How Old Is Mexican Hat's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Mexican Hat, the median build year of 1994 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Mexican Hat were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Combined with 31% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
