A similar law is already taking effect in Philadelphia.

A bill was introduced in the Pennsylvania House of Representatives that would amend the Landlord and Tenant Act, requiring lead testing on rental properties built before 1978. The legislation would require the landlord to provide testing results to prospective tenants or tenants entering into a lease.

The City of Philadelphia already has a Rental Property Lead Certification Law, currently being phased in by zip code, requiring the testing and certification of rental properties as lead-safe. The law took effect in October of 2020 and is being phased in over the course of two years.
