Smart Local 105

What Smart Local 105 does

Smart Local 105 (legal name: Sheet Metal Workers Local 105) is a building trades union and chapter of SMART (Sheet Metal Workers' International Association), established in 1903 through the merger of Local 108 and Local 102. Headquartered at 2120 Auto Centre Dr, Glendora, California, the union represents skilled sheet metal workers across seven Southern California counties—Los Angeles, Orange, Riverside, San Bernardino, Kern, Inyo, and Mono—delivering a trained workforce to nearly 200 contractor partners. Members perform sheet metal layout, fabrication, and assembly in shops, and installation work on commercial and residential buildings, hospitals, stadiums, airports, and higher-education campuses, including signature projects such as SoFi Stadium, Intuit Dome, the Ports of Los Angeles, and Yaamava' Resort & Casino.

The union organizes its labor supply along five contractor-specialty networks: HVAC (commercial, residential, and shop), architectural sheet metal, Testing Adjusting and Balancing Bureau (TABB), commercial kitchen equipment, and duct cleaning. Eight geographically-dedicated business representatives manage relationships with contractors in each territory, while a partnership with So Cal JATC (Joint Apprenticeship and Training Committee) delivers registered apprenticeship programs across LA, Orange, San Bernardino, Riverside, and Bakersfield/Kern counties. Member benefits include health insurance, a defined-benefit pension plan, a 401(a) plan with record-keeping services, and—newly added in 2025—behavioral and mental health resources.

Local 105 generates revenue primarily through recurring union membership dues paid by its sheet metal worker members in exchange for representation, training coordination, benefits administration, and access to job placement through the contractor network. Pricing of dues is not publicly disclosed. As a member-governed, non-profit labor organization affiliated with SMART International, the local is owned and controlled by its membership rather than by external capital; it has no private equity, venture, or parent-corporate ownership. Inter-union coordination agreements with SMART Local 206 (San Diego) and SMART Local 104 District 3 (Ventura) extend jurisdictional coverage and benefit portability for members crossing into neighboring territories.
