What Is the Clearance Requirement in Front of an Electrical Panel?

Finishing a basement in a GTA home, adding storage in the utility room, or installing a laundry sink against the same wall as the electrical panel — all of these run into the same code question. How much space must stay clear in front of the panel? The Ontario Electrical Safety Code has explicit numbers, and inspectors enforce them strictly. This guide walks Ontario homeowners through the clearance requirement in front of an electrical panel, why it exists, and how to plan renovations around it.

Short answer: 1 metre clear in front, floor to top of panel plus 900 mm

Direct answer: Rule 2-308 of the Ontario Electrical Safety Code requires a clear working space in front of the panel measuring at least 1 metre deep, 750 mm wide (or the panel width, whichever is greater), and extending from the floor to at least 2 metres above the floor. The panel door must be able to open at least 90 degrees.

What the working space actually covers

• Depth (perpendicular to the panel face): 1 metre minimum. Nothing may permanently occupy this space — no shelves, no laundry appliances, no HVAC equipment, no boxes.
• Width (parallel to the panel face): 750 mm minimum, or the panel width if larger. This is the horizontal room the electrician needs to work.
• Headroom: 2 metres minimum above the floor, or 2 metres above any equipment being worked on, whichever is greater. Low basement ceilings sometimes fail this check.
• Panel door swing: the door must swing at least 90 degrees. Anything blocking the swing (a laundry basket, a stacked box, a nearby wall closer than the door radius) is a violation.
• Lighting: Section 26-808 requires illumination for the working space. A basement bulb over the panel is code-compliant; darkness is not.

Why the clearance rule exists

Direct answer: the working space rule exists to protect the electrician (or you) during any panel access — resetting a breaker, checking a smell, replacing a device, or opening the trim. Without adequate clearance, the operator cannot back away safely if an arc flash occurs, and cannot manoeuvre tools and PPE for hands-on work.

The Electrical Safety Authority lists inadequate working space as one of the recurring writeups on residential permit inspections in the GTA — often flagged during finished-basement, laundry-room, or utility-room permit work. Blocked panels do not just fail inspection; they make future service calls dangerous.

Real-world scenarios that fail the clearance rule

• Washer or dryer placed directly in front of the panel. Very common in older Toronto homes with panels in the laundry room. The dryer must move.
• Shelving unit installed on the panel wall. Even if the shelves are technically off the panel, they usually protrude into the 1-metre depth.
• Boiler or furnace in the same room with clearance to the panel less than 1 metre. HVAC equipment gets moved during panel service; if it is too close, service becomes impossible.
• Framed-in closet in front of the panel during basement finish. The finish gets rejected on inspection.
• Storage boxes stacked against the panel wall. Not technically permanent, but if they are there during the inspection, they are flagged.

Renovation planning: how to keep clearance

1. Mark the working space on the floor before any framing goes up. Painters tape a 1-metre-by-750-mm rectangle in front of the panel. Nothing enters that box.
2. Reserve the ceiling above the panel. Do not run ductwork, plumbing, or beams through the 2-metre headroom above the working space.
3. Plan appliance placement. Laundry appliances, water softeners, and utility sinks belong outside the working-space box.
4. If the existing panel is in the wrong place, consider moving it during the renovation. Our post on moving the panel covers the process.
5. Talk to your electrician early. Working space is one of the most common reasons a general contractor’s framing plan gets flagged mid-project.

What about the space behind the panel?

Direct answer: the wall behind the panel is usually a stud bay and is not affected by the clearance rule. What matters is what goes on the wall around the panel — conduit, cable trays, and other electrical equipment that shares the panel’s serviceable area are allowed. Non-electrical clutter, decorations, and finishes should not intrude into the working space.

Rule 2-320 covers the clearance requirements for the working space more precisely, including exceptions for panels installed in closets (generally not permitted for residential unless the closet is dedicated electrical).

Common exceptions and edge cases

Direct answer: temporary storage boxes are technically not permitted in the working space but are usually tolerated as long as the panel remains readily accessible. Permanent installations of any kind — shelving, appliances, drywall closets — are strictly enforced.

Panels installed at a slight angle (front face not parallel to the wall) still require the same clearance measured from the panel face, not from the wall behind it. That catches some homeowners off guard on older installations.

Expert tip from our ESA-licensed electricians

In our experience across GTA basement finishes, the single detail that saves customers from a costly framing redo is confirming the clearance with the electrician before drywall goes up. We routinely walk basement projects and mark the working-space box on the subfloor with masking tape. Homeowners who assumed “the panel is small, I only need a foot or two” are surprised at how much room a full 1-metre depth actually takes up in a finished basement. Half an hour of tape work before the drywallers arrive is the cheapest inspection insurance available. Our post on panel upgrade timing covers when a basement finish is the right moment to also upgrade.
