HB 4907 — Summary (Skilled Trades Regulation Act amendment)

Status: Introduced March 13, 2025; electronically reproduced September 11, 2025.
Sponsor: Rep. David Prestin. Referred to Committee on Regulatory Reform. Companion bill: SB 756.

Main purpose

To limit the Department of Licensing and Regulatory Affairs (LARA) from adopting or enforcing rules that would prevent certain licensed boiler tradespeople from performing periodic maintenance and testing of boiler controls and safety devices, and to rescind a related Michigan Administrative Code rule (R 339.5206).

Key provisions

  • Amends section 907 of the Skilled Trades Regulation Act (2016 PA 407; MCL 339.5907).
  • Adds an explicit prohibition (new subsection (3)) preventing the department from promulgating or enforcing any rule that restricts a:
    • Class 5B boiler installer, or
    • Class IV boiler repairer from completing periodic maintenance and testing of boiler system controls and safety devices.
  • Rescinds Michigan Administrative Code rule R 339.5206 (which, among other things, currently requires that periodic maintenance and testing of boiler controls and safety devices be performed by an individual with a valid mechanical contractor license with the appropriate classification).
  • Retains LARA’s rulemaking authority generally for safe construction, installation, inspection, alteration, servicing, operation, and repair of boilers, and allows adoption of national codes/standards.

Definitions / scope (from referenced Admin. Code)

  • Class 5B boiler installer (R 339.5174): authorized to install low‑pressure boilers of any capacity/firing rate; install power boilers of any capacity/firing rate except nuclear; and install/replace nonboiler external piping.
  • Class IV boiler repairer (R 339.5175): authorized to repair or field‑erect boilers of any pressure except nuclear; and install/replace nonboiler external piping.

Who is affected

  • Primary: individuals holding class 5B installer or class IV repairer licenses (expanded explicit authorization to perform periodic maintenance/testing).
  • Secondary: mechanical contractors, building owners/operators, boiler service providers, and LARA (in terms of constrained rulemaking/enforcement).
  • Potentially affects workplace practices, contracting arrangements, and compliance with previously applicable administrative rules.

Fiscal impact

House Fiscal Agency estimates minimal to no fiscal impact on LARA. Any costs related to rescinding rules would be absorbed within existing appropriations.

Procedural/ timeline notes

  • Introduced 03/13/2025; read first time and referred to committee (Regulatory Reform) 09/11/2025 (electronic reproduction date also 09/11/2025).
  • Companion legislation (SB 756) exists in the Senate; further committee consideration and floor action will determine enactment.

Implications to consider

  • The bill narrows LARA’s discretion to limit who may perform safety checks/testing, potentially broadening who can legally conduct periodic boiler safety testing.
  • Rescinding R 339.5206 may create a regulatory gap or require administrative adjustments to implementation and enforcement practices. Stakeholders (mechanical contractors, facility managers, safety regulators) may see changes to contracting and compliance obligations.
