I need to determine if my building requires sprinklers in accordance with Section 903.
Section 903.2.9 states "an automatic sprinkler system shall be provided throughout all buildings containing a Group S-1 occupancy where one of the following conditions exists:
1) A Group S-1 fire area exceeds 12,000 square feet
2) . . .
3) . . .
4) . . . "
The areas and occupancies are 7,000 sf S-1 & 6,000 sf S-2.
If I treat this as nonseparated mixed occupancies, then the following applies.
508.3.1 Occupancy classification. Nonseparated occupancies shall be individually classified in accordance with :Next('./icod_ibc_2009_3_sec002.htm')'>Section 302.1. The requirements of this code shall apply to each portion of the building based on the occupancy classification of that space except that the most restrictive applicable provisions of :Next('./icod_ibc_2009_4_sec003.htm')'>Section 403 and :Next('./icod_ibc_2009_9_sec001.htm')'>Chapter 9 shall apply to the building or portion thereof in which the nonseparated occupancies are located.
If the building has no fire rated construction anywhere, how big is the S-1 fire area? Is it 13,000 sf because there is no internal fire rated assembly that keeps the S-1 fire area at 7,000 sf?
Suppose the areas and occupancies are 7,000 sf S-1 & 6,000 sf B, separated occupancies (no separation required by Table 508.4) and no fire rated construction anywhere. Is the S-1 fire area still 13,000 sf?
Thanks in advance.
