The County of San Mateo Department of Housing has issued Request for Proposals 2027-RFP-00078 for the development and operation of affordable housing at 710 Hamilton Street in downtown Redwood City. The project involves the redevelopment of a county-owned site, formerly the San Mateo County Law Library, with a specific preference for housing public employees.

Proposals were due by November 6, 2026, and must include a conceptual proposal, developer qualifications, and a detailed application workbook covering unit mix, income targeting, and financial projections. The solicitation requires developers to demonstrate significant experience in the nine-county Bay Area, specifically with LIHTC-funded family housing projects, across development, ownership, and property management categories. Technical due diligence for the site includes a Phase 1 Environmental Site Assessment identifying a historical heating oil tank, a preliminary geotechnical study noting potential liquefaction and shallow groundwater, and a market appraisal valuing the property at 5.33 million dollars as of July 2026. Selected contractors must adhere to strict compliance standards, including California Labor Code prevailing wage requirements, ADA accessibility, HIPAA data privacy regulations, and general non-discrimination policies.
