The attic is the 2nd story of my home and has normal stairs going up from the main floor living space.
Outside access to my attic.
Hot air exhaust vents located at the peak of the roof allow hot air to escape.
But they do not mention or prohibit exterior access to the attic.
Intake vents located at the lowest part of the roof under the eaves allow cool air to enter the attic.
Attic accesses are required for any attic that has a clear ceiling height of 30 inches or more and the opening needs to be a minimum of 22 inches by 30 inches in size.
