Electrical Permits in North Idaho: What Homeowners Need to Know Before Upgrading

Any panel upgrade, service change, or new circuit work in Bonner or Kootenai County needs a permit. This includes swapping a 100-amp panel for 200-amp service, adding a generator interlock, wiring an EV charger circuit, or running new circuits for a shop or addition. Small stuff like replacing a light fixture or an outlet on an existing circuit usually doesn't need one. Anything touching the panel, service entrance, or adding new circuits does.

The permit gets pulled before work starts, not after. Your electrician handles this in most cases. It gets filed with the county building department, and for panel upgrades, the utility (Avista or Kootenai Electric, depending on where you are) also needs to know since they may need to coordinate the meter or service drop.

Why the permit matters more than people think

A permit means a licensed inspector checks the work before it gets covered up or energized. For a panel upgrade, that's grounding, bonding, breaker sizing, and clearance around the panel. For a new circuit to a garage or shop, it's wire gauge, breaker match, and box fill.

Skipping the permit doesn't just risk a fine. It can void your homeowner's insurance if there's ever a fire traced back to unpermitted work. It also becomes a problem at resale. Appraisers and buyers' inspectors ask about permit history on panel upgrades. An unpermitted 200-amp service can hold up a sale or force you to redo the work with a permit anyway, after the wall is already closed up.

What triggers a permit in this area

• Panel upgrades from 100-amp to 200-amp service, common when adding a whole-home generator, EV charger, or second heat pump

• New circuits for appliances like a hot tub, well pump, or shop equipment

• Generator infrastructure including transfer switches and interlock kits tied into the main panel

• Service relocations, common on older cabins where the meter and panel need to move for a remodel

• Sub-panels added for detached garages, guest cabins, or barns

Simple like-for-like replacements, such as swapping a breaker for the same amperage or replacing a damaged outlet, generally don't need a separate permit. When in doubt, ask before starting. It's a five-minute phone call to the county or your electrician.

What the inspection process looks like

Once the permit is pulled, the work happens with the panel or wiring exposed for the inspector to see. This means walls stay open until sign-off, which matters if you're coordinating with drywall or a remodel schedule.

Bonner County and Kootenai County both use rough-in and final inspections for larger jobs. A panel upgrade usually needs one inspection after the new panel is installed and before the meter gets re-energized by the utility. Smaller jobs like a single generator inlet might only need a final inspection.

Turnaround time for scheduling an inspection runs a few days to about a week, depending on the season. Spring and early summer get busier as people prep for storm season and generator installs. Winter has less competition for inspector time but weather can delay outdoor panel work.

What it actually costs, permit included

Permit fees themselves are a small piece of the total cost, usually under $200 depending on the scope. The bigger cost driver is the work itself.

• Panel upgrades from 100-amp to 200-amp typically run in the low thousands, depending on service size, where the meter sits, and how much coordination is needed with the utility to disconnect and reconnect power

• Generator inlets, interlocks, and transfer switches run from several hundred dollars for a basic interlock kit to a couple thousand for a full transfer switch setup with sub-panel

• Distance from the panel to where new circuits need to go adds cost, especially if wire has to run through finished walls versus open framing

• Permit and inspection fees add a smaller but real cost on top, usually built into your electrician's quote

Open stud walls keep labor down because wire runs are straightforward. Finished walls mean cutting, fishing wire, and patching, which adds hours. If you're planning a remodel anyway, doing panel or circuit work before drywall goes up saves money.

Signs you're due for a panel upgrade

A few patterns show up again and again in older North Idaho homes and cabins:

• Breakers trip frequently, especially when running multiple appliances at once

• Lights flicker or dim when the AC or well pump kicks on

• The panel is rated 100-amp and the house has since added a heat pump, EV charger, or hot tub

• The panel still uses fuses instead of breakers

Any of these mean it's worth having someone look at the panel before adding more load to it. Waiting until something fails usually costs more than upgrading ahead of time.

Working with someone who pulls permits as a matter of course

Ask any electrician bidding your job whether the quote includes the permit and inspection. If it doesn't, ask why. A contractor who skips permits to save you money up front is passing the risk to you later.
