A building permit in Gillette is issued by the city's Building Inspection Division, part of Development Services, which administers the full 2024 family of International Codes adopted in the city code and runs plan review and inspections. The state electrical program and the city contractor licence run alongside the city permit.
Gillette's distinctive rule is its licensing. A City of Gillette contractor licence is required for the work regardless of the project's size or duration, and regardless of whether a permit or inspection is even required — so licensing is decoupled from permitting. Applications are reviewed by the city's Board of Examiners, which meets monthly and also serves as the Board of Appeals for the adopted codes, so a contractor plans around that monthly cycle. Fire-suppression permits and inspections run through the Campbell County Fire Department.
This guide covers the city of Gillette, in Campbell County. Work outside the city limits falls to Campbell County; confirm which authority holds the address, since Wyoming enforcement is assumed jurisdiction by jurisdiction.
The contractor licence is required even without a permit. Because Gillette requires a contractor licence regardless of the project's size or duration and whether or not a permit or inspection is required, a contractor confirms the city licence before any work — and plans around the monthly Board of Examiners that approves it.
What requires a building permit in Gillette?
Wyoming has no mandatory statewide building code for private construction. The State Fire Marshal, through the Department of Fire Prevention and Electrical Safety, adopts a set of minimum codes — currently the 2024 International Codes — but those apply chiefly to state-owned buildings, public schools and the places where no local government enforces anything, and the State Fire Marshal is the default authority there. A city or county becomes the building authority by assuming local enforcement; roughly half of Wyoming's counties enforce no building code at all, and on that land there is no building permit. So in Gillette the questions are whether a local department enforces a code, the local contractor licence, and that Gillette licenses contractors regardless of whether a permit is required, with applications approved at a monthly Board of Examiners.
Two things reach across the state regardless of local enforcement. Electrical is the statewide exception: the Department of Fire Prevention and Electrical Safety runs a statewide electrical permit-and-inspection program under the 2023 National Electrical Code, licenses electricians and has authority in all twenty-three counties — though a property owner may wire their own home, not for immediate resale, under state law. And the State Fire Marshal reviews fire and life-safety for covered occupancies such as schools, assembly and state buildings. Wyoming has no statewide general-contractor licence; contractor licensing is local, city by city.
Typically permit required
- A City of Gillette contractor licence for the work, required regardless of whether a permit is needed
- A City of Gillette building permit from the Building Inspection Division for construction, additions and most alterations
- A Wyoming electrical permit and inspection through the Department of Fire Prevention and Electrical Safety — or the city's own certified electrical inspectors in a delegated city
- A local contractor licence from the city, since Wyoming has no statewide general-contractor licence
- The locally adopted building code and amendments, where a local department enforces one
- State Fire Marshal fire and life-safety review for covered occupancies such as schools, assembly and state buildings
Often exempt
- Minor work the adopted code places below the permit threshold — though the contractor licence is still required
- A local building permit in an area with no local building department — roughly half of Wyoming's counties
- A licensed electrician for an owner wiring their own home, not for immediate resale, under state electrical law
- Minor work the locally adopted code places below the permit threshold, where zoning still applies
Whether a local department enforces a code where you are building
Wyoming's building enforcement is assumed locally. A city or county takes it on by adopting standards that meet or exceed the state minimums and employing certified inspectors; where it does, that department administers permits, plan review and inspections within its territory. Where it does not — or loses its certified inspector — authority reverts to the State Fire Marshal. The larger cities run active departments; much of the unincorporated state runs none, and there the only permits are the statewide electrical permit and any state fire review. Beyond that, Gillette administers the 2024 International Building, Residential, Fire, Existing Building, Mechanical, Plumbing and Fuel Gas Codes through its Building Inspection Division, and its licensing rule is unusually broad: a contractor licence is required regardless of the project's size or duration and whether or not a permit or inspection is required. Applications go before the city's Board of Examiners, which meets monthly — a completed application in by the deadline is heard at that month's meeting — and the same Board serves as the Board of Appeals for the adopted codes. Energy-industry cycles have long driven the pace of construction here.
Who handles permitting in Gillette?
The city of Gillette is served by the Building Inspection Division within Development Services, which issues building permits, licenses contractors through the Board of Examiners, administers the adopted 2024 codes, and runs plan review and inspections. Electrical runs through the state, and fire suppression through the Campbell County Fire Department.

Permit types
Residential permits
Houses, additions, alterations, decks and garages inside the city are permitted through the Building Inspection Division under the adopted 2024 codes. The contractor holds a City of Gillette licence — required whether or not a permit is — the electrical is permitted through the state, and Wyoming's wind and snow loads are designed for.
How Wyoming contractor and trade credentials work
Wyoming licenses very little at the state level. There is no statewide general-contractor licence, so a general contractor is licensed by the city where the work is — typically an application, proof of insurance and, in several cities, an examination or a licensing board. The clear statewide credential is electrical: electricians and electrical contractors are licensed by the State of Wyoming through the Department of Fire Prevention and Electrical Safety. Plumbing is handled locally, in the cities that adopt and enforce a plumbing code. In Gillette the local contractor licence is confirmed before a permit issues.
