Housing & Infrastructure in Cypress
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
Whether your home in Cypress was built before or after 1986 matters more than the citywide median of 2013, because the 1986 federal lead restrictions cover plumbing installed after that point.
Most homes in Cypress were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Cypress Homeowners
Measured against the median home value, the estimated cost of fixing the issues flagged for Cypress lands in the lowest of the three tiers this page uses.

Lead Exposure Risk for Children in Cypress
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
What does the lead data say about a home in Cypress? Only part of the story. The average of 90th-percentile lead results across the city's ZIP codes is at least 0.010 mg/L, and roughly 11% of dwellings date from the pre-1986 period. Lead usually enters drinking water from a building's own service line and plumbing, so results at any one faucet can be higher or lower than the area average.
1 ZIP code (33% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Historical NFIP Claim Context in Cypress
Historical NFIP data for Cypress contains 3,219 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $89,200. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $950 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
