Standard Comments Checklist

November 2012 Standard Comments Checklist Scope: Prescriptive 2500 square feet, conventional light frame wood construction, single family dwelling Red Text = Specific code requirements based on design criteria This Standard Comments Checklist is provided to assist the applicant with assembling a comprehensive set of plans that will result in their project moving smoothly through the plan review process in the least amount of time. The requirements captured within this checklist are relevant to most residential projects but should not be considered exhaustive. Providing the items identified will aid in both the predictability and timeliness of the plan review process. This list represents the provisions of the State of Oregon Residential Specialty Code (ORSC), 2011 Edition, based on the 2009 International Residential Code. Liberties have been taken with Code language for sake of readability. If exact code text is required, see referenced code sections.
