Having reliable access for fire apparatus on two sides of a four-story-or-higher facility ensures that crews can position ladders, hoses, and equipment from multiple directions and still operate in adverse weather. The idea is to prevent being blocked or limited by one approach, which could hinder rescue and suppression operations if snow, ice, or parked vehicles obstruct a single side.

Two sides provide adequate maneuvering space for turning, placing an aerial device if needed, and establishing water supply and backup routes without needing to encircle the entire building. One side alone can leave a critical area blocked or constricted, delaying actions. Requiring access on two sides is the minimum to support safe, effective emergency operations in all-weather conditions.

Three or four sides would go beyond the minimum, and may be required by specific site constraints or code provisions, but the standard baseline for new facilities four stories and higher is two sides.
