TNDC and CCDC complete $153m OMA-designed affordable housing block in San Francisco's Haight-Ashbury

A $153m affordable housing development at 730 Stanyan Street in San Francisco, California opened to residents on 29 July 2026 after eight years of planning^[1], marking the completion of OMA's first 100% affordable housing project in the United States^[1]. The eight-storey, 194,000-sq-ft complex delivers 160 permanently affordable apartments on a former fast-food site at the intersection of Haight and Stanyan streets, adjacent to the entrance of Golden Gate Park^[1].

Who built it and who it serves

The project was developed jointly by the Tenderloin Neighborhood Development Corporation (TNDC) and Chinatown Community Development Center (CCDC), two San Francisco nonprofits operating as 50/50 co-developers^[1]. OMA's New York office, led by partner Jason Long, designed the building alongside San Francisco-based Y.A. Studio^[1].

The 160 units are targeted at households earning 25-80% of San Francisco's area median income, which stands at roughly $162,000 for a family of four^[1]. The unit mix is weighted toward families:

• 35 studios
• 43 one-bedroom apartments
• 42 two-bedroom apartments
• 40 three-bedroom apartments

12 units are set aside for families exiting homelessness and 20 for transitional-age youth (ages 18-25)^[1]. On-site social workers, front-desk coverage, and property management are built into the operating model to support residents in maintaining stable tenancy.

How the project was financed

The total development cost came to $153.2m, assembled from multiple public and private sources^[1]. Key funding streams included:

• City MOHCD loans: $51m committed
• City-acquired land value: $15.9m
• Federal low-income housing tax credits: $7.38m annual reservation from the California Tax Credit Allocation Committee
• State HCD loans and infill infrastructure grants
• The voter-approved 2019 San Francisco Affordable Housing General Obligation Bond

The San Francisco Office of Housing and Community Development served as bond issuer, with California Housing Partnership Corporation as investor consultant.

Design approach

The massing responds directly to the scale of Haight-Ashbury's historic residential streetscape^[1]. Two four-storey volumes line Haight and Waller streets to the north and south, while a taller eight-storey section sits between them^[1]. That central volume curves inward to create three ground-level courtyards - a garden, a children's play area, and a gathering space open toward the park^[1].

The exterior is clad in modular glass-fibre-reinforced concrete panels whose undulating profiles loosely echo the bay windows of the surrounding Victorian architecture without imitating its ornament. Corner extensions on the upper floors maximise apartment sizes and views over Golden Gate Park^[1].

Ground-floor space is allocated for an early childhood education provider, a senior centre, a transitional-age youth drop-in centre, and a low-cost café or restaurant - making the building the first affordable housing development in the Haight-Ashbury neighbourhood in nearly 20 years, according to TNDC.

The building is now fully occupied^[1]. The project's financing structure - layering city loans, state programmes, federal tax credits, and a voter-approved bond - will be closely watched by other California nonprofits attempting to replicate deeply affordable, design-led delivery on infill sites where land costs alone can derail feasibility.
