Contractor Insurance Explained. What Every Renovation Shop Actually Needs

Every renovation shop has an insurance conversation they keep postponing until a real incident forces it. The problem is that by the time the incident hits, options are limited and premiums have doubled. This guide covers every policy a serious renovation contractor should carry, what each one actually covers, and what a typical shop spends on premiums in 2026.

The five policies that matter

1. General liability (GL)

Covers third party property damage and third party injury caused by your work. If your crew scratches a $12,000 dining table during install, GL covers it. If a homeowner trips on a saw cord and breaks their wrist, GL covers it. Standard coverage limits are $1M per occurrence and $2M aggregate. Annual premium for a small renovation shop is typically $600 to $2,400 depending on revenue and claims history.

This is the one policy no client should ever let you skip. Most contracts require a Certificate of Insurance (COI) naming the client as additional insured for the duration of the project. If you cannot produce a COI within an hour, you are not going to get the job.

2. Workers compensation

Legally required in most US states and Canadian provinces the moment you have any employees. Covers medical costs and lost wages if a crew member gets injured on a job site. Premiums are usually calculated as a percentage of payroll and vary wildly by state and trade classification. Expect 4 to 12 percent of payroll for renovation trades.

You cannot legally 1099 your way out of workers comp for full time workers. Misclassification is a common contractor mistake that catches up during audits and can trigger 3 to 5 years of back premiums plus penalties.

3. Commercial auto

Personal auto policies do not cover a vehicle used primarily for business, even if the truck is titled in your name. Commercial auto is required the moment your crew is driving to job sites, hauling materials, or carrying tools. Annual premium is typically $1,200 to $3,000 per vehicle.

Skip this and one accident during a job run can void your personal auto coverage entirely. That is a catastrophic exposure.

4. Tools and equipment (inland marine)

Covers your tools when they leave the shop. Van gets broken into overnight at a job site, contractor grade table saw gets stolen off the driveway, cordless kit walks off a scaffold. Standard shop kit is easily $15,000 to $60,000 worth of replaceable inventory. Annual premium is typically $250 to $800.

Homeowners insurance almost never covers tools left at another person's property, and general liability does not cover your own equipment. Inland marine is the specific policy for this.

5. Umbrella policy

An extra $1M to $5M of coverage that kicks in when a claim exceeds your GL or auto limits. When a client sues for $2.5M because a plumbing rough in leak damaged a whole floor of hardwood, the underlying GL policy might cap out at $1M and umbrella covers the rest. Annual premium is typically $500 to $1,500 for $1M of umbrella coverage.

The math is asymmetric. A single catastrophic claim without umbrella can end a shop. Umbrella premium is small enough that most established renovation contractors carry it as basic hygiene.

What you can skip until later

• Professional liability (E&O). Relevant if you provide design services or engineering opinions. If you are pure build execution, skip until you add design services.
• Cyber liability. Relevant once you store hundreds of client records with sensitive data. Modern CRMs handle much of this via their own SOC 2 posture.
• Employment practices liability (EPLI). Relevant once you have 5 plus employees and a real HR function.

How to actually shop for this

Do not buy insurance direct from a big carrier's website. Work with a commercial insurance broker who specialises in construction trades. A good broker will bundle GL + auto + workers comp + tools + umbrella into one relationship with one carrier, run competitive quotes annually, and file COIs on your behalf for every project. Their commission is baked into your premium either way, and a specialist saves you from the classic mistake of buying too little coverage or the wrong classification code.
