What is a sleeping room? Over the years, when discussing the code in the office or in formal seminars, I have emphasized that the definitions chapter is one of the most important sections in any code book. It provides guidance on how to apply the requirements of the code. But what happens when we encounter a term critical to a code section that is not defined? According to Chapter Two of the 2021 edition of the International Residential Code (IRC), we can apply the definition as stated in other codes published by the International Code Council. If this approach does not resolve our issue, we can use the standard dictionary definition for our undefined term. But what if the term is not in the dictionary?

This is precisely the case with the term “sleeping room.” “Sleeping room” is found in multiple sections of the IRC, including Sections 310, 314, and 315 of Chapter Three. These sections govern Emergency Escape and Rescue Openings, Smoke Alarms, and Carbon Monoxide Alarms— all critical life safety requirements.

Is a sleeping room the same as a bedroom? The term “bedroom” is defined in the International Property Maintenance Code (IPMC). If “sleeping room” were intended to be interchangeable with “bedroom,” why not use the term “bedroom” in the IRC? Some jurisdictions have amended the code to include a definition for “sleeping room” during the adoption process.

If you’re the Building Official in your jurisdiction, this might be a good time to use the powers granted to you in Section 104.1 of the IRC and provide a written interpretation of the term “sleeping room.” In my opinion, the definition for “bedroom” in the IPMC is a good place to start.

Hopefully, you find this information useful, or at least it gives you something to consider.
