Established in 1923 as the Building Contractors Association of Southern California, The Building Industry Association of Southern California, Inc. (BIASC), has been instrumental in helping the construction industry meet our region's demand for new housing, infrastructure, and the overall growth every community needs to thrive.  BIASC has over 1,050 primary members representing all professions associated with the building industry.

At BIASC, we believe that building and new home construction not only strengthens families, it stabilizes communities and fosters economic prosperity. With new homes and new growth come new schools, new fire stations, parks, cultural centers and more. Our members – builders, subcontractors, remodelers, designers, architects, engineers, sales and marketing professionals, law firms, manufacturers and more – all work together to create new and enhance exisiting communities across Southern California.

We are one association serving our members throughout Southern California with four Chapters delivering localized services to their respective territories:

BIASC Baldy View Chapter - San Bernardino, Inyo and Mono Counties

BIASC LA/Ventura Chapter - Los Angeles and Ventura Counties
