CONTRACTOR LICENSING GUIDE
What Are the Most Common Contractor License Classifications?
Contractor licenses aren’t one-size-fits-all. Here’s what the most common classifications cover and where they apply.
How License Classifications Work
Contractor license classifications define the scope of work a licensed contractor is authorized to perform. A classification system exists to ensure that a contractor licensed for residential remodeling is not taking on large commercial high-rise projects without the appropriate credentials.
The most common classification types across licensing states:
General Contractor (GC) / Building Contractor: The broadest classification, typically covering new construction, renovation, and repair of structures. States split this into commercial and residential tiers in many cases.
Specialty Trades: Separate license classifications for electrical, plumbing, HVAC/mechanical, roofing, fire suppression, and other trades. Most states require specialty licenses for these trades regardless of whether they require GC licensing.
Residential vs. Commercial: Many states split GC licensing by project type. Florida has Certified General Contractor (commercial and residential) and Certified Building Contractor (primarily residential). Working on commercial projects under a residential-only classification is a licensing violation.
Unlimited vs. Limited Value: Some states classify by project dollar value. Tennessee requires licensing for projects over $25,000. Within licensing states, some classifications are limited to projects under a dollar threshold.

What’s the difference between a GC license and a building contractor license?
Definitions vary by state. In Florida, a Certified Building Contractor is slightly more restricted than a Certified General Contractor — primarily residential. Always check your specific state’s scope of work for each classification.
Can I hold multiple license classifications?
Yes in most states. You apply for each classification separately, pay separate fees, and maintain separate insurance and CE requirements for each.
What if I take on work outside my classification?
That’s a licensing violation — grounds for disciplinary action, suspension, and loss of ability to enforce contracts for that work.
