Your water utility in San Francisco
San Francisco Public Utilities Commission (SFPUC)
Worth knowing for two reasons. If you can't find or operate your main shutoff, the utility can shut supply at the street — their emergency number is on your water bill. And if a backup coincides with heavy rain or is affecting neighbours too, it may be a municipal issue, in which case their crew costs you nothing.
Verifying a plumber's license in California
California Contractors State License Board (CSLB)
California requires a C-36 Plumbing contractor license for any plumbing job over $500 including materials. The CSLB's free lookup shows license status, bond, and workers' compensation coverage. Verify the C-36 specifically — a general B license is not the same thing, and California has a high volume of unlicensed operators.

A legitimate plumber gives you their license number without hesitation. Confirm it's active, covers the scope of the job, and matches the company name on your invoice.
San Francisco housing stock and pipe materials
Among the oldest housing stocks in the western US. Pre-1940 buildings commonly retain galvanized supply and cast iron drains, and many are multi-unit.
What commonly fails in San Francisco
- Dense attached and multi-unit housing means one leak routinely affects neighbouring units and creates immediate liability. Act fast and document everything.
- Steep terrain produces long, deep sewer laterals -- get camera footage before any excavation quote.
- In flats and condos, shared lines are usually the building's responsibility. Contact management at the same time you call a plumber.
Before a plumber reaches you in San Francisco
- Shut off the water at the main, or the fixture's own valve if the leak is isolated.
- Open the lowest faucets to drain remaining pressure away from the break.
- Cut power to affected areas at the breaker — only if you can reach the panel without standing in water.
- Photograph and video everything before cleaning up. This is your insurance record.
- If sewage is involved, stop using water everywhere in the house and keep people and pets clear.
