Yes where NFPA 13 omits sprinklers the building is still sprinklered in accordance with NFPA 13 and is typically considered fully sprinklered. If Small Bathrooms Omit Sprinklers, Is the Building Still Fully Sprinklered? These sections are also reflected in the companion International Fire Codes.

The International Building Code also introduced provisions for omitting sprinklers in restrooms, beginning with the 2015 International Building Code. Starting with the 1997 edition of NFPA 101, language was introduced into the code to override the requirements in NFPA 13 and NFPA 13R. NFPA 101 only overrides NFPA 13 for specific occupancies, which are outlined below. Omitting sprinklers can offer a huge cost savings to these type projects. In studies of apartment fires where sprinklers were present, for instance, bathrooms were the area of fire origin in only 1% of total fires and resulted in no civilian deaths, civilian injuries or property loss (NFPA 101 Annex Material in A.30.3.5.4 & A.31.3.5.4).įrom a risk perspective, small bathrooms present a relatively low risk for fire origin and growth as compared to other areas of a building.Īlso, bathrooms in buildings with dwelling units also can comprise a major potential additional cost when they are repeated within each unit. These easily washable surfaces tend to also be less combustible than other building materials. Typically, since bathrooms require regular cleaning and are subject to variable humidity, surfaces can often be ceramic or non-porous.

Why Allow the Omission of Sprinklers in Small Bathrooms? Stay tuned for the big product launch coming in the next few weeks. This is week 2 of my 3 part series in creating resources for sprinkler designers, engineers, inspector's, and contractors. Note that this article covers requirements but also some helpful explanatory material pulled in from non-enforceable parts of codes and standards (such as the annex material). The path to determine whether an exemption applies is actually fairly complex which I'll explore today. I don't mind the question at all, because it has a relatively straightforward answer - they're either allowed to be omitted or not. 'Are sprinklers required in the bathrooms?' I get this question all the time from architects - especially when working around apartment, hotel, senior and assisted living facilities.
