Gaston County building permits are issued by Building & Development Services for unincorporated county land and for 14 municipalities — Gastonia among them, since the city folded its inspections into the county in August 2022. The City of Gastonia no longer accepts construction permit applications at all.
What it does still issue is the zoning permit, and that is the sequence: city zoning first, county building second. Miss it and the county application does not proceed. The same logic applies across the other served towns, where a copy of the municipal zoning permit accompanies the county request.
Applies to unincorporated Gaston County and the 14 municipalities the county inspects. Floodplain review covers a shorter list than building inspections.
The inspection list and the floodplain list are not the same list. The county inspects 14 municipalities but reviews floodplain for eight. Gastonia, Bessemer City, Cramerton, Mount Holly, and Ranlo handle their own floodplain review.
What requires a permit in Gaston County?
A Gaston County building permit is required before most construction, alteration, repair, demolition, or change of occupancy. Gaston is a county-led jurisdiction: the Building Inspections department enforces the state building code for unincorporated county land and for the 14 municipalities it lists, a consolidation extended when Gastonia folded its inspections into the county in August 2022. Kings Mountain, which reaches into Gaston from Cleveland County, is not on the county’s list.
Permit required
- New construction, additions, and accessory structures above the local size threshold
- Structural and load-bearing alterations and repairs
- Residential remodels within the existing footprint that touch structure or systems
- Commercial new builds, additions, upfits, remodels, and change of use
- Electrical service changes, panel work, and most wiring alterations
- Plumbing additions, repipes, gas piping, and non-identical water heater swaps
- Mechanical and HVAC installations and changeouts
- Land disturbance of 1 acre or more, which pulls in erosion and sediment control
Typically exempt
- Nonstructural work costing $40,000 or less in a single-family home, farm building, or commercial building (G.S. 160D-1110(c))
- Replacement windows, doors, exterior siding, and porch/deck pickets, railings, stair treads, and decking
- Like-for-like plumbing swaps that keep size and capacity, and like-kind light fixtures, receptacles, and switches
- Same-spec water heater changeouts installed by a licensed contractor
- Painting, flooring, cabinetry, and other cosmetic work

Gaston County building department: who handles permitting
Gaston County Building & Development Services runs building inspections from 128 West Main Avenue in Gastonia, covering unincorporated Gaston County and 14 municipalities: Belmont, Bessemer City, Cherryville, Cramerton, Dallas, Delview, Gastonia, High Shoals, Lowell, McAdenville, Mount Holly, Ranlo, Spencer Mountain, and Stanley. Gastonia joined that list on August 29, 2022, and applications for construction permits are no longer accepted at the city.
Here is the boundary that gets misapplied. Building inspections cover all 14 — but floodplain review covers a shorter list: Belmont, Cherryville, Dallas, High Shoals, Lowell, McAdenville, Stanley, and Spencer Mountain. Gastonia, Bessemer City, Cramerton, Mount Holly, and Ranlo are inspected by the county but handle floodplain review themselves. Assuming the two lists match is how a floodplain project ends up reviewed by nobody.

If the property is inside Belmont, Bessemer City, Cherryville, Cramerton, Dallas, Gastonia, High Shoals, Lowell, McAdenville, Mount Holly, Ranlo, Spencer Mountain, or Stanley, a copy of the municipal zoning permit is required when you request the county building permit. In Gastonia, get the city zoning permit first for most work (new buildings, additions, decks, accessory buildings, pools, demolition, signs, solar), then apply to the county; single-trade and equipment change-out permits, residential interior renovations and temporary power go straight to the county. City zoning questions go to (704) 866-6729.
This guide covers Gaston County, North Carolina, seated in Gastonia. Gaston County, Kentucky does not exist, but the town of Gaston in Northampton County, NC does — and Gastonia, the city, is a separate entry from Gaston, the county, in most permit databases.
Gaston County permits: record types and what each covers
Gaston publishes complete permit packages by project type rather than single-page applications, so picking the right Gaston County permit package is the first step. These are the records the department issues:

Solar in Gaston follows the same municipal-zoning-first rule as everything else: inside a served town, the zoning permit precedes the county electrical and structural review. Ground-mounts in a mapped floodplain need to establish which body is doing the floodplain review before anything else.
Roofing permits in Gaston
Reroofs across all 14 municipalities and unincorporated Gaston are county permits. A roofer who worked City of Gastonia permits before the 2022 consolidation and never opened a county account will need one — the city cannot take the application any more.
Solar covenants and the roofing permit exemption are set by state law, and utilities run interconnection on their own timeline. North Carolina rules
Gaston County permit cost
Gaston County building permit fees follow the county's published fee schedule, with the building record and each trade permit charged separately. Municipal zoning permits carry their own fees payable to the town rather than to the county.
Budget for the upstream approvals as well. Land disturbance of 1 acre or more requires a comprehensive erosion and sediment control plan issued by Gaston County Natural Resources, which is a separate submittal with its own timeline.
| Fee component | How it works |
|---|---|
| Building permit | County fee schedule by record type and scope |
| Trade permits (E/P/M) | Charged separately per trade record |
| Municipal zoning permit | Paid to the town; required with the county permit request |
| Erosion and sediment control | Through Gaston County Natural Resources at 1 acre or more |
| Re-inspection | Charged on failed inspections before final or certificate |
| Portal access | Dual authentication required on the self-service portal |

