Wyoming takes a different approach to plumbing regulation than most US states. There is no statewide plumbing licence in Wyoming and no state agency that issues, renews, or enforces plumbing credentials. Licensing authority rests entirely with individual cities, towns, counties, and other local government entities.
Statewide Licensing
No statewide plumber licensing. Wyoming does not issue statewide plumbing licences. Plumbing licensing authority is delegated entirely to individual cities, towns, counties, and other local government entities. There is no Wyoming state agency that issues, maintains, or regulates plumbing licences. Requirements — including credential types, examinations, fees, experience standards, and renewal conditions — vary by jurisdiction and must be confirmed directly with the relevant local authority. Wyoming does have statewide licensing in some other trades — electrical work, for example, is regulated by the Wyoming Department of Fire Prevention and Electrical Safety. Plumbing does not have an equivalent statewide framework; licensing requirements are administered locally and therefore vary by jurisdiction.
Continuing Education
CE requirements vary by local jurisdiction — confirm with the relevant authority.
No statewide CE requirement exists because there is no statewide plumbing licence. Individual local jurisdictions may impose CE requirements as a condition of licence renewal. Confirm with the relevant city or county authority.
Reciprocity
Intra-state (local-to-local) recognition: a licence issued by one local jurisdiction is recognised by other jurisdictions within the state. There is no cross-jurisdiction list.
Wyoming Statute 16-6-1101 (effective July 1, 2024) requires all Wyoming local jurisdictions to recognise a valid plumbing licence issued by any other Wyoming local jurisdiction, provided the licence is active and the holder is in good standing with the issuing jurisdiction. The accepting jurisdiction may require documentation to verify active status and good standing but may not require retesting or charge fees for the reciprocal recognition. This is intra-state recognition only — it applies between Wyoming local jurisdictions and does not require any Wyoming jurisdiction to recognise licences from other states. Out-of-state reciprocity, if available, is determined independently by each local jurisdiction.
Bond & Insurance
Bond: Requirements vary by local jurisdiction. See notes below. No statewide bond requirement exists. Individual local jurisdictions may require a contractor bond as part of their local plumbing licensing conditions. Bond amounts where required vary by jurisdiction.
Insurance: Requirements vary by local jurisdiction. See notes below. No statewide insurance requirement exists. Individual local jurisdictions may require liability insurance and/or workers' compensation coverage as part of their local plumbing licensing conditions.

How Wyoming plumbing licensing works
Plumbing licensing requirements are administered locally in Wyoming, so credential types, examinations, fees, renewal requirements and other conditions can vary by jurisdiction.
Intra-state reciprocity
Wyoming Statute 16-6-1101, effective July 1, 2024, requires all Wyoming local jurisdictions to recognise a valid plumbing licence issued by any other Wyoming local jurisdiction, provided:
- The licence is currently active
- The holder is in good standing with the issuing jurisdiction
The accepting jurisdiction may ask for documentation confirming active status and good standing but may not require retesting or charge fees for the reciprocal recognition. The accepting jurisdiction is also not required to recognise the licence for work types not covered by the original licence.
This statute applies within Wyoming only. It does not require Wyoming jurisdictions to recognise licences issued in other states. Out-of-state reciprocity, if available at all, is determined independently by each Wyoming local jurisdiction.
What this means for homeowners and plumbers
For homeowners hiring a plumber in Wyoming, the relevant question is whether the plumber holds a valid licence issued by the local jurisdiction where the work is being performed, or a recognised licence from another Wyoming jurisdiction. Because there is no statewide registry, verifying a plumber's credentials requires contacting the local city or county building department directly.
For plumbers working in Wyoming, licensing requirements depend entirely on where the work is performed. A plumber intending to work across multiple Wyoming jurisdictions should contact each relevant local authority and confirm whether their existing licence qualifies for recognition under W.S. 16-6-1101.
In rural and unincorporated areas, requirements may differ further — some smaller jurisdictions have minimal or no formal plumbing licence requirement. Confirm with the relevant county authority.
Local authority contacts
Because plumbing licensing is local in Wyoming, there is no single point of contact at the state level. For plumbing licence requirements in Wyoming's major cities:
- Cheyenne — contact the City of Cheyenne Contractor Licensing Board, which administers local plumbing licences including Master Plumber, Journeyman Plumber, and Apprentice credentials
- Casper — contact the City of Casper Community Development Department
- Laramie, Gillette, Sheridan, Jackson — contact the relevant city building or licensing department
For work in unincorporated areas, contact the relevant county government.
