Housing Age Profile
The character of Upperco's housing stock is one of deep historical layering - a median build year of 1976 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Upperco were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Upperco
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Upperco is notably favorable - the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Upperco are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 26% above the Maryland average.
Upperco: Lead Risk & Vulnerable Populations
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Upperco have approached or crossed the regulatory action level on multiple occasions. Combined with 66% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
