If you own or manage a building in New York City, Local Law 152 gas inspections should already be on your compliance calendar.
The law requires periodic inspections of gas piping systems in most covered NYC buildings, and several important parts of the process changed in 2026.
For 2026, buildings in Community Districts 4, 6, 8, 9 and 16 are in the current inspection cycle, with an inspection period running from January 1 through December 31, 2026.
There is also a major filing change this year. As of July 27, 2026, Local Law 152 certifications and related transactions are submitted through DOB NOW: Safety instead of the previous online portal.
For building owners, landlords, co-op and condo boards, and property managers, that means instructions from the first Local Law 152 inspection cycle may no longer accurately describe the process you need to follow today.
Here is what NYC property owners need to know.
What Is NYC Local Law 152?
Local Law 152 of 2016 established periodic inspection requirements for gas piping systems in most New York City buildings.
Covered gas piping systems generally must be inspected at least once every four years, with the inspection year determined by the Community District where the property is located.
The inspection must be performed by a NYC Licensed Master Plumber or a qualified individual working for an LMP in accordance with current DOB requirements.
The purpose is straightforward: identify gas leaks and potentially unsafe conditions before they become more serious problems.
For a building owner, however, compliance involves more than simply having someone look at the pipes. There are inspection, reporting, certification and, when necessary, correction requirements that have to be completed within specific timeframes.
Which Buildings Must Comply With Local Law 152?
Local Law 152 applies broadly to NYC buildings with gas piping, but there are important exemptions.
One- and two-family homes and other qualifying properties classified in Occupancy Group R-3 are generally exempt from the periodic gas piping inspection requirement. DOB also identifies certain Department of Finance building classifications that do not have to comply.
Because building classification can be more complicated than simply counting the number of apartments, owners should verify the property rather than assuming it is exempt.
DOB now provides an LL152 Gas Piping System Compliance lookup through its public portal that can tell owners whether a property is required to comply and when its applicable deadline occurs.
This is especially useful for property managers responsible for multiple NYC buildings.
Which Community Districts Are Due in 2026?
Local Law 152 uses four inspection sub-cycles.
The current schedule is:
| Community Districts | Cycle 2 Inspection Period |
|---|---|
| 1, 3 and 10 | January 1–December 31, 2024 |
| 2, 5, 7, 13 and 18 | January 1–December 31, 2025 |
| 4, 6, 8, 9 and 16 | January 1–December 31, 2026 |
| 11, 12, 14, 15 and 17 | January 1–December 31, 2027 |
Cycle 3 begins in 2028, when Community Districts 1, 3 and 10 become due again.
Your Community District is not the same thing as your borough, neighborhood or ZIP code. Two buildings relatively close to each other may have different compliance years.
If your property is located in Community District 4, 6, 8, 9 or 16, December 31, 2026 is the end of the current inspection period.
Major 2026 Change: Local Law 152 Is Now in DOB NOW: Safety
This is one of the most important changes building owners need to know about.
Beginning July 27, 2026, NYC DOB moved Local Law 152 certifications and related transactions into DOB NOW: Safety. The previous online portal is no longer used for new LL152 submissions.
The DOB NOW: Safety system now handles transactions including:
- Initial Certifications
- Certifications of Correction
- Extension Requests
- Property Verification Requests
- Inspection Notifications and cancellations
- Unsafe or Hazardous Conditions Notifications
- Civil Penalty Challenges
- Civil Penalty Waiver Requests
Property owners and managers who want to review the new process directly can read the official NYC Department of Buildings July 2026 Local Law 152 DOB NOW: Safety training presentation.
That presentation is particularly useful because it walks through the current filing process and explains how the different LL152 transactions work.
Many older online articles and property-management checklists still describe the previous submission process, so make sure any instructions you are following reflect the current DOB NOW system.
There Is Now an Advance Inspection Notification Requirement
Another important 2026 requirement occurs before the inspection takes place.
An inspection entity qualified to perform the gas piping inspection must submit an Inspection Notification to DOB at least two calendar days before performing the initial inspection.
The notification includes information about the property and the scheduled inspection.
There is currently no DOB filing fee for the Inspection Notification.
For building owners, there is a practical lesson here:
Do not wait until the final day of your compliance period to call for an inspection.
There is now a required DOB notification step before the initial inspection can take place.
