Renovation permits and contractor licences in Wyoming
Wyoming splits the job. Electricians are licensed by the state, through the Department of Fire Prevention and Electrical Safety, which also issues electrical wiring permits and runs plan review for the building types the statute lists. Contractor licensing and building permits are municipal: Casper and Cheyenne each issue their own contractor licences and their own building, plumbing, mechanical and electrical permits.
Regulators and licensing bodies in Wyoming
These official bodies license contractors, oversee safety or issue permits in Wyoming.
Wyoming Department of Fire Prevention and Electrical Safety
The State Fire Marshal's office, whose stated purpose is to protect life and property from fire and electrical hazards. It licenses apprentice, journeyman and master electricians, issues electrical wiring permits, and carries out the plan review that Wyoming statute requires for certain buildings and installations.
City of Casper Community Development Department
Issues building permits and reviews plans within Casper, and licenses contractors locally. Applications for general and sub contractor, electrical, and plumbing, mechanical and individual contractor licences go to the department for review by the Chief Building Official, and an approved applicant must produce proof of insurance before the licence is issued.
City of Cheyenne Building Division
Issues building, plumbing, mechanical and electrical construction permits within Cheyenne city limits and runs plan review and inspections to enforce the adopted building and fire codes. Licences come in pairs: a company licence and a registered individual qualified supervisor. Everything is handled online.
Trades that need a licence in Wyoming
Electrical work
Electricians hold a state licence, issued by the Department of Fire Prevention and Electrical Safety on the apprentice, journeyman and master pattern. An electrical wiring permit must be obtained before starting new construction or remodelling of any building, mobile home or premises where the work will need a public utility to connect, or disconnect and restore, electrical power.

General contracting and renovation
Contractor licensing in Wyoming is municipal, so the answer depends on your city. Casper issues general and sub contractor licences through its Community Development Department, reviewed by the Chief Building Official, with proof of insurance required before issue. Cheyenne issues a company licence only together with a registered individual qualified supervisor.

Plumbing
Plumbing and mechanical contractors are licensed by the city too. Casper issues plumbing, mechanical and individual contractor licences, and the same department that issues the licence issues the permit and does the inspection, so it is one conversation rather than two.

Building and renovation permits in Wyoming
There is no statewide building permit in Wyoming: your city issues it. Casper requires a permit before new construction, an addition, or a remodel, alteration or repair of an existing structure, reviews building and site drawings against the adopted codes, and works to the 2024 International Codes with amendments in Title 15 of its municipal code. Cheyenne's Building Division issues building, plumbing, mechanical and electrical permits entirely online. Separately, the state Department of Fire Prevention and Electrical Safety issues the electrical wiring permit when a utility has to connect or restore power, and must approve plans before work commences for the building types the statute lists.
