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. Trade Safe guides contractors through what a license actually requires because the bond or policy on file has to stay current with the license, without leaving contractors to sort state rules out alone.
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.
