The intent of this <br />role, though not very clear, is to allow the attachment of awnings and carports to the sidewalls of <br />manufactured dwellings. <br /> <br />The proper attachment of an awning or carport should consi,t of the following: The awning or carport <br />rail should be attached with lag screws directly to each sidewall stud (studs are usually at 16" on center). <br />Attachment to the siding only is not acceptable and we do not recommend attaching rails to sidewall top <br />plates. The single 1" top plates will easily split out from the lag screws and neither 1" or 2" I~anufactured <br />dwelling top plates are designed to transfer the roof live loads of the manufactured dwelling or the <br />awning/carport to the studs. To transfer the loads from the sidewall studs to the ground, the current roles <br />suggest perimeter p~er blocking at 8' on center. However,~.wtth.:the..mereese~l;:We~ght.'of:the newer <br />manufa~; dwellmg~ and the attdmonal rooflo~ from the awning!carport~ 47 on center' would be more <br />appropriate. All other attachments should be made according to the awning/carport manufacturer's <br />engineered plans with special attention paid to the top and bottom post cormectiom and ground anchors. <br /> <br />Regarding your queotlon of which takeo precedence for the attachment of accessory structures to <br />manufactured dwellings (manufactured dwelling manufacturer's installation instructions vs_ Oregon <br />Specialty Codes), the Oregon Specialty Codes take precedence. <br /> <br />Thank you for bringing this issue to my att.e, ntion. We are currently in the process of re-writing the <br />manufactured dwelling rules and will attempt to make this section more clear and more "user friendly." <br /> <br />PATRICK D.
