What Florida's sheet metal certification actually covers, the gauge threshold that defines it, the four experience routes, the exam, the fees and the qualifier rule.
Florida certifies sheet metal contractors through the Construction Industry Licensing Board, and the certification covers sheet metal fabrication, duct work and air handling systems built from U.S. No. 10 gauge metal or lighter, statewide and without a project size limit. To apply for a Florida sheet metal contractor license you prove your eligibility through one of four experience routes, pass a two part certification exam, bind the required insurance and qualify a business organization under the statute. This guide works through the statutory scope, the gauge threshold, the experience routes, the exam structure, the board fees, the insurance floor and the qualifier rule from the statute and rule text itself.
At a glance
- Scope is defined by gauge. The category covers ferrous and nonferrous metal work of U.S. No. 10 gauge or its equivalent or lighter, and other materials used in lieu of it (F.S. 489.105(3)(d)).
- Everyone else must subcontract it. A contractor must subcontract all sheet metal work unless it holds a state certificate or registration in the trade (F.S. 489.113(3)).
- Air handling is in the scope. Setting air handling equipment, reinforcing it, balancing air handling systems and duct cleaning that requires partial disassembly all fall inside the category (F.S. 489.105(3)(d)).
- Insurance. A sheet metal contractor carries $100,000 in public liability and $25,000 in property damage coverage (rule 61G4-15.003).
- Board fees. $335 for the application and examination, $135 on scheduling, $80 for each test administered, $40 after you pass (rule 61G4-12.009).
What the license actually authorizes
The Department of Business and Professional Regulation issues the license through the Construction Industry Licensing Board. F.S. 489.105(3)(d) defines a sheet metal contractor as one whose services are unlimited in the sheet metal trade and who has the experience, knowledge and skill to manufacture, fabricate, assemble, handle, erect, install, dismantle, condition, adjust, insulate, alter, repair, service or design, where design is not reserved by other law, qualifying metal work.
Two parts of that definition carry weight. "Unlimited" means there is no project size or dollar ceiling inside the trade. The design clause means layout and system design work sits inside the license wherever other law does not reserve it to an engineer or architect. For how this category sits beside every other Florida construction license, see our Florida contractor license guide, and for the same question outside Florida, see the national contractor license pillar.
The statute names the air side of the trade explicitly. The scope includes air handling systems, the setting of air handling equipment and the reinforcement of the same, the balancing of air handling systems, and duct cleaning and equipment sanitizing that requires at least a partial disassembling of the system. That clause is the practical dividing line in duct work: cleaning that requires opening the system is contracting, and cleaning that does not is not.
The gauge threshold, in plain terms
The jurisdictional line in this category is a material thickness, not a building type. The license covers metal work of U.S. No. 10 gauge or its equivalent or lighter gauge, and other materials used in lieu of metal, including but not limited to fiberglass.
Thicker than No. 10 gauge, the work is generally structural and belongs to a different category. Lighter than No. 10 gauge, and in a material substituted for metal, the work is sheet metal contracting even when it does not look like it. Fiberglass duct board is named in the statute for exactly this reason.
Why the subcontracting rule is the business case
F.S. 489.113(3) is the sentence that creates demand for the license. A contractor must subcontract all electrical, mechanical, plumbing, roofing, sheet metal, swimming pool and air conditioning work, unless that contractor holds a state certificate or registration in the respective trade category.
A general, building or residential contractor cannot self perform sheet metal work on the strength of its own license. The statute's carve outs cover structural components and site work, certain new construction roofing by the contractor that built the structure, swimming pool structural work, main utility lines, mobile home park utility continuations, and residential solar equipment. None of them reach sheet metal.
| Who holds the work | Can self perform sheet metal | Basis |
|---|---|---|
| Certified sheet metal contractor | Yes | Holds the trade certificate |
| General or building contractor | No | F.S. 489.113(3), no carve out |
| Mechanical contractor | Only within its own scope | Separate category |
| Unlicensed company | No | Must be certified or registered |
Sheet metal, mechanical and air conditioning are three licenses
This is the single most common error in published guides on this category. Florida maintains separate Division II categories for sheet metal, mechanical, Class A air conditioning and Class B air conditioning. They overlap in the field and do not overlap on paper.
A company that fabricates and installs duct, sets and reinforces air handlers and balances systems is doing sheet metal work. A company that installs, services and repairs the refrigeration and heating equipment itself is in air conditioning or mechanical territory. Companies doing both usually hold more than one certificate, or employ more than one qualifier. If the equipment side is your business, start with the Florida HVAC license guide instead.
