How Old Is Ramona's Housing Stock?
With 74% 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
Because the majority of Ramona's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1954 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Ramona were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Ramona: Remediation Cost in Perspective
Viewed from a financial planning lens, Ramona sits in the moderate remediation-share tier — the equity impact of addressing documented issues is real, and deliberate preparation separates smooth outcomes from disruptive ones for most homeowners.
Remediation costs are moderate relative to home values in Ramona. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 38% below the South Dakota average.
Protecting Children from Lead in Ramona
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.
Routinely in Ramona, where 74% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
