Building Codes

Special precautions must be taken with electrical wiring in the above types of buildings because of dust from feed and litter and corrosive agents associated with animal confinement. Buildings constructed under the "Agricultural Exempt" building status (no building permit required) that are used for the above purposes must also comply with the following requirements. Milking parlors and areas where livestock may come in contact with metallic equipment have additional requirements including Equipotential Planes and require electrical plan review prior to construction.

• Barns, Riding Arenas and buildings which provide animal habitat, animal care or feed storage are subject to National Electrical Code Article 547 – Agricultural Buildings. Wiring methods, equipment and light fixtures must be of an approved type for the environment where they are installed. Areas requiring special attention are those where excessive dust and dust with water may accumulate, damp or wet locations and corrosive atmospheres. Generally, this requires a wiring method which is suitable for damp or wet locations. All wiring subject to physical damage shall be protected. Nonmetallic sheathed cable (Romex) is not an approved wiring method for animal habitat, animal care or feed storage areas. NEC 547.5
• Electrical distribution panels should be located in tack room or other area away from animal habitat and feed storage to protect overcurrent devices from dust and moisture or will require a NEMA 3R rated enclosure suitable for wet locations. NEC 547.6
• Separate equipment grounding conductor required. Non-current carrying metal parts of equipment, raceways and other enclosures must be grounded by a copper equipment grounding conductor to equipment. If installed underground, the equipment grounding conductor shall be insulated or covered. NEC 547.5(F)
• In areas separated from animals and feed storage, Nonmetallic sheath cable (Romex) can be used where not subject to physical damage. Exposed nonmetallic sheathed cable shall be protected where it is installed horizontally below 8 feet above the floor. Exposed nonmetallic sheath cable below 8 feet above the floor that enters the top and bottom of a panelboard shall be protected from physical damage by conduit, ½ inch plywood or ½ inch drywall, per Oregon Electrical Specialty Code amendment to NEC 334.15(B).
• Luminaires (lighting fixtures) shall be installed to minimize the entrance of dust, foreign matter, moisture and corrosive material. Generally, luminaires of this type are those suitable for damp or wet locations. Luminaires exposed to physical damage shall be protected by suitable guards. NEC 547.8
• Wiring, luminaires and equipment in a wash area must be approved for wet location. NEC 547.8
• All 120 volt, 15 and 20 amp receptacle outlets installed for personnel require GFCI protection except commercial installations. NEC 210.8(A)(2).

Inspection requests must be received before 6 a.m. the day of the inspection. You may ask for an inspection by calling the Inspection Request Line at 503-742-4720. We do not make appointments, but do attempt to honor requests for morning or afternoon inspections. Because of the uncertainties in the amount of time required, however, we cannot guarantee a specific time of day. If the dwelling is occupied, the applicant or an adult must be present to let in the inspector and remain during the inspection.

Inspection Codes

Under ORS 455.315, some buildings used for agricultural (including marijuana), forest or equine uses can be exempt from the building code. So is this the right approach for your project? The information below provides some items to consider in making this decision. It is also important to know that the first step in determining if an Ag Exemption is right for your project is to identify the land use zone your land is in. The property must be zoned for farm or forest use, as required by State Statute, in order to qualify for an Ag Exemption.

Things to consider when getting a permit

• With a permit, your building is not subject to the limitations of Ag Exempt structures. For example, you can have the public in the structure and you are not limited to a maximum of 10 people in the non-plant growing areas of the building.
• Getting a permit could save time in the long run. Obtaining a permit on a previously exempt structure can involve hiring a registered design professional, upgrading the structure so it meets the current code requirements and opening areas of the building so building elements can be inspected. If you plan to eventually get a permit for your building, starting with a permit may save time and money.
• If you obtain a permit, all fees are assessed — including costs beyond building permit fees, like system development charges (SDCs), school excise taxes and state surcharges. In some cases, these fees can equal or exceed the project permit fees. Talk with your plans examiner to determine the full extent of the fees that will be involved.

Things to consider when choosing an Ag Exemption

• Your project will be exempt from obtaining a building permit or building-related inspections.
• System development charges (SDCs) are not assessed for Ag buildings.
• Land use approval, mechanical, electrical and plumbing permits are still required;d all inspections must be obtained.
• The building cannot be used by, or open to, the public.
• You are limited to only 10 people in the building at any one time, except in areas containing the plant growing operations.
• If you choose to convert an Ag Exempt building to a permitted structure, additional work will be needed. This may include hiring an engineer to evaluate whether the building meets code requirements, performing modifications to the structure so it is in compliance with code or opening the existing structure to expose building elements for inspection.
• Any building using a forestry Ag Exemption can never be converted to a permitted structure.

The Oregon Building Codes Agency has adopted rules to create uniformity for Electrical Plan Review requirements.

Time in review

Electrical plan reviews should be approved or denied within 10 working days from the receipt of the complete electrical plans. If denied because of deficiencies, written notification will be given. Upon re-submission, the 10 day review time starts again. When the complexity or size of a project requires more than the 10 working days, we will notify the permit holder of needed time for completion. When plans have been submitted with proper electrical application, Clackamas County will issue a permit number and may allow limited courtesy inspections to prevent construction delays.

Plan review standards

Review is required for any of the following:

1. Ampacity:
   1. A service or feeder beginning at 400 Amps where the available fault current exceeds 10,000 Amps at 150 Volts or less to ground or exceeds 14,000 Amps for all other installations.
