How Old Is Philadelphia's Housing Stock?
With 62% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Philadelphia's median build year of 1970 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Philadelphia were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Philadelphia: Remediation Cost in Perspective
Equity impact data for Philadelphia lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Philadelphia are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 26% below the Missouri average.
Protecting Children from Lead in Philadelphia
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
When older housing represents 62% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Philadelphia address.
