What is the minimum width requirement for a doorway in a residential building?

In residential building codes, the minimum width requirement for a doorway is typically set at 32 inches. This standard is in place to ensure accessibility, especially for individuals using wheelchairs or other mobility devices. A doorway of this width allows enough space for people to pass through comfortably while accommodating various mobility aids.

Having a doorway that is at least 32 inches wide also aligns with the guidelines established by the Americans with Disabilities Act (ADA), which aims to promote accessibility in all public and private spaces. This width reduces any potential for obstruction or difficulty in navigating through, particularly in emergency situations.

While other widths, such as 28 inches, 30 inches, and 36 inches, can be used in specific circumstances or specific types of buildings, 32 inches remains the recognized minimum that balances usability and accessibility in standard residential design.
