OMA/Jason Long and Y.A. Studio Complete 730 Stanyan: 160 Permanently Affordable Homes in Haight-Ashbury

# Project in brief OMA, led by partner Jason Long, together with San Francisco–based Y.A. Studio, has completed 730 Stanyan, a mixed-use, 100% permanently affordable housing development at the corner of Haight and Stanyan Streets in San Francisco's Haight-Ashbury. Tenderloin Neighborhood Development Corporation (TNDC) and Chinatown Community Development Center (CCDC) developed the project. Residents are now occupying the building.

# What the building does 730 Stanyan replaces a former fast-food site with a 194,000-square-foot structure that combines housing and community amenities. The development delivers 160 permanently affordable homes targeted to low-income families, formerly unhoused families, and Transitional Age Youth (TAY). More than half the apartments are configured as two- and three-bedroom units to support family households.

# How the design responds to the neighborhood The building massing responds to the surrounding historic residential scale. Two four-story volumes line Haight and Waller Streets while an eight-story section sits between them. This arrangement produces a sequence of courtyards and terraces that bring daylight, outdoor space, and views into the interior of the project. Corner conditions were emphasized to create efficient apartment layouts and increase natural light and park views, particularly toward Golden Gate Park at the site's edge.

# Materials and construction strategy The exterior uses a system of modular glass fiber–reinforced concrete (GFRC) panels with a wave-like profile. Windows and ventilation louvers are incorporated into the prefabricated panel elements. The team developed this facade system to streamline construction, lower envelope costs, and provide a durable finish appropriate for the neighborhood scale.

# Program and occupancy The program emphasizes family housing and a mix of shared outdoor and community spaces. The building's unit mix and courtyard strategy aim to strengthen connections among residents and between the building and the adjacent park. With full occupancy, 730 Stanyan represents OMA's first completed 100% affordable housing project in the United States and joins the firm's recent completed projects worldwide across housing, cultural, and mixed-use types.

# Context within OMA's recent work Archival notes list recent OMA-completed projects including The Martin in Amsterdam, Hangzhou Prism in China, and interventions for the Edo-Tokyo Museum in Japan. 730 Stanyan is positioned within that portfolio as the firm's completed affordable housing project in San Francisco.
