NEIEP Passenger Elevator Door and Entrance Installation (525) Practice Test

Narrow elevator doors are typically found in older or space-constrained buildings due to architectural limitations and the design practices of earlier construction periods. These buildings often faced restrictions in the width of doorways to accommodate factors such as available space and structural elements. As a result, the elevators installed in these structures might have narrower door openings to fit the existing design, reflecting the practical needs of conveying passengers within tight spaces.

In contrast, high-rise skyscrapers and modern office buildings often incorporate wider elevator doors to facilitate the movement of larger groups of people and to meet contemporary standards for accessibility. Commercial warehouses generally also prioritize functionality that allows for larger freight and goods, hence requiring wider access points rather than narrow doors.
