Florida certifies fire protection system contractors in five classes under Chapter 633. See what each class covers, the experience routes, exam, insurance and how a company stays covered.
Sprinklers, standpipes, foam systems and underground fire mains are not licensed with the general and specialty trades. In Florida they fall under the State Fire Marshal and Chapter 633 of the Florida Statutes, which sets up its own certificate, its own exam and five contractor classes. If you bid fire protection work, you need to know which class matches the system you install.
For the wider picture of Florida licensing, start with the Florida contractor license page. This guide covers only the fire protection certificate, which sits outside the Construction Industry Licensing Board.
At a glance Regulator: the Division of State Fire Marshal, Florida Department of Financial Services. Law: Chapter 633, Florida Statutes. Class definitions are in section 633.102 and the certificate rules are in section 633.318. Classes: Contractor I, II, III, IV and V. Exam: written test for the class you seek, 70 percent to pass, offered at least twice a year. Insurance: $500,000 minimum for Contractors I, II, III and V, and $250,000 for Contractor IV.
The five fire protection contractor classes
Section 633.102 defines the classes by the kind of system each one may install. Pick the class by the work you want to do, not by the title that sounds biggest. The table below summarizes the scope.
| Class | What it covers | Notable limit |
|---|---|---|
| Contractor I | The full range of fire protection systems | Excludes preengineered systems |
| Contractor II | Water based systems: sprinklers, water spray, foam water, standpipes, piping, tanks and pumps | Excludes preengineered systems |
| Contractor III | Carbon dioxide, foam extinguishing, dry chemical and Halon or other chemical systems | Excludes preengineered systems |
| Contractor IV | Automatic sprinkler systems in detached one and two family dwellings and mobile homes | Limited to the NFPA 13D scope, no cluster units such as apartments or condominiums |
| Contractor V | Underground water based fire protection piping | Runs from the point of service to no more than 1 foot above the finished floor |
Contractors I and II may also design new systems of 49 or fewer sprinklers, plus certain alterations within stated limits. Contractors I, II and IV may design systems that meet NFPA 13D no matter how many sprinklers are involved. A Contractor V may inspect underground piping only under the direction of a Contractor I or II.
Who qualifies for each class
Every class requires the applicant to be at least 18 and of good moral character. The experience rules differ, and they are the part that stops most applicants. Section 633.318 sets them out.
| Class | Experience or license required |
|---|---|
| Contractor I | 4 years of proven employment experience as a Contractor I, or equivalent education and experience in both water based and chemical suppression systems |
| Contractor II | 4 years of verifiable experience as a Contractor I or II, or equivalent education and experience in water based systems |
| Contractor III | 4 years of verifiable experience as a Contractor I or II, or equivalent education and experience in chemical systems |
| Contractor IV | A certified plumbing contractor license under Chapter 489, plus at least 40 contact hours of State Fire Marshal approved training on NFPA 13D |
| Contractor V | A certified underground utility and excavation contractor or certified plumbing contractor license under Chapter 489, plus 4 years of verified experience or equivalent education and experience |
Contractors I through IV also need training and experience in both installation and system layout. Two of the five classes depend on a Chapter 489 license, which is why many Florida plumbers look at Contractor IV first. See the Florida plumbing license guide for how that underlying license works.
The exam
The Division holds at least two exams a year, and each applicant takes an objective written test for the class sought. The test covers the ability to lay out, fabricate, install, alter, repair and inspect fire protection systems, and it also tests business and financial management. The passing score is 70 percent.
Retakes cannot be scheduled sooner than 30 days after an administration, and an applicant may not be examined more than four times in one year unless already certified and changing classes. If you do not pass within the year, you file a new application and pay the fees again. A new application cannot be filed sooner than 6 months after the last exam.
If you pass but do not meet the other qualifications within a year, you must reapply, pay again, complete a training course through the State Fire College or an approved equivalent, and retake the exam. The Division must tell applicants the result in writing within 30 days after the exam.
Fees
Section 633.132 sets the contractor fees, charged per class.
| Item | Fee per class |
|---|---|
| Certificate initial application | $300 |
| Certificate biennial renewal | $150 |
| Permit initial application | $100 |
| Permit biennial renewal | $50 |
| Examination or reexamination | $100 |
An inactive license has its own application and renewal fee of $75. 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 certificate
You cannot hold the certificate without the required coverage. The statute requires comprehensive general liability for bodily injury and property damage, products liability, completed operations and contractual liability. The minimum is $500,000 for Contractors I, II, III and V and $250,000 for Contractor IV, and the Division may set higher amounts by rule.
Insurers must notify the Division within 30 days of a material change, cancellation or nonrenewal. The certificate stops being effective if the required insurance lapses. The State Fire Marshal can also demand proof of coverage at any time, and a certificateholder who does not answer within 30 days is suspended until proof is provided.
Inspector permits for employees
Employees of Contractor I or II certificateholders who inspect water based systems must hold a Division permit. The permit is valid only for the named employer, and the holder carries it with a photo ID. Permit holders need NICET Inspection and Testing of Fire Protection Systems Level II or equivalent.
A provisional permit is available to employees who hold NICET Level I and have started Level II. It lasts two calendar years and cannot be extended or renewed. After it expires, the employer must wait two years before requesting another provisional permit for that employee.
Penalties and license misuse
The State Fire Marshal can deny, suspend or revoke a certificate. In place of suspension or revocation, it can impose an administrative fine of up to $1,000 per violation, capped at $10,000 per proceeding, or place the holder on probation for up to two years. Violating Chapter 633 or a Division order is a second degree misdemeanor.
Florida law also treats license misuse as a crime. Section 633.124 makes it a first degree misdemeanor to use another person's license, certificate or permit, or to hold one and allow someone else to use it. A certificate belongs to the person who earned it and the work done under it.
How a company stays covered
The statute text ties the certificate to an individual and does not spell out how a company relies on that person. Confirm the structure you plan to use with the Division before you bid. In practice, a company that wants to install sprinkler systems needs a certified Contractor on its team.
That is where a qualifying agent fits. A qualifying agent qualifies a company as a full time W-2 employee, and the company is responsible for the work. Read what a qualifying agent is and the Florida qualifying agent guide for how the arrangement works, and see the guide to fire suppression contractor qualifying agents for the trade specific view.

Fire protection is one of several licenses a building project can touch. Alarm work has its own path under the electrical board, covered in the Florida alarm system contractor guide. The Florida specialty contractor categories page shows what sits under the construction board instead.
Frequently asked questions
Does a Florida plumber need a separate license to install sprinklers? A plumbing license alone is not the fire protection certificate. A certified plumbing contractor can qualify for the Contractor IV class, which is limited to systems in detached one and two family dwellings and mobile homes.
How long does a fire protection certificate last? Contractor certificates and permits renew every two years under the fee schedule in section 633.132.
How much does it cost to have a qualifying agent for a fire protection company? It varies with the class, the scope of work and how much of the role the company needs covered. See consultation options to talk through your situation, or learn how to hire a qualifying agent.
Is there a state exam for every class? Yes. Each applicant passes a written test for the class sought.
