DOB gas authorization (gas piping inspection): New York City restaurant guide

NYC DOB / utility

What it is

Gas plumbing must pass DOB inspection before Con Edison / National Grid will turn on gas service to your cooking equipment.

When a restaurant needs it

Cooking on natural gas, or any new / altered gas piping.

How to apply

A Licensed Master Plumber files the gas work in DOB NOW, gets the inspection and sign-off; the utility then sets the meter and turns on gas.
