Not where I really want to be
Q: Is it correct that noncombustible concealed spaces must be protected with sprinklers when they exceed a certain height or depth?
A: No. There is no limitation in NFPA 13 to the size or dimensions of the concealed space that would trigger the need for sprinklers, so long as the space is truly a concealed space with no combustibles exposed.

What other factors other than fire-sprinklers need to be considered?