Who Can Perform a Local Law 152 Inspection?
A Local Law 152 inspection is not something a handyman, general maintenance contractor or unlicensed plumber can perform for DOB compliance.
The inspection must be performed by a NYC Licensed Master Plumber (LMP) or an appropriately qualified person working for an LMP under current DOB requirements.
If you are unfamiliar with the distinction, we explain what a NYC Licensed Master Plumber is and why that license matters for gas work in more detail.
DOB recommends that building owners verify a plumber's active license before hiring them.
At Buildwise Plumbing, Joseph Siniscalchi holds NYC Licensed Master Plumber License #2638.
What Does a Local Law 152 Gas Inspection Include?
A Local Law 152 inspection is more than a quick look at the gas meter.
The inspection involves examining applicable exposed gas piping within the required inspection scope and performing the required gas leak survey.
Depending on the building, applicable areas can include:
- Gas service entry areas
- Meter and service areas
- Basements and cellars
- Boiler rooms
- Mechanical rooms
- Public hallways
- Corridors
- Common areas containing gas piping
- Accessible exposed gas piping
- Other applicable areas along the gas piping system
The inspection is intended to identify conditions such as:
- Gas leaks
- Deteriorated gas piping
- Unsafe piping conditions
- Illegal connections
- Improper installations
- Other conditions requiring correction
The purpose is not to unnecessarily open walls and ceilings throughout the building. The inspection covers the gas piping and areas required under the applicable LL152 rules.
Many of the problems discovered during an inspection develop gradually or result from previous plumbing work. Our guide to the 5 common reasons NYC buildings fail gas piping inspections explains several of the issues building owners should watch for.
Does the Plumber Have to Enter Every Apartment?
Not necessarily.
A Local Law 152 inspection does not automatically mean every apartment needs to be opened and every gas appliance inspected.
The required access depends on the building layout, the location of the gas service and the path of the piping covered by the inspection.
The Licensed Master Plumber should determine what areas need to be accessed based on the property's gas piping configuration and current inspection requirements.
For property managers and building owners, it is still a good idea to coordinate with the superintendent or building staff ahead of time so mechanical rooms, basements, meter areas and other necessary spaces are accessible when the inspector arrives.
What Happens After the Inspection?
The inspection itself begins several important compliance deadlines.
Within 30 Days: Inspection Report
The Licensed Master Plumber must provide the building owner with the required Gas Piping System Periodic Inspection Report within 30 days of the inspection.
The report documents the inspection results and identifies conditions requiring attention.
Building owners should retain this report with their compliance records.
Within 60 Days: Certification
The required Gas Piping System Periodic Inspection Certification must generally be submitted to DOB within 60 days of the inspection.
For current filings, Local Law 152 transactions are now handled through DOB NOW: Safety.
This creates an important distinction:
Completing the physical inspection is not the same thing as completing Local Law 152 compliance.
The required certification and any necessary follow-up must also be completed.
What If Problems Are Found During the Inspection?
Not every inspection finding has the same level of urgency.
Some conditions can be handled through the normal correction process. Other conditions may be considered unsafe or hazardous and require immediate action.
Conditions Requiring Correction
When the initial certification identifies conditions requiring correction, the DOB NOW filing identifies whether correction is expected within 120 days or 180 days from the inspection date.
If the initial filing identifies a 120-day correction period and additional time becomes necessary, the current system allows an extension up to the 180-day limit.
Once the conditions are corrected, the appropriate Certification of Correction must be submitted.
If your property has already been inspected and deficiencies were identified, read Failed Your Local Law 152 Gas Inspection? What Happens Next in NYC? for a more detailed explanation of the correction process.
Corrective work must comply with NYC Construction Codes, including obtaining required permits where applicable.
When an inspection uncovers leaking, deteriorated or non-compliant gas piping, Buildwise provides gas line repair and replacement services in NYC to help correct the plumbing side of the problem.
What If an Unsafe or Hazardous Gas Condition Is Found?
Unsafe or hazardous conditions are treated differently from routine correction items.
If an inspection reveals an unsafe or hazardous condition, the LMP must immediately notify the building owner, the utility supplying gas to the building and DOB as required. The owner must take immediate action to correct the condition in compliance with NYC Construction Codes.
DOB NOW: Safety also includes a dedicated Unsafe or Hazardous Conditions Notification, which can be submitted regardless of the property's current inspection cycle or sub-cycle.
