Quick answer
A Florida plumbing contractor usually needs general liability, workers' compensation, commercial auto for service vans and equipment coverage for tools. Certified and registered plumbing contractors must keep at least $100,000 of public liability and $25,000 of property damage coverage for the life of the license (Rule 61G4-15.003), and a construction business needs workers' comp from its first employee. Water damage from a leak after the job is the trade's signature risk, so read how the policy handles it.
Coverage a plumbing contractor usually needs
| Coverage | What it's for |
|---|---|
| General liability | Water damage to a client's home or a building from your work, during the job or after it's finished (completed operations), and injuries at the site. Some policies limit water damage or add a mold exclusion, so read the endorsements. |
| Workers' compensation | Back injuries, cuts and falls, and trench work. Required from the first employee in construction. |
| Commercial auto | Service vans and trucks, and the parts and tools inside them on the road. |
| Equipment (inland marine) | Jetters, sewer cameras, pipe threaders, locators and trailers, including theft from vans. |
| Contractors pollution liability | Sewage backups, mold and other contamination claims. General liability policies usually exclude pollution, and many exclude mold. |
| Umbrella or excess liability | Higher limits that general contractors and commercial jobs often require. |
Florida and federal rules that apply
- To get or renew a certification or registration, a plumbing contractor signs an affidavit that it carries workers' compensation and public liability and property damage insurance (section 489.115(5)). Rule 61G4-15.003 sets the plumbing minimums at $100,000 of public liability and $25,000 of property damage, kept continuously, with the certificate showing the exact name of the business the license qualifies.
- A construction business needs workers' compensation once it has one employee (section 440.02), and every building permit application needs a certificate of coverage or an exemption certificate (section 440.103).
- A contractor is responsible for workers' compensation for a subcontractor's employees when the subcontractor hasn't secured it, and must collect proof of the sub's coverage or exemption (section 440.10).
- Locally, Polk County's Building Division asks a state certified contractor registering with it for a general liability certificate and a workers' comp certificate or exemption in the license holder's name, with Polk County Building Division as certificate holder.
