LL97 For Affordable Housing

LL97 Compliance for Article 321 Buildings

Local Law 97 (LL97) establishes carbon emissions limits on New York City buildings over 25,000 gross square feet. While affordable or rent-regulated housing and houses of worship are not exempt from this rule, they may qualify for alternative or delayed compliance. Under Article 321, eligible buildings may choose from several pathways: 

  • Prescriptive Pathway: Implement all applicable Prescriptive Energy Conservation Measures (PECMs) by December 31, 2024, and submit a one-time report certified by a qualified retro-commissioning ("RCx") agent by May 1, 2025.

  • Performance-based Pathway: Meet the 2030 emissions limits for 2024 and submit a one-time report certified by a registered design professional (RDP) by May 1, 2025.
