Article 17 - MIXED CONSTRUCTION

Section 27-286

Section 27-286

  §  27-286  Classification.  When  two  or more classes of construction
occur within the same building, the entire building shall be subject  to
the  most  restrictive occupancy and size limitations for the classes of
construction involved. However, if the occupancies within the  different
classes  of  construction  are completely separated by construction that
meets the fire-resistance rating requirements for fire divisions  listed
in  table  5-2 then each occupancy so separated may, for the purposes of
this code, be considered as a separate building ("building section").

Section 27-287

Section 27-287

  §   27-287  Restrictions.  In  buildings  of  mixed  construction,  no
structural element shall be supported by  construction  having  a  lower
fire-resistance   rating  than  that  required  for  the  element  being
supported.
