Do Ottawa fire codes have specific requirements for commercial epoxy flooring

Ottawa Fire Code and Commercial Epoxy Flooring

Ottawa's fire code requirements for commercial epoxy flooring fall under the Ontario Fire Code (O. Reg. 213/07) and the Ontario Building Code (OBC), which together regulate flame spread and smoke development ratings for interior finishes in commercial buildings. Standard epoxy floor coatings applied at typical thicknesses of 10 to 30 mils are generally compliant for most commercial occupancies without special testing or certification. However, there are specific scenarios where fire code requirements become a real factor in your system selection.

The OBC classifies interior floor finishes differently from wall and ceiling finishes, and floors have less stringent flame-spread requirements because fire behaviour on horizontal surfaces differs significantly from vertical ones. For most commercial occupancies — retail, office, warehouse, and light industrial — a standard 100 percent solids epoxy or polyaspartic coating meets code requirements without issue. The concern arises in high-hazard occupancies such as facilities storing flammable liquids, certain manufacturing environments, and buildings with specific fire-rated assemblies where the floor finish contributes to the overall fire resistance rating.

Where fire codes matter most for Ottawa commercial epoxy projects is in assembly occupancies (restaurants, event spaces, fitness facilities) and institutional occupancies (healthcare, education). In these classifications, the City of Ottawa's Building Code Services may require documentation that the floor coating system meets CAN/ULC-S102.2 flame spread and smoke development standards. Most major commercial epoxy manufacturers — companies like Sika, BASF MasterSeal, and Rust-Oleum Industrial — publish test data for their systems showing compliance with these standards. Your contractor should be able to provide the technical data sheets confirming the specific products meet the required flame spread index (typically under 200 for floors) and smoke development classification.

There are two additional fire-code-adjacent requirements Ottawa business owners should know about. First, if your epoxy floor installation involves modifying or penetrating a fire-rated floor assembly — for example, routing new floor drains through a concrete slab that serves as a fire separation — a building permit is required and the fire rating must be maintained. Simply applying a coating over the existing slab surface does not affect the fire rating. Second, commercial kitchens and industrial facilities that handle flammable materials may need static-dissipative or conductive epoxy flooring to prevent electrostatic discharge that could ignite vapours. These specialized systems cost $15 to $22 per square foot in Ottawa but are non-negotiable where flammable atmospheres exist.

For straightforward commercial spaces like retail stores, offices, and warehouses, fire code compliance is rarely a problem with standard commercial epoxy systems. If you are unsure about your specific occupancy classification, call Ottawa's 3-1-1 service to confirm requirements before starting the project. An experienced commercial flooring contractor will also understand these requirements — you can find contractors with commercial experience through the Ottawa Construction Network directory at justynrookcontracting.com.
