Local Law 152 Gas Piping Inspections in NYC

Local Law 152 requires most NYC buildings — with one- and two-family homes among the exemptions — to have their gas piping inspected by a Licensed Master Plumber on a recurring four-year cycle, then certify the result to DOB.

The City doesn't send an inspector — you hire the Licensed Master Plumber. Austin performs the inspection, delivers your report, supports the DOB NOW certification, and handles any corrective work ourselves. One call closes the loop.

When is your LL152 inspection due? Check your address

Due dates run by community district, not borough. Enter the address to see the recorded district, sub-cycle, and cycle year — then answer a few questions and get your next step.

  1. 1Address
  2. 2Situation
  3. 3Plan

Pick a match from the list — we never choose a property for you. Your address is used only for this lookup; it is not added to the URL, contact links, analytics, or storage.

Know your community district? Enter it directly

Use this when the address search can't find your building. Search by neighborhood, or pick the borough and district directly. A manual result can't verify BBL, BIN, or building class — confirm the exact district with NYC Planning if you're unsure.

Matching neighborhoods appear as buttons after this field. Use Tab to review them.

Not sure which district is official for the tax lot? Use the NYC Planning community profile lookup.

The address match comes from NYC GeoSearch/PAD; PLUTO supplies the public district and building-class fields. Official DOB records, site conditions, and utility records control where they differ.

The lookup and the questions never ask for owner or taxpayer information, and this tool stores nothing. Requesting a callback is different: that sends your name, phone, and the property details and answers on this page to Austin so we can call you back.

Why the address matters
DOB assigns LL152 filing windows by community district, so the property match determines the cycle shown.
What the lookup verifies
The selected NYC match, public BBL, BIN and building class, community district, sub-cycle, and assigned cycle year.
What it cannot verify
Physical gas piping, current utility service, an accepted filing, a legal exemption, or a resolved violation.

The law, in plain English

What is Local Law 152?

What the law requires, who has to comply, and what we inspect when you hire us.

The rule in one paragraph

Local Law 152 of 2016 puts every covered NYC building on a recurring gas-piping inspection schedule. You hire a Licensed Master Plumber; the LMP inspects the exposed gas piping, gives you the report, and backs the certification you file with DOB. Which year you’re due depends on your community district — not your borough.

Who has to comply

Most multifamily and commercial buildings are covered. DOB excludes one- and two-family homes and other buildings classified in Occupancy Group R-3, and publishes further classifications that do not need to comply. Unit count, borough, and active gas service alone don’t settle it — when in doubt, check the current classification and DOB record for the property.

What we inspect

Exposed gas piping from the point of entry up to tenant spaces, plus public areas, hallways, corridors, and accessible boiler and mechanical rooms. We check for excessive atmospheric corrosion, illegal connections, and non-code-compliant conditions, and run a leak survey. Piping and appliances inside tenant spaces stay outside this periodic scope.

The fastest way to find out where your building stands is to check the address. District, cycle year, and a concrete next step — in about a minute.

Check my building

How the inspection works, start to finish

Five milestones, each with a clock attached. Miss one and the building drifts toward a civil penalty; hit them in order and LL152 is a routine line item.

  1. At least 2 days before

    DOB is notified before the visit

    The inspection entity must notify DOB at least two days before the inspection. We handle that notice when you book with us.

  2. Inspection day

    We perform the inspection

    Austin walks the building and inspects the exposed gas piping across the full scope described above — entry point to tenant spaces, common and mechanical areas — and runs the leak survey. (The rule also allows a DOB-registered journeyman who completed approved training, working under LMP supervision.)

  3. Within 30 days

    You receive the GPS1 report

    We provide the Gas Piping System Periodic Inspection Report — the GPS1 — to you within 30 days of the inspection. This is your record of the findings; it is not the DOB filing.

  4. Within 60 days

    You certify the result to DOB

    You file the certification — formally, the LMP-backed gas piping system periodic inspection certification — within 60 days of the inspection. Beginning July 27, 2026, it is submitted in DOB NOW: Safety, and the paper GPS2 is no longer required for new submissions.

  5. 120 or 180 days

    Anything that needs fixing is repaired and certified

    A finding doesn’t end the process — it starts a second clock: the condition gets corrected and a correction certification is filed with DOB on the deadline the finding sets. The details, including the immediate path for unsafe conditions, are in the failed-inspection section below.

