A. The applicant may include design options within the context of the base plan. Design options are limited to:

B. Each option must be submitted on a separate plan sheet and must include any required structural changes and the supporting calculations, including the lateral and gravity load resistance system, stamped by the designer responsible for the engineering of the plans.

C. Base plans are limited to those structures within the scope of the International Residential Code (IRC). Elements of structures falling outside of the prescriptive design requirements of the IRC such as lateral wall bracing, foundation systems, and other structural provisions require an engineered design. Engineered design criteria may vary depending on site location for wind exposure, seismic ground motion and acceleration, and soil types. All designs shall address the most conservative assumptions for the Gig Harbor area or the base plan may be limited to use in sites meeting the design criteria.
