How Old Is Bonner's Housing Stock?
With 45% 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
The story of Bonner's housing stock is one of layered development - neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1981 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards - creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Bonner were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Bonner: Remediation Cost in Perspective
The household financial picture for Bonner homeowners is proportionally favorable - addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Bonner 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 57% above the Montana average.
Protecting Children from Lead in Bonner
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 45% 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 Bonner address.

Historical Flood-Claim Evidence for Bonner
Historical NFIP data for Bonner contains 2 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $1,872. Among ZIP codes with claim records, 100% 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.
