When Sarasota Homes Need a 200-Amp Panel for EVs, Pools, or Additions | CoHarbor Electric

We get this question pretty regularly — usually from someone who just bought an EV, or who’s getting quotes on a pool, or who’s finally pulling the trigger on that addition they’ve been planning for three years. The question is some version of: “Do I need to upgrade my electrical panel for this?”

And the answer is: maybe. But in a lot of Sarasota homes, especially anything built before the mid-’90s, the answer leans toward yes — and it’s worth understanding why before you’re three weeks into a project and an electrician is telling you there’s no room left in the panel.

Most Older Sarasota Homes Were Built for a Different Life

When a house goes up, the electrical service gets sized for what the builder expects people to put in it. In the ’70s and ’80s, that meant lights, a few outlets, maybe an electric range, a central AC unit, and a washer and dryer. That’s a 100-amp life. Some older homes around Gulf Gate Estates, Southgate, and the neighborhoods north of downtown that got built out in that era — 100-amp service was completely standard. A few were wired for even less.

Then life changed. People started running two refrigerators. Home offices became a thing. Outdoor kitchens went in. Big flat-screen TVs in every room, game consoles, streaming devices. All of it adds up. A house that was fine on 100 amps in 1983 has been slowly accumulating load for forty years.

Then someone decides to add a pool, or buys a Tesla, or wants to put a mother-in-law suite over the garage. And now we’re having the panel conversation.

Even homes that are newer — built in the ’90s or early 2000s — were frequently wired for 150-amp service. That was a step up from the older stock, but it’s not necessarily enough for the way people use electricity today, especially once you start adding large dedicated loads.

What a 200-Amp Panel Actually Gets You

Before getting into the specific scenarios, it helps to understand what you’re actually getting when you upgrade to 200-amp service.

The service size — 100 amps, 150 amps, 200 amps — is the maximum amount of electrical current your home can draw at any given time. Think of it like the size of the pipe bringing water into your house. A bigger pipe doesn’t mean you’re using more water constantly — it means you can run more things at once without pressure dropping. Same idea here.

A 200-amp panel also typically comes with more circuit spaces. An older 100-amp panel might have 20 or 24 spaces, and in a home that’s had work done over the years, those spaces fill up fast. A 200-amp panel usually offers 40 or more spaces — room to add the circuits you need without doubling up or adding a sub-panel as a workaround.

And in terms of future-proofing: if you’re going to put money into your home’s electrical system, doing it once and doing it right beats a piecemeal approach that has you calling an electrician back every two years.

Electric Vehicles

The Real Story on EV Charging

This is probably the most common conversation we’re having right now. EV ownership in Southwest Florida has grown a lot in the last few years, and there’s a persistent myth that you can just plug your car into a regular outlet and call it fine. You can — technically. A standard 120-volt outlet will charge an EV. It’ll just add about four or five miles of range per hour, which means if you drive a normal amount and you’re starting from a depleted battery, you’re looking at two or three days to fully charge.

Most EV owners eventually want a Level 2 charger — a 240-volt dedicated circuit that can add 25 to 30 miles of range per hour. That’s a meaningful difference. You plug in when you get home, wake up in the morning, car’s charged. That’s how it’s supposed to work.

A Level 2 charger needs a dedicated 240-volt, 50-amp circuit. That’s not something you pull from the existing wiring. That’s a new circuit run from the panel, and it requires a 50-amp breaker space to put it in.

When the Panel Becomes the Bottleneck

Here’s where we run into issues. We get called to do an EV charger install and the homeowner has a 100-amp panel that’s already got 18 or 20 circuits on it. There’s one breaker space left, maybe two. You can’t put a 50-amp circuit in a panel that doesn’t have the capacity to support it.

Even if there are physical spaces available, a 100-amp panel can’t always handle the additional load a 50-amp EV circuit represents — especially if the house is already running AC, an electric water heater, a dryer, and everything else at once. The math has to work out, not just the space.

In those cases, we have the panel conversation. And for a lot of Sarasota homeowners with older service, a panel upgrade is the right move anyway — the EV charger just became the tipping point.

Swimming Pools

Why Pools Are a Big Electrical Load

Sarasota has a lot of pools. The climate makes them practical nine or ten months of the year, and in neighborhoods like Palmer Ranch, Lakewood Ranch, and the waterfront areas around the bay, a pool is almost expected. But pools are also one of the larger electrical loads you can add to a residential property.

