The Ontario Building Code | Covered Vehicular Passageway
3.2.3.18. Covered Vehicular Passageway
(1) A covered vehicular passageway designed as a receiving or shipping area shall be separated from every building or part of a building adjoining it by a fire separation having a fire-resistance rating not less than 1.5 h.
(2) A covered vehicular passageway constructed below grade shall be of noncombustible construction.
In Plain Language
This clause sets requirements for exterior wall construction and cladding materials specifically tied to the limiting distance calculated for spatial separation, since combustible cladding may be restricted where a wall's rating and closeness to a property line demand added protection.
