Leddy Maytum Stacy Architects

What Leddy Maytum Stacy Architects does

Leddy Maytum Stacy Architects (LMSA) is a San Francisco-based architecture firm founded in 1979 (renamed under the current name in 2001) that provides design, planning, and project delivery services for mission-driven clients. The firm specializes in sustainable design, net-zero energy buildings, LEED certification, adaptive reuse, and universal design, with a client base concentrated in nonprofit organizations, educational institutions, affordable housing developers, and social justice organizations. Notable client engagements include UC Davis, Stanford, UC Berkeley, The Nueva School, Mercy Housing, BRIDGE Housing, and the UCSF Parnassus Heights project, the latter delivered through a joint venture with SCAPE Studio and Suffolk Construction.

The firm operates a project-based professional services model, generating revenue from architectural fees tied to individual commissions, with go-to-market driven by direct relationships, RFPs, and brand reputation rather than a sales-led pipeline. Core expertise spans higher education, affordable and supportive housing, civic and community facilities, and healthcare/campus planning, often delivered via joint-venture teaming on larger institutional projects (e.g., UC Berkeley Engineering Building with Payette). The technical foundation is centered on performance-based sustainable design rather than proprietary technological infrastructure.

LMSA holds the 2017 AIA National Architecture Firm Award—the AIA's highest firm-level honor—along with multiple AIA COTE Top Ten awards and a 2024 Just 2.0 Label certification that signals formal commitment to social justice and equity in design practice. The 2024 internal promotions of Alan Bohlander to Studio Director and Eric Elie and Nadia Fuertes to Associate Principals, following the death of founding principal Marsha Maytum, indicate a managed succession and retention of institutional knowledge. The firm remains a privately held partnership with no disclosed funding events, no headcount figures, and no revenue disclosures.
