What an Electrical Inspection Can't Tell You When Buying a Naples Home | CoHarbor Electric

Had a buyer call us a couple years back, already a week past closing on a place near Coquina Sands. Her home inspection report had come back clean — “electrical: satisfactory,” one line, no flags. Then her first power bill showed up almost double what the sellers had quoted her, and a breaker in the garage kept tripping every time she ran the washer and the AC at the same time. Nothing on that report told her any of that was coming. And that’s not the inspector’s fault, really — it’s just not what a general home inspection is built to catch.

If you’re buying in Naples right now, it’s worth understanding what that standard inspection actually covers electrically, and more importantly, what it doesn’t. Because “satisfactory” on a report and “actually fine” are not always the same thing.

What a General Home Inspector Is Actually Checking

A licensed home inspector in Florida is trained broadly — roof, structure, plumbing, HVAC, electrical, and more, all in one visit that usually runs a few hours. On the electrical side, that typically means a visual check of the panel, confirming outlets are wired correctly with a simple tester, checking GFCI protection in bathrooms and kitchens, and looking for obviously exposed or damaged wiring. It’s a real inspection, and it catches real problems. But it’s a visual pass, not a diagnostic one, and it’s one part of a much longer checklist covering the entire house.

Load Capacity Is Almost Never Actually Calculated

Here’s the biggest gap we see constantly. A home inspector will note the panel’s amperage rating — say, 100 amp or 150 amp — but they’re not typically running an actual load calculation against everything the house draws. That’s a different exercise, one governed by NEC Article 220, and it tells you whether the existing service can actually support what you’re running, or what you’re planning to add later. A pool home in Naples with a spa heater, a couple of AC units, a pool pump, and a growing number of smart appliances can be a lot closer to its ceiling than the panel size alone suggests. We’ve opened panels in homes with inspection reports calling the electrical “satisfactory” and found almost no headroom left for anything new — a hot tub, an EV charger, a home office buildout.

Double-Tapped Breakers and Panel Brand Issues

A general inspector might catch an obviously overcrowded panel, but subtler problems slip through more than people expect. Double-tapped breakers — two circuits landed on a single breaker slot not rated for it — are a common one, and they’re not always visually obvious unless you’re specifically looking for it and know what you’re looking at. Certain older panel brands, like Federal Pacific or Zinsco, carry known failure risks that a general inspector might mention in passing but won’t necessarily flag as urgent, because “this panel brand has documented issues” requires trade-specific knowledge, not just a visual pass.

Permit History Doesn’t Show Up on a Home Inspection at All

This one surprises almost every buyer we talk to. A home inspection tells you what the house looks like right now. It says nothing about whether the electrical work behind the walls was actually permitted through Collier County when it was done. We’ve walked into homes near Aqualane Shores and Victoria Park where a previous owner clearly did their own panel swap or added circuits without ever pulling a permit — work that can look perfectly fine to the eye and still be unpermitted, uninspected, and technically out of code. That’s not something a standard inspection report is designed to surface, and it’s something you’d only find by pulling county permit records or having an electrician physically trace the work.

Checking Collier County’s permit history on a property takes maybe fifteen minutes and it’s public record — most buyers just don’t know to ask for it, or don’t know it exists as a separate step from the home inspection itself. It’s not a guarantee everything’s fine if permits are there, and it’s not automatically a disaster if they’re missing, but it’s a data point worth having before you’re the one holding the house.

Coastal Corrosion Doesn’t Always Show on the Surface

Naples’ salt air and humidity get into places a quick visual inspection won’t reach — inside outdoor disconnect boxes, at exterior outlet covers, around pool equipment pads. We’ve found corroded terminals inside boxes that looked completely fine from the outside, the kind of thing that only shows up once someone actually opens the panel or disconnect and looks at the connections directly. A general home inspector isn’t necessarily opening every exterior electrical box on the property during a standard walkthrough.

The Difference Between “Passes” and “Will Last”

A general inspection is really answering one question: is anything obviously wrong right now. It’s not answering: how much life is left in this wiring, is this panel going to need replacing in five years, or is this system actually sized for how the next owner is going to live in the house. Those are different questions, and they matter more for a purchase decision than a pass/fail line item might suggest.

Aging Wiring Doesn’t Announce Itself on a Visual Pass

A general inspector is checking whether outlets test correctly and whether wiring is visibly damaged — reasonable things to check, but they don’t tell the full story of a wiring system’s actual condition. Aluminum branch wiring, common in some Naples homes built in the 60s and 70s, can test fine electrically while still carrying a known long-term risk at the connection points, where it tends to loosen and overheat over time in a way that isn’t visible without opening the box and looking. Insulation on old wiring degrades from heat exposure in attic spaces too, especially in a climate like ours where attic temperatures regularly climb well past what the wiring’s original insulation was rated to handle indefinitely. None of that shows up as a failed outlet test. It shows up years later, usually at an inconvenient time.

The Insurance Angle Nobody Mentions During the Home Inspection

Here’s something that catches a lot of new Naples buyers off guard a few months after closing. Insurance companies increasingly want their own 4-point inspection before writing or renewing a policy on an older home, and that inspection asks different questions than your purchase inspection did — specifically about panel age, wiring type, and whether the system’s been updated. We’ve had calls from homeowners whose purchase inspection came back clean, only to have an insurance carrier flag the same panel a few months later and require upgrades before they’ll renew coverage. Knowing that ahead of time, during your option period rather than after closing, means you can factor it into your offer instead of getting hit with an unplanned expense your first year in the house.

What We’d Actually Recommend During Your Option Period

If you’re under contract on a home anywhere in Naples — whether it’s an older place near East Naples or a newer build out toward Golden Gate Estates — it’s worth having a licensed electrician do a separate, focused electrical assessment during your inspection period, especially if the home is more than fifteen or twenty years old. That typically means opening the panel, doing an actual load calculation, checking permit history through the county, and physically inspecting exterior equipment for corrosion. It’s a different level of detail than what the general inspection covers, and it gives you real numbers to negotiate with before you close, not surprises after.

Questions Worth Asking Before You Close

• Has the panel or any circuits been added or upgraded, and is there permit history to back it up?
• What’s the actual panel brand, and does it have any known reliability issues?
• Is there real headroom on the panel for future additions, or is it already near capacity?
• Has anyone actually opened exterior electrical equipment recently, or just looked at it from outside?

If Something Does Turn Up, You Still Have Options

Finding a real issue during this deeper look doesn’t necessarily mean walking away from the house. Most of the time it means going back to the negotiating table with actual numbers — a documented load calculation showing the panel’s near capacity, a written estimate for bringing unpermitted work up to code, a real quote for replacing a known-risk panel brand. Sellers are often more willing to negotiate a credit or a price adjustment when they’re looking at a specific number from a licensed contractor than a vague concern from a buyer. We’ve sat in on more than one of these conversations, and having something concrete in hand tends to move things along faster than a general sense that “the electrical seemed off.”

Get a Second, Deeper Look Before You Close on a Naples Home

A clean home inspection report is a good sign, but it’s not the whole picture on the electrical side. Coharbor Electric is licensed and insured, and we work with Naples buyers during their option period to give the electrical system a real, hands-on look — panel condition, load capacity, permit history, and anything a general inspection wouldn’t have caught. Reach out to Coharbor Electric before you close, and let’s make sure the house you’re buying is as sound electrically as the report says it is.
