Frequently asked questions

What is the most common NYC building deadline?

December 31. Boiler inspections and elevator periodic and Category 1 tests all run on a January 1 to December 31 cycle, and gas piping, parking and retaining wall deadlines also fall on December 31 of their assigned year.

How do I know which sub-cycle my building is in?

It depends on the requirement. Facades use the last digit of the tax block number. Gas piping uses the Community District. Parking structures use the borough and Community District. Retaining walls use the borough.
