Electrical Upgrades Older Sarasota Homes Need Before Renovation | CoHarbor Electric

We got called out to a bungalow off Laurel Park a few months back — gorgeous old place, original pine floors, the kind of character you can’t buy new. The homeowners were three weeks from breaking ground on a kitchen remodel. New cabinets ordered. Backsplash picked out. And then someone finally asked us to take a look at the panel before the contractor started tearing into walls. Good thing they did. That panel was a 60-amp original, feeding a home that was about to get a double oven, an induction cooktop, and under-cabinet lighting. It wasn’t close to enough. Not even close.

That’s the story more often than not. Renovation plans get built around cabinetry and countertops, and the electrical system gets treated like an afterthought — something that’ll “probably be fine.” In an older Sarasota home, that assumption costs people money, and sometimes it costs them their timeline entirely.

Why Renovation Is the Moment That Exposes Everything

Here’s the thing about old wiring — it doesn’t announce itself. Lights turn on, outlets work, nobody’s had a fire. So it’s easy to assume the system’s fine. But “fine” and “adequate for a 2026 renovation” are two very different standards. A renovation is exactly the moment when hidden problems get pulled into the light, because you’re opening walls, adding load, and — if you’re pulling a permit, which in Sarasota County you will be for anything involving new circuits or a panel change — you’re inviting an inspector to look closely at what’s actually there.

We’d rather find the surprises before demo day than during it.

The Panel Is Usually the First Bottleneck

A lot of homes built before the late 1980s in neighborhoods like McClellan Park, Southside Village, and Indian Beach/Sapphire Shores were built with panels sized for a much simpler electrical life — a window unit here, a few lamps, maybe a window AC and a washer. Nobody was planning for a tankless water heater, a home office with three monitors, and an EV charger in the garage.

When we assess an older home ahead of a renovation, panel capacity is one of the first things we check. If you’re adding a kitchen island with dedicated small-appliance circuits, a laundry upgrade, or any real load increase, and the existing panel is sitting at 100 amps or less with limited breaker slots, that panel is going to be a constraint on your whole project — not just an electrical detail.

Aluminum Wiring — An Older Sarasota Wildcard

If your home was built roughly between 1965 and 1973, there’s a real chance some of the branch circuit wiring is aluminum instead of copper. It’s not automatically dangerous, but aluminum connections loosen over time in a way copper doesn’t, and that creates heat at the connection point — which is where problems start. We don’t panic when we find it. We just want to know it’s there before a renovation buries it further behind new drywall. Sometimes the fix is targeted — pigtailing connections with the right connectors — and sometimes, depending on scope, a broader plan makes more sense.

Grounding, GFCI, and the Code Questions That Come Up

A common surprise for homeowners: ungrounded outlets. Older homes often have two-prong outlets, or someone’s swapped in three-prong outlets over the years without actually running a ground wire back to the panel. It looks fixed. It isn’t. Under the National Electrical Code, kitchens, bathrooms, and outdoor spaces need GFCI protection, and a lot of newer requirements call for AFCI protection too, particularly on circuits serving bedrooms and living spaces. NEC Article 210 covers a good chunk of these branch circuit requirements, and if your renovation touches those spaces, bringing them up to current code isn’t optional — it’s part of pulling the permit.

We see this trip people up in Whitfield Estates and Sarasota Springs pretty regularly — homeowners who assumed their kitchen outlets were already GFCI-protected because there’s a test button on one of them, when really only that one outlet has protection and the rest of the circuit doesn’t.

The Load Calculation Nobody Thinks About

Every renovation that adds meaningful electrical load — a new HVAC system, an EV charger, a pool heater, an expanded kitchen — should trigger a load calculation under NEC Article 220. This is the math that determines whether your existing service size can actually handle everything you’re planning to plug into it. Skip this step, and you might finish a beautiful renovation only to find breakers tripping constantly because the service was never sized for the finished product.

This is also where FPL comes into the conversation. If a load calculation shows you need a larger service — moving from 100 amps to 200, for example — that’s coordination with FPL on the utility side, not just something we handle in-house. Better to know that early, while it can still be scheduled around your renovation timeline, than to discover it after the drywall’s up.

Common Mistakes We See Homeowners Make

Assuming “it’s working” means “it’s adequate.” Working and up-to-code aren’t the same thing. A lot of what’s original to a 1970s Sarasota home worked fine for decades — right up until it’s asked to do more than it was built for.

Not budgeting for electrical in the renovation number. We understand nobody wants a line item for panel work eating into the tile budget. But finding out mid-project that the panel needs replacing is far more disruptive — and often more expensive — than planning for it up front.

Skipping the assessment because “the last owner just remodeled the bathroom.” A bathroom remodel five years ago doesn’t tell us anything about the panel, the service size, or the wiring in the rest of the house. Every renovation should start with its own look at what’s actually there.

Assuming permits are just paperwork. In Sarasota County, permits for electrical work tied to a renovation exist so an inspector can verify the work meets current code — grounding, GFCI/AFCI protection, proper panel labeling, and so on. Skipping that step, or having a contractor who isn’t pulling permits correctly, can turn into a real problem when you go to sell the house later.

What a Pre-Renovation Electrical Assessment Actually Looks Like

When we walk a home before a renovation starts, we’re checking panel age and capacity, wiring type and condition, grounding throughout the areas being touched, and whether the planned scope — new appliances, added circuits, expanded square footage — will push the existing system past what it can reasonably handle. We’ll give you a straight answer on what needs to happen, what can wait, and roughly where that fits into your renovation timeline and budget. No scare tactics, no upselling work that isn’t needed. Just an honest read on the house you actually have.

Let’s Look Before the Demo Starts

If you’re planning a renovation on an older home anywhere in Sarasota — Laurel Park, McClellan Park, Southside Village, Indian Beach/Sapphire Shores, Whitfield Estates, or elsewhere in the area — it’s worth having us walk the space before your design is finalized. Coharbor Electric is a licensed and insured electrical contractor serving Sarasota County, and we handle everything from panel assessments and permit-pulled upgrades to full rewires when that’s what the house actually needs. Reach out to Coharbor Electric to schedule a pre-renovation electrical assessment, and let’s make sure your wiring can keep up with the rest of the project.
