Gas Line Repair and Installation in New York City, NY
If you smell gas in New York City, leave and call 911 or your gas utility from outside. Once a utility shuts off gas because of a leak, it is not turned back on until a Licensed Master Plumber has repaired and pressure-tested the piping and the work has passed inspection, which can take far longer than the repair itself.

What is different about gas line repair and installation in New York City?
That restoration process is what catches building owners and residents off guard. The utility locks the meter, the plumber files for a permit with the Department of Buildings, the repaired piping is tested and inspected, and only then does the utility relight. In a multi-unit building an old piping system may fail its pressure test in more than one place, turning one leak into a larger repair.
Local Law 152 adds a routine obligation: most buildings other than one- and two-family homes must have their gas piping inspected periodically by a Licensed Master Plumber or a qualified person working under one. If you live in a co-op, condo or rental, the building handles this, and a failed inspection can also lead to a shutoff.

Gas shutoffs
If the utility shuts off gas because of a leak, service is not restored until a Licensed Master Plumber repairs and pressure-tests the piping and the work passes inspection. Under Local Law 152, most buildings other than one- and two-family homes also need periodic gas piping inspections.
What to check and ask before work starts in New York City
- Ask the plumber how the permit, pressure test and inspection will be scheduled and what the building must provide
- Ask whether the leak is on the building's piping or inside your unit, since that decides who pays
- Ask management when the building's last periodic gas piping inspection was done
- Never accept an offer to restore gas without the utility and an inspection

Gas Line Repair and Installation questions from New York City
How long does it take to get gas turned back on in New York City?
It varies widely. The repair may take a day, but the permit, pressure test, inspection and the utility's relight all have to happen in order. In older multi-unit buildings where the piping fails the test, restoration can take weeks or longer.
Can any plumber work on gas piping in NYC?
No. Gas work must be performed by a Licensed Master Plumber or by someone working under their direct supervision, with a permit from the Department of Buildings. Ask for the license number and verify it.
