How Old Is Humboldt's Housing Stock?

Copper
Likely Pipe Material

With 60% 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 1988 places Humboldt'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.

Pre-1970 (Lead Pipes Risk)
Pre-1970 (11%) 1970–1986 (49%) Post-1986 (40%)

Over half of homes in Humboldt were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Humboldt: Remediation Cost in Perspective

When estimated remediation is placed alongside median property values in Humboldt, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.

Median Home Value
$268,300
Est. Remediation
$400
Remediation as % of home value 0.1%

Remediation costs in Humboldt are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 12% below the Arizona average.

Protecting Children from Lead in Humboldt

60%
Homes Built Before 1986

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.

Locally, 60% of Humboldt homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.
