New Construction Electrical Wiring for Custom Homes

Full permitted, inspected wiring by a licensed master electrician — across the Galveston Bay & South Houston corridor.

You're building a house from the ground up. The electrical isn't a fixture swap or a breaker replacement — it's the whole nervous system of the home, wired once, inside the walls, and inspected before anyone closes them up. You want the electrician who pulls the permit, wires it to NEC 2023, and schedules the inspection themselves — not a sub who's here today and gone before the final.

That's the job TriCoast does: complete new-construction wiring, rough-in through final inspection, by a licensed master electrician.

We're not always the cheapest bid on your build. We pull the permit, wire to NEC 2023, and schedule the inspection ourselves — and we stand behind the work with a workmanship warranty. If you're collecting bids, weigh that against the sub who hands you the permit paperwork and asks you to file it.

Who it's for

Who this page is for

You're in the right place if you're:

  • An owner-builder putting up a custom home and sourcing your own electrical contractor.
  • A homeowner acting as your own GC who needs a licensed sub to handle the full electrical scope — and the permit and inspections that come with it.
  • A builder or GC looking for a residential electrical sub who shows up, wires it to code, and passes inspection the first time.

All three need the same thing: a master electrician who can take a set of plans and wire a whole house, permitted and inspected, without surprises.

Building an addition or doing a gut remodel instead of a ground-up house?

That's a different job — see Remodel & Addition Wiring.

Full scope

What full new-construction wiring covers

New-construction wiring is a multi-phase job, and getting it right means doing each phase in the right order. Here's the actual sequence we work through on a custom home — so you can see exactly what you're hiring for.

Load calculation & service sizing

Before we run a single wire, we calculate the home's actual electrical load and size the service to match it — typically a 200-amp service, but sized to your plans, not a guess. Bigger isn't automatically better and undersized isn't an option. We calculate; we don't eyeball it. (See the FAQ on load calcs below.)

Service entrance & panel

The meter, service entrance, main panel, grounding, and bonding — set and wired to code. This is the backbone of the whole system. (For the service/panel specifics on an existing home, see Panel Upgrades.)

Rough-in

With the framing open, we run all the circuits: branch circuits, dedicated appliance and EV-ready circuits, HVAC, kitchen and bath, exterior, and structured/low-voltage pre-wire where your plans call for it. This is the phase that's nearly impossible to fix cleanly once the drywall is up — so it's the phase that rewards a careful, code-literate electrician.

Code & safety devices

GFCI and AFCI protection, whole-home surge protection, smoke/CO, and proper grounding — all per NEC 2023.

Trim-out

Once the walls are closed and finishes are in, we install devices and fixtures and label the panel clearly. A labeled panel is a small thing that pays off every time someone troubleshoots the house for the next 30 years.

Permit & inspection

We pull the electrical permit, and we schedule the rough-in and final inspections. More on why that matters below.

Placeholder — needs real data:

2–4 real rough-in / trim-out / panel job photos with one-line captions; confirmation of new-build projects completed in the corridor. Until confirmed, claims stay capability-framed ("we handle full new-construction wiring"), NOT volume-framed ("we've wired X homes").

Want to plan ahead? We can rough-in for an EV charger, a generator circuit, or smart-home wiring now, while the walls are open, so it's ready when you are.

Permits & inspection

Permitting & inspection on a new build

On a from-scratch house, the permit isn't paperwork — it's the difference between a home you can insure and sell, and one with a problem buried in the walls.

In Houston, electrical permits are issued only to a registered master electrician. A homeowner can't pull it. A handyman can't pull it. We can — and we do. If a sub asks you to file the permit, that's a signal worth paying attention to.

Here's what's actually at stake when electrical work on a new build goes unpermitted or uninspected:

  • A failed inspection stalls your whole schedule. On a build with a closing date and a construction loan, a re-inspection is days or weeks you don't get back.
  • Unpermitted work can stall a sale. When you sell, the permit history travels with the house. A buyer's inspector flagging unpermitted electrical can kill or delay the deal.
  • Insurance can deny a claim tied to work that was done without the required permits and inspections.

