The Local Law 88 Checklist.
Four questions tell you whether LL88 is handled at your NYC building — size threshold, lighting, tenant submetering, and the filing. Run through them in two minutes, then take the one-page PDF with you.
That's the size where LL88 kicks in. Smaller than that, and you can stop right here.
LL88 asks for efficient, code-level lighting. Older fixtures are the usual gap — and one of the easier things to sort out.
Bigger commercial tenants get metered on their own. Common in office and mixed-use buildings, and often already in place.
The step most owners miss: doing the work and filing it are two different things. The good news — if the work is done, the filing is the easy part.
Want it on paper? The same checklist, one page — pass it to whoever manages the building.

The LL88 deadline passed in January 2025. A covered building (25,000sq ft and up) that hasn't filed accrues a $1,500 penalty per missed report, every year, until the filing is on record — even when the physical work is already done.
Thresholds, submetering triggers, and the full penalty schedule are on the Local Law 88 law page. If any check above didn't pass, the LL88 compliance service closes it out: survey, report, and the certified filing.
A Check Didn't Pass? Start with the Survey.
We survey the building, tell you what's needed — or that nothing is — and file the attestation that closes LL88 out. Get a proposal, or check a building free first.
Estimated penalty amounts and compliance pathways may vary annually. Projections are intended to aid compliance planning but may not exactly match actual penalties. The compliance pathways are based on DOB's Covered Buildings List, which was compiled using preliminary data subject to change. This information is intended only as a reference for building owners to consider in consultation with legal representatives and registered design professionals (RDPs). LuxNet's compliance check is informational and does not constitute legal or financial advice. Actual fines depend on building specifics, filing history, and DOB enforcement.
