Wyoming uses a narrow state model. Only one construction trade is licensed at the state level: electrical. The Wyoming Department of Fire Prevention and Electrical Safety (inside the State Fire Marshal's office) issues Apprentice, Journeyman, Residential Journeyman, Master, Residential Master, and Electrical Contractor licenses under Wyoming Statutes Title 35 Chapter 9 Article 1. Source: WY State Fire Marshal Electrical Safety (https://wsfm.wyo.gov/electrical-safety) and Wyoming Statutes Title 35 (https://wyoleg.gov/statutes/compress/title35.pdf). Trades not state-licensed. - Plumbing. No statewide plumbing license. Regulated at the municipal level (Cheyenne, Casper, Laramie, Gillette, Jackson, and other cities) via city plumber registration programs. - HVAC / mechanical. No statewide HVAC license.

No statewide trade-license bond applies at the State Fire Marshal level. Public works projects require payment and performance bonds under WS 16-6-112. Municipal plumbing and mechanical registrations may carry small city bonds; verify with the issuing city. Renewal and CE. Wyoming electrician licenses renew annually. 16 hours of approved CE every three years for Journeyman and Master Electricians, including NEC update instruction. Reciprocity. Wyoming has journeyman-to-journeyman reciprocity with multiple neighboring states under WS 35-9-123 and department rule. Verify the current reciprocity list on the WY Fire Marshal Electrical Safety page. Unlicensed contracting. Performing electrical work requiring a state license, without holding the appropriate State Fire Marshal credential, is a violation under WS 35-9 and can result in civil penalties, cease-and-desist orders, and referral for misdemeanor or felony prosecution in serious cases. Municipal plumbing and mechanical unlicensed-work enforcement operates at the city level.
