Holding the prime contract does not extend your license into another trade. Under Chapter 489, F.S., most trades must be subcontracted to the holder of that trade's license, and passing an inspection afterward does not cure work performed by someone not licensed to do it. The owner-builder exemption is real but narrow: it is for an owner building for their own use and occupancy, and it requires the owner to personally supervise the work.
Certified or registered — the difference decides where you may work
Florida issues two kinds of contractor credential under Chapter 489, and the distinction is geographic. A certified contractor may contract anywhere in the state without a local competency card. A registered contractor is authorized only in the local jurisdiction that issued the competency card behind the registration.
One thing registration does not do is reduce anyone's obligations. It limits geography, not duties — a registered contractor pulls permits, calls inspections and answers for the work exactly as a certified one does within the jurisdiction where the registration is good.
What a Division I license actually covers
Division I comprises the general, building and residential categories. What they share is that they contract for the structure as a whole. That is the scope: the building, its assembly, its sequencing and its completion.
What Division I is not is a superset of every trade that happens on the site. Roofing, plumbing and underground utility work are separately licensed. So are electrical and mechanical. Those licenses exist independently of yours, and your prime contract does not absorb them.
The trap that catches experienced contractors. A Certified General Contractor holding the prime contract on a new retail building still may not install the electrical service. That work goes to a licensed electrical contractor working under subcontract. And an inspector approving it afterward does not fix it — passing an inspection does not cure work performed by someone not licensed to perform it.
The one meaningful exception, and where it stops
Chapter 489 does recognize a narrow exception for Division I contractors: a general, building or residential contractor may install shingle roofing materials on a new building of its own construction. That is the whole exception, and each qualifier in it is load-bearing — shingle materials, a new building, one you are building yourself.
Plumbing, mechanical and electrical work carry no comparable exception. A residential contractor who wants its own carpentry crew to set the plumbing rough-in in a house it is building may not do it, regardless of who pulled the building permit. Neither a licensed plumber looking at the work afterward nor a local approval turns unlicensed trade work into licensed trade work.
The license qualifies a business through a person
This is the part that costs companies money, because it is a structural fact about how Florida licensing works rather than a paperwork detail.
A license qualifies a business organization only through a living qualifying agent. If the only qualifying agent resigns, the business may not engage in contracting until it qualifies another agent and notifies the Board. The individual who left keeps their own certificate — it is the business, not the person, that is suddenly without qualification, and any contract signed in the gap was signed by an entity with no authority to contract.
While a qualifier is in place, the responsibility is broad. The qualifying agent is answerable for all construction activities of the entity being qualified, including its financial matters. Not knowing a permit was pulled, or having handed the money side to a company owner, does not shift that responsibility elsewhere.
The owner-builder exemption
Florida lets an owner act as their own contractor in defined circumstances, and the exemption is widely misunderstood — usually by people hoping it is broader than it is.
The exemption is available to an owner who builds or improves a residence for the owner's own use and occupancy. That purpose is the whole point of it. Using it for a unit built to sell, for a rental, or for work on someone else's property defeats the purpose and violates the statute.
It also assumes the owner is genuinely acting as their own contractor, which means personally supervising the construction work being performed and using licensed trades for the trades. It cannot be lent to a contractor who would rather not pull the permit in their own name, and its use on commercial work is limited in value rather than open-ended.
The practical version for a homeowner: if someone offers to do your job "under your owner-builder permit," they are asking you to take on responsibility for supervising work you are not going to supervise, on a permit that exists on the assumption that you will. See how the owner-builder permit works for the detail.
What happens when the rule is ignored
The consequences show up in three separate places, and they do not cancel each other out. There is the licensing consequence, which runs through the DBPR and the CILB. There is the permitting consequence, where a building official can require concealed work to be uncovered and exposed so it can be inspected, at the contractor's expense. And there is the civil consequence, which is the one owners feel — defective work performed by an unlicensed trade is still defective work, and Florida's construction defect process under Chapter 558 applies to it.
None of this is cured retroactively by an approval. That principle runs through the whole scheme: building without a permit and using an unlicensed trade both leave a defect in the record that a later inspection does not erase.
Where this sits on the exam
Scope questions are the reliable point-losers in the Licensing, Permits and Inspections area, because on a real job the answer is usually "we sub that out anyway" and the exam wants to know why — which statute, which exception, which responsibility. Our bank covers the area with questions written in the form the exam uses.
