To determine which Community District your building is in, please visit the NYC Department of City Planning’s website and search the address of your building. Once you determine your Community District and applicable inspection deadline from the schedule above, use the following step-by-step guide to comply with Local Law 152 of 2016 Periodic Inspections of Gas Piping Systems.
This inspection requirement applies to all buildings, except to one- and two-family homes, and other buildings classified in occupancy group R-3. If the inspection requirement does not apply to your building based on its occupancy group classification, no further action is necessary.
To determine the occupancy group classification for your building, please refer to the Certificate of Occupancy (CO) for your building. Follow the instructions on DOB’s website to search for the CO for your building.
If no CO for your building is available, you may instead refer to the Department of Finance’s Building Classification. To identify the Department of Finance Building Classification for your building, enter the address in the Buildings Information System (BIS). If your building is classified under the following classification codes, you do not need to comply with this inspection requirement: A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, B1, B2, B3, B9, M3, M4, or N2.
If your building does not contain gas piping, a Gas Piping System Periodic Inspection Certification, signed and sealed by a Registered Design Professional (a New York State licensed professional engineer or registered architect) or a Licensed Master Plumber, stating that such building contains no gas piping must be submitted to DOB. No further action is necessary.
If your building does contain gas piping, the gas piping system must be inspected by an LMP or a qualified individual working for an LMP.
LMPs are licensed by DOB to perform plumbing work in New York City. DOB encourages anyone hiring an LMP to check both their current license status and disciplinary and voluntary surrender records.
Before hiring an LMP:
Within 30 days of the inspection, the LMP you hired must provide you with a Gas Piping System Periodic Inspection Report showing the results of the inspection.
If an inspection reveals any unsafe or hazardous condition(s), the LMP must immediately notify you, the utility providing gas service to your building, and DOB. You must take immediate action to correct the unsafe or hazardous condition(s) in compliance with the NYC Construction Codes, including obtaining any required work permits.
Within 60 days of the inspection, you must submit a Gas Piping System Periodic Inspection Certification signed and sealed by the Licensed Master Plumber who conducted or supervised the inspection using DOB's using online portal.
Failure to file a Gas Piping System Periodic Inspection Certification by the applicable due date may result in a civil penalty of $10,000.
