Key takeaways:
- A Certified General Contractor (CGC) license in Florida authorizes the broadest scope of work — commercial and residential structures of any height or occupancy.
- A Certified Building Contractor (CBC) license is restricted to commercial and residential buildings up to three stories.
- For high-end projects, the license type is the legal threshold for who can deliver the work — but regional code fluency, a disciplined process, and dedicated service are what separate qualified contractors from suitable ones.
- Verify license, insurance, and bonding through the Florida DBPR before scope is finalized.
- Understanding how a general contractor differs from a construction manager helps owners select the right delivery model for the project.
In Florida, the two general contractor licenses an owner is most likely to encounter are the Certified General Contractor (CGC) and the Certified Building Contractor (CBC). The distinction is straightforward: a CGC is authorized to build any structure the building code permits, of any height or occupancy. A CBC is restricted to commercial and residential buildings up to three stories. For a principal commissioning a high-investment project — a custom waterfront residence, a boutique hotel build-out, a luxury commercial space — that ceiling is the line between a contractor who can deliver the work and one who legally cannot.
This guide breaks down what each license authorizes, how to think about scope, and how to verify a contractor’s credentials before scope is finalized. For owners weighing contractors specifically in the Miami market, see our resource on Commercial General Contractors Miami. For a comprehensive view of how to select and engage a contractor in South Florida, our full “General Contractors” article covers the process end-to-end.
How CGC and CBC licenses differ in Florida
Both licenses are issued by the Florida Department of Business and Professional Regulation (DBPR), the state body that regulates Florida contractor license types. Both confer the legal authority to act as a contractor. The scopes are materially different.
A Certified General Contractor (CGC) is the broadest construction license Florida issues. Per Florida Statute 489.105, a CGC is authorized to construct, repair, remodel, or improve any structure — of any height, complexity, or occupancy — that the Florida Building Code permits. That includes high-rise commercial work, multi-story residential, mixed-use development, industrial facilities, and custom homes without size or elevation limits.
A Certified Building Contractor (CBC) is narrower. The same statute limits a CBC to commercial buildings and single-dwelling or multiple-dwelling residential buildings that do not exceed three stories in height, along with the accessory structures associated with them. A CBC license cannot legally execute a four-story coastal residence, a boutique hotel above three floors, or a commercial high-rise.
The practical implication for an owner is binary. A CGC can deliver any project Florida law permits. A CBC is capped at the three-story threshold. Confirm the license type before scope is finalized — not after.

What can a CGC do in Florida?
A CGC license Florida authorizes a contractor to lead any project the building code permits. In this market, CGC firms typically deliver:
- High-rise commercial developments and tenant build-outs in towers above three stories
- Large-scale residential communities and multi-family projects
- Mixed-use buildings combining residential, retail, and hospitality
- Industrial and institutional facilities
- Custom luxury residences — of any height, square footage, or programmatic complexity
For the contractor, a CGC license Florida means access to the full range of work — from signature residences to landmark commercial builds — and the legal authority to manage every phase of the project: pre-construction planning, permit submittal, plan reviewer coordination, subcontractor coordination, inspection coordination, and certificate of occupancy.
For the owner, a CGC partner brings the ability to coordinate complex subcontractor teams and specialty trades under a single chain of accountability. That matters more on a custom oceanfront residence with understory parking, impact-rated glazing, and integrated Control4 systems than it does on a single-story remodel.
A CGC’s license becomes especially valuable when paired with deep Miami-Dade, Broward, and Palm Beach experience. South Florida is not a generic build market. The work is shaped by sun, water, wind, and code — and a contractor who has not navigated FEMA elevation, NOAs, and municipal plan reviewer coordination at scale is solving each problem for the first time on the principal’s project. A CGC fluent in those realities is not.

General contractor versus construction manager — how the roles differ
Both general contractors and construction managers play roles in project delivery, but their responsibilities and legal authority are not the same, and the difference is reinforced by Florida contractor license types.
A general contractor:
- Holds a CGC or CBC license and assumes full legal responsibility for the build
- Manages every aspect of construction — subcontractor coordination, schedule of values, sequencing, change-order management, site supervision, and final walk-through through certificate of occupancy
- Operates under a single contract with the owner: one builder, one chain of accountability, one party answerable for the work
A construction manager:
- May or may not hold a contractor license; often functions as a fee-based consultant
- Advises on planning, budgeting, and constructability, but does not typically self-perform or hold the trade contracts
- Works under an arrangement where the owner holds contracts directly with each trade
For most luxury-level work, commissioning a custom residence or high-end commercial space, the general contractor model — particularly with a CGC at the helm — is the cleaner accountability path. One contract, one builder, one party responsible from contract through certificate of occupancy. The construction manager model serves well on owner-led projects with a sophisticated in-house construction team, but it is the exception, not the standard, in luxury residential and high-end commercial work.
The accountability gap closes further when the general contractor operates on a fully integrated design-build model — design, architecture, engineering, permitting, and construction under one team and one contract. That structure eliminates the coordination gaps between architect and builder that drive most schedule slippage and budget creep. In South Florida, a properly executed design-build typically delivers two to three months ahead of the regional industry average, because planning, pricing, and constructability are addressed together from day one rather than negotiated across firm boundaries.

Verifying a contractor's credentials and reputation before hiring
Before signing a contract, verify both the license and the firm’s track record. The process is direct.
Confirm the license. Search the contractor by company or individual name on the Florida DBPR license verification portal. Confirm the license type — CBC license Florida or CGC license Florida — current status, expiration, and any disciplinary history. Verify the license matches the scope of work the project requires. Confirm the firm carries valid general liability insurance and is bonded to the level the project demands.
Research the work. Ask for completed-project references at the same scope, scale, and finish level — and follow up with each reference about timeline performance, change-order history, and how problems were handled. Review documented projects on the firm’s portfolio rather than relying on aggregator reviews alone. Search DBPR and the relevant county for any complaints, litigation, or disciplinary actions filed against the contractor.
Test the process. Ask how the firm prices a project early — and whether the initial estimate is an honest, all-in number that includes permits, landscaping, pools, and finishes, or a base-build figure that will move during construction. The pace, clarity, and accuracy of pre-contract communication is the most reliable preview of how the firm will perform during the build. Confirm who the project principal will be — firm leadership, or a project manager assigned after the contract is signed.
In high-investment markets like South Florida, the right license is the threshold for serious consideration; reputation and discipline are what separate the contractors above it. Look for evidence of partnership-level communication, regional code fluency, an honest approach to budgeting, and turn-key delivery — including post-occupancy support such as smart-home commissioning and a meaningful warranty. License plus track record plus disciplined process is the standard for the firms worth interviewing.
