Mamdani’s NYC housing plan tests three bold moves to lower costs

Mayor Zohran Mamdani’s “Block by Block” plan aims to slash NYC housing costs by boosting supply—targeting 200,000 new homes in 10 years with $2.5 billion in funding—through converting unused offices and hotels, building on public sites like Sunnyside Yards for a new complete neighborhood (requiring federal support), lowering insurance costs for affordable and rent-stabilized units, expanding ADUs and piloting basement apartments, and expanding tenant protections and downpayment/mortgage assistance for low-income buyers; success will depend on legislation and funding from local, state, and federal levels.
