Using 2006 IBC. A local small restaurant (2 story, 3B const type, B Group, no sprinklers) wants to replace a tent over a flat roof with deck (deck built to IBC Chap 16 req's). They want to scrap the tent (approved by Fire Marshal) and install a wood framed "pergola" with tent type membrane at roof and leave the sides open. This building is just about on the property line at one side and about 7'-9' from line on the other side of this deck. The wood structure would have 6 X 6 support columns extending down the exterior to the ground. The rooftop deck has proper egress and guardrails and is over a rear 1 story section of the building. So, he basically wants to install a wood framed permanent tent. I looked at 1406 and was having a tough time fitting this structure into that code section. Help appreciated as always. Thanks.

This may be considered a projection since it is not part of the main building.
Does it fall under the definition of a Canopy?
CANOPY. An architectural projection that provides weather protection, identity or decoration and is supported by the building to which it is attached and at the outer end by not less than one stanchion. A canopy is comprised of a rigid structure over which a covering is attached.
If so then.....it may have to be noncombustionable!
704.2.2 Type III, IV or V construction. Projections from walls of Type III, IV or V construction shall be of any approved material.
704.2.3 Combustible projections. Combustible projections located where openings are not permitted or where protection of openings is required shall be of at least 1-hour fire-resistance-rated construction, Type IV construction, fire-retardant-treated wood or as required by Section 1406.3.

Generally I picture a projection as being supported by the building and not having vertical supports at its ends. Since this structure sounds like it has a rigid frame, perhaps it is more similar to a Membrane-Covered Frame Structure (IBC 3102.2). However, the membrane material described in 3102.6.1.1 is required to be 20 feet above the deck.
Incidentally, the characteristics of the canopy material in 3105.4 are similar to the membrane material in 3102.6.1.1 and canopy coverings described in D102.2.8.
Sounds like a candidate for a modification (104.10) or alternative method (104.11).
