Building a new home in North Carolina involves three inspection stages on the electrical side. Most homeowners and builders know that an inspector comes out, but the sequencing, what gets inspected at each stage, and how the contractor coordinates around other trades is less familiar. I want to walk through the entire process from the permit application through final inspection so you know what to expect and where the decisions happen.

Before rough-in: the permit and temporary power

The electrical permit is pulled before any wiring starts. In Cabarrus County, Union County, and most Piedmont jurisdictions, the permit is pulled by the licensed electrical contractor, not the homeowner or general contractor. Owner-builder permits are available in NC for homeowners doing their own work on their primary residence, but for homes built by a contractor or for sale, the permit must be in the contractor’s name.

The permit application requires a description of the work: total square footage, number of circuits, service size, and the location and amperage of any specialty circuits for HVAC, EV chargers, generators, pools, or hot tubs. For a standard residential permit, the fee is based on the value of the work and the number of inspections scheduled. In Cabarrus County, a typical new single-family home permit runs $200 to $400 for the electrical permit alone.

Early in construction, before framing is far along, the electrical contractor installs the temporary power service. This is a meter base, a main breaker, and two or three outlet circuits mounted on a treated post near the electrical service entry point. The utility runs a service drop to the meter, and construction crews have usable power for tools, site lighting, and equipment. The temporary pole uses the same service entry location that the permanent service will use, so there is no redundant work when the permanent service is installed.

The rough-in phase: what gets installed and inspected

Electrical rough-in happens after framing is complete, typically before or concurrent with plumbing and HVAC rough-in. The electrical contractor installs all wiring, boxes, panels, and conduit during this phase. Nothing is covered by drywall until the rough-in inspection passes.

During rough-in on a standard 200A single-family home in NC, here is what the electrician installs:

• The main panel and sub-panels if applicable. The main distribution panel, a 200A or larger loadcenter, is mounted in the mechanical room, utility room, or garage. Sub-panels for detached garages, workshops, or large additions are also roughed in during this phase. Panel locations must have a minimum 36-inch clearance in front per NEC 110.26.
• Service entrance conductors. The conductors from the meter base to the main panel, either through conduit on the exterior of the home or through the sill plate and wall cavity to the panel location. These are typically 2/0 AWG aluminum for a 200A service or 4/0 AWG aluminum for a 320A service.
• Branch circuit wiring throughout the home. Every circuit is wired from the panel to its load locations. A standard 2,000 square foot home has 30 to 40 branch circuits covering general lighting, small appliance circuits in the kitchen, bathroom GFCI circuits, dedicated circuits for the refrigerator, dishwasher, garbage disposal, HVAC disconnect, dryer, range, and outdoor circuits for HVAC and any exterior outlets.
• Low-voltage wiring. Cat6 data drops, speaker wire, doorbell wiring, and any pre-wired security camera runs are installed during electrical rough-in because the walls are open. Low-voltage wiring is typically not part of the electrical permit but happens in the same phase for efficiency.

The rough-in inspection happens after all wiring, boxes, and panels are installed and before drywall. The inspector checks wire stapling, which in NC must be within 12 inches of each box and every 54 inches along the run, box fill calculations, cable protection through framing members, and that each circuit is identifiable at the panel. The inspector does not check conductor connections at this stage because they are typically not made until trim-out. The rough-in inspection is typically scheduled 1 to 3 business days after the electrical contractor calls it ready.

Service inspection and utility coordination

The service inspection, sometimes called the meter inspection, verifies the permanent service entrance installation before the utility company will set the permanent meter. This inspection covers the meter base installation, the service entrance conductors, the grounding electrode system, and the main panel installation. In NC, the service inspection is often combined with the rough-in inspection on residential projects, but on larger projects or where the utility requires it, it may be a separate visit.

Coordinating with Duke Energy or Duke Progress in the central NC area is straightforward for standard 200A residential services. The contractor submits a service order with the utility, which schedules the meter set after the inspection approval. The utility typically sets the permanent meter within 3 to 7 business days of receiving the approval from the inspections department. During that window, construction crews continue working off the temporary service.

For services over 200A, particularly 320A or 400A services that require the utility to set a larger meter and sometimes upgrade the transformer, the utility coordination timeline can extend to two to four weeks. Plan for this on any project requiring high-capacity service. The decision to install a 320A service versus 200A should happen at permit application, not mid-construction.

Contractor coordination during rough-in

The electrical contractor coordinates most directly with the HVAC contractor and the plumber during rough-in. HVAC units require disconnect boxes within sight of the equipment, within 50 feet, and on a dedicated circuit sized to the equipment’s nameplate. The size and location of the disconnect must be confirmed with the HVAC contractor before the electrician runs the circuit. Running a 40A circuit to the wrong location because the HVAC contractor changed equipment specifications after rough-in started is a common source of rework.

Bathroom layout requires the electrician and plumber to coordinate around shared wall cavities. Bathtubs and showers require GFCI protection on any outlet within 6 feet of the water edge, and exhaust fan circuits are in the same stud bays as plumbing runs. Neither trade can rough in without knowing the other’s planned locations.

Kitchen layout coordination is the most complex because kitchen circuits are defined specifically by NEC and NC amendments. The countertop outlet circuits are two 20A circuits minimum, GFCI protected, serving countertop outlets on both sides of the kitchen. The refrigerator gets a dedicated 20A circuit. The dishwasher gets a dedicated 20A circuit. The disposal gets a dedicated 20A circuit or shares with the dishwasher depending on code edition. The range requires a dedicated 240V circuit, typically 50A. Getting all of these circuits positioned correctly before drywall requires an accurate kitchen layout from the general contractor early in the project.

Trim-out and final inspection

Trim-out is the phase where outlets, switches, fixtures, and devices are installed after drywall and paint are complete. The electrician makes all final connections at the panel, installs devices and covers, mounts fixtures, and connects appliances. GFCI and AFCI breakers or devices are installed at this phase per their required locations.

The final inspection is the most thorough. The inspector checks every outlet for correct wiring polarity, every GFCI device for proper function with the test button, AFCI protection where required, proper torquing of panel connections, and the panelboard directory showing each circuit’s load. The inspector also verifies that the permanent service is properly installed and that the grounding electrode system is complete and bonded.

A common final inspection issue is incomplete panel directories. Every breaker must be permanently labeled with the load it serves. Handwritten tape is not acceptable. Most inspectors require typewritten or printed labels. Having the directory complete before the inspector arrives saves a callback visit.

What homeowners can do themselves in NC

An owner-builder in NC, meaning someone building or substantially improving their own primary residence, can pull an owner-builder electrical permit and do the wiring themselves. The homeowner must occupy or intend to occupy the home. Owner-builder permits are not available for rental properties or homes being built for sale. The work must pass all inspections just as licensed contractor work would.

For homeowners who want to reduce cost on a new construction project by doing some of the electrical themselves, the work that translates best is low-voltage rough-in, fixture installation after trim-out, and device installation in finished spaces. The panel work, service entrance, and the circuits for HVAC and specialty loads are typically better left to a licensed contractor because the inspection requirements and the consequences of error are higher.
