Founded in 1887, the Washington Chapter of the American Institute of Architects serves the Nation's Capital, functioning as both the "local" and "state" component of the AIA for the District of Columbia.

The Chapter was intimately involved in the design and planning of Washington, and continues to play an active role in city development today. The Chapter House is a typical Dupont Circle row house built in 1917. It houses the offices of the Washington Chapter / AIA and The Washington Architectural Foundation, a non-profit foundation established by the Chapter in 1988 to raise public awareness of the built environment. In addition to a superb board room for meetings, the Chapter House maintains The Architect / Client Resource Center, a library of portfolios on local architects and architectural firms.
