BAC Local 4

What BAC Local 4 does

BAC Local 4 California is a labor union local operating under the International Union of Bricklayers and Allied Craftworkers (BAC), representing skilled craftworkers across 13 Southern California counties: Los Angeles, Orange, San Diego, Imperial, Riverside, San Bernardino, Inyo, Mono, Tulare, Kern, Ventura, San Luis Obispo, and Santa Barbara. Headquartered at 2679 Sierra Way in La Verne, the union represents bricklayers, stone and marble masons, refractory specialists, restoration masons, pointers/caulkers/cleaners, and — since a 2016 jurisdictional expansion — tile, marble and terrazzo workers. Its core function is collective bargaining, apprenticeship training, and member benefits administration. It does not develop proprietary technology; its digital footprint consists of a Member Portal and BAC Mobile App for dues payment, plus standard social media accounts.

The union runs two apprenticeship pipelines — the Brick Masons program (bac4training.org) and the Tile Layer/Tile-Marble Finisher/Terrazzo Joint Apprenticeship Committee program (tiletraining.org) — supplemented by advanced training and continuing education through the International Masonry Training and Education Foundation (IMTEF) and a 50+ year Job Corps contractor relationship through the International Masonry Institute (IMI). Member benefits include health/welfare and pension trust funds administered by Benesys (covering Tile Insurance Trust Fund, Brick Masons Trust Fund, Santa Barbara Masonry Trust, Bricklayers Local #11 Trust), scholarship programs (Rusty Trowel Gang and US Bates), and a confidential Member Assistance Program (MAP) for mental health support. Signatory contractors receive labor compliance services for prevailing wage and California Labor Code compliance.

The revenue model is recurring union membership dues — effectively a subscription model — used to fund local staff, legal/negotiation/arbitration costs, and per-capita remittances to the International Union, State Building Trades, and local Building Trades Departments. Two customer segments are served simultaneously: individual craftworkers (members) seeking fair wages, benefits, training, and representation; and signatory contractors seeking access to a trained labor pool, prevailing wage compliance expertise, and PLA-eligible workforce. The organization is membership-governed with elected officers (President, Secretary/Treasurer, Management Committee) and deploys field representatives across each major sub-region.

Broad incumbents

• International Union of Bricklayers and Allied Craftworkers (IUBAC): The international parent body of BAC Local 4 and all other BAC locals across North America. Directly comparable because it aggregates the same craftworkers, runs the national CBA framework, and manages the training and benefit infrastructure that the local depends on.
• Laborers' International Union of North America (LIUNA): Large U.S./Canadian construction labor union representing laborers on building trades job sites. Comparable as a peer labor organization serving construction trades with collective bargaining, training, and benefits delivery, though it covers a different craft scope.
• United Brotherhood of Carpenters (UBC): Major North American building trades union representing carpenters and related trades. Comparable as a peer construction labor union with parallel apprenticeship, collective bargaining, and member-benefit structures, though covering a different craft.
• International Union of Painters and Allied Trades (IUPAT): Large U.S./Canadian building trades union for painters, glaziers, and finishing trades. Comparable as a peer labor union with similar member services, training programs, and signatory-contractor model, though serving a different craft segment.
• International Union of Operating Engineers (IUOE): Building trades union representing heavy-equipment operators and related construction workers. Comparable as a peer construction labor organization with parallel apprenticeship, training, and collective bargaining structures serving the same job sites.
• International Brotherhood of Electrical Workers (IBEW): One of the largest U.S. construction labor unions representing electrical workers. Comparable as a peer labor organization with the same membership, training, and CBA mechanics, though focused on a different craft.
• SMART (Sheet Metal, Air, Rail, Transportation): North American union representing sheet metal workers in construction and other industries. Comparable as a peer building trades labor union with parallel apprenticeship programs, CBAs, and benefits delivery, though serving a different skilled craft.

Direct peers

• BAC Local 3 California: Sister BAC local covering Northern California under the same international union. Identical business model — collective bargaining, apprenticeship, member benefits — and directly comparable products, services, and member segments.
• BAC Local 1 (New York): Another BAC local with the same craftworker representation model but operating in a different geography (NYC metro and surrounding boroughs). Comparable in service offerings and member segments, with PLA wins like the $7B NYC project portfolio.
• Operative Plasterers and Cement Masons International Association (OPCMIA): Closest craft-adjacent labor union — plasterers and cement masons work alongside BAC bricklayers/tile setters on the same job sites. Highly comparable member benefits, training, and signatory contractor model, with overlapping geographies and many shared building-trades councils.
