Assembly extends 'duty to mitigate' to commercial leases after heated debate

The Assembly on June 5 voted to expand New York’s duty to mitigate damages to commercial leases, passing A.2729 after a lengthy floor debate that centered on who should bear the burden when a commercial tenant breaches a lease.

Sponsor Assemblyman Otis told colleagues the bill brings the same ‘reasonable and customary’ mitigation principle the Legislature restored for residential tenants in 2019 into the commercial context and leaves judges broad discretion to weigh landlords’ resources and the unique facts of each case. He framed the change as a public‑policy tool to reduce unnecessarily vacant storefronts and the economic drag empty commercial space imposes on neighboring businesses.

Opponents, led by Assemblymember Flood and others, argued the bill shifts the burden of proof to landlords who have not breached contracts, could complicate mortgage underwriting and financing, and would increase litigation and administrative costs. Several members warned lenders rely on lease‑backed cash flows and that imposing a mitigation duty could raise borrowing costs or change lease terms.

Lawmakers also debated whether negotiated lease provisions and liquidated‑damages clauses would be preempted or altered in practice; sponsors said judges would resolve such fact‑specific conflicts. The measure passed on a recorded vote. The bill text specifies judges may consider ‘‘good faith’’ and ‘‘reasonable’’ mitigation efforts; supporters said that language protects landlords from unfair exposure. Opponents urged monitoring of downstream effects on lending and rental markets.

The next step is enrollment for the governor’s signature and, if signed, courts and litigants will test how the revised allocation of proof plays out in commercial disputes.
