Why the jurisdiction matters in a plumbing emergency
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.

Who do I call about a leak in the street or at the water meter?
Report water main breaks, leaking hydrants and other leaks outside the house to Baltimore City 311. Baltimore City DPW lists 443-263-2220 for water emergencies in its Baltimore County service area. Part of every residential service line is privately owned, and a leak on that part needs a plumber.
