I' m new, but going to jump right in. Our department requested an interpretation from the ICC regarding garage ventilation in R-2 occupancies. I would like to hear responses from others regarding the proposed question(s). I will refrain from indicating my opinion at this time. The interpretation request is as follows:
Code Reference: International Building Code International Mechanical Code
Code Edition: 2006 IBC and 2006 IMC
Code Section: IBC Sec. 1203.4 and IMC Sec. 401.2
Questions: We have a situation where we have a common, multi-stall garage attached to a multi-family residential condominium. The garage is a private garage that is used for the storage of private or pleasure-type motor vehicles and is considered a U occupancy (IBC Section 406.1.2). The interior of the garage is open with no separation walls between stalls. Each stall is provided with a separate overhead door opening. IBC Section 1203.4 and IMC Section 401.2 appear to indicate that ventilation can be provided by natural means. The overhead door for each stall satisfies the required minimum openable area to the outdoors (IBC Sec. 1203.4.1 and IMC Sec. 402.2). Does this garage need to be provided with mechanical ventilation? Does IBC Section 1203.4.2 and IMC Section 401.6 require a mechanical exhaust system because of the exhaust fumes from the motor vehicles?
The only "incorrect" statement above is relating to the garage doors. There are actually two garage doors for four stalls, not "Each stall is provided with a separate overhead door opening", as written. What do you guys think?
