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: ,Tl3,.e.:awning or carport <br /> rail should be attached with lag screws directly to each sidewall stud (studs are usually at 16" on conter)~ <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 e~ily split out from the lag screws and neither I" 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 additional roof load from the awning/carport ~_ ,..,, ,~. r;~0tfl'd:,be;more. <br /> appropriate, All other attachments should be made according to the awning/c~:;3~: manufa~'S <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 installatioh 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 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.
