The Electrical Subcontractor You Choose Affects Every Wall in the Build
In new construction, the electrical work happens before the drywall goes up and isn’t visible to the homeowner until something doesn’t work after move-in. That invisibility makes choosing the right electrical subcontractor more important, not less. Errors in the rough-in phase, wrong wire gauge, missed home runs, connections that don’t meet inspection standards become expensive problems after the walls are closed.
This guide is written for builders, general contractors, and homeowners managing their own build in the Tulsa, Broken Arrow, and Owasso markets. It covers what professional new construction electrical work looks like, what to look for in a subcontractor, and what the inspection process involves.
The Phases of New Construction Electrical Work
Temporary Power
Before any framing begins, the job site needs temporary power for tools and equipment. This involves installing a temporary service entrance or power pole and coordinating with the utility for connection. Getting this right from the start sets the tone for the project.
Underground Rough-In
In most new construction, electrical conduit runs underground to the garage, HVAC equipment pads, and outbuildings before the slab is poured. This phase has zero tolerance for error once the slab is down, routing conduit underground requires cutting.
Rough-In (First Fix)
The rough-in phase is when the electrical system’s architecture is built: panels are installed, wire is run to every device location, boxes are placed at the correct heights and positions, and all home runs are landed at the panel. This is the phase that requires the most experience and planning. The difference between a clean, organized rough-in and a chaotic one shows up for the life of the building.
Rough-In Inspection
Before drywall is installed, the rough-in must pass inspection by the local authority having jurisdiction (AHJ). In Tulsa, this is the City of Tulsa Development Services; in BrokenArrow and Owasso, it’s their respective building departments. The inspection covers wire sizing, box placement, ground fault protection requirements, smoke detector locations, and other code items. Failing the rough-in inspection delays the entire project.
Trim-Out (Second Fix)
After drywall and painting, the trim-out phase installs all devices: outlets, switches, plates, light fixtures, panel breakers and directories, and appliance connections. This is the phase that’s visible to the homeowner, and it’s where the care taken in the rough-in either pays off cleanly or creates complications.
Final Inspection
The final electrical inspection covers the completed system under load, all installed fixtures and devices, a labeled panel, and an energized system. Passing final inspection is a condition of the Certificate of Occupancy
What to Look for in a New Construction Electrical Contractor
- Experience with current NEC code and local jurisdiction amendments
- A track record of passing rough-in and final inspections on the first attempt
- Organized rough-in work: properly supported wiring, clean home runs, clearly routed circuits
- Panel work that’s labeled accurately and makes sense to whoever will live with it
- Communication with the GC and owner about timeline, any field conditions that affect scope, and inspection scheduling
