What Are the Rules for Wiring Inside a Closet?

Closets in Ontario homes are subject to specific wiring restrictions under the Ontario Electrical Safety Code (OESC). The rules exist because closets — particularly bedroom and hallway closets — are spaces where combustible materials (clothing, linens, boxes) are stored in close proximity to light fixtures and wiring. Understanding what the code permits and prohibits in a closet helps homeowners plan lighting upgrades, outlet additions, and storage system installations without creating code violations or fire hazards.

What Are the Rules for Wiring Inside a Closet?

The OESC applies the same rules to closet wiring as to any other interior space, but the fire hazard posed by combustible storage in proximity to light fixtures has historically driven specific guidance on light fixture placement and type in closets.

Light Fixtures in Closets

• Incandescent and halogen fixtures are not recommended in closets without adequate clearance between the fixture and any stored materials.
• LED recessed fixtures (pot lights) are the preferred choice for closet lighting — low heat output, IC-rated options available, no projection into storage space.
• Surface-mounted LED fixtures are acceptable when positioned so stored materials cannot contact the fixture face.
• Bare bulb fixtures (keyless lampholders) are a code concern – replace with an enclosed LED fixture.

Outlets in Closets

The OESC does not prohibit receptacle outlets inside closets. Bedroom closet outlets must have AFCI protection. Junction boxes must remain accessible.

Common Closet Wiring Violations

• Bare incandescent bulb socket with no clearance from hanging clothes
• Extension cord used permanently to power closet lighting
• Junction box buried inside finished soffit with no access panel
• Low-voltage LED driver hidden inside shelf cavity without listed enclosure
• New outlet added to bedroom closet without AFCI protection
