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.
Residential building codes vary substantially from municipality to municipality and should be checked locally, but at minimum a hallway width should be no less than 36 inches.
The minimum hallway width in a residential building is typically 36 inches (3 feet) according to many building codes. This width allows for safe passage, including for individuals with mobility aids.
