How can I frame around a service panel in the corner of the room and maintain clearance?
Looking at that photo you would need 30 inches measured from the left side of the panel to the right. Your cover door would need to be hinged on the left side of the panel (if allowed) my current area allows decorative covers but a label has to tell what is behind the panel and it can not be locked. With the cover door able to open 90 degrees I would not expect it to get flagged.
