RequirementDueStatus
Annual parapet observation Check
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

Annual property registration Check
HPD registration · September 1 each year
What this is

Residential buildings with three or more units, and one- and two-family homes the owner doesn't occupy, register with HPD every year ($13 fee). An unregistered building can't start a nonpayment case in Housing Court and faces civil penalties. Agency page

Sep 1, 2027
in 309 days		Required only if the owner doesn't live there
Gas piping inspection (2027 cycle) Likely applies
Local Law 152 · During 2027
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 11 is on the 2027 cycle; certification is filed with DOB after the inspection. Buildings with no gas piping file a certification instead. Agency page