The four experience routes
F.S. 489.111(2) sets eligibility for licensure by examination. An applicant must be 18, be of good moral character, and satisfy one of the routes below. Most competitor pages print only the four year trade route, which quietly writes off readers who already qualify another way.
| Route | Experience | Education |
|---|---|---|
| Degree | 1 year in the category | Engineering, architecture or building construction |
| Trade | 4 years, at least 1 as a foreman | None |
| Mixed A | 1 year as a foreman | 3 years of accredited college credits |
| Mixed B | 1 year skilled plus 1 year foreman | 2 years of accredited college credits |
A third mixed combination counts 2 years as a skilled worker, 1 year as a foreman and 1 year of accredited college credits. The statute resolves a question that stalls applicants for years: all junior college and community college level courses are considered accredited college level courses. A fabricator with an associate degree and one year running a crew may already be eligible. Full time equivalency is a minimum of 2,000 person hours per year.
The examination
Sheet metal is a Division II category, so the certification exam consists of two tests: business and financial management of a contracting firm, and general knowledge of the sheet metal trade (rule 61G4-16.001). Both tests are open book and consist of multiple choice questions, and both are scheduled as computer based tests through Pearson VUE once Professional Testing, Inc. approves the application (DBPR construction examination information). A candidate needs a score of 70 percent or higher on each test to pass.
The business and finance test weights its content this way, under board rule:
| Content area | Weight |
|---|---|
| Establishing the contracting business | 11% |
| Managing administration duties | 26% |
| Managing trade operations | 10% |
| Conducting accounting functions | 32% |
| Managing human resources (staffing) | 6% |
| Complying with government regulations | 15% |
The sheet metal trade knowledge test weights its content this way:
| Content area | Weight |
|---|---|
| Preinstallation and site work | 15% |
| Industrial duct fabrication | 25% |
| Architectural sheet metal | 10% |
| Fabrication of other sheet metal structures | 10% |
| Installation of sheet metal systems | 25% |
| Safety and equipment | 15% |
Two waivers matter here, and they are easy to confuse with each other. An applicant with a baccalaureate degree in building construction, or a related degree the board approves by rule, from an accredited 4 year college, with a grade point average of 3.0 or higher, takes only the business and finance test (F.S. 489.113(1)). Separately, a current, active licensee already certified or registered in most other Division I or Division II categories can skip the business and finance test when applying for sheet metal, since the rule assumes that test does not need to be repeated, so long as the licensee is not under investigation or prosecution for a Part I violation and has no discipline beyond a notice of noncompliance, a letter of guidance or a citation (rule 61G4-16.0015). Neither waiver excuses the sheet metal trade knowledge test itself.
Board fees
Rule 61G4-12.009 prescribes the fees. The headline figure is $335, and it is collected in pieces at different moments rather than as one payment.
| Fee | Amount | When |
|---|---|---|
| Application and examination | $335 total, nonrefundable | Across the steps below |
| Paid on scheduling | $135 | When you schedule the tests |
| Examination administration | $80 | For each test administered |
| Processing after passing | $40 | After you pass |
A failed or missed test repeats the first two charges. For an unsuccessful examinee, or an approved applicant who failed to appear, the next test costs $135 on scheduling plus $80 per test administered, all nonrefundable. The same rule sets $200 for biennial renewal, $100 for a registration application, $50 for the application and initial issue of a business organization certificate, $50 to transfer a license between entities and $25 for a delinquency fee.
Fees are set by the board or testing vendor and can change. Verify the current amount with the provider before you pay.
Insurance and the audit nobody expects
Rule 61G4-15.003 requires a signed affidavit attesting that the applicant has obtained and will maintain public liability and property damage insurance for the life of an active license. A sheet metal contractor carries $100,000 in public liability and $25,000 in property damage, the same floor the rule sets for roofing, mechanical, plumbing, pool and solar.
The obligation is continuous, and the board verifies it by sampling. It conducts random sample audits of licensees by zip code area, and a selected licensee has 30 days from the mailing of a certified mail request to submit proof of coverage. The certificate of insurance must carry the exact name of the business organization the applicant qualified, name the board as certificate holder, state the policy number and effective and expiration dates, and provide for a 30 day written cancellation notice. Letting coverage lapse is a violation of the rule in its own right, separate from any claim.
