Requires lighting upgrades and electrical submetering for covered NYC buildings and spaces, as amended by subsequent legislation.
New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.
Why it matters
Lighting and submetering are separate workstreams with different applicability details. Review the current covered-building scope, exceptions, submission instructions, and completion records. The original 2025 milestone is not a future planning date; unresolved work and filings should be checked during acquisition or refinancing.
In practice
A project example
An owner with LED lighting still verifies whether tenant submetering and required reporting were completed rather than assuming that the lighting project satisfied the entire law.
