Michigan Contractor Authority - State Contractor Authority Reference

Michigan's contractor licensing framework operates under a segmented regulatory structure administered by the Michigan Department of Licensing and Regulatory Affairs (LARA), which oversees distinct license classifications for residential builders, maintenance and alteration contractors, electrical contractors, mechanical contractors, and plumbing contractors. This reference covers the scope of Michigan's contractor authority, how licensing and enforcement mechanisms function, the scenarios in which contractors and project owners most frequently encounter regulatory boundaries, and the structural distinctions that define different contractor categories in the state. The National Contractor Authority network maintains this reference as part of a broader system of state-level contractor authority documentation spanning the full United States.

Definition and Scope

Michigan contractor authority refers to the legal and regulatory power vested in the state — primarily through LARA's Bureau of Construction Codes (Michigan LARA Bureau of Construction Codes) — to license, regulate, discipline, and where necessary revoke the operating authority of contractors performing construction, remodeling, electrical, plumbing, mechanical, and related trade work within state boundaries.

Michigan's licensing statute, the Occupational Code (MCL 339), establishes the foundational requirement that contractors performing residential construction or maintenance and alteration work above a defined threshold obtain a license from the state. Licensing is not optional for covered work categories: operating without a required license exposes contractors to civil penalties and subjects completed work to stop-work orders.

The state's regulatory scope divides into 5 primary contractor license classifications:

1. Residential Builder — authorizes construction and sale of residential structures, including contracting for remodeling, repair, and improvement.
2. Maintenance and Alteration Contractor — covers specialty trades including masonry, tile, painting, insulation, roofing, siding, glazing, and lathing.
3. Electrical Contractor — administered separately under the Electrical Administrative Act (MCL 338.881).
4. Mechanical Contractor — covers HVAC, refrigeration, and related systems under the Skilled Trades Regulation Act.
5. Plumbing Contractor — governed by the Plumbing Act of 2002 (MCL 338.3511), requiring master plumber licensure for firm-level contracting authority.

For practitioners and researchers comparing Michigan's framework to neighboring states, Ohio Contractor Authority documents Ohio's licensing and enforcement structure, which uses a county-level registration layer absent from Michigan's system. Indiana Contractor Authority covers Indiana's framework, where contractor licensing requirements are significantly less comprehensive at the state level than Michigan's.

The Michigan Contractor Authority reference site provides current classification detail, examination requirements, and bonding thresholds specific to Michigan's LARA licensing divisions.

How It Works

Michigan's licensing mechanism requires applicants to demonstrate trade experience, pass a written examination, carry liability insurance at LARA-specified minimums, and — for residential builders — post a builder's bond. The standard residential builder bond requirement is set at $25,000 (Michigan LARA Residential Builder Licensing).

Once licensed, contractors operating in Michigan must display their license number on all contracts, advertisements, and permit applications. Local municipalities issue building permits; inspectors verify that permit applicants hold valid state licenses for covered trade categories. LARA maintains a public license verification database that property owners, general contractors, and project owners use to confirm active license status before executing contracts.

Enforcement actions — including civil fines, license suspension, and revocation — are administered through LARA's complaint and investigation process. Disciplinary records are publicly accessible, a structural feature that distinguishes Michigan's system from states with more limited public disclosure practices.

The how it works reference section of this network describes the general mechanisms by which state contractor authority operates across jurisdictions, providing a basis for comparing Michigan's procedures against other state models.

For commercial project contexts, Illinois Commercial Contractor Authority documents how Illinois structures its commercial contractor licensing — a useful contrast given Michigan's distinct separation between residential and trade-specific licensing categories. Pennsylvania Contractor Authority covers Pennsylvania's Home Improvement Contractor registration system, which differs structurally from Michigan's LARA examination-and-bond model.

Common Scenarios

Michigan contractor authority intersects with real-world activity across 4 recurring scenario types:

Scenario 1: Residential Remodeling Without License
A property owner contracts with an unlicensed individual for a kitchen remodel exceeding $600. Michigan's Occupational Code places the liability exposure on both parties: the contractor faces civil penalties, and the owner may lose statutory protections under the Michigan Builder's Trust Fund Act (MCL 570.151), which requires contractors to apply client payments to the project before retaining profit.

Scenario 2: Subcontractor Chain Verification
General contractors on Michigan projects are responsible for confirming that subcontractors hold appropriate state licenses for their respective trades. A licensed residential builder engaging an unlicensed electrical subcontractor may face regulatory exposure even if the builder's own license is current.

Scenario 3: Out-of-State Contractor Entry
Contractors licensed in other states seeking to work in Michigan must obtain Michigan-specific licenses; Michigan does not participate in a universal reciprocity agreement. Contractors from states such as Tennessee — documented at Tennessee Contractor Authority — or Georgia — covered at Georgia Contractor Authority — must complete Michigan's full application process.

Scenario 4: Commercial vs. Residential Scope
Michigan's residential licensing categories do not automatically extend authority to commercial construction. Commercial projects above certain occupancy and use thresholds require contractor qualifications that align with local municipality requirements and Michigan's Construction Code Act rather than the Occupational Code's residential provisions.

California Contractor Authority and California Commercial Contractor Authority document California's dual-track structure — a comparable model where residential and commercial contractor authority are separately delineated with distinct examination and bonding requirements.

Decision Boundaries

Understanding where Michigan contractor authority begins and ends requires clarity on 3 structural distinctions:

Residential vs. Commercial Authority

Michigan's residential builder and maintenance and alteration licenses govern work on 1-to-3 family dwellings and related structures. Construction on commercial buildings, multi-family residential above 3 units, and institutional structures falls under different code authorities, primarily enforced at the local level through Michigan's Construction Code Act (MCL 125.1501 et seq.) and administered by local building departments rather than LARA's residential licensing bureau.

State License vs. Local Permit

A state license from LARA authorizes a contractor to operate legally in Michigan. A local building permit authorizes a specific project at a specific address. Both are required for covered work; neither substitutes for the other. Detroit, Grand Rapids, and Lansing each maintain independent permit offices with project-specific requirements layered above state licensing standards.

License-Required vs. Exemption Categories

Michigan law exempts certain work categories from the residential builder license requirement — including owners performing work on their own property, certain agricultural structures, and projects below the statutory threshold. However, trade licenses (electrical, plumbing, mechanical) carry separate exemption rules that are narrower in scope; a homeowner exemption for general construction does not extend to licensed-trade installations.

For comparison, Texas Contractor Authority covers Texas's approach, where general contractor licensing is not administered at the state level but trade licenses are — an inversion of Michigan's framework. Washington Contractor Authority documents Washington's unified contractor registration system, which applies across trade categories under a single registration framework administered by the Department of Labor & Industries.
