Spray Foam Insulation License Requirements in Michigan
Insulation is a named trade code ("G") under the Residential Maintenance & Alteration Contractor license, with its own exam.
License Requirement
Licensing body: Michigan LARA, Bureau of Construction Codes
Michigan is one of the more explicit states on this list: insulation work is a named trade/craft (code "G") under the Residential Maintenance & Alteration (M&A) Contractor license issued by LARA's Bureau of Construction Codes, with a dedicated 100-question insulation trade exam (72 correct required to pass). A broader Residential Builder license also exists for general residential contracting, but the narrower M&A license with the insulation code is the more direct fit for SPF-only contractors.
SPFA Certification Relevance
SPFA (Spray Polyurethane Foam Alliance) certification is not a legal requirement here — no state licensing board makes it a condition of licensure. It remains a voluntary industry credential that some manufacturers require for warranty coverage and that SPFA's Professional Certification Program (PCP) references in federal Unified Facilities Guide Specifications (UFGS) for government contracts.
Bonding & Insurance Facts
LARA licensing requires proof of financial responsibility/insurance as part of the application, though the specific dollar figure was not independently confirmed in our research — check LARA's current licensing packet for the exact requirement.
