Everything you want to know about NYC Local Law 152- but were afraid to ask.
Everything you want to know about NYC Local Law 152 (AKA LL 152, New York City Periodic Gas Inspections).
We asked for you – so you can KEEP YOUR GAS.
How many NYC buildings are subject to Local Law 152 inspections from 2024 through 2027?
According to the NYC Department of Buildings (DOB), 279,811 buildings across the five boroughs are identified for Local Law 152 inspections during the current 4-year cycle (2024 – 2027).
The DOB provides an official spreadsheet listing every property that must comply, whether or not the building has a gas piping system. This list helps property owners confirm whether their building falls under the inspection requirement.
Click HERE to visit the DOB’s Local Law 152 page. Then scroll down and click “LL152 Properties”. The Excel file will download automatically. The most recent version is 07/27/2026.
I received a Notice of Deficiency (NOD) from the NYC Department of Buildings. What does it mean?
A Notice of Deficiency (NOD) is an alert from the NYC Department of Buildings (DOB) indicating that their records show your building did not submit a required Local Law 152 (LL152) gas piping inspection certification during the 1st cycle between 2020 and 2023.
While these notices are intended to prompt proactive compliance, they do not carry a civil penalty unless there is a failure to comply during the 2nd cycle of 2024 to 2028.
NODs were issued as follows via USPS:
09/18/2025 for inspections due by 12/31/2025 or 06/28/2026 with an extension.
10/21/2025 for inspections due by 12/31/2026 or 06/28/2027 with an extension.
01/31/2025 for inspections due by 12/31/2027 or 06/28/2028 with an extension.
For those who received an NOD for a 2027 due date, the inspection cannot be completed until 2027.
If you received an NOD for 2025 or 2026 and have not completed an inspection, feel free reach out to KeepMyGas right away. We’ll research you building and guide you as to next steps
I believe my building is a 1 or 2-family, but the NYC Department of Finance classifies it as a 3-family. How can I challenge the requirement to comply with Local Law 152?
If your building is misclassified as a 3-family by the NYC Department of Finance (DOF) and should be classified as a 1 or 2-family, then you may request an exemption from Local Law 152 gas piping inspections.
To initiate review with the NYC Department of Buildings (DOB):
- Visit DOB NOW
- Log in or create an account as a building owner (Login section is on the right side of the homepage)
- Select: DOB NOW: Safety → Compliance Filings → Gas Piping Systems
- Follow the instructions on THIS PDF and upload your supporting documents, such as your Certificate of Occupancy, HPD Image Card or Letter of No Objection.
We recommend submitting all documentation that proves the legal occupancy to support your case. (See below for instructions to locate a Certificate of Occupancy and/or HPD Image Card or a Letter of No Objection)
Note that if your site has multiple BIN numbers you will need to file for each BIN.
If your request is successful then the DOB will remove the associated BIN(s) from the list of buildings that must comply with Local Law 152.
Once this has been done you will want to communicate with the NYC Department of Finance (DOF). Call 311 and ask for the DOF and request assistance to have your tax class code revised to reflect the actual use.
The DOB Plumbing Enforcement unit has indicated they will provide further assistance, if needed. Customer service representatives are readily available to walk you through the process at 212-323-8001.
If you’d like additional assistance, feel free to contact KeepMyGas.
Instructions to locate a Certificate of Occupancy and/or HPD Image Card or a Letter of No Objection:
Certificate of Occupancy:
Click HERE and use section 1 “Search by Property” to access the BIS record for your building. (A BIN or Block and Lot are the best search option.)
On the record page click on “View Certificates of Occupancy” on the right near the top of the page. If a 1 or more Certificates of Occupancy exist, they will be listed on that page. Download the most recent PDF.
In some case there will not be a Certificates of Occupancy listed as non exists.
HPD Image Card
Click HERE and use the search function to access the HPD record for your building. (A BIN or Block and Lot are the best search option.)
On the record page scroll down and look on the left mid page for “Historical Image Cards”. If the text indicates “YES” then click on “View All” and download the PDF.
NYC DOB Letter of No Objection in lieu of a Certificate of Occupancy and/or HPD Image Card
Call your DOB Borough office and request a NYC DOB Letter of No Objection (LNO) which is a formal letter issued by the Department of Buildings confirming that DOB has no objection to a building’s existing or proposed use based on its records and applicable building and zoning requirements.
It is commonly used for older buildings that do not have a Certificate of Occupancy and/or HPD Image Card.
Once you have accessed your available documents you will review them to confirm that your building is in fact classified as a 1 or 2-Family dwelling. This will be your supporting documentation when submitting your challenge.
