Before you sign

What to ask a San Francisco contractor first

  1. 01

    How does the lease split responsibility between landlord and tenant for this repair, as that determines who authorizes the work?

  2. 02

    Which occupancy class and code chapter govern this building, since commercial fixture counts and venting rules differ from residential work?

  3. 03

    Can the work proceed outside trading hours, and how will tenants and staff be notified before water is isolated?

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.

Independent licensed professionals

Answers first

Commercial in San Francisco — common questions

How is commercial plumbing different from residential?

Larger pipe sizing, different code classifications, mandated devices like grease interceptors and testable backflow assemblies, documented compliance reporting, and the fact that downtime has a direct revenue cost. Not every residential contractor is set up for it.

How often does a grease trap need service?

It is set by local health regulation and by how fast the trap fills — many jurisdictions require documented service on a fixed interval with retained manifests. Check your local requirement rather than waiting for an odor complaint.

Who handles backflow testing?

A tester with a state or water-purveyor backflow certification, which is a separate credential from a plumbing license. Most water purveyors require an annual test with the report filed directly with them.

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.

Which areas does PlumberCalifornia cover?

All of California: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.

Is PlumberCalifornia a plumbing company?

No. Independent licensed professionals perform and contract the work directly with you. PlumberCalifornia routes the request and links every page to the official California license register.

Does PlumberCalifornia charge homeowners anything?

No. PlumberCalifornia may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.

Does calling create any obligation to hire?

None. A call or a callback request is a conversation, not a contract. Scope, timing and price are only agreed if you decide to proceed with the professional handling San Francisco.
