(OP)
I am working on a 5 story building with larger air handler units on the roof that you can walk into, do these need sprinklers in them

RE: fire sprinklers in aire handlers units
From NFPA 13 2013 ed, below is a new section...
Chapter 8 8.1* Basic Requirements.
Installation Requirements
8.1.1* The requirements for spacing, location, and position of
sprinklers shall be based on the following principles:
(8)*Sprinklers shall not be required to be installed within electrical equipment, mechanical equipment, or air handling units not intended for occupancy.
A.8.1.1(8) Equipment having access for routine maintenance should not be considered as intended for occupancy.

RE: fire sprinklers in aire handlers units
The building I am working on falls under 1996 NFPA # 13 since phase one and phase 2 were permitted in 1996, OSHPD has kept both building under that code evan though only phase 1 was built then and phase 2 is being built now
My question is, do you know what code would govern not installing sprinklers in the air handler unit for NFPA #13 1996. On phase 1 the air handler units are sprinkled but the inspection reports indicate that is was an as-built item because they store their filters inside the large 1 piece units
But now OSHPD seems to be holding me to do the same, not because code requires it, but because it was done on phase 1 and if I want to not do it or submit a change, it is on me to prove that they are not required

Current standards are usually the outcome of industry experiences that become the best rules.
Spdaddler50 is on the right track.

Looks like the wording LCREP posted above may have been first in the 07
are they designing the sprinkler system to the 96 nfpa 13 or a newer version??? hopefully a newer version
from 96:::
Chapter 4 Installation Requirements
4-1" Basic Requirements.
4-1.1" The requirements for spacing, location, and position
of sprinklers are based, on the follow!ng.principles:
(a) Sprinklers installed throughout the premises,
(b) Sprinklers located so as not to exceed maximum protection
area per sprinkler,
(c) Sprinklers positioned and located so as to provide satisfactory
performance, with respect to activotion time and
distribution.
Exception No. 1: For locations permitting omission of sprinklers,
see 4-13.1, 4-13.2, and 4-13.8. ~.
Exception No. 2: When sprinklers are specifically tested and test
results demonstrate that deviations from clearance requirements to
structural members do not impair the ability of the sprinkler to control
or suppress a fire, their positioning and locating in accordance
with the test results shall be permitted.
Exception No. 3: Clearance between sprinklers and ceilings exceeding
the maximum specified in 4-6.4.1, 4-7,.4.1, 4-8.4.1, 4-9.4.1,
4-10.4.1, and 4-11.4.1 shall be permitted provided that tests or calculations
demonstrate comparable, sensitivity and performance of the
sprinklers to those installed in conformance with these sections.
