Memo To: From: CC: Date: Re: Building Codes Appeals Board ~~ Debbie S. Wilmore, Chief Building Official Mark Huber, Deputy Building Official August 2, 2007 Protection of Openings in Windbome Debris Regions In the 2006 Edition of the Residential Code for One-and Two-Family Dwellings, Section 301.2.1.2 addresses protection of openings in windbome debris regions. Based on the code definition, our entire city will be considered a windbome debris region, since our basic wind speed will be going from 115 mph to 120 mph with the adoption of the new code. The section requires that builders of new residential structures provide pre-cut, wood structural panels (minimum 7/16" and maximum 8' span) for attachment to framing of openings. In addition, this section also requires the builder to provide the attachment hardware for said panels. For the Board's convenience, we have included the definition, code section and "an example" of attachment hardware (plylox Hurricane Window Clips). Staff reviewed the code requirement and discussed plan review, inspection checklist changes and field inspection procedural changes for implementation. We estimate cost impact to the builder of$I,500 but believe the code requirement to be a positive one. Implementation could occur as follows: . Development of an Informational Handout for builders/citizens. . Amend job inspection checklist form to require confirmation that the proper number of wood panels and panel clips are on the lob site prior to the release of electricity. If the Board feels leaving this requirement in place is appropriate, the requirement would simply be implemented along with the code adoption. If the Board feels the extra requirement is not warranted, this section would need to be deleted from the code at the time of adoption. We would appreciate a recommendation from the Board.
