As Craig indicated, omitting sprinklers when there is not an exception either in the applicable IBC code or the applicable referenced NFPA standard will disqualify you from being considered full sprinklered throughout the building which is needed to take certain ICC tradeoffs... like an extra story height.

For example, it would not require additional sprinklers in pantries in a 13R building or sprinklers above a ceiling in a non-combustible 13 building. I have had AHJs in the past try to start adding sprinklers where the standard allows them to be omitted because they don't understand. Taking the exception for alternate means of protection that Craig mentions below may be fine with the adopted fire code and local AHJ but it is not in compliance with the standard.

Where terms are not defined through the methods authorized by this section, such terms shall have ordinarily accepted meanings such as the context implies. Merriam Webster's Collegiate Dictionary, 11th Edition, shall be considered as providing ordinarily accepted meanings. Throughout means throughout. We've just been through this definition issue with a local architect. Omission of sprinklers in a Control room with Sapphire provided is acceptable as an alternative by the AHJ but the building loses all advantages or allowances that are given to a fully sprinklered building since taking out sprinklers and substituting a gaseous system no longer qualifies as being sprinklered throughout. Basically any part of the code that allows you to do something a little more risky or bigger, higher, wider or of greater quantity or whatever based on a fully sprinklered building or where sprinklers are installed throughout, now goes away and you can't do those things. The Commentary spells this out in great detail. 2018, IFC Commentary, 903.1.1.

But I don't' see where the IBC tells me what "throughout" means. I've assumed it meant sprinklers in all areas that the applicable NFPA standard (NFPA 13 in this case) requires them, but not in areas that the applicable NFPA standard allows them to be omitted. I've learned, since the IBC doesn't define the term, there are jurisdictions that define it differently - more specifically they don't recognize the omissions that NFPA 13 allows, only the exempt locations listed in IBC section 903.3.1.1.1. Is anyone aware of an IBC document that would shed some light on this? I've found a number of articles from consultants, associations, etc., but something directly from the IBC would carry a lot more weight.
