Handyman License Requirements in Port Huron, MI

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed May 2026

In Michigan, there is no single “general contractor license,” but residential maintenance/repair and remodeling work is regulated through the State’s Residential Builder and Maintenance & Alteration Contractor (M&A) licensing system. A handyman can often work without the state builder/M&A license only when the job stays under Michigan’s small-job threshold and does not include licensed trades (electrical/plumbing/HVAC) or require permits beyond what an owner/permit holder can legally pull.

⚠️ What Requires a Contractor License

The following work requires a state-issued contractor license in MI. Performing this work without a license exposes you to fines, stop-work orders, and civil liability:

• Residential building/remodeling/repair work over $600 total (labor + materials) typically requires a Michigan Maintenance & Alteration Contractor license (or Residential Builder license depending on the scope)
• Electrical work (new circuits, outlets/switches, panel work, running cable, most troubleshooting/repairs) requires appropriate Michigan electrical licensure and permits/inspections
• Plumbing work beyond very limited fixture swap scenarios—especially any piping changes, drainage/vent work, water heater installation in many jurisdictions—generally requires a licensed plumber and permits
• Mechanical/HVAC work (furnace/AC install, ductwork changes, refrigerant lines, gas piping) generally requires Michigan mechanical licensing and permits; refrigerant handling also requires EPA 608 certification
• Structural work (load-bearing walls, framing changes, decks/porches structural repair, roof structure) typically triggers building permits and often requires licensed contractor involvement
• Roof replacement and major exterior envelope work often triggers permits and may be treated as contractor-level work requiring the state builder/M&A license depending on contract value and scope
• Any work requiring the contractor to pull permits: many building departments require the permit applicant to hold the appropriate state license for the scope (builder/M&A or trade license)

State Contractor Licensing Law (MI)

This threshold does NOT allow you to perform electrical work (beyond very limited homeowner/maintenance exceptions), plumbing, mechanical/HVAC, or other regulated trades without the proper trade license. Even if under $600, local building permits may still be required depending on scope (e.g., structural work, water heater replacement, furnace work).

County Requirements — St. Clair County

Business license: Not required at the county level.

Special Jurisdictions & Zones

The following special jurisdictions may have separate licensing requirements:

• Port Huron Historic Districts (local historic districts administered by the City) — If you bid exterior work near downtown/older neighborhoods, ask the City whether the property is within a local historic district and whether a Certificate of Appropriateness is required.

City Business License — Port Huron

Required. City business registration / certificate of occupancy / contractor registration (depending on activity and location)

Permit vs. Contractor License — The Legal Difference

A license is your legal authority to offer/contract for and perform regulated construction work (state builder/M&A or trade licenses). A permit is job-specific approval from the local building department to perform work at a particular address, usually followed by inspections. Even if you are exempt from state licensing under the small-job threshold, you may still need permits for certain work, and many permits can only be pulled by the property owner or a properly licensed contractor.

Business Entity Registration (MI)

To operate legally you must register your business. LLC filing fee in MI: $50 (one-time).

Compliance Notes for Port Huron, Michigan

• Insurance: Even when not legally mandated statewide for handymen, general liability insurance is commonly required by customers, property managers, and for city permit/registration processes; $1,000,000 per occurrence is a common market baseline for small contractors.
• Advertising/contracting: If you take jobs that require an M&A/Residential Builder license, you should ensure your license is active before advertising/contracting and that contract paperwork meets Michigan requirements (change orders, scope, payment terms).
• Permits: Many code issues arise because unlicensed individuals perform trade work or start work without permits; this can lead to stop-work orders, failed inspections, and expensive tear-outs.
• Employees: If you hire helpers/employees, you may need Michigan Unemployment Insurance and workers’ compensation coverage depending on size and classification; confirm with Michigan UIA and DIFS/insurance provider.

Legal Registration Steps for Port Huron

Follow these steps to operate legally as a handyman in Port Huron, Michigan:

1. Step 1: Form your business entity (LLC) with Michigan LARA (Articles of Organization $50) and file your annual statement each year ($25).
2. Step 2: If you will exceed the $600 threshold or do ongoing remodeling/repairs, pursue the Michigan Maintenance & Alteration Contractor (M&A) license (and/or Residential Builder depending on scope) through LARA/BCC; budget roughly $195–$215 for the state license plus exam fees.
3. Step 3: Contact the City of Port Huron (Clerk + Building/Planning) to confirm whether you must register as a contractor to pull permits and whether a home-occupation/zoning approval is required for your business address.
4. Step 4: Buy general liability insurance and keep proof available for customers and for any city permit/registration process.
5. Step 5: Do not perform electrical/plumbing/HVAC unless you (or your subcontractor) holds the proper Michigan trade license and permits are pulled/inspections completed.
