Gas Piping Inspection - Buildings™

Gas piping systems in all buildings, except for one- and two-family homes, and other buildings classified in Occupancy Group R-3, must be inspected by a Licensed Master Plumber (LMP), or a qualified individual working for an LMP. Gas piping systems must be inspected at least once every four years according to the schedule below.

• and no later than December 31 within every fourth calendar year thereafter

NOTE: The deadline for buildings in Community Districts 2, 5, 7, 13, and 18 in all boroughs has been extended! These buildings are not required to submit Gas Piping System Periodic Inspection Certifications until June 30, 2022. Please see additional information regarding this extension.

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.

Local Law 152 of 2016 Step-by-Step Compliance Guide

STEP 1: Determine if your building is required to comply with Local Law 152 of 2016.

LL152 of 2016 applies to all buildings except one- and two-family homes and other buildings classified in occupancy group R-3. If your building is classified under the following classification codes, you do not need to comply with LL152 of 2016: A0, A1, A2, A3, A4, A5, A6, A7, A8, A9, B1, B2, B3, B9, M3, M4, or N2.

The occupancy group classification for your building is listed on the Certificate of Occupancy (CO) for your building. To find the CO for your building, follow the instructions on DOB’s website. If no CO for your building is available, look for the NYC Department of Finance’s Building Classification on the building’s Property Profile in the Buildings Information System (BIS).

STEP 2: If LL152 of 2016 applies to your building but the building does not contain 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) or a Licensed Master Plumber, stating that such building contains no gas piping must be submitted to DOB. No further action is necessary.

STEP 3: If LL152 of 2016 applies to your building, the building contains gas piping, and the building is currently supplied with gas

Hire a Licensed Master Plumber (LMP) to Inspect the Gas Piping System in Your Building. 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:

- Use the License Search tool to make sure the LMP's 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 Home page 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: 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 using DOB's using 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.