Certified or registered
Certification is the statewide credential. Registration under F.S. 489.117 requires no state examination, but it authorizes contracting only in the counties, municipalities or development districts where the registrant has complied with local licensing requirements, and only for the type of work the registration covers. A registrant must report each local jurisdiction and category to the board within 30 days of obtaining the local certificate of competency.
For a company bidding across several Florida markets, registration usually costs more in lost opportunity than certification costs in fees. For a company working one county, it can be the faster route.
The qualifier rule
The certificate is earned by a person and used by a company. Under F.S. 489.119, a business organization may operate in a category of contracting only if its qualifying agent is certified or registered in that category. No sheet metal qualifier, no sheet metal company. A qualifying agent qualifies the company, meaning an owner or a full time W-2 employee of the company takes on final approval authority for its construction work and most of its business matters, as explained in our qualifying agent explainer; companies that need help placing one can see hire a qualifying agent or our contractor qualifier services.
The qualifying agent files an affidavit attesting to final approval authority for all construction work performed by the business organization, and final approval authority on all business matters including contracts, specifications, checks, drafts and payments, except where a financially responsible officer has been approved. That is a real duty, not a signature.
The replacement clock is strict. If the qualifying agent is the only certified or registered contractor affiliated with the business, the company notifies the department and has 60 days from the termination of the affiliation to employ another qualifying agent. The company generally may not engage in contracting during the gap, except under a temporary credential the executive director or board chair may grant, and even then only to complete incomplete contracts.
That is the structural reason sheet metal and air handling companies plan qualifier coverage before they need it. Every qualifier we place is a full time W-2 employee of the company that needs one, not an outside signature.
Step by step
- Confirm the category against the gauge threshold and the air handling language in F.S. 489.105(3)(d), and decide whether mechanical or air conditioning is the better fit.
- Choose certification for statewide work or registration for a single jurisdiction.
- Pick your eligibility route from F.S. 489.111(2)(c), counting 2,000 person hours as one year.
- File the application with the $335 application and examination fee.
- Schedule the business and finance test and the sheet metal trade knowledge test, paying $135 on scheduling and $80 for each test administered.
- Pass both tests at 70 percent or higher, then pay the $40 processing fee.
- Bind the $100,000 public liability and $25,000 property damage coverage a sheet metal contractor must carry, and sign the affidavit.
- Qualify the business organization under F.S. 489.119 and file the qualifying agent affidavit.
Renewal and continuing education
Certificates and registrations renew every two years for $200, or $50 on inactive status. Each licensee must complete at least 14 classroom hours of board approved continuing education per biennium, including at least 1 hour each on workers compensation, business practices, workplace safety and laws and rules (F.S. 489.115(4)(b); rule 61G4-18.001).
Fees are set by the board or testing vendor and can change. Verify the current amount with the provider before you pay.
Questions sheet metal contractors ask
How much does the license cost in total? The board side is fixed and published: $335 for the application and examination, $135 on scheduling, $80 per test, $40 after passing, then $200 every two years. What moves is the rest, including insurance premiums priced to your payroll and loss history, the time cost of documenting experience, and whether you need a qualifier.
Can my general contractor license cover duct work? No. F.S. 489.113(3) requires a contractor to subcontract all sheet metal work unless it holds a certificate or registration in the trade, and none of the carve outs in that subsection reach sheet metal.
Is duct cleaning licensed work? Duct cleaning and equipment sanitizing that requires at least a partial disassembling of the system is inside the statutory scope. Cleaning that does not require disassembly is not described that way in the statute.
Does the license have a project size limit? No. The statute describes services that are unlimited in the sheet metal trade.
Does a building construction degree waive the trade knowledge exam? No. A 3.0 GPA baccalaureate degree in building construction waives only the business and finance test for a new applicant; the sheet metal trade knowledge test still has to be passed.
Is sheet metal Division I or Division II? Division II. F.S. 489.105(3) splits contractors into Division I, paragraphs (a) through (c), and Division II, paragraphs (d) through (q). Sheet metal is paragraph (d), the first entry in Division II.

Florida runs its Division II categories on one statutory frame, so the fee schedule, insurance floor and experience routes in this guide repeat across them.

Marshall Schofield and Jeremiah Jaskulski built The Licensing Company around the gap this article describes: companies with the crews, the shop and the backlog, and no licensed individual able to qualify the business. Qualifiers are placed as full time W-2 employees, and nothing else. If your company needs a sheet metal qualifier in Florida, call 615-219-2110 or start at hire a qualifying agent.
