OAR 918-674-0540. Local Building Department Responsibility

(1) Local building departments in Oregon have specified roles and responsibilities for the installation, erection, or assembly prefabricated structures in their jurisdiction. (2) A local building department may not require closed construction to be opened for inspection on a prefabricated building or component bearing an Oregon insignia of compliance. (3) It is the responsibility of the person applying for local building permits for the installation of a prefabricated structure to provide sufficient information to the local building department for the purposes of demonstrating code compliance for the installation of a prefabricated structure at the building site. (4) When a local building department receives a prefabricated building in their jurisdiction the local building department must ensure compliance with the following: (a) The prefabricated building has been approved by the division as evidenced by an Oregon insignia of compliance; (b) The prefabricated building will comply with local regulations at the building site; (c) The prefabricated building will meet the minimum setbacks from property lines and other structures; (d) All fire-resistive occupancy separations and required fire separation walls, parapet walls and other fire-resistive requirements meet the Oregon Structural Specialty Code or the Oregon Residential Specialty Code; (e) Prior to issuing a permit, ensure sufficient information is made available to determine whether the prefabricated building will be installed and used according to its intended design and purpose as identified on the Oregon insignia of compliance; (f) Prior to issuing a permit, ensure sufficient information is made available to determine whether site specific information or local regulations affect the construction or intended use. Information should include, but not be limited to, a site plan, occupancy classification, construction type, structure size, floor live load, roof live load, wind exposure, seismic zone, climate zone, electrical service loads, plumbing fixture loads, number of sections and whether it is a permanent or relocatable prefabricated building; (g) Issue permits and perform plan reviews and inspections of the prefabricated building’s foundation. Foundations and tie-downs for permanently sited or relocatable prefabricated buildings, or the installation of prefabricated component buildings must be designed according to the requirements of the Oregon Structural Specialty Code or the Oregon Residential Specialty Code as applicable. Manufacturer’s installation instructions may be used, provided that they meet or exceed the minimum requirements of the Oregon Structural Specialty Code or the Oregon Residential Specialty Code as applicable; (h) Review plans, issue permits and perform inspections for site-specific, accessibility, geographic, geologic or climatic code requirements affecting the prefabricated building; (i) Issue permits and perform inspections of the electrical, water, gas and sewer connections on and to the prefabricated building; (j) Issue permits and perform inspections of the prefabricated building installations according to the following: (A) If a multi-section prefabricated building, inspect connections at the marriage lines to ensure that such connections are capable of developing a complete load path as required. (B) If an incomplete structure, complete inspection of construction elements on the division-approved Notice to Local Enforcement Agency form that are designated for the local building department to inspect. (k) Issue permits and perform inspections of incomplete structures at the building site when the division has granted prior approval for the local building department to inspect the work on behalf of the division; and (l) Notify the division of any prefabricated building damaged in transit to the building site or during installation so the division may arrange for a damage inspection of the unit. (5) When a local building department receives a project involving prefabricated components, ensure that the prefabricated components have been approved by the division as evidenced by an Oregon insignia of compliance, and compliance with the following where applicable. (a) Issue permits, perform any plan reviews, and perform inspections of the prefabricated component building installations. Inspect connections of the component assemblies to assure that the assemblies are capable of developing a complete load path as required; and (b) Ensure compliance with any applicable provisions in Section (4) of this rule for any prefabricated component building intended to be installed outside of an existing building. (6) Issue a Certificate of Occupancy for prefabricated buildings and prefabricated component buildings after the installation is complete.