In the case of no documentation you may request that the DOB or the DOF send an inspector to your building to confirm 1 or 2-Family use.
Who is authorized to perform a Local Law 152 gas piping inspection in NYC?
Under Local Law 152, gas piping inspections must be conducted by either of the following:
- A NYC Licensed Master Plumber (LMP), or
- A DOB-registered Journeyman Plumber under the direct and continuing supervision of the LMP, who has successfully completed a DOB-approved 7-hour training.
These credentials must be available upon request during the inspection.
The Plumbing Foundation City of New York provides a helpful Gas Qualification Flow Chart that clearly outlines who is authorized to do what when it comes to gas work and inspections.
Click HERE to view it.
If a property owner has a building which is in a Community District that is not requiring an inspection for the current year can they have the inspection done in the current year instead of waiting until the year in which that inspection is required?
No, as per the NYC DOB, an inspection may only be completed during the calendar year that correlates with the Community District in which your building is located.
Click HERE to use our free address lookup tool to determine in which year you may have a gas piping inspection completed to comply with Local Law 152.
Will KeepMyGas look up a list of buildings for me to determine which year the inspection is due?
Yes, of course we will.
Just email Bill at bill@keepmygas.nyc and attach a PDF, Word or Spreadsheet list of your buildings. We will look up the Community District # for each address for you and circle back to you with the year due results for each building.
Or you may click HERE to use our free address lookup tool.
Can the deadline of 12/31 for each year for the requirement to have an inspection and/or to complete the correction of conditions be extended?
Building stakeholders may file for an automatic 180 day extension during any year in any cycle.
IE: You are due in 2026 and wish to extend the deadline from 12/31/2026 to 06/28/2027.
If you choose to do this, we are happy to assist or just click HERE to view a PDF with instructions to file for an automatic 180 day extension.
What is the penalty for non compliance of Local Law 152?
In the original law a penalty of $10,000 could be applied for failure to execute an inspection by the deadline for the respective community district-year and/or failure to repair conditions observed at an inspection within 120 to 180 days of the date of the original inspection.
Effective 08/11/2021 the penalty is reduced to $5,000 as per DOB Adopted Rule. Click HERE to view the Rule page.
Effective 11/18/2024 the penalty for a 3 family is reduced to $1,500 as per the DOB Adopted Rule. Click HERE to view the Rule page.
Can an owner have a visual only inspection in advance of an official Local Law 152 inspection to determine if illegal or hazardous issues exist?
An owner may hire a Licensed Master Plumber to perform a visual survey of the gas piping system prior to the Local Law 152 inspection. While on site, a Licensed Master Plumber is required to follow the established gas protocols which were put in place even prior to Local Law 152 and is required to report illegal and/or hazardous conditions. Therefore it is recommended that the complete Local Law 152 inspection be the first and only inspection to avoid the extra cost of what could have been accomplished with just the local Law 152 inspection.
Is compliance required for a building without gas service?
An “Amendment of Rules relating to Gas Piping Inspections” has been adopted and became effective 01/03/2026. Click HERE to read the adopted rules. Refer to page 4, paragraphs 2 and 3 to first determine your “no gas service” scenario.
Scenario 1 may require an Inspection* by a Licensed Master Plumber (LMP) or Registered Design Professional – Engineer or Architect (RDP)
The filing process certifying for a building that does not have gas service or any gas piping, typically built that way, is to be done on DOB NOW.
There is a filing fee of $375.
For more information, see Follow-up #8 for Local Law 152 of 2016.
*On a case by case basis, an inspection may be avoided. Contact Bill for details.
Scenario 2 An inspection by an LMP or RDP is not required.
For a building that has gas piping but is not currently supplied with gas and does not have any appliances connected to gas piping, the required paperwork can be uploaded on DOB NOW.
There is a filing fee of $480.
For more information, see Follow-up #8 for Local Law 152 of 2016.
To acquire the letter from the utility, for this scenario, you will call the gas provider for your location; either ConEd or National Grid. Indicate that you are asking for a letter provided by the utility as per §28-318.3.5 Buildings Without Active Gas Service.
National Grid and ConEd may require a site visit and in some cases, require the gas service to be cut and capped in the street.
In both cases you often must be persistent and call several times to reach a customer service representative that is familiar with your request.
ConEd – 800-643-1289
National Grid – 718-643-4050
For more information, see Follow-up #8 for Local Law 152 of 2016.
We have assisted many stakeholders with these scenarios and are happy to talk with you to answer any additional questions you may have.
What if there is more than one building, each with its own DOB Building Identification Number (aka BIN), on a single tax lot and there is a mixture of buildings with gas piping and buildings without gas piping?
