NYC Local Law 157 is a regulation that requires natural gas detectors to be installed in residential and commercial buildings. The primary objective of the law is to enhance safety by detecting natural gas leaks early, thereby preventing potential explosions, fires, or other hazards associated with natural gas leaks.

Key Points of NYC Local Law 157:

  1. Applicability:
    • This law applies to both residential and commercial buildings in New York City. It mandates the installation of natural gas detectors in specific types of buildings, particularly those that use natural gas for heating, cooking, or other purposes.
  2. Installation Requirements:
    • The law specifies that natural gas detectors must be installed in certain locations within the buildings. These locations are typically near gas appliances and in areas where gas leaks are most likely to be detected early.
    • Detectors must be installed in accordance with the manufacturer's instructions and meet the standards set by the New York City Department of Buildings (DOB).
    • For Class A multiple dwellings, one or more natural gas alarms must be installed in each dwelling.  For Class B multiple dwellings, one or more natural gas alarms must be installed in each dwelling or a line operated zoned natural gas detecting system can be installed in all public corridors and public spaces.
