Frequently asked questions for Campbell County
Who handles permitting for this jurisdiction?
Campbell County Public Works Building Division is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
No verified online portal was located in the reviewed public materials. Contact 307-682-1970 and request the current application route before preparing a final submittal.
How long might review take?
Allow 10 business days for commercial plan review when the application needs no corrections; Planning, the Fire Marshal and the Building Division must approve it.
How are inspections scheduled?
Call the Building Division at 307-682-1970 to schedule required inspections. The County performs inspections during construction, notifies the owner and builder of violations, and requires a final inspection and Certificate of Occupancy before an applicable permitted building is occupied. For an optional rural-home Certificate of Occupancy, the published stages include footing, stemwall, service utility lines, rough framing/electrical/plumbing/HVAC, drywall and final. Assigned address numbers must be posted before inspectors will visit. The first two inspections of the same work are included; each subsequent failed reinspection costs $60 and must be paid before scheduling.
Which codes and exemptions should I review?
Campbell County's current commercial checklist requires compliance with the 2024 International Building, Plumbing, Mechanical and Fire Codes, plus applicable county, state and federal requirements. Chapter 4 also governs electrical, mechanical, plumbing, small-wastewater and fire-safety work; small wastewater systems must comply with Wyoming DEQ Water Quality Rules Chapters 11 and 25. The Building Division enforces these rules in unincorporated Campbell County outside Gillette and Wright, while zoning applies only to designated zoning districts and most platted subdivisions. County Chapter 4 exempts one- and two-family dwellings from the general building permit, although special requirements apply in zoned or platted subdivisions and separate electrical, mechanical, plumbing, septic, zoning and floodplain permits may still be required. It also exempts qualifying structures on parcels of 40 acres or more used exclusively for farm/ranch operations, HUD-code manufactured homes, and public, commercial or industrial buildings associated with oil, gas, coal or other mineral extraction. The County does not publish a separate list of cosmetic repair exemptions.
