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 bo attached with lag screws directly to each sidewall smd (studs arc 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 eo~ily split outYrom 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 rule* <br />suggest p~rimeter pier blocking at 8' on center. However, .w.!~.: .w..~igk. t.gf...,the newer <br />.mapufaetm:ed'dWolliags ami the ai:Iditional mol load from thc awuiag/~6~t, 4* '~h ~ter would be more <br />appropriate.. All other attaelanents should be made according to the awuing/earport manufacturer'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 tak~ p~ecadence for the atrovent of accessory structures to <br />manufactured dwellings (manufactured dwelling manUfaCturer's installation instructions vs. Oregon <br />Specialty Codes), the Oregon. Specialty Codes take:.preeedence. <br /> <br />Thank you for bringing this issue to my allentioai, We are currently ia the process of re-writing the <br />manufactured dwelling rules and will attempt to make this section more clear ami moro "user friendly." <br /> <br />PATRICK D.
