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), 286,945 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
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.
In September 2025, the DOB began issuing NODs to buildings due for inspection in 2025 and in late October 2025, NODs were also issued to buildings due in 2026. (For those who received an NOD for a 2026 due date, the inspection cannot be completed until 2026)
If you received an NOD, feel free reach out to KeepMyGas right away. We’ll verify your building’s inspection year due and ensure your inspection and certification are completed on time.
I believe my building is a 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?
You may request an exemption from Local Law 152 gas piping inspections if your building is misclassified as a 3-family by the NYC Department of Finance (DOF), but your Certificate of Occupancy or HPD Historical Image Card shows it is a 2-family and it is used as a 2-family.
To initiate a challenge 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 → Violations → Challenge Request → Gas Piping
-
Follow the on-screen instructions and upload supporting documents, such as your Certificate of Occupancy or HPD Image Card.
We recommend submitting all documentation that proves the legal occupancy to support your case. (See below for instructions to locate your Certificate of Occupancy and/or HPD Image Card)
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 212-393-2550.
If you’d like additional assistance, feel free to contact KeepMyGas.
Instructions to locate your Certificate of Occupancy and/or HPD Image Card:
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 Certificates of Occupancy exists it will be listed on that page. In some cases multiple listings will appear. 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.
Once you have accessed either or both documents you will review them to confirm that your building is in fact classified as a 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 send an inspector to your building to confirm 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 qualified technician who:
- Has at least 5 years of experience in gas work.
- Is employed by an LMP.
- Has successfully completed a DOB-approved 7-hour training.
- Has passed a written and practical knowledge check exam.
Starting July 1, 2025, any technician (non-LMP) performing inspections must have their training credentials verified and uploaded to the DOB’s official Worker Wallet system.
These credentials must be available upon request during the inspection.
LMPs themselves are not required to take the training, but must be able to present their LMP license to verify their qualification.
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?
For 2020 and 2021 the NY City Council legislatively extended the deadlines from 12/31/2020 to 06/30/2021 and from 12/31/21 to 06/30/2022.
IE: You are due in 2025 and wish to extend the deadline to from 12/31/2025 to 06/30/2026.
If you choose to do this, we are happy to assist with no fee to do so. Click HERE to view the Service Notice

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.
The law originally indicated that only a Registered Design Professional (RDP); Professional Engineer (PE) or Registered Architect (RA) can complete an inspection on buildings without gas piping to certify that there is no gas piping. May a Licensed Master Plumber (LMP) also perform an inspection on buildings without gas piping to certify that there is no gas piping?
Originally, as per LL152, only a design professional can certify that a building does not have a gas system.
On 10/21/2021 The NY City Council amended LL152 to additionally allow a Licensed Master Plumber (LMP) may also perform an inspection on buildings without gas piping to certify that there is no gas piping.

On Page 2 of DOB Service Notice Follow-Up #5 there are instructions on how to comply when a building contains gas piping, but the building is not currently supplied with gas and has no appliances connected to the gas piping. On January 13th, 2023 the DOB published a Buildings News Update that provides more information on Gas Piping Inspection Reports and a link to “More Info on Periodic Gas Piping System Inspections”. See STEP 6: on that page for contact info to obtain the signed statement from the utility company referred to on page 2 of DOB Service Notice, Follow-Up #5.

IMPORTANT UPDATE Oct/Nov 2025
Click HERE to view the “Amendment of Rules relating to Gas Piping Inspections” that
will impact how to certify in the case of no gas service.
As of today, these rules are in a status of proposed and yet to be adopted.
In the meantime, owners of buildings without gas service should continue to follow
the instructions from the December 2021 DOB Service Notice, Follow-Up #5.
Click HERE to view that Service Notice.
************************************************************************
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?
As per the DOB each building with a unique BIN (Building Information Number requires a separate inspection and filing of the paperwork to be associated with that unique BIN (Building Information Number). This would include any and all out buildings, IE: Garages and/or Sheds that have a unique BIN.
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.
Are individual tenant spaces such as apartments, leased offices and leased retail space inspected?
The DOB interprets the City Council’s intent that the inspection include spaces not subject to tenant control or access restriction. As stipulated in the law, the inspection scope ends at individual tenant space – regardless of whether that tenant space is occupied as an apartment, an office or leased retail space as in a restaurant. Also any gas meters in tenant controlled or access restricted space are not inspected. An example would be residential apartments that have the gas meter in the apartment.
However if the point of entry of the gas service or exposed gas piping or building gas equipment is in a commercial tenant controlled space then access to that area is required to perform a complete inspection. In addition if a commercial building is owner occupied then access to that area is required to perform a complete inspection as well.

