establishes the general requirement that all bedrooms must have at least one window that is large enough to be used as an exit in an emergency. Emergency Escape: An Emergency Escape requires that each bedroom must have a door that leads directly to the exterior of the building or have a properly-sized egress window that can be opened from the inside without the use of keys, tools, hardware or special knowledge (unless this bedroom has a sprinkler system installed).Ventilation (at least 0.28m² or 3 ft² or an adequate year-round mechanical ventilation).Light (at least five per cent of the floor area served).
