Who is covered
All buildings required to benchmark under LL84: buildings over 25,000 gross square feet or same-tax-lot aggregates over 100,000 square feet.
What the law requires
- Complete LL84 benchmarking to generate an ENERGY STAR score.
- Obtain the official energy efficiency grade letter from the City.
- Post the grade near a public entrance in a format and size specified by the City.
- Update the grade annually after each benchmarking cycle.
Filing frequency and deadlines
Penalty structure
Non-compliance with LL33 can result in the following penalties:
- $1,250 per year for failure to conspicuously display the energy grade.
Exemptions
- Same exemptions as LL84 — houses of worship and buildings under the square footage thresholds.
Recent updates and amendments
The City increased compliance checks by cross-referencing LL84 filings with LL33 grade postings. Buildings that file benchmarking data but fail to post the grade are now receiving targeted enforcement notices.
