(1) Except where otherwise specifically stated in these rules, all prefabricated construction must be designed to comply with the applicable specialty codes listed below: (a) The Oregon Structural Specialty Code; (b) The Oregon Mechanical Specialty Code; (c) The Oregon Plumbing Specialty Code; (d) The Oregon Electrical Specialty Code; (e) The Oregon Elevator Specialty Code; (f) The Oregon Boiler and Pressure Vessel Safety Specialty Code; (g) The Oregon Residential Specialty Code; and (h) The Oregon Energy Efficiency Specialty Code. (2) Additions, alterations, conversions or repairs to prefabricated buildings are subject to the code requirements of this rule. (3) When it can be demonstrated that compliance with strict requirements of the Oregon Structural Specialty Code are impractical and the intent and purpose of the code can still be met without causing structural failure or risk of fire in specific use structures, the requirements of the code may be modified by the division’s building official charged with administration of the division’s prefabricated structures program through an approved alternate method or materials application. (4) Equipment protection-only structures are exempt from all of the envelope requirements of the Oregon Energy Efficiency Specialty Code.
