Benchmarking.NYC confirms whether your building is covered by Local Law 88, coordinates the licensed professionals who complete and attest to the work, and files the report with DOB.
Request an LL88 Review
Local Law 88 requires owners of covered New York City buildings to bring lighting up to the NYC Energy Conservation Code and to measure electricity in large tenant spaces with sub-meters. The work deadline was January 1, 2025, and buildings that have not yet shown compliance still need to file a report with the Department of Buildings (DOB).
Benchmarking.NYC confirms what the law requires for your building, coordinates the work and the professional attestations, and submits the LL88 report.
Based on Department of Finance records, covered buildings are:
One-, two- and three-family homes and garden-style apartments are not covered buildings. Residential buildings and landmarked buildings that meet the size thresholds are not exempt.
By January 1, 2025, lighting systems in covered buildings had to meet the NYC Energy Conservation Code standards for new systems. Lighting upgraded after July 1, 2010 that met the code in effect when it was installed already complies. The upgrade covers the entire building, including tenant spaces under 5,000 square feet. Lighting inside dwelling units in occupancy groups R-2 and R-3, and occupancy group A-3 space within a house of worship, is exempt.
The electricity used in each covered tenant space must be measured by one or more sub-meters, and tenants must receive monthly statements. A covered tenant space is either:
A space whose electricity is already measured by a meter dedicated only to that space does not need a sub-meter. Dwelling units in occupancy groups R-2 and R-3 are also excepted.
Reports are filed per building in the BEAM portal, and a filing fee applies (DOB set it at $115 for 2025 reports, covering both lighting and sub-metering). The attestations must be signed by a registered design professional, a licensed master electrician or a licensed special electrician.

We check the building against the DOB Covered Buildings List and identify every covered tenant space.
We review the existing lighting against the energy code and check which tenant spaces already have dedicated meters or sub-meters.
Licensed electricians handle any lighting upgrades and sub-meter installations, with permits where DOB requires them.
A qualified professional signs the attestations, and we file the report in BEAM with the tenant space list and a sample monthly statement.
Our Local Law 88 service may include:
LL88 penalties are assessed every year until the building shows compliance, and missing sub-meters are fined for each covered tenant space. Each year without a filed report adds another penalty.
LL88 also affects Local Law 97. Owners who want to claim good faith efforts to reduce LL97 penalties must attest that lighting upgrades and tenant sub-meters are complete.
Benchmarking.NYC treats LL88 as part of the building's full Local Law record. We connect the lighting and sub-metering filing to LL84 benchmarking and LL97 reporting, coordinate the licensed electricians and attesting professionals, and file the report so the building's record matches the work that was done.
