How Old Is Toledo's Housing Stock?
With 78% 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
Viewed through the lens of construction era, Toledo is predominantly an older city — a median build year of 1967 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Toledo were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Toledo: Remediation Cost in Perspective
When estimated remediation is placed alongside median property values in Toledo, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Toledo are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 12% below the Oregon average.
Protecting Children from Lead in Toledo
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.
If 78% of the Toledo inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Climate-Related Water Risk for Toledo
FEMA data shows 100% of Toledo's ZIP codes mapped into designated flood zones, paired with an NFIP record of 8 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Toledo has a moderate flood history with 8 FEMA claims averaging $10,283 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$1,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