A dangerous gas condition therefore does not simply wait for the normal 120- or 180-day correction period.
Depending on the problem, gas service may need to be shut down until repairs, testing, inspections and utility requirements are completed.
What If the Building Has No Gas Piping?
This is one of the areas where older Local Law 152 information can create unnecessary confusion.
If Local Law 152 otherwise applies to the property but the building does not contain a gas piping system, a certification stating that the building contains no gas piping must be submitted to DOB.
Under the current system, that certification can be made through the applicable process by an eligible Licensed Master Plumber, Registered Design Professional or utility company.
Most importantly, this certification is now a one-time requirement.
Once a building has properly certified that it contains no gas piping, DOB states that no further LL152 action is necessary unless the circumstances change.
That differs from older information suggesting that owners had to repeat the same no-gas-piping certification during every four-year inspection cycle.
What If the Building Has Gas Pipes but No Active Gas Service?
Having no active gas service is not the same thing as having no gas piping.
A building may still contain an existing gas piping system even though Con Edison or National Grid no longer supplies gas to the property.
DOB treats that as a separate situation.
For a covered property with gas piping but no current gas service and no appliances connected to the gas piping, supporting documentation is required to confirm the status of the gas service.
This distinction is important.
An owner should not claim that a property has “no gas piping” simply because the utility disconnected the service years ago.
If the pipes remain in the building, a different compliance process applies.
Special Local Law 152 Rule for New Buildings
Newer buildings have a special first-inspection rule.
DOB's July 2026 training defines a new building for LL152 purposes as a building, or portion of a building, for which DOB issued a temporary, interim or final Certificate of Occupancy on or after December 6, 2016.
These buildings are not required to have their first gas piping system inspection until the tenth year after the applicable Certificate of Occupancy was issued.
After the first inspection, the building enters the normal Local Law 152 cycle for its Community District.
DOB NOW: Safety also provides a Property Verification process that allows qualifying parties to ask DOB to determine whether a property is subject to LL152 or whether a newer building qualifies for the 10-year timing rule.
Can You Get an Extension for Local Law 152?
Yes.
If an owner cannot complete the required inspection by the end of the applicable reporting period, DOB provides a one-time 180-day extension.
Under the current DOB NOW system, an Initial Certification Extension Request may be submitted before the end of the applicable sub-cycle and provides an additional 180 days beyond that deadline.
This should not be confused with a correction extension.
A separate extension process applies when conditions identified during an inspection were initially expected to be corrected within 120 days but additional time is required up to the 180-day correction limit.
For buildings due in 2026, scheduling the inspection well before the end of December is still the better option.
What Is the Penalty for Missing Local Law 152?
DOB states that failure to submit the required Gas Piping System Periodic Inspection Certification by the applicable due date may result in a $5,000 civil penalty.
This is not simply a theoretical requirement.
DOB issued Notices of Violation in January 2026 to owners of applicable buildings that failed to submit required Cycle 2, Sub-cycle A certifications.
If a compliance issue is connected with unsafe gas piping, a utility shutoff, red tag or another gas-related violation, Buildwise also provides gas violation and red tag removal services in NYC.
What If You Already Received a Local Law 152 Violation?
The current DOB NOW: Safety system provides mechanisms for Civil Penalty Challenges and Civil Penalty Waiver Requests depending on the circumstances.
A challenge is intended for an owner who has proof that the required certification was already submitted.
DOB's July 2026 training states that a violation challenge must be submitted within 30 days from the postmark date of the violation served by DOB.
Waivers are different and may apply to specified situations when the owner can provide the required supporting documentation.
The important point is that receiving a violation does not mean the owner should guess at the solution. The correct response depends on why the violation was issued and the property's actual compliance status.
Current Local Law 152 DOB Filing Fees
The move to DOB NOW: Safety also introduced clearly defined filing fees for private owners.
Current DOB fees shown in the July 2026 training include:
| LL152 Transaction | DOB Filing Fee |
|---|---|
| Initial Certification – active gas service | $35 |
| Initial Certification – gas piping but no gas service | $480 |
| Initial Certification – no gas piping | $375 |
| Certification of Correction | $35 |
| Initial Certification Extension Request | $35 |
| Certification of Correction Extension Request | $35 |
| Inspection Notification | No fee |
| Property Verification | No fee |
| Unsafe or Hazardous Conditions Notification | No fee |
These are NYC Department of Buildings filing fees, not Buildwise inspection, repair or professional service charges.