A typical residential pool setup includes a pump motor — often 1.5 to 2 horsepower, sometimes more — plus pool lighting, a heater or heat pump if you have one, an automated controller, and often a spa with its own jet pump. A basic pool pump alone typically needs a 20-amp dedicated circuit. A pool heat pump can pull 30 to 50 amps on its own. Add the lights, the automation, the spa equipment, and you’re looking at two, three, sometimes four dedicated circuits just for the pool system.

Every one of those needs its own breaker space and its own conductor run back to the panel. In a panel that’s already full or close to it, that’s a problem.

Code Compliance Adds Circuits Too

Pools in Florida also require specific wiring under NEC Article 680 — the code section that governs swimming pools, spas, and fountains. There are rules about GFCI protection, bonding, and the placement of receptacles near water. None of that is optional, and it all adds to the circuit count. When we do a pool electrical installation, we’re always doing it to code, which means accounting for all of it — and that means confirming the panel has the capacity before we start pulling wire.

If your panel is a 100-amp unit with limited space and you’re adding a full pool and spa setup, a 200-amp upgrade isn’t a luxury. It’s just what the project requires.

Home Additions and ADUs

Adding Space Means Adding Load

An addition — whether it’s a guest suite, a converted garage, an in-law apartment, or an extra bedroom — adds habitable space and the electrical load that goes with it. New square footage means new lighting circuits, new outlet circuits, sometimes a dedicated circuit for a mini-split AC unit, potentially a kitchenette circuit if it’s a full suite.

A modest addition of 300 to 400 square feet can easily require four to six new circuits. Larger additions or full ADUs might need eight, ten, or more. If the existing panel doesn’t have the physical space or the amperage capacity to absorb that, the addition becomes the trigger for an upgrade.

The Permit Process Makes This Visible

When you pull a permit for an addition in Sarasota County, the electrical portion of the inspection process looks at whether the existing service is adequate for the new total load. If the inspector or the electrical plan reviewer determines that the service is undersized for what’s being added, you’re upgrading the panel before the addition gets signed off. There’s no way around it.

We’ve seen homeowners get surprised by this mid-project. The framing is up, the drywall is going in, and they find out they need a panel upgrade they hadn’t budgeted for. Getting an electrician involved at the planning stage — before the permit application, ideally before the contractor bids are even final — avoids that scenario.

Outdoor Kitchens and Whole-Home Generators

Outdoor Living in Sarasota Means Real Electrical Load

Outdoor living spaces are a big part of how people use their Sarasota homes. A covered lanai with a fully equipped outdoor kitchen — refrigerator, ice maker, outlets for appliances, lighting, ceiling fans, maybe a TV — can need three or four dedicated circuits on its own. Not a problem if the panel has room. A real conversation if it doesn’t.

Generator Connections

Whole-home generators have become a much more common discussion after the hurricane seasons of the last several years. A standby generator needs a transfer switch and its own connection to the panel — or in the case of a whole-home system, a service-side connection that requires adequate panel capacity to be useful in the first place. You can’t install a 22-kilowatt generator on a 100-amp panel and expect it to power much of anything meaningful.

If you’re thinking about a whole-home generator, the panel conversation is part of that conversation whether you want it to be or not.

What the Upgrade Process Looks Like

A service upgrade in Sarasota — going from 100 or 150 amps to 200 amps — involves a few moving parts. First, we pull a permit with Sarasota County. Then we coordinate with FPL, who needs to come out to pull the meter before we do the panel work. We install the new panel and make all the connections. FPL comes back to restore power after our work is done. Then we schedule the county inspection.

The electrical work itself is usually a day, sometimes a day and a half for a more complex service entrance upgrade. Most homeowners are without power for a few hours during the swap. It’s not a multi-day ordeal.

The permit and inspection process exists for good reason. Anyone telling you they can do a service upgrade without a permit is telling you they’re doing work that won’t be inspected — and in Florida, uninspected electrical work can create real problems when you sell the home or file an insurance claim.

Not Every Home Needs 200 Amps — But Many Do

We’re not in the business of upselling people on things they don’t need. If a homeowner has a newer home with 200-amp service already installed and they want to add an EV charger, we look at the available capacity and existing load and figure out if it works. Often it does.

But for a significant portion of the existing housing stock in Sarasota — particularly the homes built in the ’70s, ’80s, and early ’90s that make up so much of Gulf Gate, Southgate, the areas around South Trail, and the older sections of Venice and Nokomis — 100-amp service is a starting constraint, not a permanent limitation. The electrical system in the house should serve the life you’re actually living, not the life someone imagined in 1982.