DOB's current gas-piping inspection guidance (opens in a new tab) controls the schedule, applicability, certification steps, and civil-penalty posture.

If something is found

What happens if your building fails: corrections and penalties

If our inspection reveals unsafe or non-compliant conditions, we document the result. What happens next depends on the finding:

Unsafe conditions get an immediate path

Unsafe or hazardous conditions require immediate notification to the owner, DOB, and the serving utility, plus immediate corrective action under the applicable code and permit requirements.

Corrections run on a clock

The initial certification remains due within 60 days. When conditions requiring correction are reported, DOB describes a correction certification within 120 days, or within 180 days when the initial certification states that additional time is needed.

Missed filings risk a civil penalty

DOB says failure to file the required certification by the applicable due date may result in a civil penalty. Use the current DOB NOW record and official guidance to determine what is outstanding for your building.

This is where having one company matters. An inspection-only shop hands you the finding and leaves you to find a contractor. Austin performs the inspection and the corrective gas-piping work, and coordinates the required permit, test, reinspection, certification, or utility steps. The exact path comes from the finding and the property record — an LL152 condition doesn't automatically require every one of those steps, and we don't invent steps your building doesn't need.

Owner guide

How to prepare for LL152 inspection day

Most repeat visits come from access, not from the piping. A little preparation is the single biggest time and cost saver.

Arrange access before we arrive

Under DOB's current FAQ, an inspection that cannot reach every required area must not be certified as complete and has to be repeated — so line this up first:

  • Building contact and keys. Arrange an on-site building contact and working keys for required common and service areas, including boiler or mechanical rooms and areas with exposed gas piping.
  • Roof and gas-piping access. Confirm that rooftops and the areas gas piping runs through are reachable and not locked, blocked, or otherwise inaccessible.
  • Incomplete access means a repeat inspection. If full required access is unavailable, the inspection cannot be certified as complete and must be repeated. Incomplete access alone is not automatically an emergency.

Have these documents ready

  • Property and gas-service facts. Have the exact property address and borough ready, plus what is known about active service, a shutoff or discontinuance, meters, appliances, and visible gas piping. Unknowns should be reviewed, not guessed.
  • Prior inspection and official records. Gather any inspection report, certification or DOB NOW confirmation, Notice of Deficiency, violation, extension, utility shutoff notice, or red tag.
  • Classification record. Have the Certificate of Occupancy or current DOB/DOF classification available when it is unclear whether Local Law 152 applies.

Tenant spaces and appliances stay outside this periodic-inspection scope. If anything is unknown, have it reviewed rather than guessed — the address lookup above routes uncertainty to a record or site review.

Where the paperwork lives now: DOB NOW: Safety

DOB's Local Law 152 Follow-up #8 (opens in a new tab) says the legacy online portal closed after July 24, submissions paused July 25 and 26, and LL152 certifications and related transactions moved to DOB NOW: Safety on July 27, 2026. Initial certifications, correction certifications, extension and property-verification requests, inspection notifications, unsafe-condition notifications, and civil-penalty challenges or waivers all move into DOB NOW.

Who does the work

A Local Law 152 plumber for Brooklyn, Queens, Manhattan & the Bronx

LL152 inspections are performed by the Licensed Master Plumber the owner hires — not by a DOB inspector. Owners bring Austin in to do the inspection itself, and to fix anything it finds.

  • Brooklyn
  • Queens
  • Manhattan
  • The Bronx

A Licensed Master Plumber on every inspection

Austin is LMP #1879 — Rispoli family plumbing since 1968. The license behind your certification is the same company that shows up at the building.

Inspection, report, filing, and repairs in one shop

Inspection-only shops hand you a finding and a to-do list. Austin carries it end to end: the inspection, the GPS1 report, the DOB NOW certification, and the corrective gas piping work itself if your building needs it.

NYC gas piping is what we do all day

Brooklyn-based, serving Brooklyn, Queens, Manhattan, and the Bronx. Gas piping, gas restorations after shutoffs, and DOB compliance work are the core of our book — not a sideline.

What drives the cost of an LL152 inspection

No two buildings price the same. Four things move the quote:

Building size and piping footprint
More floors, more meters, and more risers mean more exposed piping to inspect and survey.
Access
Locked mechanical rooms, blocked pipe chases, and tenant coordination add time. An inspection that cannot reach every required area must be repeated — which is why we help you arrange access first.
What the inspection finds
Corrosion, illegal connections, or non-code-compliant conditions turn into separately scoped corrective work with its own permit and testing path. A clean building pays for an inspection, not a project.
Filing scope
Whether you want the inspection alone or the inspection with the DOB NOW certification supported end to end.

