Local Law 126 · By December 31 each year
What this is

If the building has a parapet facing a street, sidewalk or other public way, a competent person (such as a mason, engineer or architect) must observe it every year and the owner keeps the report for DOB on request. Detached one- and two-family homes are exempt. Agency page

Gas piping inspection (2029 cycle) Likely applies
Local Law 152 · During 2029
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 5 is on the 2029 cycle; certification is filed with DOB after the inspection. Buildings with no gas piping file a certification instead. Agency page
