For wheelchair access in an office building, hallways must typically be at least 36 inches wide to accommodate a standard wheelchair. However, if the hallway is a high-traffic area or requires turning space, it should be wider, ideally 60 inches, to allow for maneuvering and safe passage. Compliance with local building codes and the Americans with Disabilities Act (ADA) is essential for ensuring accessibility.
Building codes for a single family dwelling typically require hallways to be a minimum of 3 ft (36 inches) in width. A hallway that is 5 ft (60 inches) in width comfortably allows for the passage of two people. As a side note, the width of a typical wheelchair is 22 inches.

To build a concrete ramp for wheelchair accessibility, the specifications typically include a slope of 1:12 (1 foot of ramp for every 12 feet of horizontal distance), a minimum width of 36 inches, handrails on both sides, a non-slip surface, and a level landing at the top and bottom of the ramp. These specifications ensure safe and easy access for individuals using wheelchairs.
Assuming that the hallway is 30 m long. 30mx100= 3000 cm . Then divide 3000 cm by 2,54= result: 1181,1023622047244094488188976378 in = (Firstly you have to use any measuring tool to find the length of the hallway in meters, or you may get the final reading in inches if the measuring tape tool has divisions in centimeters and inches. Usually they have divisions on foot and cm)
The minimum access size opening allowed for a crawl space typically ranges from 16 inches by 24 inches to 18 inches by 24 inches, depending on local building codes.
