Serving the Bay Area for more than a century, the American Institute of Architects, San Francisco Chapter (AIA San Francisco) is the third largest of the AIA's 300 chapters. Headquartered in the historic Hallidie Building—one of the world's first glass-curtain-wall-buildings, designed by Willis Polk and completed in 1917—AIA San Francisco is the Bay Area’s premier destination for architecture and design.

AIA San Francisco represents more than 2,000 members in San Francisco and Marin County. Our mission is to improve the quality of life in the Bay Area by promoting architecture and design. We further this goal through community involvement, education, advocacy, public outreach, member service, and professional excellence. 

Each month AIA San Francisco offers professional development and networking opportunities as well as public forums, tours, lectures, and gallery exhibitions that provide architects and design enthusiasts with many opportunities to explore the local built environment.
