(1)(a) Each prefabricated building required to bear an Oregon insignia of compliance must be inspected by the division in accordance with an approved compliance control program in OAR 918-674-0580, the division-approved plans, and the appropriate Oregon Specialty Codes as defined in ORS 455.010. (b) When use of a division inspector is impractical, the division may use the services of an inspector from a local building department to perform inspections of prefabricated buildings. The local inspectors must be certified by the division in the appropriate discipline(s). The division may use local inspectors to perform inspections of prefabricated buildings in the manufacturing facility or at a building site for incomplete structures, or for alterations, conversions and repairs. (c) Except as directed by the division’s building official charged with the administration of the division’s prefabricated structures program, no inspections will be made prior to the approval of plans and issuance of the notice of plan review by the division. No reciprocity inspections will be performed prior to the approval of plans without prior approval from the reciprocal state. The approved plans and notice of plan review must be available to the inspector upon arrival at the manufacturing facility and at the building site when applicable. A manufacturer must provide paper versions of appropriately approved plans when requested by an inspector. (d) All regular inspections must be requested by electronic mail or other methods approved by the division. (e) The division must be notified a minimum of 48 hours prior to the date an inspection is requested for, excluding weekends and holidays, unless a different time for inspection is set by mutual agreement. Out-of-state inspections in locations more than 150 air miles from Oregon require a 21-day prior notice. (2) Inspections performed at a manufacturing facility include, but are not limited to: (a) Cover inspection requires each system constructed to be inspected prior to covering or concealing any portion of the electrical, plumbing, mechanical, fire safety, structural or insulation work. (b) Final inspection requires each system to be inspected after the construction noted in subsection (a) of this section has been covered and prior to the prefabricated building leaving the manufacturing facility. (c) A reinspection is required when corrections necessitating additional work to a particular system or systems of construction are identified following an inspection. It is the responsibility of the manufacturer to request inspections of work not previously approved. Construction must remain open for the purposes of completing required inspections. Any costs or delays associated with opening concealed construction for the purpose of determining code compliance is the responsibility of the manufacturer. (d) Unless specifically approved on a Notice to Local Enforcement Agency form or division authorization sufficiently documented on an inspection report, all construction must be completed and have an approved final inspection prior to a prefabricated building leaving the manufacturing facility. (3) All prefabricated buildings manufactured outside the State of Oregon that are intended for rent, lease, sale or installation in Oregon must comply with the following: (a) Prefabricated buildings manufactured under reciprocity agreements must have division approval and Oregon insignia of compliance attached to the building prior to being shipped to Oregon. (b) Prefabricated buildings manufactured outside of Oregon without a reciprocity agreement must have division approval, may require cover inspections performed prior to leaving the manufacturing facility, and must have an approved final inspection performed by the division when the prefabricated building arrives in Oregon. (c) The division, to ensure that quality control and code compliance is maintained, may make out-of-state inspections as necessary. (4) All prefabricated buildings arriving at the building site in a damaged condition, or damaged during installation, must be visually reinspected in the field by the division. When restoration is complete, a field reinspection is required to validate the division’s initial approval. The manufacturer of the unit is not required to remedy damages or defects caused by persons performing work at the building site not within the control of the manufacturer. (5) Installation inspections of prefabricated structures in Oregon are performed by the local building department where the prefabricated building or prefabricated component building is to be installed, erected, or assembled. (6) Upon written request and payment of required fees the division will perform advisory installation inspections at the building site. Inspection fees are based on hourly rates established in OAR 918-674-0730 and includes travel time portal-to-portal. Inspection fees will be charged to the responsible party after inspections are completed. (7) The division is responsible for inspections of incomplete structures for those construction elements identified on the division-approved Notice to Local Enforcement Agency form designated for inspection by the division at the building site. The division may charge additional inspection fees to cover inspections of incomplete structures. Additional inspection fees are based on hourly rates established in OAR 918-674-0730 and include travel time portal-to-portal. Inspection fees will be charged to the manufacturer after inspections are completed. (8) Complaints must be submitted to the division in writing. The division will notify the manufacturer of all complaints received. (9) The division may conduct unannounced audit inspections at any manufacturing facility to review the manufacturer’s production and compliance control procedures. The division may perform audits of prefabricated buildings at building sites in Oregon. (10) Upon discovery of any violations of the Oregon Specialty Codes or these rules, the division must verify the correction by inspection. If the correction cannot be verified during the initial inspection, the division must make a written report and require the corrective action to be held open for reinspection. If a violation was initially discovered at the manufacturing plant, the correction must be verified before the prefabricated building leaves the manufacturing facility.
