Bill I looked back at the handbook and the standard to make sure I
understood the intent.
I'm not attempting to split the atom, however I note that the 2'
projection described in your post should include the phrase "greater
than 2 ft" as identified in §8.17.7.5. If the projection were exactly
2' wide, and combustibles were stored underneath, sprinklers are not
required to be installed underneath such an exterior projection.

The 2016 NFPA 13 handbook states that canopies less than 4' are not required to
have sprinklers, regardless of construction type, unless combustibles are
stored under them. Projections 2' or more require sprinklers, regardless of
construction type, if there are combustibles stored below it.

Subject: Re: NFPA #13 (2013) Exterior Projections 8.15.7
I think you are correct for your described situation: you have a noncombustible
overhang, under 4 ft, with no storage underneath, then no sprinklers is OK.
It sure seems to me like we don't have to install sprinklers under
*combustible* overhangs 4 ft or less as long as there is no storage underneath.
It doesn't say this explicitly (it just doesn't require sprinklers there, it
doesn't specifically omit them), so maybe there is a reason for that?

We have been discussing exterior projections in the office and with an
AHJ on when sprinklers are required.
Section 8.15.7.1 Unless the requirements of 8.15.7.2, 8.15.7.3. or
8.15.7.3 are met, sprinklers shall be installed under exterior
projections exceeding 4'-0" in width.
Section 8.15.7.5 Sprinklers shall be installed under exterior
projections greater than 2'-0" wide over areas where combustibles are stored.
Canopy is less than 4'-0" in width, No vehicle storage,
non-combustible construction, not a corridor, so all items are met for
8.15.7.1, no sprinklers required.
But 8.15.7.5 seems to requires them because the canopy is over 2'-0"
Normally we worked on the assumption less than 4'-0" and
non-combustible, no storage, no sprinklers required and the 2'-0" was
for combustible construction, over 2'-0" you required sprotection.
What are we missing
Thank You
