Housing & Infrastructure in Grayson
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
Congress banned lead solder in residential plumbing in 1986, drawing a clear line in housing risk by era. Grayson's median build year of 2006 puts most of its residential stock on the newer side of that boundary - a profile that generally correlates with lower plumbing-sourced lead exposure across the city.
Most homes in Grayson were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Grayson Homeowners
Given current Grayson valuations, the remediation-to-property-value ratio is low - most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Grayson are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 78% above the Georgia average.
Lead Exposure Risk for Children in Grayson
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.
9% of housing in Grayson predates the federal action against lead solder - a contained share - and aggregate readings stay beneath the regulatory benchmark. Lead therefore sits in a quiet position on the local water-quality picture, with single-home draws as the standard tool for confirming any one address.

Historical NFIP Claim Context in Grayson
Historical NFIP data for Grayson contains 3 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $1,442. 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 <strong>$2,400</strong> 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.

What You Can Do in Grayson
- Test your water at home. City-level data shows averages - your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
