OBC 2024 Lighting Requirements for Garages and Service Areas | empcontracting.ca Inc.

Understanding the 2024 Ontario Building Code (OBC) is essential for any renovation or new construction project. Sections 9.34.2.5 through 9.34.2.7 outline the specific requirements for lighting in storage rooms, garages, and public service areas to ensure safety and visibility. As empcontracting.ca Inc., your construction contractor in London, Ontario, we ensure every project adheres to these stringent electrical standards.

9.34.2.5. Lighting in Storage Rooms

The code mandates that every storage room must be equipped with a lighting outlet and a permanent fixture. This ensures that utility spaces are safe to navigate and functional for the homeowner.

9.34.2.6. Requirements for Garages and Carports

Garages and carports have specific regulations regarding how lighting is installed and controlled:

Switch and Fixture Locations

• General Requirement: A lighting outlet with a fixture is required for all attached, built-in, or detached garages and carports.
• Wall Switch Control: Standard installations must be controlled by a wall switch located near the doorway for easy access.
• Exceptions: If the fixture is ceiling-mounted in an area where a car is not normally parked, or if it is wall-mounted, a fixture with a built-in switch is permitted.
• Carport Lighting: If the entrance to the dwelling unit provides sufficient light to the carport, additional dedicated lighting may not be required under Sentence (4).

9.34.2.7. Lighting in Public and Service Areas

For buildings containing public or service areas, including recreational camps or worker housing, the OBC requires lighting outlets controlled by a wall switch or panel. These areas must meet specific illumination levels measured in lux (lx) or lighting power density (W/m²).

Table 9.34.2.7: Minimum Illumination Standards

To remain compliant, the following minimum levels must be met for incandescent lighting (or equivalents for LED/other types):

• Service Rooms and Laundry Areas: 200 lx (20 W/m²)
• Public Water Closet Rooms: 100 lx (10 W/m²)
• Garages and Storage Rooms: 50 lx (5 W/m²)
• Kitchens (Recreational Camps): 500 lx (50 W/m²)
• Service Hallways and Stairways: 50 lx (5 W/m²)

Whether you are upgrading a commercial space in Oakville or building a custom cottage in Muskoka, complying with these lux levels is vital for building permit approval and occupant safety.
