Occupied Rooftops: The Sky's the Limit

This presentation is on the International Building Code’s (IBC) roof top occupancy provisions, covering the International Code Council’s initial adoption through the current 2021 IBC updates, including addressing challenges of fires on a roof. These code provisions and recent changes guide building owners and operators and design architects on the use and occupancy of the roof of a building so as to be permitted to be classified as a normally occupied space, as opposed to a story, for use by the public to enjoy. Occupying a roof adds a relatively low cost sustainable area to the building while also giving the Owner/Operator/Architect the flexibility of providing a new use not currently offered, especially for adaptive re-use projects. In addition to the major building and fire code ramifications, the presentation will also address potential structural loading implications and roofing (waterproofing) considerations.


Learning Objectives:

  • Understand the building code provisions for means of egress that will be required for exiting from an occupied rooftop.
  • Recognize the ramifications of a rooftop outdoor assembly area to the design and application of the fire and life safety systems.
  • Apply the provisions of the International Existing Building Code when introducing rooftop assembly spaces to an existing building.
  • Consider the implications of a rooftop outdoor assembly area from a structural standpoint regarding the additional loads and from an architectural standpoint regarding roofing and waterproofing.
