Insulation falls under the "Nonstructural Renovation" specialty category, which now requires a technical exam.
License Requirement
Licensing body: South Carolina Department of Labor, Licensing and Regulation (LLR), Contractor's Licensing Board
South Carolina groups insulation under a "Nonstructural Renovation" specialty classification (which also covers fireproofing, lining, painting, and waterproofing) within LLR's residential specialty categories. Effective January 1, 2025, this classification requires passing a technical exam through PSI. General/mechanical contractor licensure is required above $10,000 for commercial work (raised from $5,000 by a 2023 amendment); residential specialty and builder thresholds were reported around $500 and $5,000 respectively in secondary sources.
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.
