Understanding the updated National Building Code of Canada (NBC) 2025 is essential for any successful renovation or new build. As empcontracting.ca Inc. your construction contractor in London, Ontario, we specialize in implementing these technical standards to ensure your space is fully accessible and compliant.
Minimum Clear Width and Doorway Clearances
The NBC 2025 dictates that accessible doorways must maintain a minimum clear opening of at least 850 mm. This width is calculated when the door is opened at a 90-degree angle, measuring from the face of the door leaf to the door stop. This ensures that mobility devices, such as wheelchairs and walkers, can pass through without obstruction.
Required Maneuvering Space
Code compliance extends beyond the door itself to the floor area surrounding it. Specific clearances are required on both the pull and push sides of the door to allow for the turning radius of assistive devices. For example, a minimum clearance of 600 mm is typically required on the latch side of a door that swings toward the user.
Hardware and Operability Standards
In accordance with NBC 2025, door hardware must be operable with one hand and without requiring tight grasping, pinching, or twisting of the wrist. This generally necessitates the use of lever-type handles or D-pulls. Hardware must be mounted at a height between 900 mm and 1100 mm from the finished floor to remain reachable for all users.
Threshold and Swing Requirements
Thresholds are a common tripping hazard and a barrier for wheels; the NBC 2025 requires them to be beveled and generally no higher than 13 mm. Furthermore, the closing speed of doors equipped with closers must be adjusted to allow sufficient time for passage, typically requiring at least 3 seconds to move from an open position of 70 degrees to a point 75 mm from the latch.
