I'm currently working on a large, multi-family apartment building that includes several-hundred dwelling units. The building is four stories tall and each story has multiple exits. The building is divided up by several fire walls for allowable area purposes, so the exits are a combination of exit stairs and horizontal exits.
In a recent discussion, the AHJ indicated that he thought Emergency Escape and Rescue Openings complying with IBC 1030 were required for each bedroom in the building. On past projects, I have not seen this required in buildings where each story has two or more exits, so I decided to do a deep dive into the code requirements.
This project is under the 2015 IBC, but I have also included the 2018 language below, as this seems to further clarify the requirements.
In the 2015 language, the first sentence seems to indicate that for a Group R-2 occupancies, the emergency escape requirements apply when triggered by Table 1006.3.2(1) or 1006.3.2(2). As I described in a recent cheat sheet for single exits, these tables are allowances for having a single exit or access to a single exit from a story. In this case, every story has multiple exits, so the provisions of these tables do not apply. The 2018 IBC makes this even clearer.
The AHJ on this project is pointing to the second sentence from the 2015 IBC 1030.1, stating that all sleeping rooms below the fourth story require the openings. The second paragraph from the 2018 IBC has similar language.
In my opinion, the first sentence of IBC 1030.1 essentially functions as scoping language for the rest of the requirements. Since this project does not meet the conditions described in this scoping sentence, the rest of the requirements do not apply and the openings are not required.
Emergency Escape and Rescue Openings: What Do You Think?
In a Group R-2 building where each story has multiple exits, are emergency escape and rescue openings required?

One other item to keep in mind - if your project is a single-family home, you may actually be permitted under the International Residential Code (IRC), not the IBC. The IRC also has requirements for emergency escape and resuce openings, so be sure to check those out if applicable to your project.
On a related note, I was recently asked to provide input for an article on Redfin for basement remodelling projects (likely permitted under the IRC). Check out the link to the article here!
