What are the Ontario Building Code requirements for slip-resistant tile in commercial spaces?

The Ontario Building Code (OBC) does specify slip-resistance requirements for tile in commercial applications, but this is actually outside the scope of what Ottawa Tiling typically addresses — our expertise is residential tile work for Ottawa homeowners rather than commercial spaces. That said, I can point you toward the right resources.

For commercial tile installations in Ontario, the OBC references ASTM D2047 (Standard Test Method for Static Coefficient of Friction of Polish-Coated Flooring Surfaces as Measured by the James Machine) and typically requires a minimum coefficient of friction (COF) of 0.5 for level walking surfaces and 0.6 or greater for ramps and stair treads in commercial buildings. The exact requirements depend on the specific use classification — retail, hospitality, healthcare, industrial — and the presence of moisture (wet areas like kitchens, bathrooms, and entryways have stricter requirements). The National Building Code of Canada and provincial amendments also play a role in how these standards are applied in Ontario.

If you are working on a commercial tile project in Ottawa, you should consult directly with the City of Ottawa Building Code Services (3-1-1 or ottawa.ca), your project's mechanical engineer or architect if one is involved, or a commercial tile contractor familiar with OBC compliance. They can assess your specific space, use case, and moisture conditions to determine the exact tile rating needed.

However, if you are a homeowner with a residential tile question — perhaps you are concerned about slip resistance in a bathroom, kitchen, or entryway where moisture is present — that is something I can help with directly. Residential tile does not have the same prescriptive OBC slip-resistance requirements as commercial spaces, but choosing slip-resistant tile in high-moisture areas like showers and entryways is a smart safety decision for Ottawa homes, particularly given the winter wet tracked in from snow and salt.
