What an Electrical Inspection Reveals When Buying an Older Idaho Home

You found an older home in Sagle, Sandpoint, or Coeur d'Alene with good bones and a price that seems fair for the market. Then the inspection report comes back with a page of electrical findings you don't fully understand, and the closing clock is ticking. Here is what those findings usually mean and how to use them at the negotiating table.

Older homes in Bonner and Kootenai counties were often wired in the 1950s through 1980s, sometimes earlier, and updated in pieces over the decades by different owners and contractors of varying skill. An inspection on a home like this almost always turns up something. The question is whether it is a minor note or a real safety and budget issue.

Most likely cause

The single most common finding is an outdated or undersized electrical panel. Many older Idaho homes still have 60 or 100 amp service, sometimes with fuses instead of breakers, and brands like Federal Pacific or Zinsco that are known for failing to trip properly under fault conditions. A modern household with electric heat, a heat pump, a well pump, a shop, or an EV charger needs more capacity than these panels were built to deliver.

You confirm this by looking at the panel label and asking the inspector or an electrician to identify the brand and amperage. If it says Federal Pacific Electric or Zinsco, treat that as a real finding, not a cosmetic one. Insurance companies in North Idaho are increasingly declining to write policies on homes with these panels, or they require replacement first. That alone can affect your financing timeline.

Less common causes

Knob and tube wiring shows up in homes built before about 1950, mostly in Sandpoint's older neighborhoods and farmhouses scattered through the valley. It is not automatically dangerous if untouched and not insulated over, but most insurers won't cover a home that still has active knob and tube circuits. Confirm by having the inspector check the attic and basement for the ceramic tube fittings and cloth-covered wire, and ask whether it's still live or has been abandoned in place.

Aluminum branch wiring is another one, common in homes built roughly 1965 to 1975 when copper prices spiked. Aluminum wire expands and contracts more than copper and can work loose at outlets and switches over time, leading to overheating at the connection points, not usually the wire itself. Confirm by checking wire jacket markings at an outlet or panel, they will read AL or aluminum. This isn't always a full rewire situation, sometimes it is remediated with proper connectors (often called pigtailing with anti-oxidant compound) at each device, which is far cheaper than a whole-house rewire.

Ungrounded outlets are common in homes with older wiring that never got updated, especially two-prong outlets throughout the house. An inspector tests this with a simple plug-in tester. It's a real issue for sensitive electronics and for anything with a three-prong plug, but it is also one of the more affordable things to address, since grounding can sometimes be added without pulling new wire through every wall, depending on the setup.

How to fix it

Once you have the inspection report, the practical path looks like this:

• Get a licensed electrician to walk the house separately from the general inspector. General inspectors flag electrical issues but usually aren't licensed electricians, and their report is a starting point, not a scope of work.
• Ask for a written estimate on each major item: panel replacement, any knob and tube removal, aluminum wiring remediation, and grounding. Get ranges, not guesses. A panel upgrade alone commonly runs several thousand dollars depending on size and utility connection work; a full rewire of an older home can run well into five figures depending on square footage and access.
• Decide what you'll ask the seller to fix, credit, or reduce price for. Safety items like a Federal Pacific panel or active knob and tube are reasonable things to negotiate hard on, since they affect insurability, not just preference.
• Get an insurance quote before closing if the home has any of these issues. Some insurers will quote conditionally on repairs being completed within a set window after closing, others won't quote at all until it's done.
• If you're keeping the home, schedule the highest-priority items first: panel and grounding for safety and insurance, then aluminum wiring remediation, then cosmetic or convenience upgrades like additional outlets or circuits for a shop or garage.

When it is not worth fixing

Not every finding needs to become a deal point. A few extra ungrounded outlets in a low-use room, a panel that is merely old but not on a recalled list, or minor code differences from decades of updates are normal in a home this age and rarely worth killing a sale over. Almost no home built before the 1990s will pass a modern code inspection outright, and that's expected, not alarming.

Where it does become worth walking away, or at minimum insisting on serious credits, is when the electrical problems are tangled into the rest of the house. If knob and tube wiring runs through insulated walls and ceilings where it shouldn't be, if a home has had unpermitted additions with electrical work you can't verify, or if the seller can't produce any history of updates on a house that clearly needs them, the electrical findings are often a signal about the overall maintenance of the property, not an isolated repair.

Cabin and second-home buyers in Bonner County should pay particular attention here. Cabins that sat unoccupied for stretches, or were wired for occasional weekend use decades ago, often have electrical systems that were adequate for a simple cabin but are not remotely sized for what buyers want now, like heat pumps, hot tubs, or a home office. The inspection cost to figure this out up front is small compared to discovering it after you've moved in and started adding loads to an old system.

Builders and small business buyers looking at older commercial buildings in Sagle, Ponderay, or Coeur d'Alene should expect the same categories of issues, just at a larger scale, and should budget for a licensed electrical review before finalizing any purchase, since commercial panel and service upgrades cost more and take longer to schedule with the utility.

In every case, the electrical inspection isn't there to scare you off an older home. It's there to give you real numbers so you can negotiate from facts instead of guesses. If you're buying in Bonner or Kootenai county and want a second opinion on what an inspection report actually means for your budget, Sageland Electric can walk the property with you before you finalize an offer.
