This project has a canopy. It canopy is not attached to the building. The building is required to have a sprinkler system installed in accordance with IBC 903.3.1.1 (an NFPA 13 system) in order to increase the allowable building area.
The canopy is providing weather protection for transit passengers. It's Type II-B, non-combustible, and made of steel, concrete, and metal panels. The canopy is also very large, and on its own exceeds the allowable area for a non-sprinklered Group A-3 occupancy.
Do the provisions of NFPA 13-2016 Section 220.127.116.11 (copied below) allow for an omission of sprinklers from an exterior canopy as described here?
18.104.22.168* Sprinklers shall be permitted to be omitted where the exterior canopies, roofs, porte-cocheres, balconies, decks, and similar projections are constructed with materials that are noncombustible, limited-combustible, or fire retardant–treated wood as defined in NFPA 703, or where the projections are constructed utilizing a noncombustible frame, limited combustibles, or fire retardant–treated wood with an inherently flame-resistant fabric overlay as demonstrated by Test Method 2 in accordance with NFPA 701.
A.22.214.171.124 Vehicles that are temporarily parked are not considered storage. Areas located at drive-in bank windows or
porte-cocheres at hotels and motels normally do not require sprinklers where there is no occupancy above, where the area is entirely constructed of noncombustible or limited combustible materials or fire retardant–treated lumber, and
where the area is not the only means of egress. However, areas under exterior ceilings where the building is sprinklered
should be protected due to the occupancy above.
