True or False: Doors shall not project into a corridor if it will lessen the 1.20 m minimum unobstructed width required.

The statement is true because building codes establish specific requirements for unobstructed widths in corridors to ensure safety and accessibility. A minimum unobstructed width of 1.20 meters (or approximately 4 feet) is typically mandated to accommodate people, including those with disabilities, moving through the corridor easily. If doors were to project into this space, they could reduce the available width below this requirement, posing hazards such as obstructing safe passage and potentially impeding emergency egress. Therefore, the design of corridors must account for door swing and placement to adhere to these safety and accessibility standards. This ensures that corridors remain clear and navigable, which is crucial in residential and commercial buildings.
