Local Law 88/09 Lighting Upgrades and Submetering requires lighting upgrades in non-residential buildings and non-residential spaces within residential buildings (i.e. ground floor retail, professional office, etc.) but excludes common areas and dwelling units; and requires the installation of electric sub-meters in commercial tenant spaces in certain buildings.

Lighting Upgrades

Incandescent bulbs. LEDs

LL88/09: LED exit sign uses much less energy than Incandescent bulbs.

Upgrades apply to base building and non-residential spaces within multifamily buildings (i.e. ground floor retail, professional office, etc.)

Building owners must upgrade their lighting systems to current NYC Energy Code Standards:

  • Interior lighting power
  • Lighting controls
  • Exterior Lighting
  • Tandem Wiring
  • Exit Signs (see the LED exit sign below)

This law excludes dwelling units and spaces serving them, including hallways, laundry rooms and boiler rooms. It also excludes Houses of Worship.

The deadline is January 1, 2005 and the building owner must file a report certified by a Registered Design Professional that this work has been completed.

See the Comparison Chart LED Lights vs. Incandescent Light Bulbs vs. CFLs.



Sub-metering each unit reduced residential tenants’ electrical consumption by 30%.

Electrical meters or sub-meters must be installed in commercial tenant spaces or floors over 10,000 square feet.

The deadline is January 1, 2025.

Tenants must be provided with a statement of monthly electrical usage.

This sub-meter is in a residential cooperative that was master metered for electricity and voluntarily sub-metered each residential tenant. Now the tenants can see exactly how much electricity they are using in real time.
