Hiring a Contractor in Michigan: What Homeowners Need to Know

Michigan's contractor licensing framework establishes specific legal requirements that govern who may perform residential construction and renovation work within the state. Homeowners engaging contractors for projects ranging from roof replacement to full additions must navigate licensing verification, insurance confirmation, permit obligations, and contract requirements — all enforced through state and local authorities. Understanding this landscape protects homeowners from financial loss, construction defects, and legal liability tied to unlicensed work.

Definition and scope

A "contractor" in Michigan is not a single uniform category. The Michigan Department of Licensing and Regulatory Affairs (LARA) administers distinct license types based on trade and project scope. The primary classifications relevant to residential projects include:

  1. Residential Builder — Licensed under the Michigan Occupational Code (MCL 339.2401 et seq.) to construct, alter, repair, or improve residential structures. This license covers the broadest scope of home construction activity.
  2. Residential Maintenance and Alteration Contractor (M&A) — A more limited license covering specific trades such as masonry, electrical, plumbing, or HVAC within residential settings.
  3. Electrical Contractor — Separately licensed under the Michigan Electrical Administrative Act (MCL 338.881 et seq.) through LARA's Bureau of Construction Codes.
  4. Plumbing Contractor — Licensed under the Michigan Public Health Code and regulated through the Bureau of Construction Codes.
  5. HVAC Contractor — Regulated under Michigan's Mechanical Rules and requiring separate licensure for mechanical system installation and service.

The Michigan Residential Builder License page details examination and experience requirements for that specific credential. For electrical work, requirements are covered at Michigan Electrical Contractor Requirements, and plumbing licensing standards are addressed at Michigan Plumbing Contractor Licensing.

Scope and coverage limitations: This page addresses contractor engagement under Michigan state law and applies to projects within Michigan's jurisdiction. Federal contracting rules, tribal land construction regulations, and commercial contracting under separate state frameworks are not covered here. Projects crossing state lines or involving federally funded housing programs operate under distinct regulatory frameworks not described on this page.

How it works

Homeowners initiating a construction or renovation project in Michigan must confirm several things before work begins.

License verification is the first step. LARA maintains a publicly searchable license database where any residential builder or M&A contractor license can be confirmed. An unlicensed contractor performing work requiring licensure violates the Michigan Occupational Code and exposes the homeowner to potential liability for unpermitted work. The distinction between Michigan Licensed vs Unlicensed Contractors carries significant legal consequences, including difficulty recovering damages through civil action.

Insurance and bonding must be confirmed independently. Michigan law requires residential builders to carry general liability insurance, but the minimum thresholds and verification process are detailed separately at Michigan Contractor Insurance and Bonding. Workers' compensation coverage is a parallel obligation addressed at Michigan Contractor Workers Compensation — homeowners who hire contractors without this coverage may face liability if a worker is injured on their property.

Permits are required for most structural, electrical, plumbing, and mechanical work under the Michigan Building Code administered through local building departments. The Michigan Contractor Permit Requirements page covers which project types trigger permit obligations. A licensed contractor is generally responsible for pulling required permits; homeowners who allow work to proceed without permits risk complications when selling the property or filing insurance claims.

Written contracts are a legal requirement for residential construction contracts exceeding $600 in Michigan under MCL 339.2412. Required elements include project description, start and completion dates, total price, and payment schedule. Full contract requirements are detailed at Michigan Contractor Contract Requirements.

Common scenarios

Roof replacement — One of the most common residential projects, typically requiring a Residential Builder or qualifying M&A license. Permit requirements vary by municipality. Relevant regulatory context is available at Michigan Roofing Contractor Regulations.

Kitchen or bathroom remodel — Projects involving plumbing, electrical, and structural changes may require contractors holding multiple licenses or a general contractor coordinating licensed subcontractors. The relationship between general and subcontractors is covered at Michigan General Contractor vs Subcontractor.

HVAC system replacement — Requires a licensed HVAC contractor under Michigan's Mechanical Rules. Homeowners should verify licensing before signing any agreement; see Michigan HVAC Contractor Requirements.

Basement finishing — Typically requires electrical and potentially plumbing permits. The contractor must be appropriately licensed for each trade involved or must subcontract those elements to licensed tradespeople.

Dispute and lien situations — Contractors who complete work and are not paid may file a construction lien against the property under the Michigan Construction Lien Act (MCL 570.1101 et seq.). Homeowners facing contractor disputes or lien threats should review Michigan Contractor Lien Law and Michigan Contractor Dispute Resolution.

Decision boundaries

Homeowners face several critical decision points when engaging contractors:

Licensed vs. unlicensed: Unlicensed contractors may offer lower prices but expose homeowners to code violations, invalid permits, and unenforceable contracts. The legal and financial risks are documented at Michigan Licensed vs Unlicensed Contractors.

General contractor vs. specialty contractor: For multi-trade projects, a licensed residential builder acting as general contractor carries overall project responsibility and coordinates licensed subcontractors. Single-trade projects (electrical panel upgrade, water heater installation) may only require the relevant specialty license holder.

Permit responsibility: While contractors typically pull permits, the homeowner bears ultimate responsibility for unpermitted work on their property. Confirming permit status is not optional.

Sales tax on materials: Michigan imposes sales tax on materials used in construction. Whether that cost is passed through or absorbed in the contract price affects total project cost. The tax treatment of contractor services is addressed at Michigan Contractors and Sales Tax.
