Welcome to the Homepage for Sprinkler Fitters Local 483

For over 75 years the Sprinkler Fitters of Local 483 have installed, tested and maintained Commercial and Residential Sprinkler Systems throughout the San Francisco Bay Area.  We are proud to have installed these necessary life saving and property saving systems that are so important to our way of life.  We take our jobs extremely serious because you only get one opportunity to install these systems properly. For this reason, companies throughout the Bay Area continue to call on us for new and retrofit projects, but our job does not end there.

The California State Fire Marshalls office in conjunction with the National Fire Protection Association (NFPA) has strict requirements for the maintenance, inspection, testing and service of these life safety systems.  If you work or live in a facility that does not have these important life saving systems, or need information on maintenance and servicing, please contact us immediately. You never know when a fire could strike your home or business.

Please take the time to learn more about us through our website and we welcome any and all correspondence and feedback!
