Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; the County states that holidays and high-volume periods affect review time but does not publish a dependable building-permit turnaround target.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call 307-235-9435 if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
Natrona County Building & Inspection Department is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 307-235-9435.
N/A; the County states that holidays and high-volume periods affect review time but does not publish a dependable building-permit turnaround target.
After permit issuance, call the Building Department at 307-235-9435 at least 24 hours before the desired inspection and obtain every inspection required for the project. Inspections are usually available the next business day, excluding weekends and holidays, but may take up to 48 hours during busy periods. Only a morning or afternoon arrival window may be available. Roofing applicants must photograph decking and underlayment because the County does not inspect those stages before final inspection.
2024 International Building Code, 2024 International Existing Building Code, 2024 International Fire Code, 2024 International Fuel Gas Code, 2024 International Mechanical Code, 2024 International Plumbing Code and 2024 International Residential Code, with Natrona County resolutions and amendments; 2023 National Electrical Code. Ordinary cosmetic finish work such as painting, papering, tiling, carpeting, cabinets and countertops is exempt when it does not alter structural members or regulated plumbing, electrical, mechanical or life-safety systems. Fences up to seven feet high do not require a building permit but must comply with zoning. Emergency equipment replacement or repair may proceed, with the application due the next business day. The County advises applicants to verify sheds because every shed needs a zoning certificate; current County materials do not establish a reliable building-permit size exemption for sheds.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
