State guide
District of Columbia
In the District of Columbia, lead service line work is unusually centralized and well documented through DOEE and DC Water’s Lead Free DC pages. The official pages found say ownership and funding are split at the property line, but current District and DC Water programs can cover private-side lead replacement at no cost to enrolled property owners.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.

What to do next
- Check your address in DC Water’s service line inventory map before planning plumbing work; the replacement path depends on whether lead is on the public side, private side, or both.
- If your private side is lead, contact Lead Free DC before hiring a contractor, because current programs may replace it for free.
- If you are doing customer-initiated private-side work, confirm plumbing permit requirements with DOB before construction starts.
