordinances.
