<div dir="ltr"><div>It is 2024 IRC R330.4(4) Locations but I believe it is not written to apply to the garage door, just utility closet, basement, storage space within the dwelling unit. The attached garage requirement (2) sends you to R302.6 which is drywall requirements, not to the door reqs in R302.5.1. So that is a bit confusing, maybe it is locally amended language. </div><div><br></div><div><br></div><div><br></div><div><img src="cid:ii_mbp7fxxv1" alt="Screenshot 2025-06-09 at 4.45.18 PM.png" width="559" height="217"><br></div>

I've installed ESS in my town before and the only issue we went back and forth on was the parking bollard / vehicle protection aspect. But this entry door requirement is not something I had seen before. <br>
<br>
Anybody know where I might find this requirement?</div>
