How Old Is Manly's Housing Stock?
With 87% 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
Pre-1986 plumbing is not a rare legacy case in Manly — it's the dominant profile. The median build year of 1954 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Manly were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Manly: Remediation Cost in Perspective
The equity impact of remediation in Manly sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Manly. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 28% below the Iowa average.
Protecting Children from Lead in Manly
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.
Older interior plumbing shapes the local picture: 87% of Manly homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
