What is the minimum width of at least one exterior door serving a residence?

• A. 28 inches
• B. 30 inches
• C. 32 inches
• D. 36 inches

Answer: (C)

The minimum width of at least one exterior door serving a residence is typically set at 32 inches. This standard is established to ensure accessibility, particularly for individuals using wheelchairs or other mobility aids. A 32-inch door allows for easier navigation and movement for all occupants, aligning with building codes that prioritize safety and inclusivity. Choosing a wider door, like 36 inches, provides even more accessibility features but may not be required by all building codes. Options that propose widths smaller than 32 inches, such as 28 or 30 inches, do not meet the standard for accessibility and could limit the usability of the doorway, especially in emergency situations when larger access is crucial. The 32-inch width strikes a balance between being functional and meeting the necessary code requirements.
