Builders Network

BIASC is recognized as the strongest voice in Southern California influencing legislative/policy issues on behalf of the industry. Our members and their interests are represented in policy decisions.

Membership Discounts

BIA members receive several valued discounts and savings opportunities offered by several of our corporate sponsors and affiliates. Receive members-only content on issues directly affecting your business.
