Wyoming — plumbing code & licensing

Partially verified

Partially verified. Wyoming issues no state plumber license and has no statewide plumbing code. That rests on the current statute structure — Title 33, ch. 47 is the Dietetics Licensure Act, not the 2011 plumber bill (SF0154), and no plumber board or program appears in the Wyoming sources opened — but no official page opened states the 2011 bill's disposition in so many words.

The code

Code family	none-statewide
Edition in force	no statewide edition — adoption is local
Effective date	no statewide code — adoption and dates are local
Adopted by	None at state level - no statewide plumbing code adoption was found in the Wyoming sources opened; adoption is municipal/county
Adoption source	http://wyoleg.gov/Legislation/2011/SF0154
State amendments	Amendments are a local matter — no state-level set

Licensing

Model	Local-only in practice: Wyoming issues no state plumber license. The 2011 bill SF0154 would have created a Plumbers Licensing Act at W.S. 33-47-101 et seq. with a board of plumber examiners, but Title 33, ch. 47 in current Wyoming law is the Dietetics Licensure Act (W.S. 33-47-101 through 33-47-110); plumbing licensing is handled by municipalities
Authority	None at state level (municipal licensing, e.g. Cheyenne, Casper, Gillette)
Licensing source	http://wyoleg.gov/Legislation/2011/SF0154

Why partial: a structural absence rests on the form of the source.

Working notes

OPEN GATE: the non-implementation of the 2011 plumber-licensing bill is established negatively - the official Wyoming Dietetics Licensing Board page (dietetics.wyo.gov/rules, opened) confirms current Title 33 ch. 47 is the Dietetics Licensure Act, and no plumber board, license program, or statewide plumbing code adoption appears in the Wyoming sources opened - but no official page opened states the 2011 bill's disposition in so many words, so the row is partial. Wyoming does license electricians statewide through the State Fire Marshal; plumbing was not given the same treatment.
