How Old Is Havana's Housing Stock?
With 73% 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
Heavily weighted toward older construction, Havana's housing stock carries a median build year of 1901. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Havana were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Havana: Remediation Cost in Perspective
Middle of the range — Havana homeowners face a remediation share that calls for real financial attention without reaching crisis territory.
Remediation costs are moderate relative to home values in Havana. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 45% below the North Dakota average.
Protecting Children from Lead in Havana
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 73% 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 Havana address.
