Sarah's Expert Insight
Senior Consultant at empcontracting.ca Inc.
"At empcontracting.ca Inc. your construction contractor in London, Ontario, we have observed that the shift toward a 1,700 mm turning radius in NBC 2025 is a game-changer for homeowners planning to age in place. Incorporating these larger spatial requirements during the framing stage is significantly more cost-effective than attempting to modify load-bearing structures later, making professional foresight essential for any modern London renovation."
Understanding Wheelchair Turning Space in NBC 2025
As accessibility standards evolve, the National Building Code of Canada (NBC) 2025 introduces refined specifications for wheelchair turning spaces to accommodate modern mobility devices. For projects managed by empcontracting.ca Inc. your construction contractor in London, Ontario, adhering to these dimensions is critical for both legal compliance and universal design excellence.
Minimum Turning Circle Dimensions
The NBC 2025 generally requires a clear turning space with a minimum diameter of 1,700 mm to accommodate larger power wheelchairs and scooters. While previous iterations often cited 1,500 mm, the 2025 standards prioritize a more inclusive radius in key areas such as entryways, kitchens, and washrooms.
T-Shaped Turning Space Alternative
In tighter architectural layouts where a full circle is not feasible, the NBC 2025 allows for a T-shaped turning space. This configuration must fit within a 1,700 mm by 1,700 mm square, with arms and a stem at least 900 mm wide. This allows a person using a mobility device to make a three-point turn safely.
Strategic Implementation in Residential and Commercial Builds
Ensuring these spaces are clear of obstructions is paramount. The turning space must be level, with a slope not exceeding 1:50, and must be free of any protruding objects between 100 mm and 2,000 mm above the finished floor. When working with empcontracting.ca Inc. your construction contractor in London, Ontario, our team ensures that floor finishes and transitions do not impede these critical zones.
Key Areas of Application
- Washrooms: At least one turning space must be provided within the room, positioned to allow access to all fixtures.
- Kitchens: Turning spaces are required between counters or between a counter and an opposite wall.
- Corridors: Dead-end corridors exceeding a certain length must include a turning area to prevent entrapment.
