Go To Full Code Chapter
When required by Sections 3303.12.2.1 through
3303.12.2.4, floors closed to the public in a new or existing building undergoing construction or demolition work shall be served by, at least, either:
- An elevator provided with Phase I and Phase II recall meeting the requirements of Chapter 30, which shall be kept in readiness at all times for Fire Department use; or
- A hoist meeting the requirements of Section 3318, which shall be available at all times for Fire Department use.
Exception:
An elevator or hoist is not required during the course of construction or demolition of
a building that does not require a permanent elevator.
3303.12.2.1 Initial Installation of an Elevator or Hoist During the Construction or Enlargement of a Building Whose Height Will Exceed 75 Feet
During the construction or enlargement of a building, once the topmost working deck exceeds 75 feet (22 860 mm) in height above the lowest level of the ground, all floors that are closed to the public and within 40 feet (12 192 mm) above the lowest level of the ground shall be served by an elevator or hoist meeting the requirements of this section. Where this measurement lands between floors, the measurement shall be rounded such that the elevator or hoist is brought up to serve the higher floor.
3303.12.2.2 Increasing the Height of the Elevator or Hoist During the Construction or Enlargement of a Building
During the construction or enlargement of a building, when the
topmost working deck exceeds 75 feet (22 860 mm) in height above the lowest level of the
ground and subsequent to complying with Section 3303.12.2.1, all floors that are closed to
the public and that are at least 4 stories or 48 feet (14 630 mm) below the topmost working deck, whichever is less, or for a building whose primary structural system consists of
structural steel, at least 4 stories or 64 feet (19 507 mm) below the topmost working deck,
whichever is less, shall be served by an elevator or hoist meeting the requirements of this
section. However, no more than two weeks after the topmost working deck has become a
walkable floor, a hoist or elevator meeting the requirements of this section shall be brought
up to serve all remaining floors in the building that are closed to the public.
3303.12.2.3 During Demolition
During the demolition of a building where one or more
floors are removed from the building, all floors in the building that are closed to the public
and that are more than 7 stories or 75 feet (22 860 mm) below the topmost working deck,
whichever is less, shall be served by an elevator or hoist meeting the requirements of this
section.
3303.12.2.4 Other Instances
During the alteration of a building that would require a
permanent elevator and where the scope of work does not constitute an enlargement or involve
the removal of one or more floors from the building, all floors in the building that are closed
to the public shall be served by an elevator or hoist meeting the requirements of this section.
