Working under ORSC 2017, we have a detached ADU with a full-height basement that will be used by the main house for gardening type supplies. The plans checker is asking who the primary user of the space will be (or if it will be common space), and to address fire-rated construction per 302.3. My original intent was a layer of 5/8" Type X at the ceiling (per 302.6) like a normal garage, but it seems he's angling toward a dwelling unit separation even though the main house is 30' away. I'm not finding code info on common space separations. Thoughts?
