Local Law 152 Inspections in Manhattan by a Licensed Master Plumber

Local Law 152 Inspection Services

New York City’s Local Law 152 requires gas piping systems in most buildings to be inspected by a Licensed Master Plumber once every four years. The inspection covers exposed gas piping throughout the building and must be filed with the Department of Buildings as a Gas Piping System Periodic Inspection Certification.

Our team performs Local Law 152 inspections for buildings across Manhattan, identifying any leaks, corrosion, or code issues in the exposed gas piping and filing the required certification with the Department of Buildings on your behalf.

Missing a Local Law 152 inspection deadline can result in DOB violations. We help property owners and managers stay ahead of their building’s inspection cycle so compliance never becomes a last-minute scramble.

How Often Does Local Law 152 Require Inspection?

Local Law 152 requires gas piping inspections once every four years, with the exact deadline determined by the building’s community district. Buildings classified as one- or two-family homes are generally exempt, but most other property types, including multifamily, mixed-use, and commercial buildings, are required to comply.

Local Law 152 Inspections in Manhattan: Local Considerations

A significant share of the Lower East Side’s housing stock, including co-ops like Hillman Housing and East River Housing, was built well before Local Law 152 existed, so much of the exposed gas piping our inspectors examine in this neighborhood has been in place for decades.

At the same time, newer buildings like Essex Crossing are just as subject to the same four-year inspection cycle, since Local Law 152 applies based on building type and community district rather than the age of the piping.

Because Manhattan buildings receive gas service through Con Edison’s distribution network, any deficiency found during a Local Law 152 inspection that affects the point of service connection is coordinated directly with Con Edison.
