The BIASC is one of the largest of its kind in the United States.

Our 1,300 members include the smallest to the largest home builders, developers, contractors, suppliers and skilled labor representing over 1 million employees and 10 billion in annual revenues, making us one of the largest building industry associations in the United States.

Our services are essential to the success of our members.

For over 99 years, we have provided a collective voice in the public policy arena helping builders continue to do business in California’s complex regulatory environment including front-line knowledge of proposed/new laws, policies, and procedures that could directly affect your business.

Members First

As a building/construction industry leader, we also provide first rate advocacy, policy expertise, and high-level networking that our members value and can count on. Our members are our first priority. Our passion is to help our members achieve their business goals and projections. Our services are essential to the success of our members in the building industry.


Our builders professional group is committed to preserving a legal/regulatory environment that is conducive to the success of home builders and affiliated trades, and to helping members function within that environment.


Our focus on integrity and compliance ensures that we operate legally and ethically in our business conduct every day. Following the integrity process in all our business activities enables us to comply with all applicable federal and state laws, rules and regulations while representing our core members.


Every member in our home builders organization is important to us. We are committed to providing professional services to our members, and to giving all of our members the individual attention and respect they deserve. We are also committed to serving our industry through active participation in legislative and environmental issues and by seeking new, creative ways to serve the needs of the unserved and under-served segments of our industry.


Good leadership will keep at it . Good leadership will follow-up. Good leadership will think, rethink, frame and reframe an issue, idea or challenge. It’s about preparation and planning. The only way to lead is by allotting time to strategize about future hurdles that will impact our industry. This is the BIASC’s philosophy.



The Building Industry Association of Southern California was first organized in 1923 as the Building Contractors Association, covering the local Los Angeles area.


It incorporated 10 years later in 1933 as the Building Contractors Association of Southern California, Inc.


The Builder-Developer Chapter withdrew from the Building Contractors Association (BCA) and formed a Home Builders Institute charter, which evolved into the Home Builders Association of Los Angeles, Orange and Ventura counties (HBA).


The BCA and the HBA joined forces and consolidated into the Building Industry Association of California, Inc. It formally changed its name to the current Building Industry Association of Southern California in 1978.
