Plumbing in the SouthShore corridor

Plumbing is a state-licensed trade in Florida. That one fact does most of the work in this guide: it decides who may take the job, what has to be on the quote and the contract, and what you can do about it when something goes wrong. The rest is local — where the county is still converting septic to sewer, what the county wants a permit for, and what an insurer will ask about a house that is more than twenty years old.

What the license covers, and what it doesn’t

A Florida plumbing contractor is licensed for the whole trade: water and gas piping, sanitary and storm sewer lines, septic tanks, wells, pool piping, irrigation and solar water heating are all named in the statutory definition (§ 489.105(3)(m)). Two things sit at its edge. For drain cleaning and clearing, the same paragraph says no mandatory licensing requirement is established; Hillsborough County, though, says only a licensed plumbing contractor or the property owner may do the leak and toilet work it exempts from permits, which includes clearing stoppages. And an LP-gas licensee under chapter 527, or a gas-utility employee, may disconnect and reconnect the water lines when swapping an existing water heater without holding a plumbing license.

The license number tells you what kind of plumber you have. CFC is a certified plumbing contractor: a state exam, valid anywhere in Florida. RF is a registered plumbing contractor: a local competency test, valid only in the county or city that issued it (§ 489.117(1)(b)). Both are real licenses. An RF number from another county is not a license to work in Hillsborough.

Three things to check before anyone starts

The number. Florida requires the license number on every ad, bid, proposal and contract, whatever the medium, and on any lettered truck (§ 489.119(5)). A quote with no number on it is already out of compliance. Look the number up on the DBPR license portal.

The permit. Hillsborough County exempts three plumbing jobs from permits: stopping leaks in drains and water, soil, waste or vent pipes; clearing stoppages or repairing leaks in pipes, valves or fixtures, and pulling and resetting a toilet, so long as no valves, pipes or fixtures are replaced or rearranged; and cleaning a septic tank. The county page adds that if a concealed pipe has gone bad and has to be replaced with new material, that is new work and a permit is required, and that the exemption does not waive licensing; only a licensed plumbing contractor or the owner may do even the exempt leak and toilet work (hcfl.gov, work exempt from permits). By that rule a re-pipe or a sewer-line replacement needs a permit; the county does not list them separately. So does a new, replaced or relocated backflow assembly at a county water connection (hcfl.gov, backflow). A contractor who pulls the permit has to put their license number on the application.

The insurance. A licensed plumbing contractor must continuously carry at least $100,000 in liability and $25,000 in property-damage cover (Rule 61G4-15.003), and workers’ compensation as soon as they have one employee, because construction employers are covered from the first hire (§ 440.02). Ask for the certificate; the rule requires the cover.

The paperwork Florida puts in the contract

On a job over $2,500 on a home of up to four units, the contract must carry the construction lien notice in at least 12-point bold capitals, on the front page or a signed separate page (§ 713.015), and the Homeowners’ Construction Recovery Fund notice (§ 489.1425). If you pay more than 10 percent up front on work that needs a permit, the contractor must apply for it within 30 days and start within 90 days of it issuing, unless you agreed in writing to longer or they have just cause. If they don’t, a written demand by certified mail to apply, start or refund is the next step (§ 489.126).

One thing people get wrong: Florida’s three-day right to cancel applies to home solicitation sales, meaning the seller came to you uninvited. If you called the plumber, it generally does not apply (§ 501.025).

What unlicensed work costs you

Contracting, or advertising as available to contract, without a license is a first-degree misdemeanor; a repeat is a third-degree felony; and during a Governor-declared state of emergency a first offence is a felony (§ 489.127). The part that matters to you is the other half: an unlicensed contractor’s contract is unenforceable by them (§ 489.128). State law has an exemption for casual, minor work under $2,500 all-in, lost the moment the person advertises as a contractor or splits a job to stay under the cap (§ 489.103(9)); for plumbing leak and toilet work, Hillsborough County still says only a licensed plumber or the owner may do it.

You may do your own plumbing on a home you own and live in, as an owner-builder, if you sign the permit yourself and supervise the work in person (§ 489.103(7)); the county says the same (hcfl.gov). You may not hand that job to an unlicensed friend.

Older homes and the insurance inspection

Citizens Property Insurance requires a four-point inspection on any home more than twenty years old, and the inspector has to report the age, type and condition of the plumbing (citizensfla.com). The form asks whether the supply lines are original, partly or fully re-piped; what the pipes are made of, with cast iron and galvanized on the list; whether there is polybutylene; the water heater’s age and whether it has a temperature-pressure relief valve; and whether there is any sign of an active or prior leak (form Insp4pt 03/25). Under its homeowner, dwelling and mobile-home policy forms, Citizens will not write new business on a home over twenty years old that has polybutylene piping (Citizens answer 1713). A licensed plumber may sign the plumbing section of that form and nothing else.

If you are buying or insuring an older house in the corridor, those are the questions a plumber can answer for you before the inspector does.

Water, sewer and septic in the corridor

All six towns are in the county’s South-Central water service area (hcfl.gov). The water is Floridan-aquifer groundwater plus Tampa Bay Water’s regional supply, disinfected with chloramines, with a corrosion inhibitor added to limit lead and copper leaching from household plumbing (2025 Consumer Confidence Report). The county’s report does not publish a hardness figure, so we don’t either.

Sewer is not universal. The county is running septic-to-sewer conversions in Gibsonton and in Ruskin and Wimauma, because septic tanks load nutrients into the groundwater and the 1980s low-pressure sewer systems have proven unreliable (hcfl.gov). In the Ruskin and Wimauma project, homes on low-pressure sewer must switch to the new vacuum sewer, at no cost to the customer; homes on septic may choose to connect, and an owner who decides after the project’s connection period has closed hires their own licensed plumber, at their own expense (project FAQs). Backflow assemblies on county water must be tested every year by a county-registered tester, and the owner pays to repair or replace one that fails.

After a storm

Once the Governor declares an emergency, Florida’s price-gouging law covers services, not only goods, for 60 days unless extended; the test is a gross disparity against the average price in the 30 days before the declaration (§ 501.160). The Attorney General’s hotline is 1-866-9NO-SCAM (AG). While a state of emergency is in effect, unlicensed plumbing is a felony on the first offence. Gas water heaters are their own case: working on LP-gas systems and appliances needs a chapter 527 license from the Department of Agriculture (§ 527.02), while a plumbing contractor’s scope already includes natural and LP gas piping. Ask which license the person on your driveway is working under.

Before you hire

• A CFC or RF license number, on the quote, checked on the DBPR portal. If RF, it must be Hillsborough’s.
• Who pulls the permit for a re-pipe, sewer line or backflow job, under which license number; for a water heater, ask whether a permit is needed.
• A certificate of insurance: $100,000 liability, $25,000 property damage, and workers’ comp if they have employees.
• On a home job over $2,500, a written contract with the lien-law and Recovery Fund notices.
• If they take more than 10 percent up front on permitted work: permit applied for within 30 days, work started within 90 days of it, unless you agreed otherwise in writing.
• For a gas water heater: which license, chapter 489 or chapter 527, covers the gas side.
• On a house over twenty years old: what the pipes are made of, whether any is polybutylene, and the age of the water heater, so the four-point inspection holds no surprises.

Florida licenses this trade. Plumbing is a licensed trade in Florida. Drain cleaning alone is not; everything else in the trade is. Ask for the license number and check it before work starts.

License numbers for this trade start with CFC or RF. A C prefix is certified and valid anywhere in Florida; an R prefix is registered and valid only in the county that issued it.
