Massachusetts Unrestricted Construction Supervisor License Practice Test

In a business use group with a gross floor area of 10,000 square feet, what is the minimum required door width?

1. 28 inches

2. 30 inches

3. 32 inches

4. 34 inches

The correct answer is: 32 inches

In a business use group that has a gross floor area of 10,000 square feet, the minimum required door width is influenced by accessibility standards and safety regulations. For buildings of this size, the Americans with Disabilities Act (ADA) requires that doors be wide enough to accommodate individuals who may be using wheelchairs or other mobility aids. The standard minimum clear opening width for doors in accessible buildings is typically set at 32 inches when the door is in the open position. This requirement ensures that all individuals can enter and exit the building comfortably and safely, which is especially important for public buildings. Door widths smaller than this could impede access, violating both accessibility standards and safety protocols. The other options do not meet the 32-inch minimum requirement outlined in building codes and regulations aimed at ensuring accessibility for all.
