What is the common minimum width for a residential hallway to ensure safety and accessibility?

The common minimum width for a residential hallway that ensures safety and accessibility is typically 36 inches. This width is recommended to allow for safe passage, not only for individuals walking but also for those who may be using mobility aids such as wheelchairs or walkers. In many building codes and standards, including those influenced by the Americans with Disabilities Act (ADA), a 36-inch width is considered the bare minimum to accommodate accessibility needs effectively.

A narrower width, such as 30 inches, may not provide sufficient space for individuals with disabilities, potentially creating hazards and obstacles in the event of an emergency. Wider hallways, such as those at 42 inches or 48 inches, while beneficial for comfort and accessibility, exceed the minimum requirements and may not be necessary in all residential configurations.

Therefore, specifying 36 inches as the minimum aligns with safety guidelines and accessibility standards, ensuring that residential spaces are functional and accommodating for all users.
