NYC Mayor Zohran Mamdani

I was interviewed for AMNewYork’s story, Mamdani’s First 50 Days. It reads, in part,

For Professor David Reiss, a Cornell University housing expert and former chair of the Rent Guidelines Board, the mayor’s housing orientation so far is unmistakably pro-tenant, but it also underscores deeper challenges.

“He’s clearly pro-tenant,” Reiss said, noting Mamdani’s rhetoric, appointments, and actions such as launching his rental rip-off hearings and the revival of the Mayor’s office to protect tenants. But he cautioned that short-term policies aimed at controlling tenants’ costs must also account for the long-term viability of the housing stock.

“Are you pro-tenants five years, 10 years, 15 years down the line?” Reiss asked, pointing to the risk that buildings with constrained revenue might struggle to cover unavoidable expenses like property tax, insurance, and mortgage payments without meaningful engagement.

Reiss traced much of this pressure to state rent restrictions, which eliminated several mechanisms that previously allowed landlords to raise rents between tenancies. Under current conditions, he said, the annual RGB adjustments are often the only permissible rent increases, which, in recent years, have been modest in the view of landlord groups.

If rents are capped or frozen, his view is that the city will have very few tools to ensure financial stability without subsidies or cost reductions — whether direct (financial support) or indirect (tax relief or reduced operating costs).

“You have very few tools,” he said. “They usually involve somehow reducing costs directly or indirectly, or increasing income by subsidizing,” Reiss said that any meaningful approach will have to consider how the city allocates limited funds, especially in the face of a budget gap that has already pushed the administration to consider rainy day funds and reserve drawdowns elsewhere.

That tension between immediate affordability and long-range health of the housing stock frames much of the current policy conversation. Reiss said the rent freeze itself — assuming it survives legal and procedural hurdles — would represent a significant political success if delivered, given that it was a core campaign pledge. But he stressed that a broader housing strategy must also ensure that rent-regulated buildings can cover ongoing costs without descending into default or neglect.

“Success for the Mamdani administration,” Reiss said, “is to thread the needle between his expressed statement of reducing rent increases or rent freeze on the one hand, but ensuring that the housing stock has enough income to support itself — not just for this year, but for three years, five years, seven years down the line.”
