Projections are prohibited in the clear width of a door if they are below how many inches?

When considering the clearance requirements around doors, particularly for accessibility and safe egress, projections must not intrude into the clear width of a door opening. This is crucial to ensure that individuals, especially those with disabilities, can navigate through the doorway without obstructions.

The correct threshold for when projections can interfere with the clear width is 34 inches. Anything below this height can significantly impede a person's ability to maneuver through the door. For instance, if protrusions lower than this height were allowed, they could create hazards or barriers, particularly for individuals using mobility aids like wheelchairs or walkers.

Understanding the context of this requirement is essential as it relates to compliance with building codes and accessibility standards. Ensuring that the clear width is maintained above this threshold helps create safer environments in commercial buildings, aligning with regulations such as the Americans with Disabilities Act (ADA). By adhering to the 34-inch rule, building inspectors can help ensure that doorways remain accessible to everyone.
