The Building Industry Association of Southern California (BIASC) is a nonprofit trade association representing nearly 1,000 member companies. Our mission is to promote and protect the industry to ensure our members’ success in providing homes for all Southern Californians.

Home ownership not only strengthens our families, it also stabilizes communities and fosters economic prosperity.

With new homes come new schools, new fire stations, parks and cultural centers. Our members – builders, subcontractors, remodelers, designers, architects, engineers – all work together to build communities for families to call home.
