Spray Foam Insulation License Requirements in Maryland
No SPF-specific license; the statewide Home Improvement Commission (MHIC) license covers insulation work on 1–3 unit residences.
License Requirement
Licensing body: Maryland Home Improvement Commission (MHIC)
Maryland does not license insulation as its own trade. Home-improvement work on residences of one to three units — including insulation — requires an MHIC license, which functions as Maryland's general residential-contractor licensing mechanism. Commercial-only insulation work may fall outside MHIC's residential scope; confirm with MHIC directly if your work is commercial.
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
Since June 1, 2024, MHIC licensees must carry general liability insurance of at least $500,000 (older guidance cited a lower $50,000 minimum, since superseded) and demonstrate net worth or financial solvency of at least $20,000.
