Quick answer

Solar panels are permitted work in unincorporated Wake County; the county's fee schedule lists them among the projects covered by the single residential permit, and its Solar Panels planning checklist assigns a permit type to every residential case. On an existing home, a roof-mounted system is permitted as a Residential alteration and a ground-mounted system as a Residential non-building structure; on a new build, solar is incorporated into the plans as an accessory structure under Unified Development Ordinance Section 4-70-1 H. The checklist adds an aviation notice step only for commercial arrays larger than half an acre within five miles of a public airport.

How to apply in Wake County

A rooftop solar PV permit application is a combined structural and electrical plan set: a site plan and roof framing details proving the array's mounting can carry its added loads, plus a one line electrical diagram covering listed modules and inverters, disconnects, and the rapid shutdown design. Utility interconnection is a separate approval that runs in parallel with the permit.

What most solar permit applications include:

  • Both a building permit and a separate electrical permit are required, since the array must be designed and installed to the residential code's solar provisions and to the National Electrical Code (IRC R324.3).
  • The plan set identifies listed equipment: PV modules listed to UL 1703 (or both UL 61730-1 and UL 61730-2), and inverters listed to UL 1741, with grid-tied inverters listed for utility interaction (IRC R324.3.1).
  • Structural drawings show that the roof framing is designed to structurally support the array and withstand the gravity loads it adds (IRC R324.4.1).
  • The site plan lays out roof access pathways at least 36 inches wide, plus a ridge setback sized to how much of the roof the array covers, so firefighters retain pathways and ventilation access (IRC R324.6.1, IRC R324.6.2).
  • The one line electrical diagram shows the rapid shutdown method and the location of its single initiation device, since one control point must bring all system conductors down to safe levels (NEC 690.12, NEC 690.56(C)).
  • Interconnecting the array to the utility grid at a defined point of connection is a separate application process from the local building or electrical permit and must be approved before the system can operate (NEC 705.12).
  • Some permitting offices route applications through SolarAPP+, an automated review platform that checks the plan set against code requirements and issues eligible permits instantly (DOE SolarAPP+).

Inspections and closing out your permit

Inspectors verify the installed array against the approved plans, and some agencies run a rough check of roof attachments and penetrations while they are still exposed before the wiring and roofing close them in. The final inspection confirms rapid shutdown, disconnects, grounding, and required labels are installed correctly, and the system cannot be energized until the utility separately approves interconnection.

  1. Where an agency runs a rough or pre-inspection, it checks the array's roof penetrations while they are still exposed, confirming they are flashed and sealed (IRC R324.4.3).
  2. The inspector confirms whether rapid shutdown is required, how it is accomplished, and that it is properly identified (NEC 690.12, NEC 690.56(C)).
  3. PV disconnecting means must be permanently marked and installed where they are readily accessible, which the inspector confirms in the field (NEC 690.13).
  4. Bonding and grounding of the array, including every exposed non current carrying metal part and the grounding electrode system, is checked before sign off (NEC 690.43, NEC 690.47).
  5. At the service equipment, the inspector looks for the required rapid shutdown placard, a labeled diagram showing the initiation device's location in the specified colors and letter sizes (NEC 690.56(C)).
  6. Utility interconnection is inspected and approved separately from the local building department's sign off, and the system cannot be energized until both approvals are in hand (NEC 705.12).

Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Wake County permit portal or by phone at 919-856-6222.

Can a homeowner pull a solar permit themselves in Wake County?
Under North Carolina law (N.C. Gen. Stat. 87-1(a), 87-1(b)(2), 87-14(a)(1), 160D-1113, 160D-1115): A North Carolina homeowner may pull the permit and do the work. G.S. 87-1(a) reaches general contracting only where the cost of the undertaking is $40,000 or more, and G.S. 87-1(b)(2) then exempts a person who constructs or alters a building on land that person owns, provided the building is intended solely for occupancy by that person and his family after completion and the person complies with G.S. 87-14. There is no outright ban on selling, but there is a look-back that works like one: if the building is not occupied solely by the person and his family for at least 12 months following completion, the statute presumes the person did not intend the building solely for that occupancy, which defeats the exemption. G.S. 87-14(a)(1) requires an owner claiming the exemption to execute a verified affidavit attesting that they own the property, that they will personally superintend and manage all aspects of the construction and will not delegate that duty to anyone unlicensed, and that they will be personally present for all inspections required by the State Building Code unless a licensed architect sealed the plans. The inspector transmits that affidavit to the Licensing Board, and if the Board determines the exemption was not available the building permit is revoked under G.S. 160D-1115. The exemption removes the general contractor license requirement only. It does not exempt the work from permits or inspections, and G.S. 160D-1113 provides that when a permit is held by an owner exempt under 87-1(b)(2), no inspection may be conducted without the owner present unless an architect sealed the plans. Confirm how Wake County applies this before you apply.
