OBC DIVISION B · PART 3 · SECTION 3.2 — FUNCTIONAL STATEMENTS / BUILDING FIRE SAFETY

What are the fire department access route requirements under the Ontario Building Code?

Buildings must be served by a street or an access route designed for fire department vehicles, located to bring firefighters close to the principal entrance and to hydrants, with clear width, overhead clearance, gradient and load capacity suitable for fire apparatus.

Code reference
Every building must face a street or be provided with access routes so fire department vehicles can reach the building, the principal entrance and firefighter connections. Access routes must meet design criteria for width, centreline location relative to the building face, overhead clearance, turning, gradient and all-weather load-bearing surface, and connections for hydrants and siamese fittings must be kept accessible.
OBC Division B, Subsection 3.2.5.

What this means in practice

Access routes are a frequent site-plan coordination issue: landscaping, canopies, bollards and parking layouts often conflict with required clearances and turning paths. High buildings and unsprinklered buildings face stricter access expectations, and the location of the fire department connection must suit hose lengths from the route. Engage the local fire service early, since municipalities interpret route geometry and hydrant spacing differently and late changes can reshape the site plan.

Plain language

Fire trucks need a real path to the building, strong enough to drive on, wide and tall enough to pass, and close enough to the front door and hydrants. Site designs have to leave that route clear year-round.
