municipalities; counties; occupation; licensure; prohibition

SB 1670 establishes state preemption over occupational licensing for certain trades in Arizona, preventing municipalities and counties from imposing additional licensing requirements beyond the state system. It specifically prohibits local governments from requiring a "journeyman license" for workers already covered under state licensing (Title 32, Chapter 10), except for five occupations: plumbing, pipe fitting, mechanical trades, HVAC installation, and electrical/alarm system trades. The bill defines "licensure" broadly to include any training, test, or fee beyond basic state requirements, but limits local authority to only those five specified trades. This directly affects contractors and workers in those fields by standardizing licensing rules across the state.
