Understanding Local Law 157

Why now?

NYC passed Local Law 157 following two fatal gas explosions in in East Harlem in 2014 and the East Village in 2015. These tragedies resulted in numerous casualties and highlighted the city's vulnerability to gas leaks. In response, the city passed Local Law 157 that requires the installation of natural gas detectors in every apartment with natural gas hookups, in all residential buildings across the five borroughs. The goal is to ensure future natural gas leaks can be caught and addressed before they cause catastrophic damage. 

Key Requirements

The law stipulates that all dwellings, including in apartment buildings, houses, and hotels, with a natural gas appliance, must install natural gas detectors that meet specific standards set by the National Fire Protection Association (NFPA 715). These detectors should be installed within one foot of the ceiling and placed no less than three feet and no more than ten feet from each gas appliance. Compliance with these installation guidelines is mandatory, and failure to adhere to them can result in significant penalties.

Detectors must also comply with UL 1484 or UL 2075 standards, ensuring they are designed to detect combustible gasses and provide reliable alerts in case of a leak. These devices should be regularly maintained and replaced according to the manufacturer’s recommendations to ensure they remain functional over time.

Timeline for Compliance

Local Law 157 outlines a clear timeline for compliance. The final rule was published on February 15, 2024, with a compliance deadline of May 1, 2025. Property managers and owners must ensure that all required detectors are installed and operational by this date to avoid fines and other legal consequences.

Proactive planning is essential to meet this deadline. Property managers should start assessing their buildings’ needs, selecting appropriate detectors, and scheduling installations well in advance. Delaying these actions could result in a last-minute rush, increased costs, and potential non-compliance.

Importance of Natural Gas Detection

Enhancing Safety

Local Law 157's is primarily designed to protects  residents detecting  natural gas leaks before they cause harm. Natural gas is highly explosive, and even small leaks can pose serious risks. By installing compliant detectors, you can protect your tenants from potential hazards, including explosions and asphyxiation.

Natural gas is odorless, but utilities add a sulfur-like odor to help detect leaks. Despite this, many leaks go unnoticed until they reach dangerous levels. Detectors provide an additional layer of security, alerting residents and, with some detectors, building management to leaks before they become catastrophic.

Preventing Financial Loss

Beyond safety, complying with Local Law 157 can prevent significant financial losses. Gas leaks can lead to catastrophic loss of life and property damage. 

Insurance companies may also offer lower premiums to buildings equipped with compliant gas detection systems. By reducing the risk of gas-related incidents, you can negotiate better terms and potentially save on insurance costs. Additionally, maintaining compliance can protect you from lawsuits and liability claims in the event of an incident.

Steps to Achieve Compliance

Assess Your Building

The first step towards compliance is to determine whether your property falls under the categories specified by the Housing Maintenance Code, including private dwellings and Class A and B multiple dwellings. Understanding your building's classification will help you identify the specific requirements you need to meet.

Conduct a thorough inspection of your building’s gas appliances and identify areas where detectors are needed, noting how many detectors you will need, and where they can be installed to be compliant with guidelines. 

Choose the Right Detectors

Local Law 157 allows for various types of natural gas detectors, including hardwired, plug-in, and battery-powered models. As well as monitored, and unmonitored detectors. Each type has its installation requirements and benefits. 

Installation Guidelines

Proper installation is critical both to making sure the natural gas detectors work AND making sure they are compliant with the Local Law 97 guidelines. Hardwired detectors must be installed by licensed electricians, while plug-in and battery-powered detectors can be installed by building owners, maintenance personnel, or tenants. To comply with the law, ensure that detectors are placed at the specified distances from gas appliances.

Unmonitored detectors also need to be regularly tested to ensure they are functioning correctly. Schedule periodic maintenance checks and replace batteries or units as needed. Document all installations and maintenance activities to provide proof of compliance if required by authorities.

Concerns about Mass Gas Shut Offs

One of the key concerns with Local Law 157 is that it will result in potentially hundreds or thousands of buildings in NYC losing gas services for years following the installation of natural gas detectors. These highly sensitive devices are likely to result in an increase in reported gas leaks from tenants to Con Edison. In response, Con Edison may shut off gas service, leading to significant disruptions for residents. 

The process of restoring gas service is not immediate, as it requires comprehensive pressurization tests, which can extend the shut-off period for months or years. This could create severe inconveniences for tenants who rely on gas for essential services like heating, cooking, and hot water. Several companies have begun working on solutions to mitigate this issue using “smart” or “monitored” gas detectors. 