Each building on 1 tax lot that has a unique BIN (Building Information Number) requires a separate inspection and filing to be associated with that unique BIN.
This would include any and all out buildings, IE: Garages and/or Sheds that have a unique BIN.
Each filing would be completed in a way that correlates with each building’s gas piping service status; a building with live gas service and usage, a building with gas piping but no gas service/usage or a building with no gas piping and no gas service.
There are many unique scenarios that can exist regarding more that 1 BIN on a tax lot and at times it may be appropriate to consolidate the BINs to 1 BIN for the entire tax lot.
We recommend that you contact the Local Law 152 Department at the NYC DOB and describe your situation for guidance on how to proceed.
You may reach them at 212-323-8001 and/or LL152of16@buildings.nyc.gov
You can also visit, call or email the appropriate City Planning Department for you Borough and describe your situation for guidance on how to proceed.
Click HERE for the City Planning main we page to obtain the contact information for each Borough.
Are new buildings exempt from Local Law 152?
The initial inspection for a “New Building” with a gas piping system must be performed in the 10th year following DOB approval for occupancy, as evidenced by the Certificate of Occupancy (CO) or Temporary Certificate of Occupancy (TCO) issued after December 6, 2016. The 10-year period is calculated from the date of the earliest CO or TCO. After this initial inspection, the building will then follow the standard inspection cycle, even if the next required inspection occurs in less than four years.
If the earliest Certificate of Occupancy (CO) or Temporary Certificate of Occupancy (TCO) was issued on or before December 6, 2016, the building is not eligible for the 10-year exemption and must comply with the standard inspection cycle.
See page 2 paragraph 5 of §103-10 Periodic Inspection of Gas Piping Systems.
Click HERE to check in which year your inspection is due.
What type of insurance policies should a Local Law 152 inspector have?
At a minimum, a Licensed Master Plumber (LMP) should have a General Liability policy.
It is recommended that they would additionally have a Professional Liability Policy also know as Errors and Omissions Insurance. The Professional Liability Policy is the only policy that covers the LMP for an error or omission with regard to information provided and performance of the inspection.
This can be verified by asking the inspector to show proof of General Liability and Professional Liability insurance by providing you with a Certificate of Insurance (COI) that will list all insurance in place for the LMP.
Which portable combustible gas detector is approved for use when performing a Local Law 152 inspection?
The popular device that is used when performing a Local Law 152 inspection is the LMP200. This device can only be purchased by a Licensed Master Plumber (LMP). The serial number of all purchased devices are registered to the license number of the LMP. This device is only available through City Calibration Centers.
To view a list of other approved devices on the New York State Department of Public Service website, click HERE.
Is commercial space in a building required to be inspected?
As of February 22, 2026, through Local Law 142, gas piping inspections now include commercial tenant spaces within a building that has exposed gas piping and/or appliances or equipment connected to gas piping.
Other than as required to provide access to the point of entry of gas piping – dwelling units, as defined by section 202 of the New York city building code, are not be required to be inspected.
History of Local Law 142
On 09/25/2025 Proposed Int. No. 429-A – 91825 was passed by the NY City Council with a vote of 47 to 1. Int. No. 429-A – 91825 was originally introduced 02/28/2024. The first hearing was 10/16/2024 and on 10/25/2025 is was enacted as Local Law 142.
The law became effective on February 22, 2026 and amends the administrative code of the city of New York and the fuel gas code in relation to the periodic inspections of gas piping systems, ordinary plumbing work, reestablishing the plumbing and fire suppression piping contractor license board, piping systems, emergency work, fire suppression piping work, and seizure.
Is it permissible for the Licensed Master Plumber (LMP) to correct conditions at the time of the inspection?
The DOB indicated that all work on gas piping is subject to the requirements of the Fuel Gas Code and must be performed in accordance with the requirements of the Administrative Code – including those for qualifications, permits, and inspections. Provided that the corrections are performed in accordance with the code, there is no prohibition that the licensed master plumber cannot identify and also correct conditions while onsite.
Under what conditions is the Licensed Master Plumber (LMP) required to make an immediate notification and to whom during an inspection?
In the event of any gas leak or immediately hazardous condition, standard notifications requirements apply.
To report an immediate hazard, the LMP is to follow the established protocols which were put in place even prior to Local Law 152 and will contact the building owner/manager, the governing utility for the location and the Plumbing Enforcement Inspections unit at the DOB.
Local Law 153 also requires building owners to advise tenants what action to take when they suspect that a gas leak has occurred.
Tenants should receive a Suspected Gas Leak Notice describing the procedures to be followed when a gas leak is suspected with the first lease or first lease renewal from the property owner. Property owners may also choose to post the Combined Notice for smoke detectors/carbon monoxide detectors and gas leak notice.

