How Old Is Bonney Lake's Housing Stock?
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
Over the decades, Bonney Lake accumulated housing from multiple construction periods. The median build year of 1993 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.
Most homes in Bonney Lake were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Bonney Lake: Remediation Cost in Perspective
How much of a Bonney Lake home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.
Remediation costs in Bonney Lake are relatively low compared to home values. The $1,100–$2,600 estimated range is a small fraction of median property value. Home values are 24% above the Washington average.
Protecting Children from Lead in Bonney Lake
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 31% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Bonney Lake.

Historical Flood-Claim Evidence for Bonney Lake
Historical NFIP data for Bonney Lake contains 18 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,319. 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>$1,700</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.
