§ 4.4.5.2. Attic Exemptions:
Sufficient exhibits must be submitted within the plan set demonstrating compliance with Board of Adjustment decisions and Title 25-2 Subchapter F. The following minimum items are required for review of exempted attics:
1)
The building elevations must clearly depict (and label) the slope of the roof(s) for the habitable attic area along with depicting that acceptable construction for a habitable attic is being followed.
2)
Provide a separate roof plan within your architectural plan set with all roof slopes identified (labeled) on it.
3)
The floor plans and building elevations must depict that the habitable attic is contained with the roof structure and does not extend beyond the footprint of the floors below.
4)
A separate floor plan and a section view of the habitable attic must be submitted depicting compliance with the Board of Adjustment interpretation from January 9, 2012 (C15-2011-0110) regarding: "As measured in accordance with Subsection 3.3.4, fifty-percent (50%) or more of the exempted portion of an attic must have a height of less than 7 feet, but more than 5 feet." Both exhibits (floor plan and section view) shall depict the attic areas that are: 1) less than 5 feet of ceiling height, 2) between 5 feet and just less than 7 feet of ceiling height, and 3) 7 feet and greater in the ceiling height. In addition, a tabular calculation based on the exhibits must be included demonstrating a valid ratio (expressed in sf or %) for a habitable attic exemption (i.e. the area with ceiling heights between 5' and less than 7' is greater than the area with ceiling heights 7' and greater).
