Bureau of Development Services <br /> Program Guide—Solar Water Heating and Photovoltaic Electric Generators <br /> Installed on One or Two Family Dwellings <br /> Page 6 of 14 <br /> December 1, 2010 <br /> http://www.portlandoregon.gov/bds or contact the FIR program directly at <br /> 503-823-7784. <br /> C. Permit Submittal Requirements <br /> Regardless of the permit application process, the following information shall be <br /> submitted for each permit. <br /> 1. Site Plan <br /> A site plan is required showing building footprints, property lines, location and <br /> dimensions of solar collectors, ridgeline of roof, fire fighter access and a <br /> description of the solar system. The system must be shown in sufficient detail <br /> to assess whether requirements of section 304.9 or one of the exceptions of <br /> OSISC have been met. See attached Figure #4. <br /> 2. Elevation Drawings <br /> A simple building elevation will be required to measure the height of the <br /> installation above the roof. The elevation must show the height of the <br /> building, and the height of the solar installation, but does not need to show <br /> other building details, unless a Design Review is required. See attached <br /> Figure #3. <br /> 3. Structural Plans <br /> a. Prescriptive system If the system meets all the prescriptive <br /> requirements of the OSISC, no structural calculations will be required. <br /> However, a simple structural plan showing the roof framing and system <br /> racking attachment details are required. See figures 1 through 4 for <br /> sample drawings. In addition, complete and attach the checklist for <br /> prescriptive installations found at the end of this document. <br /> b. Designed system <br /> 1) If the system does not qualify for the prescriptive path, then structural <br /> calculations prepared by an Oregon registered engineer are required. <br /> At a minimum, structural calculations verifying adequacy of the <br /> structure's roof framing, strut or frame supporting the rails (where <br /> used), attachment of the rail to the support/strut frame and the <br /> attachment to the building's roof framing are required. Calculations <br /> must be based on the latest version of the Oregon Structural Specialty <br /> Code. In some cases, manufacturer's information and installation <br /> details may be substituted for required calculations and details <br /> 2) Drawings shall include a roof framing plan (member size, type, span <br /> and spacing) and any additional framing required to reinforce the <br /> existing framing. The plans should include the layout of the module <br /> system and its mounting points. Drawings should also provide <br />
