This is an affordable housing development jointly developed by Tenderloin Neighborhood Development Corporation (TNDC) and Young Community Developers (YCD), with LMSa and Suffolk Construction selected as Design-Builder. The San Francisco Contract Monitoring Division (CMD) has assigned a 25% Small Business Enterprise (SBE) professional services subcontracting goal and a 25% SBE construction subcontracting goal; only SBE-certified subcontractors may be utilized to meet these goals, and firms must demonstrate good faith efforts in SBE utilization.

The project is a 127-unit mid-rise affordable family residential development (nine stories) at the corner of Pennsylvania Avenue and Mariposa Street, zoned Urban Mixed Use with a 40-foot height limit. The scope is contracted with TNDC. Design development is scheduled September 2026 through February 2027, construction documents February 2027 through June 2027, and construction administration approximately 21 months beginning September 2027 (estimated completion June 2029). Work will be authorized by phase with potential pauses for external funding, entitlements, and permitting approval; the Developer reserves the right to terminate the contract or place the project on indefinite hold.

Proposed consultants must carry Professional Liability insurance of $2 million per claim / $4 million annual aggregate, Commercial General Liability of $1 million per occurrence / $2 million aggregate, and Business Automobile Liability of $1 million. Evaluation criteria weight project approach (15 points), proposed personnel experience (20 points), firm experience with similar-sized projects (20 points), competitive fees and standard contractual terms (15 points), ability to contribute to the 25% SBE goal (15 points), familiarity with San Francisco permitting (10 points), capacity and ability (10 points), and design-build project experience (10 points); insurance compliance is pass/fail. Questions are due September 4, 2026, with answers projected by September 9. Award is projected for September 18, 2026. The project is funded through the San Francisco Mayor's Office of Housing and Community Development (MOHCD) and anticipated to be SFPUC-powered.
