Serving the Bay Area for more than a century, the American Institute of Architects, San Francisco Chapter, one of the largest of the AIA's nearly 300 chapters, represents more than 2,000 members in San Francisco and Marin County. Headquartered in the historic Hallidie Building—one of the world's first glass-curtain-wall-buildings, designed by Willis Polk and completed in 1917—AIASF is a resource for architect and allied community members, as well as the general public. AIASF strives 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 services, and professional excellence.
