68 Pa.C.S. § 4106

A zoning, subdivision, building code or other real estate tax or use law, ordinance or regulation may not prohibit the cooperative form of ownership or impose any requirement upon a cooperative which it would not impose upon a physically identical development under a different form of ownership. Otherwise, no provision of this subpart invalidates or modifies any provision of any zoning, subdivision, building code or other real estate tax or use law, ordinance or regulation except as is otherwise provided in section 4321(f) (relating to limited equity cooperatives).
