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
The State Fire Marshal accepts or rejects a plan-review submission for review within five business days and completes review of a complete accepted submittal within 21 business days; resubmittals are reviewed within 10 business days after receipt or the original 21-day period, whichever is later. County review times are N/A.
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 307-777-7288; Johnson County Planning Department 307-684-1907 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
This record is marked State Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.

For a guaranteed state electrical inspection in Johnson County, obtain the wiring permit through the state portal and contact State Electrical Inspector Matt Mullen at 307-752-0348. State fire/life-safety plan-review projects receive construction inspections and must pass before a Certificate of Occupancy or Letter of Compliance. County septic inspections must be arranged through the Planning Department at 307-684-1907 at least 24 hours before backfilling; a Certificate of Completion is required when an inspection was not completed.
Johnson County reviews land development, subdivisions, lot divisions and exemptions and administers rural addressing, septic and floodplain development, but its zoning regulations remain a draft that the commissioners have not adopted and the County publishes no general building-permit or building-inspection program. For projects within Wyoming State Fire Marshal jurisdiction, the state enforces the 2024 International Fire, Building, Fuel Gas, Mechanical and Existing Building Codes and, effective July 1, 2026, the 2026 National Electrical Code. County subdivision, floodplain and small-wastewater rules apply separately. N/A for a general county building permit because Johnson County publishes no such program and its zoning regulations remain unadopted. State Fire Marshal plan review is limited to specified public and life-safety projects, including government buildings, schools, public-access buildings over 5,000 square feet, larger child-care facilities, multistory and assembly occupancies, qualifying remodels and occupancy changes, fire-protection systems, alternative energy, aboveground fuel tanks, commercial kitchen hoods, spray-finishing work and RV/camping/mobile-home park site plans. Other private work may still require a state electrical permit or County septic, floodplain, subdivision or addressing approval.
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.
