To keep City of Portland building permit customers up to date on State of Oregon Building Code application submittal requirements, the Bureau is providing the following advance summary and notice of training opportunities for applicants submitting residential building permits for new structures and additions designed using prescriptive wall bracing.
On October 1, 2011, all applications for new residential structures and additions designed using prescriptive wall bracing will be required to meet the new application requirements of the 2011 Oregon Residential Specialty Code (ORSC). The additional information required by the 2011 ORSC will include separate Wall Bracing Floor Plans, a Building Construction Narrative, and Braced Wall Calculations.
The prescriptive wall bracing requirements of the 2011 ORSC have been completely rewritten and expanded from six (6) pages in the 2008 ORSC to thirty (30) pages of text, figures and tables. While the final design of a residential structure may turn out to be very similar, the code terminology and methods to determine minimum wall bracing requirements are entirely new.
The Bureau of Development Services (BDS) Handout, Applying for a New Single Family Residential Project will be updated to reflect the new submittal requirements.
Note: The 2011 ORSC was effective on July 1, 2011 with a three month grace period where the applicant may choose to comply with either the 2008 ORSC or the 2011 ORSC.
