SF3574 (Legislative Session 94 (2025-2026))

Local enforcement of licensed plumbers preemption

AI Generated Summary

Purpose

The bill aims to limit local governments from creating or enforcing licensing rules for plumbers beyond what the state requires. It preserves state-level licensing and oversight, while allowing local entities to regulate plumbing permits, plan approvals, and inspections as long as those local regulations don’t conflict with the state plumbing code. It also creates specific allowances for certain non-licensed activities (like water softener installations) under local standards, and it restricts local entities from imposing additional licensing requirements on those already licensed by the state.

Main Provisions

  • Local regulation authority
    • Cities, towns with 5000+ people, certain other entities (including the Metropolitan Airports Commission) may by ordinance adopt local rules for plumbing permits, approval of plans and specifications, and inspections, as long as these rules do not conflict with the state plumbing code.
  • Limits on local licensing restrictions
    • Local entities may not prohibit contractors licensed by the state from doing plumbing work, except for cities or statutory cities that, before April 21, 1933, had a local ordinance requiring plumber licensing.
    • Local entities may not require plumbing workers to post bonds or maintain public liability insurance beyond what the state requires or what is contractually required for specific projects.
    • No city or town may require a license specifically for persons performing building sewer or water service installations if they have completed the pipe laying training prescribed by the state.
  • Water softener installations (non-licensed workers)
    • A city by ordinance may set reasonable standards and permit certain non-licensed individuals to connect water softeners or water filtering equipment to private residence water systems, as long as connections meet minimum standards set by the Plumbing Board and do not require major rearrangements or alterations.
  • Prohibition on extra credentials for state-licensed plumbers
    • No political subdivision may require additional licenses, registrations, certifications, examinations, or qualifications for someone already licensed by the state to perform plumbing work.
  • Oversight and standards
    • The provisions reference the state Plumbing Board and the Commissioner of Labor and Industry for standards and enforcement related to licensing, training, and minimum requirements.

Significant Changes to Existing Law

  • Preemption of local licensing standards
    • The bill tightens control over local licensing requirements by clarifying that local governments cannot create or enforce licenses or credential requirements beyond those established by the state, with limited historical exceptions.
  • Expanded local permitting role without licensing expansion
    • Local entities retain authority to regulate permits, plan approvals, and inspections for plumbing work, but may not impose additional licensing constraints on state-licensed plumbers.
  • Introduces a narrowly defined exception for water softener installations
    • Local regulations may permit non-licensed individuals to install water softeners under defined standards, provided these installations meet minimum Plumbing Board standards and do not require altering existing piping beyond specific limits.

Potential Impacts

  • Consistency and predictability
    • State-wide licensing remains the gatekeeper for plumbing work, creating more uniform rules across the state and reducing local licensing barriers.
  • Local regulatory flexibility
    • Local governments can handle permits and inspections and set reasonable standards for certain installations (like water softeners) without needing to license every installer.
  • Industry effects
    • Licensed plumbers and plumbing businesses may face fewer local hurdles, while non-licensed workers could perform limited installations under local oversight, potentially affecting competition and consumer protections.
  • Public safety and oversight
    • By keeping minimum standards and Board oversight, the bill seeks to balance local administration with statewide safety and competency requirements.
