When Should Electrical Planning Start for a Sarasota Custom Home or Build-Out? | CoHarbor Electric

We get asked this one a lot, usually by homeowners who are already a few months into the process and starting to wonder if they’re behind. Short answer: earlier than most people think. Longer answer is worth walking through, because “early” means something different depending on which stage of a luxury build you’re actually in — and getting the timing wrong at any one of those stages tends to cost real money later.

We’ve worked custom home projects from the ground up around Bird Key, Sapphire Shores, The Oaks, and out toward Lakewood Ranch Country Club, and the pattern is almost always the same. The projects that go smoothly are the ones where the electrical contractor got a seat at the table early. The ones that run into snags — change orders, ceiling heights that don’t accommodate the fixtures the homeowner wanted, a panel that needs to be relocated after drywall — are almost always the ones where electrical didn’t enter the conversation until construction was already underway.

Before the Architect Finishes Drawings

This is the stage most homeowners skip entirely, and it’s the one that would save the most headaches if they didn’t.

If you’re building a luxury custom home, you almost certainly have plans for things that go well beyond a standard electrical package — a whole-home automation system, a wine room with climate control, a home theater, an outdoor kitchen and pool complex, maybe a car collection that needs EV charging and specialty lighting in the garage. Every one of those decisions affects the load calculation, the panel size, and where equipment physically needs to live in the house.

We’d rather have that conversation while the architect is still drawing floor plans than after they’re finalized. Once drawings are locked, moving a panel location or adding square footage for an equipment room means redlines, delays, and usually a fee from the architect for the changes. We’ve sat in on early design meetings for homes near Casey Key and Sanderling where a fifteen-minute conversation about equipment room placement saved the homeowner a wall relocation three months later.

During Permitting

By the time permit drawings go to Sarasota County, the electrical scope needs to be locked in — or close to it. This is where load calculations get finalized, panel size gets specified on the drawings, and the utility coordination with FPL for the service entrance and meter location gets sorted out.

If big decisions are still up in the air at this point — say, the homeowner hasn’t decided on generator size, or the smart home scope keeps changing — permit review tends to drag. Plan reviewers kick back applications that don’t match what’s actually going to be built, and every revision cycle adds weeks to a timeline that’s usually already tight. We always tell clients: if you’re still deciding on major electrical features once permit drawings are submitted, you’re deciding later than you should be.

During Framing — Last Reasonable Point Before Rough-In

Framing is really the last comfortable window to finalize anything before rough-in wiring begins. Once framing is complete and rough-in starts, changes get expensive fast, because now you’re talking about moving wire that’s already run through studs and joists, not just adjusting a drawing.

This is the stage where we walk the house in person with the homeowner — every switch location, every outlet, every ceiling fixture, every spot where a future chandelier or statement lighting piece is going to hang. It sounds tedious, but it’s a lot cheaper to move a switch six inches during a walkthrough than to open a finished wall for it later. We did exactly this on a build near Indian Beach a while back, where the homeowner’s lighting designer hadn’t finalized fixture locations until framing was nearly done — we caught two ceiling boxes that needed relocating before rough-in started, which took twenty minutes instead of becoming a drywall repair.

What Happens When Planning Starts Too Late

Worth being honest about this part. When electrical planning doesn’t start until rough-in or later, a few things tend to happen:

• Panel upgrades get squeezed in reactively instead of planned around the home’s actual long-term load
• Low-voltage and smart home wiring gets bolted on after the fact, meaning conduit gets fished through finished framing instead of run cleanly during rough-in
• Change orders pile up, and each one usually costs more than it would have during the design phase
• Inspection delays happen when drawings and field conditions don’t match

None of this is catastrophic — we fix these situations all the time — but it’s slower and more expensive than it needed to be. If you’ve read our guide on what’s included in Sarasota new construction electrical work, you already know how many pieces need to be coordinated. Starting that coordination late just means doing the same work under worse conditions.

Build-Outs and Later Additions

Even after move-in, a lot of luxury homeowners come back to us wanting to add something — a generator they held off on, an EV charger, a home theater upgrade, expanded outdoor lighting. That’s normal, and none of it means the original planning failed. But the same principle applies at a smaller scale: the earlier you loop us in on an addition, the more options you have, and the less likely you are to be working around finished walls and landscaping that’s already established. We’ve covered generator and backup power planning in more detail in our hurricane season panel planning guide, which is worth a look if that’s part of what you’re weighing.

Talk to Us Before You Talk to Your Builder

If there’s one thing worth taking away from this, it’s that electrical planning works best as an early conversation, not a checklist item during construction. Coharbor Electric is licensed and insured, and we sit in on design meetings for custom home clients across Sarasota, Bird Key, Siesta Key, Casey Key, Sanderling, and Lakewood Ranch specifically because the earlier input tends to save homeowners money and headaches down the line.

If you’re in the early planning stages of a luxury custom home or thinking through a build-out addition, reach out to us before drawings are finalized. That’s the point where our input does the most good.
