Should your local government lower affordable housing requirements to spur more new construction?
Cambridge officials are weighing potential reductions to the citys inclusionary housing requirements to boost development feasibility. The proposal follows a challenging period for new projects marked by high interest rates and construction costs.
Why it matters
The city aims to stimulate development that has been stalled by current mandates, which developers argue are increasingly difficult to meet. The council is now evaluating adjustments to keep projects moving while maintaining income diversity.
Cambridge currently mandates that developments with more than 10 units set aside 20 percent for affordable housing. A study by RKG Associates indicated that maintaining current income diversity levels would require a 34 percent set-aside.
The players
Cambridge City Council
This is the primary legislative body responsible for governing the city and determining local zoning ordinances.
Patrick W. Barrett III
He is a plaintiff who filed a legal challenge against the city regarding its inclusionary housing policy.
Old North Development
This is a real estate development firm currently involved in a lawsuit against the city over zoning requirements.
RKG Associates
This is a consulting firm hired by the city to analyze the impact and feasibility of current housing policies.
Community Development Department
This local agency oversees urban planning and housing policy implementation for the city.
The details
The Community Development Department has suggested offering tax abatements and allowing developers to contribute payments into the Affordable Housing Trust as alternative feasibility strategies. Two active lawsuits, filed by Patrick W. Barrett III and Old North Development, currently challenge the constitutionality of the existing policy.
Timeline
1998: Cambridge first enacted its inclusionary zoning requirement.
2016: The city increased the inclusionary requirement to 15 percent.
2017: The requirement was further increased to 20 percent.
December 2025: Patrick W. Barrett III filed a lawsuit against the city.
September 2026: Old North Development filed a lawsuit challenging the policy.
Market Landscape
The city is evaluating the legacy of the 1998 Cambridge inclusionary zoning requirement to address current stagnation in large-scale residential projects. This shift marks an attempt to balance local affordability goals against a construction sector weakened by elevated interest rates.
Potential changes to housing mandates could influence the future availability of new residential units and the local housing supply. Residents and stakeholders may see shifts in the pace of local development projects based on the council's eventual decision.
The takeaway
The city is reevaluating whether its long-standing zoning goals remain sustainable given the current economic pressures on developers. Finding a balance between affordable housing mandates and construction viability is essential to ensuring continued development.
