How to Prepare Your NYC Building for Local Law 84, 97, and Climate Compliance
For many NYC building owners and property managers, climate compliance can feel like a moving target. One law focuses on benchmarking. Another focuses on energy audits. Another deals with lighting upgrades. Another sets emissions limits.
Which NYC Building Energy Laws Apply to Your Building?
If you own, manage, or oversee a building in New York City, one of the easiest ways to get overwhelmed is trying to sort out which energy laws actually apply to your property.
You may hear people mention Local Law 84, Local Law 87, Local Law 88, and Local Law 97 as if they are all the same thing. They are not. They are connected, but each one covers a different part of building energy performance and compliance.
Why Waiting Until April for Local Law 84 Can Cost NYC Buildings More

Is Your NYC Building 25,000 Square Feet or More? What It Means to Be a Covered Building in 2026

Local Law 84 vs Local Law 97 NYC: What’s the Difference?
NYC building compliance has a way of showing up as one vague thought: “We have something due by May 1.” Then reality hits. Is it Local Law 84 (benchmarking)? Local Law 97 (emissions reporting)? Both? And which portal are you supposed to use?
How NYC Building Energy Grades Are Calculated (And Why They Matter)
Walk into a large residential or commercial building in New York City and you may see a letter grade posted near the entrance: A, B, C, D, or F. That grade is not decorative. It represents your building’s publicly disclosed energy performance.