FAQ

Local Law 152 questions, answered

Direct answers on coverage, due dates, failed inspections, cost, gas shutoffs, filings, and extensions.

What is Local Law 152 and does it apply to my building?

Local Law 152 requires periodic gas-piping inspections for covered NYC buildings on a community-district cycle. DOB excludes one- and two-family homes and other buildings classified in Occupancy Group R-3, and publishes additional building classifications that do not need to comply. Confirm the property classification, gas-piping status, community district, and current DOB record before deciding that a building is covered or exempt.

How do I find my building’s Local Law 152 due date?

LL152 filing windows are assigned by community district, not by borough or address alone, so the first step is identifying the district recorded for the property. Enter the building address in the lookup on this page to see the recorded community district, its sub-cycle, and the assigned cycle year, or use the community-district table on this page and NYC Planning’s community profile lookup. The current DOB record for the property controls what is actually outstanding.

What happens if my building fails a Local Law 152 gas inspection?

Unsafe or hazardous conditions follow an immediate notification and correction path involving the owner, DOB, and the serving utility. The initial certification is still due within 60 days of inspection. When conditions requiring correction are reported, DOB describes a correction certification within 120 days, or within 180 days when the initial certification states that additional time is needed. Permits, testing, reinspection, and utility restoration depend on the condition and are not automatic for every finding.

How much does a Local Law 152 inspection cost?

It depends on the building, so treat any flat number you see online with caution. The main cost drivers are building size and the amount of exposed gas piping, the number of meters and risers, how much of the piping runs through spaces that need access arranged, and whether the inspection is bundled with the certification filing. If the inspection finds conditions that need correction, that work is scoped and priced separately from the inspection itself. Austin provides a clear scope and price for your building before any work begins.

Con Edison or National Grid shut off my gas. How quickly can service be restored?

There is no reliable universal restoration timeline. Timing depends on the unsafe condition, shutoff scope, permit and corrective work, required testing or inspections, document acceptance, and the serving utility. Start with the utility notice and an LMP assessment, then ask for a milestone plan covering filing, correction, testing, DOB acceptance where required, and utility authorization. For an active gas odor, leave the area and contact 911 or the serving utility emergency line.

Does every gas shutoff require a DOB filing?

Not always, but frequently yes. If the shutoff was triggered by a gas piping condition that requires physical correction — new piping, rerouted lines, new connections — a DOB permit must be filed by a Licensed Master Plumber before that work can begin. If the shutoff was due to an appliance issue rather than a piping issue, the path is different. We assess the specific cause of the shutoff and tell you exactly what filings are required. We don't create unnecessary permits, and we don't skip required ones.

What are the GPS1 report and the GPS2 form, and is GPS2 still required?

The GPS1 is the Gas Piping System Periodic Inspection Report — the Licensed Master Plumber’s findings, given to the owner within 30 days of the inspection. GPS2 was the form name for the Gas Piping System Periodic Inspection Certification under the legacy Local Law 152 filing process. DOB’s Local Law 152 Follow-up #8 says LL152 certifications and related transactions moved to DOB NOW: Safety on July 27, 2026, and that the paper GPS2 is no longer required for new Cycle 2, Sub-cycle C submissions after the cutover. A pre-cutover correction case that requested additional time follows DOB’s separate transition instructions.

Where do I file a Local Law 152 certification now?

Beginning July 27, 2026, DOB directs LL152 certifications and related transactions to DOB NOW: Safety, and the legacy online portal closed after July 24, 2026. Initial certifications, correction certifications, extension and property-verification requests, inspection notifications, unsafe-condition notifications, and civil-penalty challenges or waivers all move into DOB NOW. DOB NOW filings do not appear in BIS, so a complete record review may require both systems.

Can I get a Local Law 152 extension?

DOB’s process includes extension requests, which are filed in DOB NOW: Safety as of July 27, 2026. Separately, when the initial certification states that additional time is needed, DOB describes a 180-day correction-certification path instead of 120 days. Keep in mind that an extension provides additional time; it is not proof that an inspection or certification was completed. Whether an extension applies to your situation depends on DOB’s current rules and the property record — we can review both and tell you what is actually outstanding.

