The jurisdiction decides which number reports a street leak and which office issues the permit for plumbing work on your side. Baltimore City owns and runs the regional water system that also serves Baltimore County, but plumbing permits come from Baltimore City’s Building Official inside city limits and from the county outside them, which for Baltimore County homes means Permits, Approvals and Inspections.
10 ZIP codes on this list are split between jurisdictions, including 21206 (69% Baltimore City), 21207 (72% Baltimore County), 21209 (56% Baltimore County) and 21210 (84% Baltimore City). Check the jurisdiction column before you call the utility.

The same split applies to a leaking water line: which stretch of a Baltimore water service line the owner repairs depends on where the meter sits, and the permit office depends on the jurisdiction.
Both jurisdictions ban piping a sump pump into the sanitary sewer, each under its own code, and the penalties differ. The rules for each side of the city line are set out under sump pump repair in Baltimore City and County.
Sewer stoppages split the same way. City and County crews clear the public side of the lateral, and the owner arranges drain and sewer cleaning in Baltimore for a stoppage on the private side.
Burst, frozen, corroded and leaking water supply and drain pipes, repaired and pressure-tested.
Cracked, corroded and leaking cast iron drain stacks and basement drain lines, repaired by section or replaced.
Broken, root-filled and backed-up sewer laterals between the house and the public sewer.
Clogged sinks, tubs, toilets, floor drains and main building drains, cleared by a licensed, insured contractor who quotes upfront.
Leaking fittings, dripping relief valves and electric heaters that stopped making hot water.
Failed, nonstop-running and powerless sump pumps repaired or replaced.
Leaking, corroded and damaged natural gas piping after the BGE meter, pressure-tested and repaired by a licensed gas fitter.
Leaking, lead and galvanized service lines between the water meter and the house, repaired or replaced.
Worn-out galvanized, polybutylene and copper supply pipe inside the house, replaced.
20 of the 27 ZIP codes our network covers have most of their land in Baltimore City: 21201, 21202, 21205, 21206, 21210, 21211, 21212, 21213, 21214, 21215, 21216, 21217, 21218, 21223, 21224, 21226, 21229, 21230, 21231, 21239.
6 of the ZIP codes our network covers are mostly in Baltimore County: 21207, 21209, 21222, 21227, 21234, 21237. 21225 is mostly in Anne Arundel County. A Baltimore mailing address does not mean a home is inside city limits, which matters for plumbing permits and for which number reports a leak in the street.
Report water main breaks, leaking hydrants and other leaks outside the house to Baltimore City 311. Homes in the Baltimore County service area should follow DPW’s current guidance, and 311 can point you to the right line. Part of every residential service line is privately owned, and a leak on that part needs a plumber.
Call and give us your address, and we will connect you with a local plumber who works there.
