Permit fees in Mount Holly
Gaston County’s FY26 Building and Development Services Fee Schedule sets the building and trade fees; Mount Holly’s zoning fees are separate City charges. County building permits are priced on construction value, taken from the current ICC valuation tables per square foot or the contract price, whichever is greater; unheated space, garages, porches and decks are included in the square footage.
| Project | Fee |

Commercial plan review is 20% of the permit fee for the first review, and fire plan review runs from $90 to $450 depending on building size. Starting work without a permit doubles the fee.
Electrical, plumbing, mechanical and gas permits
Gaston County issues the electrical, plumbing and mechanical permits for Mount Holly projects; the City zoning permit does not cover trade work. A residential single-trade permit is $90, and so is a water heater or HVAC change-out. Commercial trade, fire and sprinkler permits that are not part of a building permit are priced on project cost using the County’s valuation table.
Alliance handles electrical permit applications for contractors here. More on this: who pulls the electrical permit.
Application documents and plan review
For the City zoning compliance permit, the residential application asks for the parcel ID, the type of work (new construction, addition, fence and its height, accessory building, pool or renovation) and a site plan sketch under Section 15.2.1 of the Zoning Ordinance showing lot lines, existing and proposed structures and their setback distances. You also confirm with City Utilities whether backflow and cross-connection control is needed (Cross Connection Inspector, 704-951-0074 ext. 104) and, for a demolition, arrange removal of the water meter.
The City has 10 business days to review a zoning permit and works them in the order received. The County submittal usually involves engineered or architectural plans reviewed by Building Inspections and the Fire Marshal, and no construction may begin until the County permit is issued. A residential re-review or re-stamp of lost plans costs $45.

Local details that matter in Mount Holly
Gaston County lists Mount Holly among the towns where it provides building inspections and permitting, while the City’s Planning & Development Department at 400 East Central Avenue handles zoning. The City’s zoning permit confirms only that the use meets the Zoning Ordinance, so it does not replace the County building permit.
Fences, decks, sheds, garages and pools all need a City site plan sketch with setbacks before the zoning permit is issued.
North Carolina building code
The 2018 North Carolina State Building Code family applies statewide, with the 2020 North Carolina Electrical Code; one- and two-family homes and townhouses still use the 2017 edition. The 2024 code has been delayed and cannot take effect before late 2027. The NC State Building Code and the delayed 2024 edition
