Question

An egress window must have an unblocked open area no less than ______sq ft, except those on grade floor openings. These must have an open area of no less than ______sq ft.

Answer 1

Egress windows must have a minimum unblocked open area of 5.7 sq ft, or 5 sq ft for grade floor windows, subject to local building codes.

Step-by-step explanation:

The question pertains to egress window requirements, specifically the minimum open area necessary for safety and code compliance. For egress windows not located on the grade floor, the minimum unblocked open area must be at least 5.7 square feet. However, for egress windows located on the grade floor, the unblocked open area must be no less than 5 square feet. It's important to note that these measurements can vary slightly depending on local building codes, but these figures are a general standard recognized in many building codes for residential construction.