What are the options for a building owner when the building owner does not agree with the items that require repair or replacement that are observed by the Local Law 152 inspector?
Within 30 days of a Local Law 152 inspection, the LMP entity that performed the inspection must provide to the building owner an Inspection Report communicating the results of the inspection.
If a building owner does not agree with the items observed by the Local Law 152 inspector that are listed on the Inspection Report which require repair or replacement then the owner can ask the LMP entity that performed the inspection contact the DOB for guidance.
The DOB reserves the right to review the details of the inspection on a case by case basis. This may require a follow up visit from the DOB and the utility company. If the DOB finds that items originally indicated do not require correction then the LMP may update the Inspection Report and then file appropriately on DOB NOW: Safety.
Is there a place in the record of the building on the DOB website in either DOB BIS and/or DOB NOW where one can see a record of a LL152 compliance filing submitted to the DOB for properties that have been inspected?
YES & NO.
For filings on or before July 24th, 2026, the filing record is not publicly accessible through a DOB look up function.
To request verification of a Local Law 152 filing that occurred on or before July 24th, 2026, you can email LL152of16@buildings.nyc.gov with the address, block, lot and BIN of the building in question and ask if a filing has been completed and if so, when.
Always feel free to CONTACT KeepMyGas if you need a lookup of the block, lot and BIN of a building.
For filings on or after July 27th, 2026, filing data is publicly accessible through a DOB NOW look up function.
All completed LL152 compliance filings are now publicly visible by searching for the building on the DOB NOW public portal by either Address, Borough – Block – Lot or BIN.
Once you are at the building record go to:
Jobs/Occupancy/Compliance Filings – SAFETY: Compliance Filings, Compliance Type: and choose Gas Piping Systems.
The record for any LL152 compliance filing that occurred on or after 07/27/2026 will be listed.
Click on the View Icon and a pop up will appear to access to all the information.
As of July 27th, 2026 all LL152 filings will be completed using DOB NOW: Safety.
Click HERE to read our article regarding the migration of LL152 filings to DOB NOW: Safety.
Does the DOB require the inspection entity to provide advanced notice?
Yes. Under updated NYC Department of Buildings (DOB) requirements, the inspection entity performing a Local Law 152 inspection must provide advance notice to the DOB before the inspection takes place, at least 2 days prior.
The notification is completed in DOB NOW: Safety as the 1st step of the LL152 filing process.
Click HERE for a PDF of the instructions to file this notification.
If a jurisdictional piping inspection has already been completed by Consolidated Edison (ConEd) or National Grid do I still need the Local Law 152 inspection?
In addition to the Local Law 152 inspection that is performed by a Licensed Master Plumber, Consolidated Edison (ConEd) and National Grid will continue to complete the New York State required Service Line Inspections of jurisdictional piping which is the piping and apertures from the point of entry of the gas service to the outlet of the gas meter.
These inspections do not take the place of the Local Law 152 inspection that is performed by a Licensed Master Plumber.
Please click below to see more information on New York State required Service Line Inspections of jurisdictional piping by the utility. To be on the safe side, always communicate directly with the utility to arrange this inspection so you are certain that it is being done by an authorized employee or representative of the utility company.

Where can I go to see the most current actions that the NY City Council has taken regarding Local Law 152?
Is there an official NYC Buildings (AKA Department of Buildings DOB) web page that has a Step-by-Step Guide to Complying with Local Law 152 of 2016 Periodic Inspections of Gas Piping Systems?
Yes there is!
NYC Buildings, AKA The NYC Department of Buildings (DOB) has set up a special page for homeowners to help them navigate the requirements of LL152 and coach you on the diligence to complete when you hire a Licensed Master Plumber to Inspect Your Building’s Gas Piping System.
You may access that page here:

What is Local Law 157 and does it relate to Local Law 152?
While Local Law 152 is our primary focus, we do stay up to speed on Local Law 157 to better support our clients.
As we know, Local Law 152 is the periodic inspection of gas piping systems and the law is administered by the NYC Department of Buildings (DOB).
On the other hand, Local Law 157 requires the installation of gas detectors in specific buildings in the room in which a gas appliance is operated and the law is administered by the NYC Department of Housing Preservation and Development (HPD).
On June 30th, 2025 NY City Council passed Int 1281-2025 which postpones the current mandate and now provides that natural gas alarms will be required one year after the department of buildings determines that natural gas alarms are sufficiently available and affordable, but no earlier than January 1, 2027.
On June 15th, 2026 the DOB published a Service Notice confirming that the deadline to install natural gas alarms is January 1, 2027.
