First Phase of the Mission Bay South Block 4 East Project

The First Phase of the Mission Bay South Block 4 East Project is a 165-unit affordable rental housing development located on the southern portion of Mission Bay South Block 4 East in San Francisco, fronting China Basin and Third Streets, with a 160-foot-tall building that also includes a 1,253-square-foot ground-floor commercial space. The project is part of a larger 398-unit initiative, with the second phase pending rezoning approval. This phase is statutorily exempt from California’s Environmental Quality Act under AB 1449, contingent upon strict compliance with affordability, labor, and environmental criteria: all units must serve households at or below 70% of the Area Median Income, with a legally binding TCAC Regulatory Agreement in place, and more than two-thirds of the total square footage must be residential. Development must adhere to prevailing wage requirements, provide apprenticeship opportunities and health insurance to workers, and complete tribal consultation with mitigation measures for cultural resources. The site must not be located on sensitive lands, and any environmental contamination identified through a Phase I ESA must be remediated before construction begins. Design approvals include a D for D amendment permitting deviations from streetwall height limits and a Major Phase Amendment with building climate safety deviations, both approved via OCII Resolutions 28-2025 and 29-2025 on November 18, 2025. The Successor Agency to the San Francisco Redevelopment Agency through its Office of Community Investment and Infrastructure (OCII) is the lead agency overseeing approvals, with Jose Campos as the primary point of contact. The project is not subject to competitive procurement, nor does it contain formal FAR or DFARS contract clauses, solicitation numbers, pricing data, or traditional evaluation factors; instead, award is based solely on meeting statutory eligibility requirements under AB 1449. No contract type, payment terms, invoicing methods, contracting officer details, or formal inspection protocols are documented beyond regulatory compliance obligations enforced by OCII. The project is anticipated to proceed with tentative map approvals in 2026 following the December 4, 2025 filing of the Notice of Exemption.
