IIDA was founded in 1994 as the result of a merger of the Institute of Business Designers (IBD), the International Society of Interior Designers (ISID), and the Council of Federal Interior Designers (CFID). The goal of the merger was to create an international association with a united mission that represents Interior Designers worldwide.

Founded in 1995, the Southern California Chapter is one of the largest chapters with over 800 members throughout Los Angeles, Orange County, San Diego, Santa Barbara, and the Inland and Desert Empires.

IIDA strives to create a strong niche for the most talented and visionary Interior Design Professionals, to elevate the profession and lead the way for the next generation of Interior Design innovators. Our Association provides a forum to demonstrate design professionals’ impact on the health, safety, well-being and virtual soul of the public, balancing passion for good design and strategy for best business practices.
