North Carolina Electrical Permit Fee Estimator

Estimate electrical permit fees in North Carolina based on the type of electrical work and the value of construction. Fees are calculated per the North Carolina State Building Code and local jurisdiction schedules.

Project Type

New Residential Construction New Commercial Construction Addition / Alteration / Renovation Temporary Power Service Upgrade / Panel Change Low Voltage / Signal Systems

Electrical Construction Value ($)

Total value of electrical work including labor and materials.

Conditioned Square Footage (sq ft)

Used for new residential construction fee calculation.

Service Size (Amps)

100A 150A 200A 400A 600A 800A 1000A 1200A+

Temporary Service Size (Amps)

60A 100A 200A 400A

Jurisdiction Type

State (NCDOI) Inspected Local Jurisdiction (e.g. Charlotte, Raleigh)

Some local jurisdictions apply a multiplier or surcharge on top of state fees.

Local Jurisdiction Fee Multiplier

Common range: 1.05–1.50. Check with your local building department.

Number of Additional Inspections Requested

Each re-inspection or additional inspection: $50.00 per NCDOI schedule.

#### Formula

Value-Based Projects (Commercial, Additions, Low Voltage):

New Residential: max(sq ft × $0.10, $75.00)

Service Upgrade: Flat fee by amperage ($75–$350)

Temporary Power: Flat fee by amperage ($50–$120)

NC Building Code Council Surcharge: Base Fee × 10%

Local Jurisdiction: (Base Fee + Surcharge) × Local Multiplier

Additional Inspections: Number of inspections × $50.00

Total = Adjusted Subtotal + Additional Inspection Fees

#### Assumptions & References

Fee schedule based on North Carolina Administrative Code 11 NCAC 08 .1000 and the NCDOI Electrical Inspection Fee Schedule.
The 10% NC Building Code Council surcharge is mandated by NC General Statute § 143-151.15 and applies to all electrical permit fees statewide.
Re-inspection and additional inspection fees are $50.00 each per NCDOI schedule.
Fees are subject to change. Always verify current fee schedules with the NC Department of Insurance or your local building department.
