While reading up on the multi-polygons with buildings, I came across that type=building relation. It seemed to be more preferable when the building is complex, with a recommendation to just use a regular multi-polygon relation for simpler cases. There doesn't seem to be a consensus on which is best or preferred. I don't think this case merits construction using the type=building, so I will leave it if the OSM inspector is happy with multi-polygon. Thank you once again for your help and letting me know of the issue.
