Housing Age Profile
A median build year of 1994 in Church Hill is characteristic of a mixed-era city where plumbing risk depends heavily on the specific property. Homes built before 1986 may have lead-soldered copper joints; those from before 1970 face the added possibility of lead service lines. The percentages above capture how much of the residential stock falls into each risk era.
Most homes in Church Hill were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Church Hill Homeowners
In Church Hill, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Church Hill are relatively low compared to home values. The $150–$600 estimated range is a small fraction of median property value. Home values are 10% below the Maryland average.
Lead Exposure Risk for Children in Church Hill
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: 40% of Church Hill 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.