What is CSST gas piping and why does it come up in LL152 inspections?

CSST is corrugated stainless steel tubing used for some gas-piping installations. When exposed building gas piping includes CSST, the inspector evaluates the conditions required by the current LL152 rule. Piping and appliance connections inside tenant spaces remain outside the periodic-inspection scope, and the material alone does not establish a violation. If separate repair or permitted work is needed, Austin scopes that work from the actual condition rather than treating the material alone as an automatic violation.

Reference

No need to read this end to end — find the situation that matches your building, or use the lookup above to jump straight to it.

Reference

Local Law 152 reference: what a gas piping inspection lookup can tell you

The address tool above sorts a building into one of a handful of situations and gives it the matching next step. Each one is set out here in the tool's own words — the outcomes, the cycle schedule for all 59 community districts, the record distinctions, and the limits — so you can find yours without running the lookup at all.

Before anything else, if there is a gas odor or a suspected leak

An active gas odor, suspected leak, or unsafe condition is not a routine deadline-planning issue. Do not wait for an LL152 lookup or a reply from this website.

Leave the area and call 911 when there is immediate danger. Follow emergency instructions and do not operate switches, flames, or equipment in the affected area.

Every gas piping inspection outcome, and what to do next

If your building’s gas is shut off or red-tagged

A utility shutoff or red tag is separate from LL152 filing status. Resolve the safety and restoration requirements before treating this as routine cycle planning.

  • Follow the utility or agency notice. Confirm the requirements shown on the shutoff, red tag, or unsafe-condition record with the issuing utility or agency.
  • Arrange licensed restoration review. Use a Licensed Master Plumber for the field and Gas Authorization process; that work does not itself prove LL152 certification.
  • Verify LL152 separately. Check DOB NOW: Safety and BIS as applicable because restoration and LL152 are different records.

Austin handles the licensed side of that work — see gas piping and gas restoration work.

If you already had this cycle’s inspection

You report that an inspection occurred, but have not identified accepted certification confirmation. The inspection report alone does not prove submission or acceptance.

  • Check the current DOB NOW: Safety record. Verify the exact certification, Notice of Deficiency, extension, violation, and displayed status as applicable.
  • Review any remaining inspection or filing step. Bring the report and official records for property-specific compliance review.

If you also have the accepted certification confirmation, the answer changes only slightly:

You report both an inspection and accepted certification confirmation. The tool cannot verify acceptance; confirm the exact DOB NOW: Safety record, retain the records, and plan for the next displayed window.

Not sure which window the building was in? Check the address for the recorded community district and assigned cycle year.

If your building has no gas piping

Do not infer “no piping” from a locked meter, inactive account, or lack of appliances. Confirming there truly is no gas piping uses its own current official certification process.

  • Confirm that the building truly contains no gas piping. Under current DOB instructions, a no-piping certification may come from an LMP, Registered Design Professional, or utility company. Do not rely on your own impression.
  • Verify the current no-piping certification process. Review the current DOB guidance and DOB NOW: Safety record; do not substitute inactive-service documents.

If the gas is inactive and no appliances are connected

Piping that remains in a building with no active gas supply and no connected appliances is not the same as a building with no gas piping.

  • Confirm piping, service, and appliance facts. Do not infer permanent discontinuance from an inactive account or locked meter; use site and utility confirmation.
  • Follow current inactive-service instructions. Verify the separate utility-statement and owner-certification process in current DOB guidance.

If the record shows a missed cycle

The displayed cycle window has passed and you have not identified an accepted certification confirmation. This does not by itself declare a violation.

Tell the tool which record you are actually holding and it answers each one separately:

A Notice of Deficiency
You selected a Notice of Deficiency. It is not interchangeable with a violation, and the tool cannot confirm its current official status.
A Local Law 152 violation
You selected a violation record. Verify the exact official record and displayed status before deciding what inspection, correction, or filing step remains.
An extension
You selected an extension. An extension provides additional time; it is not proof of inspection, accepted certification, or completed compliance.
  • Check DOB NOW: Safety and BIS. Confirm the exact displayed filing, Notice of Deficiency, violation, extension, and status. DOB NOW filings do not appear in BIS.
  • Arrange a compliance record review. Bring the prior report and all official notices so the next responsible inspection, correction, or filing step can be identified.

For the wider DOB record path, see our DOB violation removal service.