Gaston County trade permits
Gaston County trade permits for electrical, plumbing, and mechanical work are separate records pulled by the state-licensed contractor performing the work, filed through the county's self-service portal.
Electrical permits
Required for services, panel upgrades, circuits, EV chargers, and solar interconnection. Electrical work takes a contractor licensed by the NC State Board of Examiners of Electrical Contractors, unless owners wire their own home that is not for sale or rent.
Plumbing permits
Required for new piping, repipes, fixtures, gas piping, and non-identical water heater changeouts by a state-licensed contractor.
Mechanical (HVAC) permits
Required for all installations and changeouts, including like-for-like swaps, plus ductwork and refrigeration, by a state-licensed heating contractor.
Owner-builder route
Gaston includes the statutory licence-exemption affidavit in its permit packages. Read it before signing — willfully committing perjury in an affidavit taken pursuant to law is a Class F felony under G.S. 14-209.

Get a free quote →Gaston County permit application: how to apply step by step
Here is how to get a building permit in Gaston County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Establish which of the 14 served municipalities the parcel is in, or whether it is unincorporated — and check whether that town does its own floodplain review.
If the property is inside a served town, obtain the zoning permit first. In Gastonia this is a hard prerequisite to the county application.
Gaston publishes complete packages by project type — residential remodel, residential new, commercial. Download the matching one and complete every form in it.
At 1 acre or more of land disturbance, obtain the comprehensive erosion and sediment control plan from Gaston County Natural Resources before you submit.
File the package with plans titled For Construction, bound into the required file sets. Dual authentication applies at login.
Pay the county fees, request inspections against the permit, and run through to your certificate of occupancy.
Inspections in Gaston County
Gaston County inspections are requested through the self-service portal against your permit record, including for construction permits that were originally issued by the City of Gastonia before the 2022 consolidation. Typical checkpoints run footing and foundation, rough-in trades, framing, insulation, and final.
Contractors who worked on Gastonia city projects before the consolidation and have never created a county account will need one — the city no longer accepts construction permit applications or inspection requests. If a local government reviews residential plans at all, G.S. 160D-1110(b) requires the initial review within 15 business days of submission — and if it slips past 20 business days, the jurisdiction must refund 10% of the total permit fee for every business day of delay, up to 10 days (a full refund). The same subsection bars requiring an engineer's or architect's seal on one- and two-family plans unless the code itself demands it.
State law sets how long a North Carolina permit stays valid and when changes need written approval. North Carolina rules

Who issues building permits in Gastonia, NC?
Gaston County Building & Development Services. The City of Gastonia moved construction permitting to the county on August 29, 2022, and no longer accepts construction permit applications. The city still issues the zoning permit that has to come first for most projects.
Which municipalities does Gaston County inspect?
Unincorporated Gaston County plus 14 municipalities: Belmont, Bessemer City, Cherryville, Cramerton, Dallas, Delview, Gastonia, High Shoals, Lowell, McAdenville, Mount Holly, Ranlo, Spencer Mountain, and Stanley.
Does Gaston County handle floodplain review everywhere it inspects?
No, and this is the boundary people get wrong. Floodplain review covers a shorter list — Belmont, Cherryville, Dallas, High Shoals, Lowell, McAdenville, Stanley, and Spencer Mountain. Gastonia, Bessemer City, Cramerton, Mount Holly, and Ranlo run their own floodplain review despite being inspected by the county.
Do I need a zoning permit before my Gaston County building permit?
If the property is inside one of the served municipalities, yes — a copy of the town’s zoning permit is required with the county building permit request. In Gastonia the city zoning permit comes first for new construction, additions, accessory buildings, pools, solar and similar work; single-trade and change-out permits, residential interior renovations and temporary power go directly to the county.
How do I run a Gaston County permit search?
Through the county's self-service permitting portal, which has required dual authentication at login since October 1, 2024. Existing users had to re-authenticate their accounts at first login after that date.
When does erosion and sediment control apply in Gaston County?
At 1 acre or more of land disturbance, which requires a comprehensive erosion and sediment control plan issued by Gaston County Natural Resources. Below that threshold the control form inside the permit package generally suffices.
What does a Gaston County building permit cost?
Fees follow the county's published schedule and vary by record type and scope, with trade permits charged separately and municipal zoning permits paid to the town. Confirm the current schedule before budgeting.
Can I act as my own general contractor in Gaston County?
North Carolina allows an owner-builder exemption in defined circumstances, and Gaston includes the statutory affidavit in its permit packages. Be careful: if the licence board determines you were not entitled to claim it, the permit issued on that claim is revoked — and willful perjury in a statutory affidavit is a Class F felony.
When is a general contractor licence required in Gaston County?
On projects of $40,000 or more, under G.S. 87-1 and the NC Licensing Board for General Contractors, with tiers capping single-project value at $750,000, $1,500,000, or without limit excluding land cost.
I have an old City of Gastonia permit — who inspects it now?
Gaston County. Inspections for construction permits that were active with the city at consolidation are requested through the county's self-service portal. Contractors without a county account need to create one.
How do I submit commercial plans in Gaston County?
Plans have to be titled For Construction and bound into the file sets the commercial package specifies. An incomplete set delays the commencement of plan review rather than entering the queue with comments.
When does a Gaston County building permit expire?
Six months after issuance if work has not commenced, and immediately if work is discontinued for 12 months, under G.S. 160D-1111. Changes from approved plans need written approval from the inspection department first.
