The intent of this <br />rule, though not very clear, is to allow the attachment of awnings and carport~ to the sidewalls of <br />manufactured dwellings. <br /> <br />The proper attachment of an awning or carport should consist of the following: Th~:i~hi~gorlc~6'~i <br />raft should be attached ,w~th lag s~re.w~ d.~recfly.~eaeh...s~.dewal.l stud: (studs are u~uall~ at.I.6 on center). <br />Attachment to the s~&ng only is not acceptable ~ucll we do not recommend attaching rads to sMewall top <br />plates. The single 1" top plates will easily spl~t out from the lag screws and neither 1" or 2" manufactured <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 rules <br />suggest perimeter pier blocking at 8' on center. However, with the increased weight of the newer <br />manufactured dwellings and the add~t,onal roof load from the awmng/carp~;~9~xeenter, would be mote <br />appropriate. All other attachments should be made according to the awnihg/carport manufacturees <br />engineered plans with special attention paid to the top and bottom post connections and ground anchors. <br /> <br />Regarding your question of which takes 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 attention. We are currently in the process o( re-writing the <br />manufactured dwelling rules and will attempt to make this section more clear and more "user friendly." <br /> <br />PATRiCK D.