If your building class appears exempt

The public building class appears on a commonly exempt-class screen, but the tool cannot make a legal exemption finding.

  • Check current DOB and DOF property records. Verify the classification, occupancy, and DOB NOW/BIS records; conflicting or stale public data requires manual review.
  • Request property-specific review when uncertain. Use the Certificate of Occupancy and actual property facts rather than the screen alone.

The screen runs on the public building class, which you can see for yourself when you look up the property.

If the records are unclear

Some of what we'd need isn't in the public records, or your answers left it open. That's normal — it just means someone has to look at the records or the building rather than guess. Don't assume the building is exempt, compliant, no-piping, or actively supplied until it's checked.

  • Review both current official record systems. Use DOB NOW: Safety and BIS as applicable, then compare the displayed records with the Certificate of Occupancy and property facts.
  • Confirm unknowns through record or site review. An LMP can help distinguish piping presence, inactive service, access, field conditions, and the right next step.

Start with what the public record does show — run the address — and take the unknowns from there.

When is my Local Law 152 gas piping inspection due?

Local Law 152 assignments are keyed to the community district number citywide, not to the borough — so two buildings in different boroughs that sit in districts with the same number share the same gas piping inspection year.

What the year actually means

Stated the way the lookup states it, for the next round of windows:

Sub-cycle A (Districts 1, 3, 10)
If this building is covered, the inspection itself needs to happen by December 31, 2028.
Sub-cycle B (Districts 2, 5, 7, 13, 18)
If this building is covered, the inspection itself needs to happen by December 31, 2029.
Sub-cycle C (Districts 4, 6, 8, 9, 16)
If this building is covered, the inspection itself needs to happen by December 31, 2030.
Sub-cycle D (Districts 11, 12, 14, 15, 17)
If this building is covered, the inspection itself needs to happen by December 31, 2031.

DOB's rule then gives the LMP up to 30 days to deliver the inspection report and the owner up to 60 days to complete certification — so certification can land after that date, depending on when in the window the inspection happens.

If your building is inside an open window right now

The displayed cycle is open and you report active gas and connected appliances. Schedule enough time for full access, findings, correction, and official record verification.

  • Schedule an LL152 compliance review. A Licensed Master Plumber can review the property facts, access plan, current cycle, and records before the inspection.
  • Verify the official filing record. An inspection report is not proof that the separate certification was submitted or accepted.

District assignments repeat every four years. For the schedule in more depth, see the LL152 deadlines by community district guide.

The records owners most often mistake for each other

Whichever outcome applies to a gas piping inspection file, the tool draws the same record distinctions:

Inspection report is not filing confirmation
The plumber’s inspection report and the separate DOB certification are different records. Receiving the report does not prove that a certification was submitted or accepted.
Notice of Deficiency is not a violation
A Notice of Deficiency and a DOB violation are different records and should not be treated as interchangeable.
Extension is not completed compliance
An extension provides additional time; it is not proof that an inspection or certification was completed.
No piping and inactive service are not the same thing
A no-gas-piping certification is different from the utility statement and owner certification used when piping remains but service is inactive and no appliances are connected.
Gas Authorization is separate
A Gas Authorization for service restoration is separate from LL152 inspection and certification records.

What an address lookup cannot confirm

The same limits apply to every outcome above, whichever one matches your building:

  • This result is preliminary. It does not confirm accepted filing status, legal exemption, physical gas-piping presence, active gas service, site conditions, or completed corrective work.
  • DOB NOW filings do not appear in BIS. A complete official-record review may require DOB NOW: Safety, BIS, and confirmation from the site, DOB, or the utility.

CSST Gas Piping and LL152 Compliance

Corrugated Stainless Steel Tubing (CSST) is a flexible gas-piping material used in some NYC buildings. Its presence alone does not establish an LL152 deficiency. The relevant question is whether exposed piping and its installation show a condition covered by the current rule or another applicable code path.

When exposed building gas piping includes CSST, the inspector evaluates the conditions required by the current LL152 rule. Piping and appliance connections inside tenant spaces remain outside this periodic inspection's scope. If separate repair or permitted work is needed, Austin scopes that work from the actual condition rather than treating the material alone as an automatic violation.

Schedule Your LL152 Inspection

We'll review the property record, schedule your inspection, and take it from there — the DOB notice, the inspection itself, the DOB NOW certification, and any corrective work your building needs. One call, start to finish.
