What insurance does a contractor need?

A contractor typically needs four policies: general liability insurance for third-party injury and property damage, workers compensation once you have employees (required by law in nearly every state), commercial auto insurance for work vehicles, and inland marine coverage for tools and equipment. Contracts and license type determine the exact mix — most general contractors will not allow work to start without a current certificate of general liability insurance.

  • General liability — the foundation policy nearly every contract requires.
  • Workers compensation — required by law in nearly every state once you have employees.
  • Commercial auto — personal auto policies routinely exclude business use.
  • Tools and equipment (inland marine) — the most common uncovered loss for artisan trades.

Is general liability insurance legally required for contractors?

Some state licensing boards require liability coverage for certain license types, but for most contractors general liability is a contractual requirement rather than a legal one. In practice the distinction barely matters: general contractors, cities, and property managers require a certificate of insurance before work begins, so an uninsured contractor is an unhirable contractor.

When is workers compensation required?

In most states, immediately upon hiring your first employee — even part-time. Some states also require workers compensation for specific contractor license classifications regardless of whether they have employees, and those requirements keep expanding. Dean confirms the exact rule for your state when quoting. Operating without required coverage risks stop-work orders and license discipline.

Does a personal auto policy cover a work truck?

Usually not. Personal auto policies routinely exclude vehicles used for business, which means an accident on the way to a job site — with your ladder racks, tools, and signage on the truck — can be denied entirely. Commercial auto insurance covers business use, and hired and non-owned coverage extends protection when employees drive their own vehicles for work.

How fast can a contractor get insured?

Faster than most contractors expect. A general liability phone quote takes about 2 minutes with four inputs: trade, years in business, estimated revenue or payroll, and claims history. Binding often happens the same business day, and certificates of insurance are issued the same day — usually within hours — so a job never waits on paperwork.
