Mandatory Gas Piping Compliance
Local Law 152 Gas Piping Inspections in NYC
Local Law 152 requires covered NYC buildings to complete periodic gas-piping inspections on a community-district cycle. An LMP or DOB-registered journeyman who completed approved training under LMP supervision inspects the areas included by the rule, the LMP provides the inspection report, and the owner completes the required certification path. Beginning July 27, 2026, LL152 certifications and related transactions move to DOB NOW: Safety.
Austin Plumbing & Heating performs LL152 gas piping inspections, prepares all required documentation, and handles corrective gas piping work when deficiencies are identified. One call closes the loop.
What Local Law 152 Requires
Local Law 152 applies to covered properties on a recurring community-district schedule. DOB excludes one- and two-family homes and other buildings classified in Occupancy Group R-3, and publishes other building classifications that do not need to comply. Coverage should be checked against the current property record rather than inferred from borough, unit count, or active gas service alone.
The inspection cycle is staggered across community districts. DOB's current gas-piping inspection guidance controls the schedule, applicability, certification steps, and civil-penalty posture.
July 2026 DOB NOW Transition
DOB's Local Law 152 Follow-up #8 says the legacy online portal closes after July 24, no submissions can be made July 25 or 26, and LL152 certifications and related transactions move 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 move into DOB NOW. For new Cycle 2, Sub-cycle C submissions after the cutover, the paper GPS2 is no longer required. A pre-cutover correction case that requested additional time follows DOB's separate transition instructions.
What the Inspection Covers
A thorough LL152 inspection examines:
- Exposed gas piping from the point of entry up to the individual tenant spaces
- Public spaces, hallways, corridors, and accessible mechanical and boiler rooms included by the rule
- Evidence of excessive atmospheric corrosion, illegal connections, and non-code-compliant conditions
- A leak survey using the instrumentation required by the current rule
- Accessible areas required for a complete inspection; tenant spaces and appliances are outside this periodic-inspection scope
The inspection entity must notify DOB at least two days before the inspection. The LMP provides the Gas Piping System Periodic Inspection Report to the owner within 30 days, and the owner submits the required LMP-backed certification within 60 days. Beginning July 27, 2026, the certification is submitted in DOB NOW: Safety and the paper GPS2 is no longer required for new submissions.
What Happens When Deficiencies Are Found
If the inspection reveals unsafe or non-compliant conditions, the LMP documents the result. 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. The initial certification remains due within 60 days; correction certifications follow DOB's 120- or 180-day path.
Austin can inspect, identify the condition, perform corrective gas-piping work, and coordinate the required permit, test, reinspection, certification, or utility steps. The exact path comes from the finding and property record; an LL152 condition does not automatically require every one of those steps.
Penalties for Non-Compliance
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; do not infer a property-specific balance or resolution path from a general article.
How to Know When Your Building Is Due
LL152 inspection schedules are organized by community district on a 4-year rolling cycle. Your due date is determined by your building's address and community district assignment — check yours below.

Schedule per the NYC DOB periodic gas piping inspection cycle, current as of July 2026. Deadlines can change — DOB's published schedule controls. DOB excludes one- and two-family homes and other Occupancy Group R-3 buildings; verify the building's current classification and applicability before relying on this screening result.
If you're unsure whether the expected certification appears in the current DOB record, contact us with your building address. We can review the available record, identify the assigned inspection year, and map any visible correction item to the next professional or official-record check. For the full schedule background, see our LL152 deadlines by community district guide.
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.
FAQ
Frequently Asked Questions
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.
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.
Con Edison 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 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.