We pull the permit, coordinate the rough-in and final inspections, and the permit stays with the house — a real asset at resale, not a liability hiding behind the drywall.

Coastal credential

Building in Galveston jurisdiction? WPI-8 / TWIA windstorm certification

If your new build sits in Galveston jurisdiction, there's a coastal credential most corridor electricians never surface — and it's the one that decides whether you can insure the house.

WPI-8 is the Texas Department of Insurance windstorm certification required on coastal new construction (and solar and major-exterior work). Here's why it's non-negotiable: no WPI-8 compliance → no TWIA policy → you can't get windstorm insurance on the home. The Texas Windstorm Insurance Association won't write the coverage without it.

TriCoast handles the electrical scope of a Galveston-jurisdiction build with that windstorm-certification compliance in mind from the start — so the electrical isn't the thing that holds up your WPI-8 sign-off.

To be clear about scope: this applies to Galveston-jurisdiction builds, not the whole corridor. If you're building on the mainland, it likely doesn't apply to you.

The trust stack

Why TriCoast for your build

A new build is a months-long, multi-phase relationship — not a one-hour service call. Here's the trust stack you're signing up for:

  • A licensed master electrician — TDLR EC #EECELE00037785, 27+ years of experience. Real credentials, not "expert" puffery.
  • Permits and inspections handled — pulled and scheduled by us.
  • NEC 2023 code-compliant, with a workmanship warranty behind the job.
  • No-upsell, straight pricing — quoted off your actual plans, no surprise bills.
  • Local and accountable — we're in the Galveston Bay corridor, and we answer the call when you need a callback. Not an out-of-area generalist who's hard to reach by trim-out.

Both techs were very knowledgeable and professional from start to finish. They left the job site clean and all work was tested and reviewed with us before they left. My wife and I were extremely impressed. I would recommend TriCoast to all my friends and family.

FAQ

Frequently asked questions

Do you pull the electrical permit for a new home build?

Yes. In Houston, electrical permits are issued only to a registered master electrician — a homeowner legally can't pull one. We're that master electrician, so we pull the permit and schedule the rough-in and final inspections. And the permit stays with the house: when you sell, that clean, inspected permit history is an asset rather than a problem buried in the walls. (More on Texas permits.)

Do you run a load calculation before sizing the service and panel?

Always. We calculate the home's actual electrical load from your plans and size the service to match it — often a 200-amp service, but sized to your home, not a default. We'd rather verify the right service size than over-spec you into a bigger bill or under-spec you into a problem. We calculate; we don't guess.

My new home is on Galveston Island — do I need WPI-8 windstorm certification?

If your build is in Galveston jurisdiction, then yes — coastal new construction needs WPI-8 windstorm certification, and without it the Texas Windstorm Insurance Association (TWIA) won't issue a windstorm policy, which means you can't insure the home against windstorm. We handle the electrical scope with that compliance in mind. Start here: What Is WPI-8? and TriCoast in Galveston Island.

How much does it cost to wire a new house?

Honestly: there's no one-size price for whole-house new-construction wiring, and we won't quote you a fake range. It depends on the home's size, the plan, the load calc, and the scope. We price it per plan — send your plans, we run a load calculation, scope the wiring, and quote off the real job with no surprise bills. (Whole-house new-build wiring is a different job than a single panel upgrade or EV charger, so those published ranges don't apply here.)

Can you rough-in for an EV charger, generator, or smart-home wiring now so it's ready later?

Yes — and the time to do it is now, while the framing is open. We can run an EV-ready circuit, a generator connection, or structured/smart-home pre-wire during rough-in, so the system is ready when you are instead of becoming a wall-opening retrofit later.

What's the difference between new-construction wiring and remodel/addition wiring?

New-construction wiring is a from-the-ground-up house: service sizing, full rough-in in open framing, and a fresh permit and inspection for the whole electrical system. Remodel and addition wiring ties new work into an existing, already-energized home — different constraints, different scope. If that's your project, head to Remodel & Addition Wiring.
