Michigan HVAC License Renewal

Michigan mechanical contractor licenses don't last forever. They operate on a fixed three-year (triennial) renewal cycle managed by LARA's Bureau of Construction Codes. If you let your license lapse, your contracting authority disappears — you can't pull permits, and any work you perform for compensation becomes unlicensed work under state law.

The Renewal Cycle

Your license expires at the end of its current triennial period. Renewal requires completing your continuing education hours and paying the current renewal fee through the MiPLUS portal.

Regardless of whether you receive a renewal notice, the responsibility to renew on time is entirely yours. Don't rely on email notifications — mark the date yourself and submit early enough for LARA to process the renewal before expiration.

Continuing Education Requirements

Qualifying Officers on a Michigan mechanical contractor license must complete 6 hours of approved continuing education during each three-year renewal cycle.

A few things to watch out for:

• The 6-hour requirement applies to the Qualifying Officer, not to every employee of the firm
• Don't confuse this with the 34–40 hours required for mechanical inspectors — that's a different credential with a much higher CE load
• CE courses must be approved by LARA. Not every online CE provider carries Michigan-specific approval
• Complete the hours within the renewal cycle, retain your certificates, and follow LARA's current instructions for documenting them with your renewal

CE topics typically cover Michigan Mechanical Code updates, safety standards, and trade practice developments. Approved providers include trade organizations, community colleges, and some online platforms. Course costs vary from $50 to $150 depending on the provider and format.

Renewal Costs

LARA's current fee schedule controls the renewal fee; confirm the amount in MiPLUS rather than assuming it matches the $300 initial application fee. Confirm that all classifications currently listed on your license are included in the renewal.

Add any CE course cost, which varies by provider, to the current renewal fee when budgeting.

What Happens If You Don't Renew

An expired license means you have no legal authority to contract for mechanical work or pull permits. Continuing to operate on an expired credential carries the same penalties as working without a license: misdemeanor charges, fines between $5,000 and $25,000, and the loss of mechanics lien rights on residential projects.

Reinstatement after expiration may require a late-renewal or re-application process; confirm the current requirements with LARA. Check whether your local registration must be re-registered once your state license is restored.

Strategic Timing for Adding Classifications

If you're planning to add a new classification to your license, timing matters. The state fee for adding a classification is pro-rated based on where you are in the renewal cycle — $300 in Year 1, $200 in Year 2, $100 in Year 3. Confirm the current renewal fee separately with LARA's fee schedule before making the timing decision.

The Michigan HVAC License Guide includes a renewal timeline tracker that helps you map your CE requirements, renewal deadlines, and classification expansion decisions across the triennial cycle.
