New Construction Electrician in Twin Falls, Idaho — Homes, Additions & Buildouts
Electrical work on a new build happens in stages, and every stage has an inspection. We handle the service, rough-in, finish and inspections for new homes, additions and commercial buildouts in Twin Falls County.
Stage by stage, from service to final inspection
Plan and load calculation
We review the plans, size the service and panel, and plan circuits, lighting and special loads.
Service and utility
We coordinate the service with Idaho Power or MVEC and install the meter base and panel.
Rough-in
Wiring in the framing, boxes, home runs and low-voltage rough-in — then the rough-in inspection before walls are closed.
Finish and final
Devices, fixtures, panel labeling and testing — then the final inspection.
Homeowners, builders and business owners
New homes
Whole-house electrical from service to switch plates, planned for today’s loads such as EV charging and heat pumps.
Additions and remodels
New rooms, finished basements and accessory buildings tied cleanly into your existing panel — or a new subpanel.
Commercial buildouts
Tenant spaces, offices, shops and restaurants. See commercial electrician.
Build in the electrical you will want later
- A 200A service or larger if you expect an EV charger, heat pump or shop — see our panel size guide.
- EV-ready garage — a 240V circuit or conduit now is far cheaper than trenching later. The 2023 NEC changed what is expected in garages.
- Exterior and landscape lighting circuits and conduit before concrete and landscaping.
- Surge protection at the panel — see surge protection.
For commercial tenant buildouts, our cost guide lists typical electrical at $8 – $25 per square foot, with office space lower and restaurants higher.
Frequently asked questions
When should I hire the electrician for a new build?
Early. Bringing us in at the planning stage lets us size the service, plan circuits and coordinate the utility before framing, which avoids rework.
How many inspections are there?
Typically a rough-in inspection before walls close and a final inspection when the work is complete. We schedule both.
Do you coordinate with Idaho Power or MVEC?
Yes. See the Idaho Power service upgrade process and MVEC vs Idaho Power.
Can you work with my builder or general contractor?
Yes. We coordinate schedules and inspections with builders and general contractors.
What does new construction electrical cost?
It depends on size, layout and finishes. We price in writing from the plans — see our cost guide for reference ranges.
