I got into this a while back with an AHJ. The commentary in 13 is as Jack stated. If the building is required by the Code to be sprinkled throughout then it must be. No omitting sprinklers from various areas because someone doesn't want them or feels they will be a problem. Often architects or electrical types will want sprinklers left out of control rooms, telephone or data rooms, electrical rooms, ornate lobbies, etc. There are some cases where the omission of sprinklers is permitted but in doing so other restrictions or requirements are placed on that space, (rated enclosure, no combustible storage, etc.) Those requirements are very specific and don't apply to just any old space.
If either the Building Code or NFPA standard permits sprinklers to be left out of certain rooms like bathrooms and closets then it is still considered sprinkled throughout in accordance with the building code requirements. That's the final ruling we got from the AHJ (which was in our favor) and met the intent of the building codes. Craig L.

I believe there is something in the IBC commentary about this. Is a building NOT protected "throughout" if the heads in allowable bathrooms and/or closets are omitted?
