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 requires Board of County Commissioners approval before covered construction begins but does not publish a dependable decision deadline for Construction Certificates.
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 307-322-1330 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.

N/A; the County requires Board of County Commissioners approval before covered construction begins but does not publish a dependable decision deadline for Construction Certificates.
Platte County publishes no general structural inspection program because it has adopted no building code. The certificate application authorizes County personnel to enter for zoning assessment, evaluation or inspection; coordinate any requested County visit through Planning and Zoning at 307-322-1330. For a guaranteed state electrical inspection in Platte County, contact Wyoming inspector Brian Keithly at 307-254-1081 after obtaining the wiring permit. State Fire Marshal and DEQ septic inspections are separate where applicable.
Platte County has not adopted an IBC-family building code and does not conduct general building-code review in unincorporated areas. Its Construction Certificate is a zoning/land-use approval under the Platte County Planning and Zoning Rules and Regulations. State-regulated projects remain subject to Wyoming's 2024 IBC, IFC, IFGC, IMC and IEBC through the State Fire Marshal, and the 2026 NEC is effective July 1, 2026. The County's current FAQ states that a Construction Certificate is required for a structure built, placed or erected outside town limits when construction cost exceeds $1,000,000; structures at or below that threshold are therefore outside the currently published certificate trigger. Incorporated-town projects must follow the municipality's rules. County zoning, setback, floodplain and special-use requirements, plus separate state fire, electrical, septic and well permits, can still apply regardless of the Construction Certificate threshold.
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.
