have a minimum 2-hour fire resistance rating for
the floor construction located over the
basement. e Not less than the fire-resistance
rating required by other sections of this
code. f Not less than the fire-resistance rating
based on fire separation distance (see Table

and parking garages, the required fire-resistance
ratings for the structural frame, floor and roof
construction, including supporting beams and
joists, shall be permitted to be reduced by
1-hour where the building is protected throughout
with an approved automatic sprinkler system in
