Gas piping inspection (2026 cycle) Likely applies

What this is

Buildings with gas piping (except one- and two-family homes) need a periodic gas piping inspection by a licensed master plumber every four years. Community district 9 is on the 2026 cycle; certification is filed with DOB after the inspection. Buildings with no gas piping file a certification instead. Agency page
