Affordable Housing Nexus Study for Mandatory Housing Affordability Requirements

The City of Seattle's Office of Planning and Community Development is soliciting proposals for an Affordable Housing Nexus Study to support the Mandatory Housing Affordability program. The primary objective of this study is to quantify the demand for affordable housing generated by specific market-rate residential development prototypes, which will inform updated program requirements. The project is structured into four key tasks: project kickoff and coordination, market overview and affordability analysis, residential demand analysis, and the preparation of a final summary report. The City intends to execute the contract by December 15, 2026, with initial results expected in March 2027. Eligible consultants must have completed an affordable housing nexus study for another municipality within the last ten years. Proposals will be evaluated based on experience with nexus studies, project approach, team qualifications, and cost. The selected independent contractor must maintain specific insurance coverages, including one million dollars for general liability, automobile liability, and professional liability, and must hold both Seattle and Washington State business licenses. Submissions are due by November 10, 2026, via the City's electronic procurement portal.
