Reviewed October 1, 2026 · Tennessee plumbing contractors

Tennessee plumbing insurance requirements

What Tennessee requires for plumbing businesses

For a state contractor license, the board requires general liability coverage based on your monetary limit, plus workers’ compensation unless you show an exemption. The board’s insurance information sheet lists the details.

A licensing minimum is a floor, not a recommendation. Customers, general contractors and property managers often ask for higher limits, so get their requirements in writing.

Workers’ comp

Tennessee says construction businesses generally must carry workers’ compensation for everyone, including the owners; other businesses need it at five or more employees (TN Department of Labor). Confirm how this applies to you before you hire.

Local rules

Cities and counties can add their own requirements. Before you register locally or pull a permit, ask the building department whether it wants a certificate of insurance, a bond or workers’ comp proof on file.

Which policies should a Tennessee plumber compare?

Match coverage to the risk

Risk	What to ask about
A leak, flood or sewer backup damages a customer’s property, during or after a job	General liability that meets any license or contract limits, including products and completed operations. Ask how it handles water damage, mold, work in occupied homes and any exclusions for the kind of work you do.
An employee gets hurt	Workers’ comp under Tennessee’s rules. Give accurate payroll and job duties, and explain how you use subcontractors.
Your van or truck	Commercial auto for business use, the vehicles and everyone who drives them. General liability doesn’t cover your vehicle, and a personal auto policy may not cover a work van.
Tools, drain cameras, jetters and equipment	Tools and equipment (inland marine) coverage. Ask about theft from a vehicle, tools left on site overnight, rented equipment and deductibles.
A shop, stock or bigger contracts	Property coverage or a business owner’s policy, plus umbrella coverage if a contract asks for higher limits.

Describe the work you actually do

Tell the insurer whether you do service and repair calls, drain cleaning, sewer line work, excavation or trenching, gas piping, water heaters, backflow testing, new construction or commercial work. Mention subcontractors and any work in occupied buildings. A quote built on a narrower description, such as “handyman,” may not cover the jobs you take.

Ask what happens when your own work fails. Liability insurance isn’t a warranty. Fixing a bad joint and paying for the water damage it caused are often treated differently. Ask the agent to walk you through it.

Already insured and need a certificate?

Start with your current agent or insurer. For the board, follow its insurance information sheet for the liability amount tied to your monetary limit, and have workers’ comp proof or an exemption ready. For a customer, send their written insurance requirements, the project address and how they want the certificate holder listed.

A certificate only shows what your policy already covers. It doesn’t change the policy. Being listed as certificate holder is not the same as being an additional insured, so if a contract asks for additional insured status, a waiver of subrogation or primary wording, ask whether you need an endorsement. Put renewal dates on your calendar so required coverage never lapses.

How much does plumbing insurance cost in Tennessee?

There isn’t one Tennessee price. Your quote depends on the work you do, revenue, payroll, subcontractors, claims history, vehicles, equipment, limits and deductibles. We don’t have a reliable Tennessee average to share, and we won’t guess at one or promise a Simply Business price.

• Compare quotes with the same work description, limits, deductibles and policy dates.
• Ask for the full yearly cost, plus any installment or endorsement fees.
• Price workers’ comp and auto separately from general liability.
• If a quote is a business owner’s policy, check what it bundles so you don’t count coverage twice.
• Ask whether a payroll or revenue audit could change the final bill.

A cheap policy that excludes work you do is the wrong policy. Have the agent explain the differences before you choose on price.

Get your Tennessee insurance quote ready

1. Your legal business name, address, Tennessee contractor license number, classification and monetary limit, start date and experience.
2. The services you offer, your residential and commercial mix, typical job sizes and the area you cover.
3. Revenue, payroll, what each worker does, owners and subcontractors.
4. Vehicles, drivers, tools, equipment values and where they’re kept overnight.
5. Past claims, current policies and their end dates.
6. The certificate rules from each licensing office you deal with, and each customer’s written insurance requirements.

Before you take a job, ask the insurer to confirm in writing which work is covered, the exclusions, the limits and the start date. Asking for a quote doesn’t give you coverage. Simply Business offers insurance for plumbers, but whether a policy fits still depends on your business and the insurer.

Common Tennessee plumbing insurance questions

Does Tennessee require liability insurance or a bond for plumbing businesses?

For a state contractor license, the board requires general liability coverage based on your monetary limit, plus workers’ comp unless you show an exemption. The board’s insurance information sheet lists the details.

When do I need workers’ comp in Tennessee?

Tennessee says construction businesses generally must carry workers’ comp for everyone, including the owners. Other businesses need it at five or more employees.

Does general liability cover my van or a hurt employee?

Usually not. Those normally need commercial auto and workers’ comp. Read the actual policies rather than assuming a plumbing package covers everything.

Does forming an LLC replace insurance?

No. An LLC, your license and your insurance each do a different job. Our Tennessee LLC guide covers formation.

Is the minimum enough for a commercial job?

Not always. General contractors and commercial customers often ask for higher limits and extra endorsements. Read the contract before you bid and ask your agent about any gaps.