Why You Should Not Wait Until the End of 2026
December 31 may be the end of the current inspection period for Community Districts 4, 6, 8, 9 and 16, but that does not make December the best time to start the process.
Several things can complicate an LL152 inspection:
- Difficulty accessing mechanical or meter rooms
- Existing gas leaks
- Corroded or deteriorated piping
- Illegal or undocumented gas work
- Repairs requiring permits
- Utility coordination
- Scheduling corrective work
- Building management or board approval
- Required DOB notifications
- Certification of correction
- End-of-year scheduling availability
There is also now a required advance DOB Inspection Notification before the initial inspection.
If the gas piping is in good condition, scheduling early gets the requirement out of the way.
If the inspection identifies a problem, scheduling early gives you time to correct it properly.
How Building Owners and Property Managers Should Prepare
You do not need to become a gas-code expert before your Local Law 152 inspection, but a little preparation can make the process easier.
A good starting checklist includes:
- Confirm whether the property is subject to Local Law 152.
- Confirm the Community District and applicable inspection year.
- Determine whether the property currently has active gas service.
- Identify gas service and meter locations.
- Arrange access to basements, cellars and mechanical rooms.
- Locate previous LL152 inspection records.
- Gather information about previous gas permits or violations.
- Inform the building superintendent or maintenance staff.
- Schedule early enough to allow time for corrective work if necessary.
If you manage several buildings, verify each property separately rather than assuming every building in your portfolio follows the same inspection schedule.
For management companies, facility managers and owners responsible for larger properties, Buildwise also provides commercial plumbing and gas compliance services throughout NYC.
Common Local Law 152 Mistakes
Several mistakes repeatedly cause unnecessary problems for NYC building owners.
Assuming a Small Building Is Automatically Exempt
One- and two-family homes and other qualifying R-3 properties are generally exempt, but not every small apartment or mixed-use property falls into that category.
Check the actual building classification.
Waiting Until the Deadline
If the inspection identifies a problem that requires repair, permitting or utility coordination, waiting until the end of the year leaves very little room to deal with it.
Assuming the Inspection Alone Completes Compliance
It doesn't.
The inspection is one part of the process. The appropriate certification and any required correction filings must also be completed.
Confusing “No Gas Service” With “No Gas Piping”
These are two different conditions under the Local Law 152 process.
A building may have no active utility service but still contain extensive gas piping.
Hiring Someone Who Is Not Properly Qualified
Gas compliance work is regulated in New York City.
Make sure the person responsible for the inspection is working within the current DOB licensing and qualification requirements.

Local Law 152 Frequently Asked Questions
How often is a Local Law 152 inspection required?
Covered gas piping systems generally must be inspected at least once every four years. The applicable inspection year is determined by the building's Community District.
Which Community Districts are due in 2026?
Community Districts 4, 6, 8, 9 and 16 are in the 2026 inspection period, running through December 31, 2026.
Are one- and two-family houses exempt?
Generally, yes. One- and two-family homes and other qualifying Occupancy Group R-3 properties are exempt from the periodic LL152 inspection requirement.
Does DOB need to be notified before the inspection?
Yes. The qualified inspection entity must submit an Inspection Notification at least two calendar days before the initial inspection.
How long after the inspection does the owner have to file?
The LMP must provide the inspection report within 30 days, and the required certification generally must be submitted within 60 days of the inspection.
What if repairs are needed?
Conditions requiring correction may follow a 120-day or 180-day correction timeframe, depending on the initial filing. If 120 days was originally specified, an extension may be requested up to the 180-day limit.
What if my building contains no gas piping?
A no-gas-piping certification must be submitted. Under the current process, this is a one-time certification, and no further LL152 action is necessary unless circumstances change.
What if the building has gas piping but no active gas service?
That is treated differently from a building with no gas piping. DOB requires supporting documentation concerning the discontinued gas service and the absence of connected gas appliances.
Can I request an extension?
Yes. DOB provides a one-time 180-day extension for the applicable initial inspection/certification deadline when requested within the required timeframe.
What is the penalty for missing the deadline?
Failure to submit the required certification by the applicable deadline may result in a $5,000 civil penalty.
