Does LL152 apply to me?

Who exactly does LL152 apply to?

All buildings that are 10 years old or older with three or more family units.

LL152 also applies to all commercial buildings or buildings that have commercial units that are 10 years or older (regardless of size). 

For example, if you have a single-family unit on the second floor, with commercial space below LL152 applies (even though it's only two units).

Here's another example: If you have a building, with three separate units, and three separate groups residing in the building, LL152 applies (even if it's only one floor).

If you’re unsure of your property classification, you can find your building’s occupancy group on the Certificate of Occupancy.

Buildings less than 10 years old are exempt and will need a LL152 inspection 10 years after their first gas permit was issued.

What does a Local Law 152 inspection involve?

Local Law 152 Gas Inspection Details

Within 30 days of each inspection, the LMP must complete and deliver a GPS1 Form that details all results for the building owner or board to review. This report will include a list of conditions requiring correction. Examples may include frayed or worn piping components that affect safe and reliable operation, non-code compliant installations, illegal connections, the detection of combustible gas, and any other conditions determined to be unsafe by the LMP.  

The LMP will also verify that portable combustible gas indicators and detection devices are present in the building.

Click here for a list of acceptable devices approved by the New York State Department of Public Service.
The building owner must submit the inspection certification (GPS2) form to the DOB within 60 days of the inspection date. 
Late submissions will require a new inspection. Therefore, in order to make sure you do not miss your inspection date, Quix Plumbing Service will submit the GPS2 form to the DOB on your behalf (through their online portal) at no additional fee and we will inform you once the process is completed.

What must be inspected for Local Law 152?

Local Law 152 - What is inspected?

LL152 requires all exposed gas piping from point of entry of gas piping into the building, including building services meters, and all gas piping in public spaces, hallways, corridors, and mechanical and boiler rooms. 

This does not include gas piping inside of apartments, but the doorway to the apartment must be checked to make sure there is not a gas leak within. 

What's considered unsafe or hazardous?

Local Law 152 Gas Inspection Details | Hazards

Examples of unsafe/hazardous conditions include:

  • The detection of combustible gas in surrounding air.
  • Evidence of illegal connections or non-code compliant installations.
  • Excessive piping corrosion or cracks.
  • Any immediate hazard requiring the operator to shut off the gas and lock the meter.

What's the difference between hazardous and deficient conditions?

 Deficient  vs Hazardous

In the event that deficient, but not immediately unsafe or hazardous, conditions are identified by the LMP, the building has up to 120 days to correct all deficient conditions, complete another round of inspections to certify any repairs, and file the inspection reports with the DOB. 

If additional time is needed to correct deficient condition, a building owner can petition the DOB for a 60-day extension.

What happens if the utility company shuts off my gas?

Gas Leaks and Hazardous or abnormal operating conditions

A Licensed Master Plumber must make the required repairs and subsequently 

  • File for a permit with the DOB
  • Pressure test the system to find any leaks.
  • Make required repairs.
  • Pressure test the system to confirm system integrity after repairs.
  • Arrange for and be present at a DOB physical inspection which will include a pressure test.
  • Obtain nyc DOB gas authorization, complete any required utility paperwork, and arrange for gas turn-on.
Does the plumber who identifies hazardous conditions during an inspection need to be the plumber who makes the repairs?

The Same LMP Has To Perform All Inspections

You can use any properly qualified plumber to make the repairs. 

However, the repairs must be certified by the plumber who performed the original inspection.
