I'm not sure what type of inspection you are inquiring about especially since this property is showing as off the market.. I will answer assuming that you mean a home inspection. We as agents have no definite way of know when or if a home inspection was performed on a property unless we are dirctly involved in the transaction. However, this duplex last changed owners in 1979 almost 2 decades prior to the popularity of the Home Inspection Contingency in home sales. If you are speaking of some type of L& I Inspection, you would have to contact the City of Philadelphia and see if they can answer that for you.
