Spray Foam Insulation License Requirements in North Dakota
Licensing is based purely on contract dollar value, not trade type — insulation is not called out separately.
License Requirement
Licensing body: North Dakota Secretary of State
North Dakota's general contractor licensing is administered by the Secretary of State using four classes (A, B, C, D) based purely on contract dollar value rather than trade type — insulation is not called out as a separate classification. A license is required once a job's cost, value, or price exceeds $4,000. Class thresholds run from Class D (up to $100,000) through Class A (over $500,000).
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
North Dakota requires a certificate of liability insurance (naming the Secretary of State) and proof of workers' compensation coverage (a WSI payment certificate or letter of good standing) — our research did not find a separate surety bond requirement.