Sub note- Click HERE to review the Proposed Amendment of DOB Rules relating to Gas Piping Inspections. A Virtual Public Hearing was held 10/27/2025 and as of 11:59pm 10/27/2025 the opportunity to submit comments is closed. This proposed Amendment of Rules is not intended to address any of the changes to Local Law 152 Gas Piping Inspections as a result of the 9/25/2025 passing of Int 0429-2024.
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.
Is there paperwork and filing involved and if so, who is responsible?
In the case of a building with gas piping the Licensed Master Plumber (LMP) will complete a GPS-1 and a GPS-2, apply their embossed hard seal and wet signature to the originals and deliver those to the owner within 30 days of the inspection date.
While per the law it is the building owner’s responsibility to scan the originals and electronically submit the GPS-2 to the DOB using this PORTAL. The LMP or other authorized building owner representative may, on the building owner’s behalf, electronically submit the GPS-2 to the DOB using this PORTAL. The filing must be completed within 60 days of the date of inspection.
In the case of a building without gas piping a Registered Design Professional (RDP) or Licensed Master Plumber (LMP) will complete a GPS-2, The RDP or LMP will apply their seal and signature and deliver that to the owner within 30 days of the inspection date. While it is the building owner’s responsibility to scan the originals and electronically submit the GPS-2 to the DOB using this PORTAL. The RDP. LMP or other authorized building owner representative may, on the building owner’s behalf, electronically submit the GPS-2 to the DOB using this PORTAL. The filing must be completed within 60 days of the date of inspection.
The upload to the portal of the GPS-2 by the owner or an authorized representative satisfies all filing requirements. There is nothing else for the owner to do except retain the hardcopy or electronic scan for 10 years. Either a hardcopy or an electronic scan is acceptable provided that all the necessary information is included and all the required signatures are provided.
Currently there is no fee for this filing however please see the update below regarding filing fees and other changes that will impact how filing will be done.

will impact filing fees.
As of today, these rules are in a status of proposed and yet to be adopted.
What additional paperwork is required in the case where the original inspection resulted in conditions that required correction/repair?
This would occur only in a building with gas piping.
Another GPS-1 is not required and the correcting Licensed Master Plumber (LMP) will complete a new GPS-2 that certifies the conditions have been corrected, apply their embossed hard seal and wet signature to the original and deliver this to the owner within 30 days of the correction date.
While it is the building owner’s responsibility to scan the original and electronically submit the new GPS-2 to the DOB using this PORTAL The LMP or other authorized building owner representative may, on the building owner’s behalf, electronically submit the new GPS-2 to the DOB using this PORTAL.
NOTE: If a LMP other than the original inspecting LMP corrects the required conditions then another Local Law 152 Inspection is required. This as per Q14/A14 on page 7 of the most recent NYC DOB FAQs. Click HERE for that PDF.
The upload to the portal of the final GPS-2 by the owner or an authorized representative satisfies all filing requirements.

IMPORTANT UPDATE Oct/Nov 2025
Click HERE to view the “Amendment of Rules relating to Gas Piping Inspections” that
will impact filing fees.
As of today, these rules are in a status of proposed and yet to be adopted.
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.
Click HERE to access the Housing Quality/Safety/Gas page on the NYC Housing Preservation & Development website.
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 company that performed the inspection must provide to the building owner a GPS Periodic Inspection Report (GPS-1) showing the results of the inspection and a GPS Periodic Inspection Certification (GPS-2). If a building owner does not agree with the items observed by the Local Law 152 inspector that are listed on the GPS-1 that require repair or replacement then the owner can email the GPS-1 to the DOB dedicated Local Law 152 email of LL152of16@buildings.nyc.gov
DOB has indicated that they will review the findings listed on the GPS-1 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 GPS-1 and GPS-2 as appropriate.
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 the GPS-2 submitted to the DOB PORTAL by the Licensed Master Plumber (LMP) or the Registered Design Professional (RDP) for properties that have been inspected?
The DOB indicated that filed GPS-2 forms will not be publicly accessible through a DOB look up function however the DOB updates the internal record of GPS-2 filings every Monday.
To request verification of a Local Law 152 GPS-2 filing, you can email LL152of16@buildings.nyc.gov with the address, block, lot and BIN of the building in question and ask if a GPS-2 form has been filed.
Always feel free to CONTACT KeepMyGas if you need a lookup of the block, lot and BIN of a building.
IMPORTANT UPDATE Oct/Nov 2025
Click HERE to view the “Amendment of Rules relating to Gas Piping Inspections” that
will impact the procedure for filing a certification of the completion of a Local Law 152 inspection.
As of today, these rules are in a status of proposed and yet to be adopted.
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.
In addition, the GPS-2 form that is part of the paperwork for a Local Law 152 inspection is only filed with NYC Buildings (DOB) and not with Consolidated Edison (ConEd) or National Grid.
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.

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 3oth, 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.
