Housing Age Profile
For residents trying to assess tap water risk in Pleasant Hill, the median build year of 1957 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Pleasant Hill were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How much of a Pleasant Hill home's value does documented remediation represent? A small fraction — the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Pleasant Hill are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 2% above the Ohio average.
