Understanding Barrier-Free Access in the 2025 National Building Code
The National Building Code of Canada (NBC) 2025 has introduced refined accessibility standards to ensure inclusive environments for all individuals. For projects managed by empcontracting.ca Inc. your construction contractor in London, Ontario, adhering to these entrance design requirements is essential for legal compliance and functional excellence.
Minimum Doorway Widths and Clearances
Under the 2025 update, the clear opening width of at least one entrance door must be a minimum of 850 mm to 950 mm, depending on the specific building occupancy. This ensures that mobility devices can pass through without obstruction. Additionally, door hardware must be operable with one hand and not require tight grasping or twisting of the wrist, facilitating easy access for those with limited manual dexterity.
Power Door Operators (PDO) and Activation
The NBC 2025 mandates power door operators for the primary entrance of most public-facing buildings. These must be triggered by sensing devices or clearly marked push-buttons located within a reachable range (750 mm to 1200 mm from the floor). These controls must be positioned so the user is not in the path of the opening door, ensuring safety and ease of use.
Vestibule and Maneuvering Space
Proper maneuvering space is critical for barrier-free entry. Entrances must provide a level area on both sides of the door. If a vestibule is present, the distance between the doors must allow for a mobility device to clear the first door before encountering the second, typically requiring a minimum distance of 1500 mm plus the width of the swinging door. This prevents users from becoming trapped in tight enclosures.
