Customers must contact their local permit authorities to find out the permits and approvals they need and the building code and design load specifications required to obtain their permits. Kodiak Steel Homes® is not responsible for determining your permit requirements or guaranteeing that the house you purchase will meet them; you are. Listed below are sets of code and load specifications that most Kodiak Steel Homes® models will meet. When customers order a home, they must choose one of the available sets of specifications. We can then provide construction plans to be submitted to the permit office that are stamped with the seal of an engineer licensed in the state where the home is to be constructed, certifying that the design of the home meets the requested specifications.
*Most codes (notably the IBC) call for a "ground snow" specification. The more commonly known "roof snow load" is not actually specified by the code but can be derived by multiplying the ground snow by a particular value, usually 0.7 (for example a ground snow of 57 psf equals a roof snow load of 40 psf). The term "live load" is typically misapplied (even by building inspectors) and actually refers to the weight of a "live" body on the roof, e.g. a person performing maintenance. Virtually all applicable codes specify a 20 or 21 psf live load. Usually when someone refers to a "live load" above 20 psf, they are actually referring to the roof snow load.
Building codes require that rated design loads are meant to be applied concurrently. This means, for example, that a Kodiak Steel Homes® model designed to the first set of specifications listed above is rated to withstand a 140 mph burst of wind during a minor earthquake while the roof is covered with 20 lbs. of snow per square foot. That does not mean that the home is guaranteed to survive this set of environmental conditions in the real world, only that it meets the International Building Code's criteria for this rating.