Commercial permits
Commercial and multi-family projects are reviewed under the adopted 2024 International Codes, with contractor licensing through the Board of Examiners and fire-suppression work through the Campbell County Fire Department. Covered occupancies also draw State Fire Marshal fire and life-safety review.
The statewide electrical program and the fire-safety review
Two state processes run alongside a local Wyoming building permit. The Department of Fire Prevention and Electrical Safety issues the electrical permit and inspects the wiring statewide under the 2023 National Electrical Code — except in a delegated city such as Cheyenne or Casper, where the city's own certified electrical inspectors do that work under the state code. And the State Fire Marshal reviews fire and life-safety for covered occupancies. In Gillette the electrical work is permitted and inspected through the state Department of Fire Prevention and Electrical Safety, and fire-suppression work runs through the Campbell County Fire Department.
Gillette permit costs and fees
Gillette scales its building permit to the project, filed through its online portal. The cost item particular to the city is the contractor licence, which is required for the work regardless of whether a permit is, and approved on the Board's monthly cycle.
| Item | Fee or rule |
|---|---|
| Building permit | Scaled to project valuation under the city's fee schedule, filed on the online portal |
| Contractor licence | A City of Gillette licence required regardless of permit, approved at the monthly Board of Examiners |
| Electrical | Permitted and inspected through the state Department of Fire Prevention and Electrical Safety |
| Fire suppression | Permitted and inspected through the Campbell County Fire Department |
Budget the licence before the permit. Because the City of Gillette licence is required for the work whether or not a permit is, and is approved only on the Board of Examiners' monthly cycle, it belongs at the front of the schedule so the monthly meeting does not become the bottleneck.
Trade permits and who may pull them
Trade work in Wyoming divides between a statewide electrical program and locally handled plumbing and mechanical work. Electricians hold a state licence and pull a state electrical permit; plumbers and mechanical contractors are handled by the city that enforces those codes.
Permit required
- Electrical — by an electrician licensed by the State of Wyoming, permitted and inspected through the Department of Fire Prevention and Electrical Safety, or the city's inspectors in a delegated city
- Plumbing — under the plumbing code the city has adopted, where it enforces one
- Mechanical — under the mechanical code the city has adopted, with a city licence where the city licenses the trade
- General contracting — under a city contractor licence, since Wyoming has no statewide general-contractor licence
Typically exempt
- An owner wiring their own home, not for immediate resale, under the state electrical law
- Minor work the locally adopted code places below the permit threshold
How to apply for a Gillette building permit
The larger cities do; roughly half of Wyoming's counties do not, and on that land there is no local building permit.
The city within its limits, or the county where it has assumed enforcement, each with its own adopted edition and amendments; otherwise the State Fire Marshal by default.
From the city where the work is, since Wyoming has no statewide general-contractor licence; several cities license through a board or an examination.
From the Department of Fire Prevention and Electrical Safety, or the city's own electrical inspectors in a delegated city such as Cheyenne or Casper.
To the city building department, against its adopted code, with Wyoming's wind and snow design loads addressed.
City building inspections, the state or delegated electrical inspection, any state fire review, then the certificate of occupancy where a code is enforced.
Review, corrections and what actually causes delay
The Gillette delays that recur are licence-timing delays: a contractor who assumed no licence was needed because the job needed no permit, or an application that missed the Board of Examiners' monthly deadline. Holding the city licence, planning around the monthly Board, and pulling the state electrical permit keep the review on track.
Inspections in Gillette
Where a city enforces the code, building inspections follow the adopted edition — footing, foundation, framing, rough trades, insulation and final — requested from the city against the permit number. Electrical inspection runs through the Department of Fire Prevention and Electrical Safety, or the city's own certified inspectors in a delegated city, and its approval is required before the service is energized. A certificate of occupancy closes the file where a code is enforced. In an area with no local department, the statewide electrical inspection and any state fire review may be the only inspections. In Gillette the building inspections run through the Building Inspection Division against the permit number; electrical is inspected through the state Department of Fire Prevention and Electrical Safety, and fire-suppression work through the Campbell County Fire Department.

Frequently asked questions
Do I need a contractor's licence even if I don't need a permit?
Yes. Gillette requires a City of Gillette contractor licence for the work regardless of the project's size or duration and whether or not a permit or inspection is required. Licensing is decoupled from permitting here.
How does contractor licensing get approved?
Through the city's Board of Examiners, which meets monthly. A completed application received by the deadline is heard at that month's meeting; the same Board also serves as the Board of Appeals for the adopted codes.
Which building codes does Gillette enforce?
The 2024 editions of the International Building, Residential, Fire, Existing Building, Mechanical, Plumbing and Fuel Gas Codes, adopted in Chapter 5 of the city code.
Who inspects electrical and fire-suppression work?
Electrical runs through the state Department of Fire Prevention and Electrical Safety; fire-suppression permits and inspections run through the Campbell County Fire Department. Gillette does not hold delegated electrical authority.
Does the State Fire Marshal review my project?
For covered occupancies — schools, assembly and state buildings among them — the State Fire Marshal reviews fire and life-safety. Most ordinary Gillette projects are handled by the city and county.
Do I need to design for wind and snow?
Yes. Wyoming's wind and snow loads are dominant design factors, and Gillette's adopted code sets the values. Confirm the current design criteria with the Building Inspection Division.
