Certified vs. registered plumbing contractor: which license in Seminole County?

What does the state offer a plumbing contractor to apply for?

The Department of Business and Professional Regulation (DBPR) lists several applications under the heading Certified Plumbing Contractor. This post rests on that one page, the DBPR Application Center page for certified plumbing contractors, which I read on October 13, 2026.

The page opens with the line "Welcome to the Department of Business and Professional Regulation's Application Center." Below that, it says its links let you get information on licensing requirements, check the status of an existing application, apply using a printable application, or use the online application system where one exists for the profession.

Suppose a plumber with a few years of residential service work wants to know where she stands. The page gives her several starting points:

• CILB 1, the initial and retake examination application.
• CILB 5-M, the application for a Certified Plumbing Contractor as an individual, listed separately for active and inactive.
• CILB 10, an endorsement application, listed as endorsement as an individual or to qualify a business.
• MVL 003, professional licensure for military personnel, veterans and military spouses.

The page lists these forms and says nothing about fees, experience requirements, exam content or processing time, so this post says nothing about them either. Those answers sit behind the links on the page itself.

One sentence on the page applies to nearly every plumber who already holds a license: "If you are updating or changing the status of an existing license or licenses, you will most likely be required to submit an application." If the way your license is held changes, or the business it supports changes, you usually need a form.

Is the license held as an individual or through a business?

The page separates a Certified Plumbing Contractor as an individual (CILB 5-M) from a Certified Plumbing Contractor who is qualifying a business (CILB 6-M). The first is the license in a person's own name. The second ties the contractor to a business entity as its qualifier. The page does not explain what qualifying means in legal terms, so for the effect on liability, supervision or who may sign permit applications, go to DBPR.

The page does show how many ways the two arrangements can change. It lists forms for each of these:

• Qualifying an additional business entity as a business or as an individual (CILB 7-M), or with an existing license (CILB 9).
• Adding or changing a qualifying agent (CILB 24).
• Adding, changing or removing a Financially Responsible Officer (CILB 8).
• A name change for a construction business entity (CILB 23).
• Moving between inactive and active status (CILB 11 for inactive to active, CILB 14 for active to inactive).
• Changing from individual to qualifying business (CILB 15), or from individual to qualifying an additional business (CILB 16).
• Moving from one qualified business to another (CILB 18), or to another while qualifying an additional entity (CILB 19).
• Combining a reactivation with qualifying a business (CILB 12) or an additional business entity (CILB 13).

A vendor should know which of these describes the license today. Suppose a plumber qualified a company three years ago, the company has since been renamed, and the plumber is about to send an insurance certificate and a license number to a new client. The name on the license, the name on the certificate and the name on the invoice should match, and the page shows that a name change for a construction business entity has its own form (CILB 23). Whether that form fits a given renaming is a question for DBPR.

A license that has gone null and void is a different problem. The page lists a form to reinstate a null and void certification (CILB 26). It does not say how a certification becomes null and void, so this post does not guess. If your record shows that status, that form is where the page points.

The table repeats what the page lists and adds no eligibility rules. Use it only as a starting point for matching a situation to a form, then read the requirements on the DBPR link for that form.

Where does a registered contractor fit?

The page gives a registered contractor a pathway called "Certification of Registered Contractor (Grandfathering)". It appears in several versions:

• As an individual, active or inactive (CILB 29).
• Qualifying a business (CILB 30).
• Qualifying an additional business entity, as a business or as an individual (CILB 31).

That is all the page establishes. It does not say what a registered license is, where one may be used, who is eligible for grandfathering, or whether any deadline applies. The comparison in this post's title, certified against registered, cannot be answered from the page alone, and a post that claimed otherwise would be guessing at your license.

What can be said is narrow. The page presents certified plumbing contractor applications as the main menu and lists grandfathering as a way for a registered contractor to move into certification. If you hold a registered license, or you are not sure which kind you hold, look up your own record and then read the grandfathering link on the DBPR page for eligibility.

A hypothetical shows why. Suppose a plumber has worked for years under a registered license and a property manager asks, in a vendor questionnaire, whether the license is certified or registered. An answer from memory can be wrong in either direction. The answer printed on the plumber's own DBPR record cannot.

How can I check a license before applying to a network?

Use the DBPR portal's own tools. The menu at the top of the Application Center page lists Apply for a License, "Verify a Licensee", View Application Status, Unlicensed Activity Search and File a Complaint. The page does not describe what each tool returns, so open them rather than assume.

Three habits are worth having before you apply anywhere:

1. 1Look yourself up through Verify a Licensee and read the record the way a stranger would. Note the license number, the name it is issued under and the status it shows.
2. 2If you have a pending application, use View Application Status so you know whether you have a license to show or a pending request.
3. 3Keep the license number ready to paste into any vendor form, and use the same business name on your quote, your invoice and your insurance certificate.

Managers and networks vet vendors through the same DBPR license search, which our post on how to vet a maintenance vendor in Florida covers from the manager's side. Whether a given job needs a license at all is a separate question. Our guide to Florida's handyman license exemption covers where that line falls for handyman work.

The page footer adds one more detail. It says that under section 455.275(1) of the Florida Statutes, effective October 1, 2012, licensees under chapter 455 must give DBPR an email address if they have one, that the email may be used for official communication, and that email addresses are public record. If you do not want a personal address made public, the page says to provide an address that can be. Check which address your own record shows.

What about Seminole County permits?

This post does not say which plumbing work needs a permit in Seminole County, or what the county or any city inside it requires of the contractor who pulls one. The only source here is the state's application page, and it is silent on permits. A statement about county permits would have no source, so none is made.

That gap matters for a plumber working around Orlando, because the license is only one part of a permitted job. The state page lists the applications for holding or changing a license. It does not say what a local building office will ask for when you apply for a permit, which jobs it wants a permit for, or how it treats a business qualified under someone else's license.

To settle it, ask the office that would issue the permit for your job, before you quote. Seminole County and the cities inside it each have their own building offices, and the answer can depend on where the property sits. Ask in writing so you can refer to the answer later.

How does this connect to working through 1Stop?

1Stop Service Pro takes insured trade vendors, licensed where the trade requires it. Whether your trade requires a license is a question for DBPR, so check your record before you apply.

In Seminole County, 1Stop covers every trade, with no emergency response target yet. An emergency request in the county gets a call back saying whether 1Stop can cover it, and a response target for a trade is published once an approved vendor covers it in the county. Plumbing is one of those trades.

The terms for vendors are short. There is no listing fee, lead fee or percentage. You invoice one company, 1Stop, and you are paid net-14. 1Stop is new and pre-launch, so there are no job counts or customer figures to point to, and this post gives none.

If your license is in order and you work in Seminole or the surrounding counties, the vendor application is the next step. If you are still deciding which DBPR form fits your situation, finish that first, because the application asks for a license number you can stand behind.
