History of the SMWIA, SMART & Local 206

Local 206 Sheet Metal contractors and members have helped construct some of San Diego’s most recognizable landmarks such as the San Onofre Nuclear Generating Station, Qualcom Stadium,  PETCO Park, San Diego County Central Courthouse and the San Diego Convention Center.

Other well known projects completed by Local 206 contractors and or members outside of San Diego include the NASA Jet Propulsion Laboratory in Pasadena and the Tesla Gigafactory in Reno Nevada.

Organized Sheet Metal Workers in San Diego date back to at least 1902 with two different organizations; the Amalgamated Association of Tin and Sheet Metal Workers and the Amalgamated Sheet Metal Workers International Association.

The Amalgamated Sheet Metal Workers’ International Association organized on May 1, 1896 granted a charter to San Diego Local Union No. 276 in October of 1902. Local 276 members met every 1st and 3rd Thursday at the Labor Temple located within the A. O. F. Hall at the intersection of H & 6 streets downtown San Diego, which is still in use today. The Local Union President was G.F. Schmidt who resided at 58 21st Street and the Recording and Financial Secretary was B. Neisser

In 1903, the Amalgamated Sheet Metal Workers' International Association merged with the Sheet Metal Workers National Alliance, a secessionist group that had broken away from the union in 1902; this merger creates the Amalgamated Sheet Metal Workers' International Alliance.

In 1917 Local 276 lost its charter with the Amalgamated Sheet Metal Workers' International Alliance after a long depression of business.

In 1918 sheet metal workers were re-organized and granted a new charter as Local 561. Local 561’s new president was Wm. G. Ehmcke.

In 1919 for an unknown reason Local 561 was issued a new charter as Local 206. The new President was W.L. Stevenson, the Recording Secretary was J.B. Phillips and D.R. Cobb was an undesignated officer.

In 1924 the Amalgamated Sheet Metal Workers' International Association absorbed the chandelier, brass, and metal workers, and once more changed its name—this time to the Sheet Metal Workers' International Association.

In 1927, members of Local 206 build structural reinforcements for Charles Lindbergh's aircraft, "The Spirit of St. Louis"

In 2012, the SMWIA merged with the United Transit Union (UTU) forming the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART). 

Local 206 members have provided skilled labor for more than a century now and we are proud to provide to owners, developers, and general contractors the highest trained and best skilled and equipped Sheet Metal Workers to the San Diego area. 

As we advance into the 21st Century and America's and San Diego's Energy Infrastructure turns to green buildings and alternative energies, we are grateful to bring over a century of expertise in the form of our members to this process and look forward to working on the public, commercial and industrial sheet metal and hvac projects of today and the future.