Choosing Your Natural Gas Detectors 

Unmonitored/“Dumb” Detectors vs. Monitored/“Smart” Detectors

The primary decision you will have to make when deciding between natural gas detectors is whether to use “dumb”/unmonitored detectors or “smart”/monitored detectors. 

Unmonitored detectors are available from many retailers like Amazon, and simply beep when they detect gas and typically have no monthly or annual fee associated with them.

Monitored gas detectors are continuously monitored over a wireless connection and both beep AND  send instant alerts via text message, email, and smart phone apps  when a gas leak is detected. This immediate notification allows building staff to respond quickly, potentially preventing the tenant from calling Con Edison resulting in a full building gas shutdown. Monitored systems also enhance safety by alerting management even if the tenants is not home, and ensuring that detectors are always functional by  providing real-time updates on their status. 

In addition to gas detection, monitored systems can integrate with other building safety features, such as fire alarms and emergency lighting. This holistic approach to building safety can provide  comprehensive protection for residents and the property.

Battery Powered or Hard Powered Gas Detectors

Both smart and dumb gas detectors come in battery powered and hard powered versions. Battery powered units have the advantage of being able to be screwed to the ceiling or a wall, preventing tenants from accidentally or intentionally unplugging the detector from an outlet, thereby disabling it.  

Hard powered detectors typically cost less upfront because they do not require batteries, but cost more over time due to their higher ongoing electric usage. 

Battery powered detectors may require batteries to be replaced every 3-10 years. Many smart gas detectors now support 10 years battery life however, which practically outlives the recommended life of any gas detector’s internal sensors. 

Natural Gas Detection As Part of Comprehensive Smart Building Controls 

Smart Building Control platforms can monitor and control numerous systems (like heating, cooling, water, etc) in buildings more intelligently. These platforms can substantially lower a building’s  utility costs and make the property safer. Some smart building control platforms use a single control and wireless network to monitor and control all aspects of the building. This makes rolling out smart natural gas detectors much lower cost when also rolling out the full smart building control platform. In many cases this can dramatically lower the cost of implementing both comprehensive natural gas detection, and smart controls for all systems across the building. 

The benefits of implementing a single smart building control platform that includes natural gas detection include:

• Substantially lower cost of implementation 
• All aspects of the building (and all buildings in your portfolio) managed with a single smart phone / web app 
• Gas detectors that also double as temperature and humidity detectors reducing the numbers of sensors needed in each unit and providing additional value to the building for free 
• Offsetting for the cost of natural gas detectors through lowered utility costs (smart building controls typically reduce heating and cooling costs by 20-25%)
• Availability of rebates from Con Edison and National Grid to pay for some or all of the cost of smart natural gas detectors if implemented along with smart heating control in a single platform 

If you are considering smart / monitoring natural gas detectors, you should evaluate whether it is advantageous to implement them as part of a smart building control platform.  

Educating Residents

Educating your residents about the importance of gas detection and safety measures is essential. Provide them with information on how to recognize the signs of a gas leak, such as the smell of rotten eggs or hissing sounds. Encourage them to report any suspicious signs immediately to building management or emergency services.

Hold regular safety meetings and distribute educational materials that explain how the gas detection system works and what residents should do in case of an alarm. By fostering a culture of safety, you can ensure that everyone is aware of potential risks and knows how to respond appropriately.

Regular Maintenance and Testing

Regular maintenance and testing of unmonitored / dumb gas detectors is crucial to ensure their functionality. Schedule periodic inspections and replace batteries or units as needed. Monitored systems can simplify this process by providing automated alerts when maintenance is required.

Document each inspection and any maintenance performed to ensure compliance and provide a record for future reference.

Penalties for Non-Compliance

Financial Penalties

Failure to comply with Local Law 157 can result in significant financial penalties. The New York City Department of Buildings (DOB) typically imposes fines for building code violations, and these can accumulate quickly with ongoing non-compliance. 

Legal Consequences

Beyond financial penalties, non-compliance can lead to severe legal consequences. If a gas-related incident occurs due to the lack of required detectors, property owners may face lawsuits from tenants or other affected parties. These legal battles can be both time-consuming and costly, resulting in increased legal fees and potential settlements. A history of non-compliance can also lead to higher insurance premiums and difficulties in obtaining future insurance coverage.

Safety Risks

The most severe consequence of non-compliance is the safety risk posed to tenants. Gas leaks can lead to explosions, fires, and fatalities, causing irreversible damage and loss. The responsibility for such incidents falls on the property manager or owner, further compounding the financial and legal repercussions. Additionally, a significant gas-related incident can result in the complete shutdown of a building, leading to loss of rental income and long-term tenant displacement.
