FAQ
Questions We Hear Every Day
Important answers about gas line work in NYC.
In New York City, gas line installation and repair must be performed by a licensed master plumber. Gas piping falls under the NYC Fuel Gas Code and the Administrative Code, which assign exclusive authority to master plumbers holding a DOB license. The work also requires a DOB gas piping permit and, for new service or upsized capacity, a Con Edison gas authorization. Unlicensed gas line work is illegal and can void building insurance coverage.
Local Law 152 requires periodic inspection of all gas piping within NYC buildings — including exposed piping in basements, boiler rooms, and public corridors — by a licensed master plumber. The inspection cycle is every four years, staggered by community district. The plumber visually inspects piping for corrosion, improper fittings, and unsupported runs, then files a report with the DOB. Buildings that fail or miss the deadline face DOB violations and potential gas service shutoff by Con Edison.
Natural gas in NYC is odorized with mercaptan — a rotten-egg or sulfur smell. If you detect that odor, leave the building without operating any electrical switches, open flames, or elevators, then call Con Edison's emergency line from outside. Do not attempt to locate or seal the gas line leak yourself. Additional signs include a hissing sound near piping, dead vegetation above buried lines, or a gas meter running with all appliances off.
A new commercial gas line installation in NYC starts with a load calculation to size the pipe for all appliances at full demand, then a DOB permit application filed by a licensed master plumber. The plumber installs black-iron or CSST piping from the meter to each appliance connection, pressure-tests the entire gas line at 1.5 times working pressure, and coordinates the final Con Edison inspection and meter activation. NYC also requires seismic shut-off valves in some commercial applications.
CSST — Corrugated Stainless Steel Tubing — is a flexible gas line material approved for use in NYC under the Fuel Gas Code, provided it is bonded per code to protect against lightning-induced arc damage. It's commonly used for equipment connections and through-wall drops where rigid black-iron piping is impractical. NYC DOB requires CSST installations to follow manufacturer bonding specifications and be filed under a master plumber's permit. Some co-op and condo boards prohibit CSST in shared chases; confirm house rules before specifying.
