In Design
Designing a Home for San Francisco's LGBTQ+ Seniors
At the corner of Market Street and Duboce Avenue, at the threshold between the Castro District and the Market-Octavia corridor, a 15-story tower is taking shape. When complete, 1939 Market Street will provide 187 affordable homes for seniors with a particular focus on LGBTQ+ elders, long-term HIV/AIDS survivors, formerly homeless individuals, and veterans. Y.A. studio is part of the design team bringing this project to life, working alongside the architect of record, Paulett Taggart Architects.
This project is a considered response to a real and urgent need: affordable, affirming, community-rooted homes for a population that has too often been overlooked.
A Site with Meaning
The City and County of San Francisco acquired the Market Street parcel in 2020 with a specific vision in mind. The site sits at a culturally significant gateway, steps from the San Francisco LGBT Center and the Bob Ross LGBT Senior Center. MOHCD's financing documents describe the project as part of an expanding LGBTQ-centered "campus" — a cluster of resources that together support community connection, access to services, and seniors' ability to age in place with dignity.
That context shaped every design decision. A building in this location isn't a background object. It carries meaning for the neighborhood, and the design team took that responsibility seriously.
The Design Response
A Building That Reads as Belonging
The site's triangular geometry presented a natural opportunity, and the building's flatiron massing responds directly to the lot's shape — a form that is practical and visually distinctive, marking the corner with confidence. At the street level, ground-floor commercial and service spaces activate the sidewalk, while lobby and property management functions keep the building open and legible to the community it serves.
Colored glazing along Market Street forms a vertical rainbow element visible along the corridor — an expression of identity that is architectural rather than just decorative. Recessed balcony elements along Duboce, activated by LED lighting, continue that language at a different scale. On the second floor, an open podium space connects to the community room, creating an indoor-outdoor gathering zone that supports resident programming and social life.
These are design choices, not afterthoughts. They reflect the team's commitment to creating a building that residents can recognize as their own.
Built for the Future
1939 Market Street is designed to be all-electric. The project is pursuing GreenPoint Rated Gold certification, with a comprehensive sustainability strategy that addresses not only energy but long-term climate resilience.
The California Strategic Growth Council's project profile identifies specific resilience measures built into the design: a backup-powered community room, passive shading, MERV-14 air filtration for improved air quality, and native landscaping. These are not aspirational gestures. They are practical provisions for a population that includes elderly residents who may be more vulnerable to heat events, poor air quality, and other climate-related health risks.
Situated within a half mile of multiple major transit lines, 1939 Market Street is transit-oriented housing at its most direct. The AHSC award scope extends beyond the building itself, funding signal priority improvements on six MUNI lines, protected bikeways, and sidewalk repairs in the surrounding corridor, connecting the building's sustainability goals to the neighborhood infrastructure that residents will actually use.
A Complex Project, Navigated with Precision
Streamlined Approvals Through SB 35
Getting a 15-story affordable housing tower approved in San Francisco is not simple. This project navigated that process through California's SB 35 ministerial approval pathway, combined with a State Density Bonus, which allowed the 187-unit, 159-foot building to move forward on a site zoned for significantly lower density. The SB 35 application was submitted in November 2022 and received final planning approval by May 2023, reflecting the team's preparation and the project's strong alignment with state housing policy.
Financing That Reflects the Project's Ambition
In December 2025, the project was awarded $47 million through California's Affordable Housing and Sustainable Communities (AHSC) Round 9 program — one of the most competitive state funding programs in the country. That award, combined with a City gap loan from MOHCD, tax-exempt bonds, and 4% Low-Income Housing Tax Credits, assembles a capital stack commensurate with the project's scale and its depth of community benefit.
The affordability structure reflects a genuine commitment to the city's most vulnerable seniors. Units are distributed across a range of income levels — from extremely low-income households at 15% AMI up to 60% AMI — with dedicated operating subsidy programs for formerly homeless seniors, veterans, and extremely low-income residents. This is not a project that uses "affordable" as a threshold. It is one that builds affordability into every aspect of its program.
Partnership as Practice
Y.A. studio joined this project as associate architect, working within a team that includes Paulett Taggart Architects as architect of record, co-developers Mercy Housing California and Openhouse, general contractor Swinerton, and MEP engineers Meyers+. Each partner brings distinct expertise. What makes the collaboration work is a shared commitment to the people this building is meant to serve.
Openhouse — a San Francisco organization focused on LGBTQ+ seniors — serves as on-site services partner and co-developer, ensuring that the building's programming and operations reflect the lived experience of its intended residents. Their involvement is not a checkbox. It is integral to how the project was conceived, funded, and designed.
Looking Ahead
Construction is anticipated to begin in late 2026, with completion projected around 2029. When it opens, 1939 Market Street will offer 187 seniors a home that was designed with care, built with rigor, and grounded in a genuine understanding of the community it will serve.
For Y.A. studio, this project reflects what we believe affordable housing design can and should be: technically precise, financially viable, and deeply human.
