Closes the obligation
Got a proposal years ago and never moved? Did the work but never filed?

Either way the obligation is still open, and the penalty is accruing. The path is the same: survey, report, filing. If the building is already in good shape, the survey documents that and the filing says so.

How It Works

The whole engagement is three steps — a focused version of our compliance survey. We tell you what the building needs, or that it needs nothing. Then we file:

Start hereStep 01

LL88 Survey

A fixture-level walk of the building — lighting, controls, and tenant submetering — during normal business hours. One visit covers both halves of the law.
Step 02

Compliance Report

A verdict for every surveyed space. Deficiencies carry their energy-code reference; recommendations carry numbers — wattage removed, projected savings, simple payback. If the building already complies, the report says so.
Step 03

We File It

We certify and file the attestation — lighting and submetering in one filing. The penalty clock stops with the filing, not the work.

Own more than one covered building? We survey and file whole portfolios in one cycle, and multi-building work is priced at a bulk discount.

If Work Is Needed, It Pays for Itself

The penalty buys nothing; the upgrade pays back. LED fixtures draw a fraction of the wattage of the lamps they replace, and networked lighting controls save about 47% more lighting energy on top of that on average — roughly 70% of projects save 30% or more (DesignLights Consortium, 2017). Every recommendation in the report carries its own numbers: wattage removed, projected savings, simple payback.

Controls are our core trade. If the report calls for occupancy sensors, daylighting, or a networked system, our NLC design & commissioning service designs the system, oversees the install, and commissions it so the savings actually show up on the bill.

We finished the lighting work but never filed. Can you just close it out?
Yes — it's the most common case we see. The obligation stays open until the attestation is on record, even when the work is done. We document the existing condition, confirm it complies, and file.
What does waiting actually cost?
$1,500 a year for the missing lighting report and $1,500 a year for the missing submetering report — $3,000 a year, accruing until both are filed. Buildings with required-but-missing tenant submeters can add $500 per meter per year on top.
Who certifies the LL88 filing?
A registered design professional, a licensed master electrician, or a licensed special electrician. We handle the certification and the filing — you don't need to line anyone up.
Does this cover submetering, not just lighting?
Yes. LL88 has two halves: lighting upgraded to the energy code, and electrical submetering of covered tenant spaces (a tenant over 5,000 sq ft, or a shared floor over 5,000 sq ft). One survey and one filing cover both.
What if the building isn't compliant yet?
The report lists each deficiency with its code reference and what fixing it costs and saves. The survey and filing price doesn't change; any corrective work is scoped separately, and controls work runs through our NLC design & commissioning service.
It's a residential building. Does LL88 apply?
Partly — and the building-wide filing is still required. Apartments themselves are exempt, but common areas (lobbies, hallways, garages) and any commercial space must meet the energy code. Mixed-use buildings with ground-floor retail almost always have an obligation.
