LL152 of 2016 Step-by-Step Compliance Guide

STEP 1: Determine if the Gas Piping System Inspection Requirement Applies to Your Building

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 for your building. If no Certificate of Occupancy for your building is available, you may instead refer to the Department of Finance’s Building Classification. 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.

To find the Certificate of Occupancy or to identify your the Department of Finance Building Classification for your building, please visit DOB’s Building Information System (BIS) and search using your the address of your building.

STEP 2: Determine Whether Your Building Contains Gas Piping

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), 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 a Licensed Master Plumber. Please proceed to STEP 3.

STEP 3: Hire an Licensed Master Plumber to Inspect the Gas Piping System in Your Building

Licensed Master Plumbers (LMPs) are licensed by DOB to perform plumbing work in New York City. DOB encourages anyone hiring a Licensed Master Plumber to check both their current license status and disciplinary and voluntary surrender records.

Before hiring an LMP:

  • Use the License Search tool to make sure the LMP'sr license is active. The tool allows you to search a licensee by name, business name, or license number.
  • Review the disciplinary actions taken against a licensee by DOB or voluntary surrender records by using the Know Your Construction Professional tool.

STEP 4: LMP Must Submit a Gas Piping System Periodic Inspection Report to the Building Owner Within 30 Days of Inspection

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.

STEP 5: Building Owner Must Submit Gas Piping System Periodic Inspection Certification to DOB Within 60 Days of Inspection

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 to DOB using this online portal.

  • If the Gas Piping System Periodic Inspection Certification submitted to DOB indicates that conditions requiring correction were identified during the gas piping system inspection, you must submit to DOB, within 120 days of the inspection, a Gas Piping System Periodic Inspection Certification signed and sealed by the Licensed Master Plumber who conducted the inspection, stating that the conditions have been corrected.
  • If the Gas Piping System Inspection Certification submitted to DOB indicated that additional time was needed to correct the condition(s) identified during the gas piping system inspection, you must submit to DOB, within 180 days of the inspection, a Gas Piping System Periodic Inspection Certification signed and sealed by the Licensed Master Plumber who conducted the inspection, stating that the conditions have been corrected.
  • Correction of conditions identified during a gas piping system inspection must be performed in compliance with the New York City Construction Codes, including obtaining any required work permits.

Failure to file a Gas Piping System Periodic Inspection Certification by the applicable due date may result in a civil penalty of $10,000.
