|---|---|---|---|
| 5183 | PLUMBING NOC AND DRIVERS | $2.737 | $2,623 |

Worked example for a Tampa crew
Picture 6 employees of a Tampa plumbing business, each earning the Hillsborough County average, for $406,000 of payroll in class 5183.
At $2.737 per $100, the manual premium is about $11,112 a year, or about $1,852 per employee, before your experience modifier, credits and fees.
If the business were placed in the FWCJUA instead, the 2026 surcharges of 93% (Tier 1) and 183% (Tiers 2 and 3) would put the same payroll at about $21,447 or $31,448.
The experience modifier then moves that number: at a 0.85 mod the Tampa crew would pay about $9,445, and at a 1.25 mod about $13,890.

Permits and licensing in Tampa
Before a Tampa plumbing job starts, the contractor pulls plumbing permits from the City of Tampa Construction Services Division, and state law requires proof of workers' comp or an exemption as part of that application.
To register a license with the City of Tampa Construction Services Division, every license type must show a certificate of workers' compensation insurance or proof of exemption, along with the state license and a registration form. Florida's 2021 occupational-licensing preemption (HB 735) ended most local contractor licensing once the grandfather period expired on July 1, 2025, so most Tampa contractors now work under a state-certified or state-registered license and use Hillsborough County's HillsGovHub portal. Tampa sits on the bay, and storm surge risk shapes a large share of repair work after every hurricane season.
Tampa's work mixes downtown and Water Street towers, Westshore office projects, Port Tampa Bay and MacDill Air Force Base, hospital expansions, and a large residential market across Hillsborough County. Storm repair after Helene and Milton can put unfamiliar subs on a job, so check every sub's certificate in the state Proof of Coverage database. Contractors who keep current certificates on file with their regular GCs get mobilized faster after a storm. Ybor City is a National Historic Landmark District, and exterior changes there go through the city's Barrio Latino Commission, which adds a design review step for roofers, masons and window installers. Downtown, the Water Street district has added towers, hotels and offices along the Channel District, while Tampa Electric and the city's water department coordinate the utility side of new connections.
- Hurricanes Helene and Milton in 2024 drove a long repair cycle across Tampa Bay, and payroll for repair trades rose with it.
- Port Tampa Bay, MacDill Air Force Base and the hospital systems keep institutional and industrial jobs in the mix.
Common claims for plumbing contractors in Tampa
Tampa plumbers saw heavy demand for flood-damage repairs in low-lying neighborhoods after the 2024 storms, on top of steady new-construction work. A high water table near the coast means wet trenches and more dewatering on underground work.
- Trench collapses and struck-by injuries on sewer and water-line work
- Back injuries from lifting water heaters and fixtures
- Cuts and puncture wounds from pipe and tools
- Exposure to sewage and mold on repair calls
- Slips on wet floors and in flooded crawl spaces

Questions from Tampa plumbing contractors
What does workers' comp cost plumbing contractors in Tampa, FL?
Start from payroll. Hillsborough County plumbing and HVAC contractor firms paid about $67,600 per employee in 2023, and class 5183 costs $2.737 per $100 of it, so each Tampa worker carries roughly $1,852 of manual premium a year. Your experience modifier, credits and the carrier's pricing move the final figure from there.
How many plumbing and HVAC contractor businesses operate in Tampa?
The Census Bureau's 2023 ZIP Code Business Patterns lists 367 plumbing and HVAC contractor establishments in ZIP codes with a Tampa postal address, out of 631 across Hillsborough County and 9,351 statewide. Each of them needs workers' comp once it has an employee, so a current certificate is part of almost every Tampa bid package.
Where do plumbing contractors in Tampa get permits, and is proof of coverage required?
Permits inside Tampa come from the City of Tampa Construction Services Division. County-level trade licensing in Hillsborough County runs through Hillsborough County contractor licensing (HillsGovHub). Construction employers in Tampa need workers' comp from their first hire; the policy or exemption shows up in the state's Proof of Coverage records that permit offices check.
Is a plumber who only does service calls rated lower?
No. Service and new-construction plumbing both fall in 5183. Premium differences come from payroll, losses and the experience modifier, not from the type of plumbing work.
Do Tampa contractors have to register their insurance with the city?
Yes. The City of Tampa's contractor registration asks for a certificate of workers' compensation insurance or proof of exemption, along with the state license. Keep the registration current when your policy renews, or permits can be held.
Does hurricane season change workers' comp costs for plumbing contractors in Tampa?
Rates stay fixed for the policy year. What moves is payroll: after a storm, Tampa plumbing contractors often add crews and overtime, and the year-end audit charges premium on every added dollar. Tell your agent when you staff up so the deposit premium keeps pace.
