Before you sign
What to ask a San Francisco contractor first
- 01
Which material is planned — black iron, corrugated stainless tubing or another approved option — and does local code permit it?
- 02
Will a documented pressure test and inspection sign-off be provided before gas service is restored to the appliances?
- 03
Does the meter or regulator have capacity for the added appliance, or must the utility upgrade it first?
Before anyone touches a pipe
Verify the license. It takes two minutes.
- Who licenses the work: Contractors State License Board (CSLB).
- Who pulls the permit: San Francisco Department of Building Inspection (DBI) — the licensed contractor, never the homeowner.
- What to ask for: the license number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Gas Lines in San Francisco — common questions
I smell gas — what do I do first?
Leave the building. Do not switch lights or appliances on or off, do not use a phone inside, and do not look for the leak yourself. Call your gas utility's emergency line from outside — utilities respond to suspected leaks at no charge. Only after they have made it safe does a licensed plumber do the repair.
Can any plumber work on gas lines?
No. Gas work is separately licensed or endorsed in most states and always permitted. Confirm that the contractor holds the correct gas credential for your state before work starts, and that a permit is being pulled.
Do I need a permit to add a gas line for a range or grill?
In nearly all jurisdictions, yes. Gas piping is permitted and pressure-tested work. Unpermitted gas work is a safety issue, an insurance problem and a resale problem.
Do I need a permit for plumbing work in San Francisco?
Permits in San Francisco are issued by San Francisco Department of Building Inspection (DBI). As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
How should a gas lines quote be compared?
Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.
Who handles the permit for gas lines in California?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberCalifornia is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
