Local Law 97: What It Means for Your Building
NYC Local Law 97 requires buildings over 25,000 square feet to meet carbon intensity limits starting in 2024, with limits tightening through 2030 and beyond. Buildings that exceed their cap face penalties of up to $268 per ton of excess CO₂ — per year.
For multifamily buildings — where heating, domestic hot water, and common area loads drive most of the carbon — controls upgrades are typically the highest-impact, lowest-disruption path to compliance.
