I can't see a problem with a bookcase against a wall. 2007 NFPA 13 shows a detail of a soffit against a wall but that isn't the same as a shelf. Imagine the bookcase being no different than a framed out column.

Are they Obstructions? Forum members, I've drilled the 18" clearance issue into a building owners head and know he's got me scratching my head with a situation at his facility. He has a bookcase against a wall that is 12" deep with a clear space of about 6" above between the ceiling and the top of the bookcase. The sprinkler is 6" out in front of the bookcase. He's asking me why the bookcase is not an obstruction. It's Friday after a long week and I'm not sure why the book case is not an obstruction. What if the geometry was different? Let's say a cabinet that 24" deep and had 17" clearance between top of cabinet and ceiling? If you could point me to the right code sections, I would appreciate it. I have looked at supplement 7 in the residential handbook but this is an office building with standard spray sprinklers.
