NYC 2022 Code: Chapter 33 Code Revisions – BC 3303.16 Worker Sheds, Contractor Sheds and Similar Structures
In our SAFETY Updates series we’ll be sharing important revisions to NYCDOB’s Chapter 33 Construction Code – Safeguards During Construction or Demolition
BC 3303.16 – Worker Sheds, Contractor Sheds and Similar Structures
The existing code did not require a permit for contractor shanties/offices, even though DOB inspectors often asked for permits for large contractor offices. The shanties/offices within 30 feet of an existing bldg., a new bldg., or another shanty/office had to be non-combustible construction with few exceptions (exceptions limited to 1 story and 120 square feet in area, more than 30 feet from another shanty/office, and constructed of fire-retardant wood protected from elements by sheet metal).
The revised code now requires the installation of smoke detectors and wet sprinklers or dry chemical extinguishers (commonly used today) and compliance with egress requirements of Chapter 10, as they relate to door width and travel distance. The construction of the shanty/office must meet the requirements of Class I, II (non-combustible) or III fire-resistant construction (protected combustible), depending on the location of the shanty/office (inside structure, inside fire district, within 30 feet of another shanty/office).
A permit is needed for the construction of the shanty/office, except if the shanty/office does not exceed 1 story and 120 square feet and is located more than 30 feet from another shanty/office. However, permits are needed for all utility hookups (electric, plumbing, etc.) without exception
