How Old Is Ohio City's Housing Stock?
With 52% 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.

Housing Age Profile
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1961 places Ohio City's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Ohio City were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Ohio City: Remediation Cost in Perspective
In Ohio City, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Ohio City are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 6% above the Colorado average.
Protecting Children from Lead in Ohio City
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.
Wherever 52% of local housing was built before solder rules changed — as is the case in Ohio City — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Ohio City
