Sarah's Expert Insight
Senior Consultant at empcontracting.ca Inc.
"The NBC 2025 updates to barrier-free entrances represent a significant shift toward universal design in London, Ontario's construction landscape. At empcontracting.ca Inc., we emphasize that getting these technical clearances and threshold heights right during the framing stage is essential to avoid costly structural modifications during final inspections."
The National Building Code (NBC) 2025 has introduced refined standards for barrier-free design, ensuring that all public and residential buildings provide equitable access. For empcontracting.ca Inc. your construction contractor in London, Ontario, staying ahead of these accessibility mandates is a core priority for every project we undertake.
Core Requirements for Barrier-Free Entrances
Under the NBC 2025, every building must have at least one entrance that is barrier-free. In multi-tenant buildings or large-scale commercial developments, the code often requires more than 50% of all public entrances to be accessible. This ensures that persons with disabilities do not have to travel excessive distances to find an entry point.
Minimum Door Clearances and Maneuvering Space
Every barrier-free entrance door must provide a clear opening width of at least 850 mm when the door is open 90 degrees. Furthermore, the floor surface on both sides of the door must be level, providing a clear maneuvering area that allows wheelchair users to operate the door hardware and clear the swing path safely.
Threshold Heights and Transitions
The NBC 2025 specifies that thresholds at barrier-free entrances must not exceed 13 mm in height. Any threshold over 6 mm must be beveled to a slope of not more than 1:2 to prevent tripping hazards and ensure smooth passage for mobility devices. This technical detail is vital for maintaining the integrity of the building's envelope while ensuring accessibility.
Power Door Operators and Controls
Automated power door operators are no longer just an optional convenience; they are a code requirement for many occupancy types under NBC 2025. Controls must be located on the latch side of the door, positioned between 900 mm and 1100 mm above the finished floor, and placed so they are reachable before a person enters the door swing path.
