Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Hacienda Heights's median build year of 1961 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 Hacienda Heights were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
