Housing & Infrastructure in Cuba
With 93% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Cuba's median build year of 1903 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Cuba were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Cuba Homeowners
Because estimated remediation claims a substantial fraction of typical Cuba property equity, the household financial perspective here requires serious advance planning — the cost-to-value ratio is in the elevated tier and warrants structured preparation.
At 2.3% of home value, remediation costs in Cuba represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $800–$1,500. Home values here are 66% below the Kansas average.
Lead Exposure Risk for Children in Cuba
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 stock in Cuba represents 93% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

What You Can Do in Cuba
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 93% of homes built before 1986, lead solder is a real possibility.
