Michigan Specialty Contractor Licenses: Complete Reference

Michigan's specialty contractor licensing framework governs tradespeople who perform defined categories of construction work — electrical, plumbing, mechanical, and related disciplines — under authority distinct from the residential builder or commercial general contractor license. These licenses are issued and enforced by the Michigan Department of Licensing and Regulatory Affairs (LARA), with some trade categories falling under the Michigan Bureau of Construction Codes. Understanding which license category applies to a given scope of work is essential for contractors, project owners, and compliance officers navigating Michigan's multilayered construction regulatory environment.

Definition and scope

Specialty contractor licenses in Michigan cover trade-specific work that requires demonstrated technical competency, trade examination passage, and in most cases, proof of insurance and bonding. Unlike the Michigan Residential Builder License, which authorizes broad construction activity on one-to-two family dwellings, specialty licenses are narrowly scoped to defined trades.

The principal specialty license categories regulated in Michigan include:

  1. Electrical contractors — governed under the Michigan Electrical Administrative Act (Act 217 of 1956), with licensing administered through LARA's Bureau of Professional Licensing
  2. Plumbing contractors — regulated under the Michigan Plumbing Act (Act 733 of 2002), requiring licensure at both the master plumber and plumbing contractor entity level
  3. Mechanical/HVAC contractors — covered under the Michigan Mechanical Code and requiring a licensed mechanical contractor registration
  4. Boiler contractors — regulated under the Boiler Act and overseen by the Michigan Department of Labor and Economic Opportunity (LEO)
  5. Elevator contractors — subject to the Elevator Safety Board under LEO
  6. Residential maintenance and alteration contractors — a sub-tier license category for limited-scope work under the Michigan Occupational Code

Each trade license operates under a separate statutory authority, meaning requirements, exam bodies, renewal schedules, and disciplinary procedures differ by trade. A contractor holding a master electrician credential does not thereby acquire authorization to perform plumbing work, and vice versa.

Scope boundary: This page covers specialty contractor license categories regulated under Michigan state law. It does not address federal contractor licensing, tribal jurisdiction requirements, municipal overlay licensing that individual cities may impose beyond state minimums, or licensing requirements in bordering states. For the broader licensing landscape, the Michigan Contractor Licensing Requirements reference covers foundational requirements across all license types.

How it works

The pathway to a Michigan specialty contractor license follows a structured sequence that varies by trade but shares common elements:

  1. Qualifying experience — Most trades require documented field experience at the journeyman level before a master or contractor license is attainable. Electrical candidates typically must accumulate 8,000 hours of experience under a licensed master electrician before sitting for the master examination (LARA Bureau of Professional Licensing).
  2. Trade examination — Specialty licenses require passage of a proctored trade exam. Electrical and plumbing exams are administered through approved third-party testing providers under LARA authority. Exam preparation resources and approved providers are listed through Michigan Contractor Exam Preparation.
  3. Entity registration — Holding an individual master credential does not automatically authorize contracting work. A separate business entity registration as a licensed contractor (e.g., electrical contractor license, plumbing contractor license) is required before accepting contracts. See Michigan Electrical Contractor Requirements and Michigan Plumbing Contractor Licensing for trade-specific details.
  4. Insurance and bonding — Most specialty contractor registrations require proof of general liability insurance and, where applicable, a surety bond at registration and renewal. Full coverage requirements are detailed in Michigan Contractor Insurance and Bonding.
  5. Permit and inspection compliance — Licensed specialty contractors must pull permits for most regulated work. Permit obligations by trade are covered in Michigan Contractor Permit Requirements.
  6. Continuing education and renewal — Specialty licenses carry defined renewal cycles, typically biennial, and several trades require continuing education units (CEUs) for renewal. Details on CEU obligations appear in Michigan Contractor Continuing Education and renewal procedures in Michigan Contractor License Renewal.

Common scenarios

Scenario 1 — Electrical subcontractor on a residential project: A general residential builder hires an electrical subcontractor. The subcontractor must hold a valid Michigan electrical contractor license, not merely an individual journeyman card. The master electrician of record must be affiliated with the contracting entity. Failure to verify this distinction is a documented source of Michigan Contractor Disciplinary Actions.

Scenario 2 — HVAC replacement and installation: A mechanical contractor performing forced-air system installation in a new residential build must hold the appropriate mechanical contractor registration. If refrigerant handling is involved, federal EPA Section 608 certification is required in addition to the Michigan state credential. See Michigan HVAC Contractor Requirements for the full credential stack.

Scenario 3 — Roofing contractor classification: Roofing does not carry a distinct state specialty license in Michigan the way electrical and plumbing do. Roofing work on residential structures falls under the residential builder or residential maintenance and alteration contractor license. Commercial roofing falls under the Michigan Commercial Contractor Requirements framework. Michigan Roofing Contractor Regulations describes the classification boundaries in detail.

Scenario 4 — Unlicensed work complaints: Property owners who discover that specialty work was performed without proper licensure have recourse through LARA's complaint process. The distinction between licensed and unlicensed contractors in enforcement contexts is covered in Michigan Licensed vs Unlicensed Contractors.

Decision boundaries

Specialty license vs. residential builder license: A residential builder license authorizes the supervision of an entire one-to-two family dwelling construction project but does not authorize the licensee to personally perform electrical, plumbing, or mechanical work without the corresponding specialty credential. These are parallel, non-substitutable licenses.

Master credential vs. contractor registration: The master credential certifies individual competency. The contractor registration authorizes business operations. Both are required concurrently for lawful specialty contracting. Operating only under a master credential without entity registration violates the Michigan Occupational Code.

State license vs. local requirements: Michigan's specialty contractor licenses set the minimum floor. Individual municipalities — Detroit, Grand Rapids, Lansing, and others — may impose additional registration, permit, or bond requirements. The Michigan Bureau of Construction Codes publishes guidance on state-local interaction. The michigancontractorauthority.com reference network provides context on how state and local requirements intersect across trade categories.

Workers' compensation compliance: Specialty contractors employing workers are subject to Michigan workers' compensation requirements independent of their trade license. This obligation is covered in Michigan Contractor Workers Compensation.

The Michigan General Contractor vs Subcontractor reference clarifies how specialty contractors are positioned within the project delivery hierarchy and which licensing obligations attach at each tier.
