What makes an occupant garage door deficient?

A deficient occupant garage door is one that fails to meet specific safety and building standards. For a garage door to be considered adequate for its purpose, it needs to adhere to several criteria that ensure a certain level of fire resistance and structural integrity.

One of the primary requirements is that the door must typically be solid wood if it's a door installed between a garage and living space because solid wood doors provide better fire resistance. Additionally, the thickness of the door is crucial; a standard thickness of at least 1 3/8 inches ensures that the door meets the necessary performance benchmarks for durability and fire prevention. Furthermore, the door should have a fire rating of at least 20 minutes, which helps prevent the spread of fire and smoke from the garage to the living areas of the home in the event of a fire.

When all these criteria are combined, they highlight why each individual factor contributes to the overall assessment of a garage door's adequacy. If any of these specifications are not adhered to, it leads to a door being classified as deficient, hence the choice that includes all the mentioned characteristics as indicators of deficiency is accurate.
