The IIDA Story

Key Facts

The International Interior Design Association (IIDA) is the Commercial Interior Design Association with a global reach. We support design professionals, industry affiliates, educators, students, firms and their clients through our network of 15,000+ members across 58 countries. We advocate for advancements in education, design excellence, legislation, leadership, accreditation, and community outreach to increase the value and understanding of Interior Design as a profession that enhances business value and positively impacts the health and well-being of people’s lives every day.


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 would represent Interior Designers worldwide. Since that date, IIDA has worked to convene communities of Interior Designers across regions and specialties representing the interests for the entire community.
