LL152 inspections require the qualified gas piping system inspector to look for evidence of excessive atmospheric corrosion or piping deterioration; illegal connections; non-code compliant installations, as well as the following conditions which must be reported to the owner, utility company, and DOB immediately: gas leaks; illegal connections; non-code compliant installations; and any condition defined as “Class A” by the utility company, which is considered an imminently dangerous condition. 

Within 60 days of the inspection, the OWNER must submit to the Department a Gas Piping System Periodic Inspection Certification (GPS2) signed and sealed by the LMP who conducted or supervised the inspection. The GPS2 submission is to be completed by the Building Owner on the Department’s GPS2 submission web portal.

Failure of an owner to file an Inspection Certification before the applicable due date may result in a civil penalty of $10,000.00. Building owners are required to keep on file for ten years all reports and certifications and make them available to the DOB upon request.

If the inspections reveal any hazards on your gas piping system, the inspector is required to notify the building owner, the utility company providing gas service to the building, and to DOB. These hazards can be defined as:

• Gas leaks
• Evidence of illegal connections or non-code compliant installations, or;
• Any other conditions, which if verified by a utility company would constitute a class A condition as described in part 261 of title 16 of the New York Codes, Rules and Regulations, or constitutes an imminently dangerous condition.

The building owner must take immediate action to correct these conditions per NYC Construction Code.

Owners of buildings that do not contain gas piping must submit to the Department a Gas Piping System Periodic Inspection Certification, signed and sealed by a registered design professional, stating that such building contains no gas piping.
