Emergency Plumbing in San Francisco, California
San Francisco urgent plumbing decisions should separate a problem within the building from a street-system report. SF311 takes reports of flooding, leaks, backups, and sewer odors on the street; it is not a substitute for hiring a plumber for private fixtures or maintaining the lateral. Describe the exact location and whether the issue is active when calling.

Lateral investigation
SFPUC assigns owners maintenance of the entire sewer lateral, including clearing and jetting. Owners repair the upper section. If a plumber suspects a structural problem in the lower lateral, report it through 311 so SFPUC can evaluate rather than assuming all street-side work is privately authorized.
Hazard and condition reporting
Call 911 for a damaged hydrant gushing water or leaking heavily, as SF311 guidance directs. For unresolved private building plumbing or living-condition problems, DBI’s building-complaint process is a separate route; it investigates code conditions rather than providing emergency private plumbing service.
Issues to assess in San Francisco
- ✓Failure of private supply piping or fixtures
- ✓A blocked or defective sewer connection
- ✓A suspected public water-system leak
Do this right now
- ✓Isolate the private supply only if it is safe and accessible.
- ✓Describe the location and symptoms to the utility or a qualified plumber.
- ✓Confirm responsibility and any permit requirements before permanent repair.
General safety
- ✓Know where your main shut-off valve is and close it.

Use a complaint for code issues, not dispatch
For unresolved private plumbing conditions in San Francisco, DBI’s complaint process can investigate building-code concerns, but it does not dispatch an emergency household plumber. Arrange immediate private source control separately. Ask that plumber to record the failed component and remaining unsafe condition if you also need to pursue a building complaint.
