OBC 2024 Barrier-Free Standards: Guidelines for Exterior Walks and Doorways in London, Ontario
Sarah's Expert Insight
OBC Compliance Specialist
"In regions like London and Muskoka, the requirement for slip-resistant surfaces under OBC 3.8.3.2 is particularly vital due to our heavy ice and snow loads; we often recommend specific broom-finished concrete or textured pavers to ensure year-round compliance. As empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure that the 850mm clear width for doorways is meticulously measured from the face of the door to the stop, avoiding common inspection failures that delay occupancy."
Adhering to the 2024 Ontario Building Code (OBC) is critical for ensuring accessibility and safety in modern developments.

3.8.3.2. Exterior Walks: Compliance for Barrier-Free Access
Exterior walkways are a fundamental component of a barrier-free path of travel. Under Section 3.8.3.2, these paths must be designed as a continuous plane without abrupt changes in level. Key specifications include:
Surface and Gradient Requirements
- Width: A minimum uninterrupted width of 1100 mm is required.
- Gradient: The slope must not exceed 1 in 20; anything steeper must be designed as a formal ramp.
- Surface Quality: Walks must be permanent, firm, and slip-resistant.
- Visual and Tactile Safety: Transitions to vehicular routes must be identified with tactile attention indicators conforming to Article 3.8.3.18.
Specifications for Curb Ramps
For elevation changes of 200 mm or less, curb ramps may be utilized. These must be at least 1500 mm wide with a running slope between 1:8 and 1:12 depending on the vertical rise, ensuring a smooth transition for mobility devices.
3.8.3.3. Doorway Clear Width and Accessibility
Doorway accessibility is vital for interior and exterior navigation. The 2024 OBC mandates specific clear widths to accommodate barrier-free travel:
General and Residential Requirements
- General Path of Travel: Every doorway must provide a clear width of at least 850 mm when the door is open.
- Residential Suites: For bedrooms and bathrooms within a suite, the clear width requirement varies between 760 mm and 810 mm, depending on the width of the serving corridor.
