Every inspector has heard them. You walk up to a panel, and there it is: a wall of boxes, a fridge, a workbench, maybe somebody’s kayak. And the person on the other side looks at you with total sincerity and says one of these three things.
Excuse #1: “It’s just temporary.”
Temporary storage is still storage. The working space in front of electrical equipment has to be kept clear and unobstructed, and the 2024 IRC is blunt about it: the working space “shall not be designated for storage” (E3405.1). If it’s there today, it fails today.
Excuse #2: “You can still get to it. Just slide that out of the way.”
If you have to move anything to reach the panel, the space is not clear. A panelboard needs at least 36 inches of working depth, at least 30 inches of width (or the width of the equipment, whichever is greater), and clear height from the floor to 6.5 feet or the equipment height, whichever is greater (E3405.2). The panel door also has to open a full 90 degrees.
That space is sized for a reason: the person working at that panel needs room to stand, work, and get away fast.
Excuse #3: “It’s always been like that.”
Where the panel lives matters too. Panelboards and service equipment can’t go in bathrooms, toilet rooms, clothes closets, or over stairway steps, and indoor working spaces need lighting that isn’t controlled by automatic means only (E3405.1). Equipment, piping, and ducts foreign to the electrical installation can’t occupy the zone either. “Always been like that” just means it’s been wrong the whole time.
Why It Matters
The panel is the one place in the house where everything can be shut off in an emergency. When something goes wrong at 2 AM, nobody gets to schedule the failure, and nobody gets to move boxes first. That working space isn’t about inspector convenience. It’s the clearance a person needs when seconds count.
Keep it simple: 36 inches deep, 30 inches wide (or equipment width), 6.5 feet high. No storage. Door opens 90 degrees. Nothing foreign in the zone.
Studying for the ICC B1 or E1? Working space questions are exam gold. Know E3405.1 and E3405.2 cold, door-swing rule included. And if your jurisdiction needs help getting clearances enforced consistently, that’s what we do.
