Note that these plumbing systems include plumbing appliances, plumbing appurtenances, and plumbing fixtures.

    Willfully disobeying, refusing to comply with, neglecting, or even omitting any provisions of the city's plumbing code when carrying out plumbing work can result in severe penalties.

    Insurance is an important qualification to look out for when you want to hire a plumber in San Francisco.

A total of four fatal work-related injuries were also recorded in California alone by the state's Department of Industrial Relations during this period. Hiring a plumber that is licensed and insured protects you from financial liabilities if an on-the-job injury or accident occurs during your project. As such, even though plumbers in San Francisco are not mandatorily required to carry commercial general liability insurance, the CSLB strongly recommends that they do so. However, licensed plumbers in the city are required to post a surety bond of $15,000 to maintain their licenses, and any plumber that has at least one employee is also required to carry worker's compensation insurance. You should always confirm that any plumber you wish to hire meets these requirements before finalizing any hiring agreements.
