The Importance of Natural Gas Detection
This guide is intended for those interested in natural gas detection in relation to Local Law 157 of the New York City Rules - including legislators, developers, building boards and managers, and information seekers on legislation status and relevant requirements. As the legislation progresses, information is regularly updated by ProSentry’s team of experts in smart monitoring systems for New York residential and commercial multi-family/unit real estate. The purpose of this guide is to:
Executive Summary: After two fatal gas explosions in 2014 and 2015, New York City Council passed Local Law 157 requiring all residences in NYC to have natural gas detection once there was a national standard. That national standard was published in 2022 and the DOB has since released its Final Rule, which went into effect on February 15, 2024. Requiring compliance on or before May 1, 2025, the law specifies that compliant gas detectors should be placed within one foot of the ceiling and at least 3 feet and no more than ten feet horizontally from all gas appliances. These gas detectors can be monitored and part of a system, or unmonitored. Buildings with monitored systems have the advantage of direct notification to building staff as soon as a gas leak is detected, allowing building staff to respond quickly to the site of the leak and potentially avoid whole building gas shut downs.
Local Law 157 - also known as Local Law 157 of 2016, LL157 and the gas detector law - is a citywide ordinance that requires the mandatory installation of carbon monoxide / smoke detectors and natural gas detectors in New York City residences once an industry standard had been established. It amended the NYC Housing Maintenance Code, which repealed sections 27-2045, 27-2046, 27-2046.1 and 27-2046.2 of the administrative code of the City of New York relating to smoke and carbon monoxide detecting devices. This standard was published in April 2022 as NFPA 715 by the National Fire Protection Association. Read Local Law 157 in its entirety.
The natural gas detector installation requirements that comply with Local Law 157 include:
Proposed New York State Senate Bill S3705 required that all residences in New York State have monitored natural gas detection and that those sensors would eventually report these leaks to the State. There have been 51 gas explosions in New York State over the last 13 years. As of this writing, New York State Senator Leroy Comrie is consulting with stakeholders about amending this bill, consistent with the new NFPA and Underwriter’s Laboratory standards, which state that notifications must go to a licensed and staffed central station, which alerts the building, 911, and utility company.
The passing of Local Law 157 followed three fatal incidents in New York and several other occurrences throughout the United States. As a result, the NYC Mayor’s office, City Council, Department of Buildings, Fire Department, and construction industry reviewed the regulations and procedures that governed gas piping permitting and installation. Consequently, they passed a series of Local Laws that affected gas piping permitting, installation, and inspections.
Risks of not having monitored gas in a dwelling include:
Committed to staying at the forefront for updates on Local Law 157 and NYC Rule Section 908-02, ProSentry is the most reliable New York leak detection company bringing industry-leading innovation to natural gas leak detection solutions for residential and commercial multi-family/unit real estate.
No. Carbon monoxide detectors do not detect natural gas leaks.
While local gas detectors sound an alarm to alert building owners in the event of a leak, monitored gas detectors are continuously remotely monitored to alert both building owners and proper authorities in the event of a leak. The advantages of monitored gas detectors over local gas detectors include:
Amplifying the benefits of monitored leak detectors, smart-sensor gas leak detectors additionally provide instant and continuous information to a staffed central station to help manage the gas leak event - including the exact leak location (specific building, unit, and appliance) and specifics (concentration of gas within the unit) with 30-second updates. Central station staff remains on the phone with 911 so first responders have up-to-the-moment information on the percentage risk of an explosion, safely guiding their response.
ProSentry is a trusted New York natural gas leak detection service provider for residential and commercial multi-family/unit real estate. ProSentry utilizes an ecosystem of wireless smart-sensors to provide real-time natural gas monitoring, information and alerts via its industry-leading platform. ProSentry’s smart sensors are placed near gas appliances in individual units and connect to wireless LoRaWAN (Long Range Wide Area Network) gateways placed every few floors in building stairwells to communicate detection data. Activated by scanning QR code and integrated with the ProSentry mobile app, each smart sensor is easily programmed with custom location and contact information. In the event of a leak, contacts are instantly notified via preferred communication methods, including text, email, app notification, and live operator call to the building’s front desk, resident manager, and relevant services in the case of emergency. ProSentry’s four call centers are UL-certified according to NFPA 715’s call center compliance regulations, fluent in English and Spanish and located across the country to ensure the strongest, most reliable service.
According to Constellation Energy, the signs of a natural gas leak include:
