How Old Is San Miguel's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In San Miguel, the median build year of 1993 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in San Miguel were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

San Miguel: Remediation Cost in Perspective
Across San Miguel, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.

Protecting Children from Lead in San Miguel
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 34% 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 San Miguel address.
