Fire suppression required for I-4 Daycare (corridor requirement)

[Fast_Edd1e]

I am working on a change of use building that defers alot of the requirements back to the IBC. (Michigan building code)

When it comes to I-4 for daycare facilitys, the code states. Section 903.2.6 for Group I exception 2. Sprinkler not required in Group I-4 where each care area is provided with one exterior exit door. Which this facility will have.

However, when it comes to corridor fire rating. The chart on 1020.1 says its Not Permitted without sprinkler system.

Does this chart take into effect the use of the exception 2 for fire suppression requirements? Since the corridor is not a required means of egress with the exit doors? Or does the corridor push it to be required?

Thanks

Michigan mess that up?

Michigan uses the 2015 IBC, which did not permit Group I-4 in Table 1020.1 to be without a sprinkler. This was corrected in the 2018 IBC for that very reason: Section 903.2.6 and Table 1020.1 do not correlate.

I suggest requesting a code modification to use the 2018 correction and all subsequent code editions as the basis to allow corridors with a 1-hour fire-resistance rating.

Are you sure it is an I-4? Do you have more than 100 children under 2.5 years old?
