Who needs a build-out and when

The trigger is usually a change, not a failure. A new tenant signs a lease. A restaurant, office or shop gets a different floor plan. Equipment arrives that the old circuits were never sized for. Any of those means wiring is being installed, altered or extended, and that's the point where the work needs a plan and a permit.

A few conditions push a space from "needs a look" to "needs a plan": breakers with no labels, a panel with no open spaces for the loads you're adding, or walls that several earlier tenants have patched. That last one is common. We'd rather map it before you build around it.

How we scope it

We start with the space and the load: what's going in, where it sits, what runs at the same time, and whether the existing service and panel can carry it. Three-phase switchgear comes into the conversation when the demand or the equipment calls for it. For a typical suite, the answer is often circuit breakers in a panel sized to what you're adding, with room left over.

Our written quote lists what's included: panels and breakers, circuits, the protection each location needs, labeling, testing and the permit. If your landlord, a general contractor or other trades are involved, we say up front what has to happen before we can start and what can't happen until we're done. A build-out is a construction job, and the electrical sequence has to fit around everyone else's.

What it costs and what moves the number

Tenant build-out electrical runs about $8 to $25 per square foot. On a 1,000 square foot space, that's roughly $8,000 to $25,000. A small open suite sits near the bottom and a chopped-up space full of equipment sits near the top. Give us the square footage and what's going in and we can narrow that range on the phone, then lock in the figure after we walk the space.

Price goes up with heavier equipment loads, more circuits per square foot, a panel or service that needs to be added or replaced, three-phase gear, and layouts with lots of small rooms and long runs. It comes down when the space is open, the existing panel has capacity, and the plan is settled before we start. Changes after walls are closed cost more than changes on paper, so a layout that moves halfway through is the fastest way to push a job past its quote.

How the work goes, start to finish

Once the plan and permit are set, we run the circuits and set the panel and breakers. Then comes the termination work: conductors land at the panel, the lugs are torqued to specification, and every circuit gets labeled. Labeling sounds minor, but it's what the next electrician, or you at 6 a.m. with a dead outlet, will rely on.

Then we test. Every circuit gets checked, along with the GFCI and AFCI protection the locations require. We look at load balance across the phases so one leg isn't carrying the building. The final inspection is arranged before the system is energized, not after.

How long all that takes depends on square footage, how many circuits, whether switchgear is involved and how quickly the inspection can be scheduled. Once we've seen the space, the schedule goes in the quote.

Permits and code

Racine requires an electrical permit whenever wiring is installed, altered, extended or connected to electrical equipment. The city issues those permits to properly licensed electrical contractors, so this isn't a form a tenant or landlord files on their own. Work follows Wisconsin's SPS 316, which adopts the 2023 National Electrical Code with state-specific provisions. That's the standard the finished job is inspected against.

One local note: hard winter freezes cycle slabs, foundations and pipes here, so when we route feeders and conduit we look at the condition of the building, not just the drawings. Anything unexpected we find with the walls open goes to you before it goes into the price.
