What do I need for an electrical panel permit in Oregon?

Why panel work needs a permit

Whether you are adding a circuit, replacing a service panel, or upgrading to support a new appliance, most panel and service work in Oregon requires an electrical permit. A permit is not a rubber stamp. It is the mechanism that gets your electrical work inspected against the National Electrical Code and local Oregon standards, so a second set of qualified eyes confirms it is safe before it is buried in a wall or energized for years.

Beyond safety, a permit protects you in practical ways: it keeps the work up to code, helps preserve your homeowner's insurance coverage, and makes the home easier to sell later, since unpermitted electrical work is a common sticking point in inspections and appraisals. Whenever we handle a panel upgrade or similar work, we pull the permit and coordinate the inspection as part of the job.

1. Verify panel location and clearance (NEC 110.26)

Inspectors need safe working space around the panel, and this is one of the first things they check. The code calls for clear room in front of and around the equipment so an electrician can work on it without hazard.

• Depth: at least 36 inches (3 feet) of clear space in front of the panel
• Width: at least 30 inches, or the width of the panel, whichever is greater
• Height: at least 6.5 feet of clear headroom
• Keep the space free of plumbing, gas lines, shelving, and stored items

2. Identify your service type

Know what you have before you apply. The permit and the work both depend on how your home is fed and at what capacity, so identify these details up front.

• Overhead or underground service
• Service size: 100-amp, 150-amp, or 200-amp (larger for some homes)
• Single-phase (typical for homes) or three-phase (larger properties)

3. Confirm grounding and neutral arrangement

Grounding is central to preventing shock, and it is a standard inspection item. Depending on your home, the work may involve grounding electrodes such as ground rods or plates, a properly arranged neutral and ground at the main service, and a grounding connection to metal water piping where it applies. Getting the neutral and ground arrangement right, connected at the main service, kept separate in any subpanel, is exactly the kind of detail an inspection is there to catch.

4. Include a load calculation

Inspectors want confidence that your panel can safely carry your home's demand. If you are adding circuits or large loads such as an EV charger, a hot tub, a kiln, or a heat pump, include an updated load calculation with the application. The same calculation tells you whether your existing service has room or whether an upgrade is part of the project, which is why it is worth doing early rather than discovering a capacity problem mid-job.

5. Apply, then prepare for inspection

Electrical permits are issued by your local city or county building department, and most can be applied for online. In this area that usually means the City of Portland Permitting & Development (formerly the Bureau of Development Services), Washington County Building Services, or the City of Beaverton, depending on where you live. Larger service upgrades also involve coordinating with your utility, PGE or Pacific Power, for a temporary shutoff.

One Oregon note worth understanding: homeowners can pull a permit for work on their own owner-occupied home, but panel and service work involves live equipment that stays energized even with the main breaker off, and a mistake can be fatal. For anything beyond the simplest tasks, having a licensed electrician do the work, and carry the permit, is the safer path. We handle the permit, scheduling, inspection prep, and utility coordination so the process stays smooth.
