On March 12, 2014, a gas explosion ripped through two buildings in East Harlem. Eight people were killed, dozens were injured, and more than 100 families were displaced. A year later, another gas-related explosion devastated buildings in the East Village, killing two people and injuring many others. New York City Council
These tragedies forced New York City to take a much closer look at something hidden behind the walls, ceilings and basements of thousands of buildings: the city's aging gas piping systems.
The response wasn't just Local Law 152.
In 2016, the City Council passed a package of gas-safety legislation designed to strengthen the rules surrounding gas work and gas piping. The new laws addressed issues including qualifications for performing gas work, final inspections of gas piping, procedures when a gas leak is suspected, utility shutoffs, and periodic inspections of building gas piping systems.

One of those laws was Local Law 152 of 2016.
What Did Local Law 152 Change?
Before Local Law 152, most building gas piping wasn't subject to a citywide requirement for periodic inspection simply because it had been sitting there for years.
Local Law 152 changed that.
The law created a system requiring covered buildings to have their gas piping periodically inspected by a Licensed Master Plumber or a properly qualified individual working under the direct and continuing supervision of one. NYC Government
The inspection isn't just looking for a gas leak. The law calls for exposed gas piping to be examined for conditions such as excessive corrosion, deterioration, illegal connections and non-code-compliant installations, while specified areas are also checked for gas leakage with a combustible gas detector.

More Than Just Local Law 152
This is the part of the story that often gets lost.
Local Law 152 wasn't created by itself. It was one piece of a broader effort to change how New York City approaches gas safety — from who is qualified to perform gas work, to how that work is inspected, to what happens when unsafe conditions are discovered. NYC Government
Today, most building owners simply know it as "the Local Law 152 inspection."
But behind that inspection is a much bigger story.
It was born from tragedy, and its purpose is prevention.
