Gas Testing - Local Law 152

Understanding Local Law 152 and Gas Testing

Gas can be safe to use in buildings, but it’s important to make sure the gas lines are in good working condition, as there are hazards when using an older or damaged system. To combat the potential hazards, New York City has implemented Local Law 152, which dictates when and how buildings need to have inspections of gas lines and components within their building. Now into effect, property owners should be aware of the law and what they need to do to stay in compliance.

What is Local Law 152?

Local Law 152 was initially introduced in 2016 and went into effect in January 2019. It was not fully implemented until 2019 and inspections could not begin until January 1, 2020. The law covers the safety of gas lines and was created as a way to ensure gas pipes and lines in all buildings are inspected periodically to ensure they remain safe to use. According to the law, there are specific requirements for who can do an inspection, when it needs to be done, and what needs to be done once the inspection is complete.

Who Does Local Law 152 Testing Apply To?

All building owners must comply with Local Law 152 unless they are in occupancy group R-3, which means there are two or fewer families living in the building and less than 20 occupants in total. The law impacts more than a quarter of a million buildings in NYC. Those who wish to find out if their building is except will need to check the occupancy group classification on the building’s Certificate of Occupancy. If a building does not have gas pipes, the building owner must have that certified by a registered architect or engineer and the certification must be filed with the Department of Buildings. If this certificate is not filed, the building owner could be subject to penalties under Local Law 152, just like a building owner who does not complete the inspection on time.

The Requirements Under Local Law 152

There are several requirements under Local Law 152 that apply to all building owners who are not exempt. The building must be inspected by a qualified gas piping system inspector and the inspection must be done at least once every four years. Once the inspection is done, if no hazards are noted, the inspection certificate must be filed with the Department of Buildings. There are 60 days given for this to occur without penalty, and the inspector should return the completed certificate to the building owner within 30 days, providing ample time to comply. Building owners are also required to have the inspection reports and certifications on file for 10 years and to make them available to the Department of Buildings if requested.

Penalties for Failure to Comply

While the requirements can be complicated, the penalties are simple to understand. If a building owner does not comply with Local Law 152, meaning they do not have an inspection done or do not file the certificate in time, they can receive a penalty of up to $10,000. This penalty can be challenged within 30 days after it is received. After that point, the penalty will need to be paid by the building owner.

Remediation for Failure Under Local Law 152

If the inspection finds any issues with the gas piping system in the building, the inspector must notify the building owner and the Department of Buildings, as well as the utility company providing gas. The building owner must then bring the system up to code again. Work permits are required for any work done to the gas system and the building owner has 120 days to comply with the corrections. Within that 120 days, they must also have new inspections done and file the new inspection report with the Department of Buildings. An extension is available one time if needed.

Building owners in New York City, unless they own an exempt building, must make sure they comply with Local Law 152. Penalties for non-compliance are high, and the law is intended to help ensure buildings are safe for occupancy and free from any gas-related hazards. If it’s time for a building inspection, contact a qualified gas piping system inspector today to learn more about the process.

Inspections must be performed by a Licensed Master Plumber (LMP) by the deadline (see below) and the results must be reported to the Building Owner by DOB form GPS1 within 30 days of the inspection.

The certification of Inspection report “Gas Piping System Periodic Inspection Certification” - DOB form GPS2 must be filed with the DOB by the owner within 60 days of the inspection .

What our clients are saying...

Excellent work! The Spartakus plumbing team did a phenomenal job. They replaced my aging water tank with a brand new one, just within 2 hours. Job was very clean and very reasonable price. I cannot express in words how pleased I was with their service. Highly recommend to not look anywhere else but Spartakus!

Fast and friendly and couldn't be happier!

Great customer service and prompt response time with same day repair! Fast and friendly and couldn't be happier!! Thank you so much for making it a smooth repair, will recommend to friends! They were prompt and professional, and most importantly they explained everything they were doing thoroughly and would go through each step and show you what they are doing so you have confidence that they aren't just overselling / over repairing something.  Very reasonable labor costs, friendly, knowledgeable and patient.  

As a restaurant owner, I have little time to be preoccupied with non-food related issues. When a toilet inside our restroom sprung a leak, it nearly flooded the entire dining room. At this point, there was only one company to turn to. Spartakus. They fixed the leak within an hour and my business was up and running the very next day. I couldn’t have done it without these guys. 5 stars!!!

Truly a top rated company.

This company deserves more than five stars. They didn't just replace my heater and air conditioner, they built me a new system for my house. Going above and beyond is a understatement. Their staff was the nicest that I've ever come across. Truly a top rated company. Thanks Spartakus. Great job.

“Luckily Spartakus had the answer.”

My home has always been very susceptible to power outages. Our location high-up on a hill amplifies winds and exaggerates the affects of storms that roll through. My wife and I were tired of losing power with every simple rain storm. Luckily, Spartakus Plumbing had the answer with their incredible selection of generators. We found the right one within minutes and had it installed the very next day. Now, it would take a hurricane to keep us in the dark!
