Florida Building Contractor License (CBC): Scope & Requirements

A Florida building contractor license — the CBC, or certified building contractor — covers construction of commercial buildings and residential buildings up to three stories, plus remodeling, repair, or improvement of any size building that doesn’t touch structural members. It’s one of the three Division I license classes defined in Chapter 489, Florida Statutes.

The statutory scope

Florida law defines the class precisely. Fla. Stat. 489.105(3)(b):

“‘Building contractor’ means a contractor whose services are limited to construction of commercial buildings and single-dwelling or multiple-dwelling residential buildings, which do not exceed three stories in height, and accessory use structures in connection therewith or a contractor whose services are limited to remodeling, repair, or improvement of any size building if the services do not affect the structural members of the building.”

In plain terms, that’s two separate authorizations. The first covers new construction — commercial buildings and single- or multi-dwelling residential buildings, capped at three stories, plus accessory structures like garages or sheds built alongside them. The second is independent of height: a building contractor may remodel, repair, or improve a building of any size, no story limit at all, as long as the work does not affect the building’s structural members (load-bearing walls, framing, and similar structural elements).

What a building contractor can and can’t build

• New construction: commercial and residential buildings up to and including three stories, plus the accessory structures that go with them. A fourth-story or taller new building falls outside this class.
• Remodeling, repair, or improvement: any size building, no height ceiling — but only work that doesn’t affect the structural members. Once the scope of work touches structural elements, the job moves outside the building contractor’s authorized scope.

If your work is a single-family or duplex project within the residential height limits, the Florida residential contractor license may be a narrower, more relevant fit — compare the classes on Florida contractor license types compared.

Requirements to qualify

Experience

Rule 61G4-15.001 doesn’t carry a separate experience paragraph for the building class — building applicants qualify through the same general methods listed on the DBPR CILB 5-A application, Part A: for example, four years’ experience as a worker or foreman (at least one year as a foreman), or a four-year construction-related degree plus one year of experience. Unlike General, a building contractor applicant does not need the additional “one year of experience on structures at least four stories in height” condition — that condition applies only to the General classification. See the Florida GC license requirements page for the full breakdown of qualifying methods.

Financial responsibility

The financial-responsibility rule (Fla. Admin. Code R. 61G4-15.006) is the same across classes: a FICO-derived credit score of 660 or higher, or completion of a 14-hour Board-approved financial responsibility course for applicants who don’t have that score. No state surety bond is required.

State exam

Building contractor applicants sit for the same Division 1 examination as General applicants, per the DBPR Bureau of Education & Testing. The exam has three parts — Business & Finance, Contract Administration, and Project Management. See the Florida general contractor exam page for the exam structure and how to prepare.

Insurance

Per the DBPR Construction Industry FAQ, the insurance minimums are $300,000 public liability and $50,000 property damage — identical to the General classification. A building contractor carries the same minimums, not a lighter requirement; see Florida contractor insurance requirements for detail and verify current amounts with the DBPR.

Upgrading to a general license

A building contractor who has held an active license for several years has a shortcut into the General classification. The DBPR CILB 5-A, Part A, method 6 — the “Upgrade Method” — reads:

“‘Upgrade Method’. A certified residential or building contractor holding an active current license for a minimum of 4 years in the classification in which he or she is certified. If you meet this eligibility requirement you are exempted from the Employment History section of this application. You must provide your license number for verification. See Section 2(f)(iv) of Instructions for more information.”

In practice, a building contractor with at least four years of active licensure in that classification can apply for the General class without re-documenting employment history — only the license number for verification. The other requirements (financial responsibility, exam, insurance) still apply.

How it compares to a general license

The difference between Building and General is scope and height, not qualification rigor: a building contractor’s new-construction authority is limited to three stories, unlike the unlimited scope of the general classification. See Florida contractor license types compared for how all the Division I and II classes line up, and budget the process with the Florida GC license cost breakdown.

Common questions

What is a CBC license in Florida?

CBC stands for certified building contractor. It’s a Division I license class limited to construction of commercial and residential buildings up to three stories, plus remodeling, repair, or improvement of any size building that doesn’t affect structural members (Fla. Stat. 489.105(3)(b)).

Can a building contractor work on buildings taller than three stories?

Not for new construction. Fla. Stat. 489.105(3)(b) caps a building contractor’s new-construction scope at three stories. A new building taller than three stories falls outside this class and requires the General classification, which has no height limit.

Is there a size limit on a building contractor’s remodeling work?

No size limit applies. Fla. Stat. 489.105(3)(b) allows a building contractor to remodel, repair, or improve a building of any size, regardless of height, as long as the work doesn’t affect the building’s structural members. Once structural members are involved, the job moves outside this class’s scope.

Is the building contractor exam different from the general contractor exam?

No — per the DBPR Bureau of Education & Testing, it’s the same Division 1 exam structure: Business & Finance, Contract Administration, and Project Management. See the Florida general contractor exam page for details.
