CGC vs CBC: What's the Difference Between General and Building Contractors in Florida?

Two Licenses, Two Scopes — Why It Matters for Your Project

When you search for a contractor in Florida, you'll quickly encounter two license types that sound almost identical: CGC (Certified General Contractor) and CBC (Certified Building Contractor). Both are issued by the Florida Construction Industry Licensing Board (CILB) and both require passing a rigorous state examination — yet they carry meaningfully different scopes of authority. Hiring the wrong type for your project isn't just a technicality; it can affect permit approvals, insurance coverage, and your legal recourse if something goes wrong.

This guide explains exactly what each license covers, gives you real-world examples of when each is appropriate, and shows you how to verify the right license before you sign anything.

What Is a CGC (Certified General Contractor)?

Under Florida Statute §489.105(3)(a), a Certified General Contractor is authorized to perform or supervise construction, remodeling, repair, or improvement of any building or structure — of any type, any size, any height. There is no restriction based on building height, use type, or project value.

CGC Scope of Work

Residential homes — single-family, multi-family, condominiums
Commercial buildings — office, retail, industrial, medical
High-rise construction (no height limit)
Public buildings — schools, hospitals, government facilities
Complex structural projects, additions, and renovations of any scale
Demolition of any structure

A CGC license represents the broadest construction authority available in Florida's contractor licensing system. A contractor holding CGC1234567 can legally bid on and manage a 40-story Miami condo tower or a single-family home addition in Ocala. The license does not discriminate by project type or scale.

What CGC Does NOT Include

A general contractor license alone does not authorize specialty trade work. A CGC cannot personally perform electrical, plumbing, HVAC, roofing, or pool work without also holding the relevant specialty license. On any significant project, a CGC hires and supervises licensed sub-contractors for these trades — which is exactly how the system is designed to work.

What Is a CBC (Certified Building Contractor)?

A Certified Building Contractor, defined under §489.105(3)(b), has a more specific scope: commercial and residential buildings that are three stories or less in height, plus accessory structures. A CBC can also perform remodeling, repair, or improvement of any size building as long as the work does not affect the structural members of the building.

CBC Scope of Work

Single-family homes — no restrictions within scope
Duplexes, townhomes, and small multi-family buildings
Commercial buildings up to 3 stories (offices, retail, restaurants)
Remodeling and repair of any building, provided structural members are not affected
Residential additions and renovations within the height limit

For the vast majority of residential homeowners in Florida, a CBC contractor has more than adequate authority. Most home renovations, additions, and new custom home construction fall well within CBC scope.

When CBC Scope Is NOT Enough

A CBC license is insufficient for:

Any building over 3 stories (a 4-story apartment building requires CGC)
Complex commercial or industrial facilities (manufacturing plants, hospitals, large warehouses)
High-rise residential or mixed-use development

Attempting to obtain a permit for out-of-scope work on a CBC license is a violation of Florida Statute §489.129 and can result in license disciplinary action — and leaves you, the owner, with a problematic project.

How Are These Licenses Issued?

Both the CGC and CBC licenses are issued by the Florida Construction Industry Licensing Board (CILB), a division of the Florida Department of Business and Professional Regulation (DBPR). The path to obtaining either license involves:

Experience requirement: At least 4 years of verifiable construction experience, with at least 1 year in a supervisory role (or qualifying education)
State licensing exam: Both CGC and CBC applicants must pass a Florida contractor examination covering business and finance, project management, and trade knowledge. The CGC exam is generally broader and more comprehensive.
Financial responsibility: Demonstrated financial solvency — the CILB reviews credit history and financial statements
Insurance: Proof of general liability and workers' compensation insurance (or valid exemption)
Background check: Criminal background review

Both licenses require continuing education and biennial renewal through the DBPR. Contractors must complete 14 hours of continuing education every two years to keep their license current and active.

Real-World Examples: CGC vs CBC in Florida

Scenario 1: New Custom Home in Naples — Either Works

A homeowner is building a 4,500 sq ft custom single-family home with a budget of $1.2 million. A single-family home is one story or two (rarely three), so this is well within CBC scope regardless of budget. A CGC is equally authorized and may be preferred for high-value custom homes where structural complexity is greater.

Scenario 2: 6-Story Miami Condo Tower — CGC Required

A developer is building a 6-story mixed-use condominium in Brickell. A CBC is not authorized for this project. The general contractor must hold a CGC license. Any CBC who attempted to pull permits on this building would be in violation of §489.129.

Scenario 3: Kitchen Remodel in Orlando — Either Works

A homeowner wants a full kitchen renovation with structural wall removal, electrical, and plumbing work at a total budget of $85,000. Both a CGC and CBC are fully authorized for this project. Focus instead on the contractor's experience, references, and verified license status.

Scenario 4: Office Build-Out in Tampa, 2nd Floor — Either Works

A dental practice wants to build out a 2,500 sq ft second-floor office suite in a medical building. Total cost: $350,000. This is within CBC scope — the building is two stories, which is within the three-story limit for new construction, and the work does not affect structural members. A CGC is also authorized. Either can legally do this work.

How to Verify CGC vs CBC License Status

Before hiring any contractor, confirm their exact license type and that it is Current, Active. Use the FloridaContractorCheck search tool to instantly look up any contractor's license, view their license type (CGC or CBC), check for disciplinary actions, and confirm their insurance is on file.

Florida license numbers for these types follow the format:

CGC123456 — Certified General Contractor
CBC123456 — Certified Building Contractor

Also available are Registered versions of both licenses (RGC and RBC), which are county-issued rather than state-certified and have jurisdiction limited to the issuing county. State-certified CGC and CBC licenses are valid statewide.

Which Should You Hire?

For most Florida homeowners, the difference is academic — both license types have the authority to handle typical residential construction and renovation. Focus on:

License status is Current, Active (no expired, suspended, or revoked status)
Clean or explainable disciplinary history
Adequate general liability and workers' compensation insurance
Relevant experience with your project type
Strong local references

For commercial projects exceeding 3 stories, require a CGC specifically. For everything else, use the license search to verify credentials and let the contractor's track record guide your decision.
