What's Sustainable Buildings NYC?

This is a Department of Buildings website devoted to helping building owners comply with building emissions limits set in Local Law 97.

Who's affected?

Local Law 97 applies to large buildings in NYC, defined as 25,000 square feet or larger. Learn more about whether your building is required to comply with this law to avoid fines in 2025 and 2030. 

What do I have to do? How do I get help?

You may be required to make energy efficiency retrofits to reduce your buildings emissions by the 2025 deadline, or the more stringent 2030 deadline.
