Key Dates for 2026
The 2026 compliance calendar includes several overlapping NYC energy law deadlines that building owners and property managers should be tracking now to avoid filing delays, penalties, and unnecessary year-end pressure. The first major deadline is March 31, which applies to properties due for Local Law 87 filing in the 2025 cycle. For buildings that have not yet completed audit and retro-commissioning work, this is the time to confirm submission status and ensure all supporting documentation has been finalized.
May 1 is one of the most important compliance dates of the year, marking the filing deadline for Local Law 97 annual emissions reporting, Local Law 84 benchmarking, and Local Law 88 lighting and submetering compliance for buildings that remain outstanding. Buildings that are not prepared to submit Local Law 97 by May 1 may still apply for an extension by June 30, which moves the final filing deadline to August 29. For many properties, this is also the ideal period to review emissions exposure, verify utility data, and confirm whether reporting responsibility is being handled internally or through an advisor.
Additional deadlines continue through the second half of the year. August 1, November 1, and February 1, 2027 represent quarterly Local Law 84 benchmarking milestones that remain important for newly covered or recently transferred properties. In the fall, October 1 is when Local Law 33 energy efficiency grades become available through DOB, followed by the October 31 deadline to post the grade in a visible public location within the building. December 31 closes the year with the Local Law 87 filing deadline for buildings due in the 2026 cycle, making early scheduling of inspections and engineering reviews especially important for properties entering that filing year.
