AZ HB2321

Establishes strict criteria that cities, towns, counties, and state agencies must meet before regulating occupations, professions, activities, or property use, including requirements that regulations protect public health/safety (not economic interests) and use the least restrictive means available.

Requires local governments and agencies to hold public hearings and make specific findings that proposed regulations meet statutory criteria before enactment.

Mandates that all existing regulations in place when the law takes effect must be repealed within 5 years unless the regulating entity formally reauthorizes them through the criteria process.

Provides a legal defense for anyone subject to civil or criminal enforcement of a regulation that violates these requirements, with courts able to award attorney fees and costs to the prevailing party.

Requires any new regulatory requirement established by the legislature to include a specific expiration date no more than 5 years after the law takes effect.
