Emergency Planning & Preparedness Guide

The Virginia Statewide Fire Prevention Code (SFPC) requires certain occupancy types (Use Group) to develop and maintain Fire Safety and Evacuation plans. All requirements set forth in the SFPC for requiring these plans are driven by the "Use Group" of structures as defined by the Virginia Uniform Statewide Building Code (USBC). The SFPC requires that an approved fire safety and evacuation plan be prepared and maintained for the following occupancies and buildings.

  2. Group E
  3. Group H
  4. Group I
  5. Group R-1
  6. Group R-4
  7. High-rise buildings
  8. Group M buildings having an occupant load of 500 or more persons or more than 100 persons above or below the lowest level of exit discharge
  9. Covered malls exceeding 50,00 square feet (4645 m2) in aggregate floor area
