Philadelphia Lead Certification for Multifamily/Duplex Properties

[Jibu V.]

If you have a tenant with a child under 6 living in a rental property in Philadelphia, PA, you need to have a lead safe certificate (lead wipe test results). This applies to all properties built prior to 1978. 

If only one unit of a multifamily/duplex property will have a child occupant under 6 years old, are we required to get a lead safe/free certification for both units or for only the unit(s) that falls within the lead certification requirements? 

I read the Philadelphia guidance and must have overlooked this scenario.
