The intent of this <br />rule, 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 consist 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 />Attachmant to the siding only is not acceptable and we do not recommend attaching rails to si4ewall top <br />plates. The single 1" top plates will easily split out from the lag screws and neither 1~ or 2" manufact~ired <br />dwelling top plates ~re 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 pier blocking at 8' on cantor. However, with the' inareas.~e~.,~,W,o!g~,,.,,t 0,~the newer <br />tmmufactured'dwellings and the add~onal roof Bad from tho awning/carpOrt, 4' on eentox would be more <br />hppropriate., All other attachments should bo made according to the awning/carport manufacturer's <br />engineered plans with special attention paid to the top mci bottom po~t connection~ and ground anchors. <br /> <br />Regarding your question of which take~ pre~edene~ for the attachme, ut of accessory structures to <br />mangfaglur*d dwellings (manufactured dwelling manufacturer's installation instructions vs. Oregon <br />Spe~/~ty ~odes);'the.
