Plumbing licenses, insurance & permits
Not legal advice. This is general information to help you plan — not legal advice. Licensing, insurance, and permit requirements change and vary by state, county, and city. Always confirm with your state licensing board and a licensed professional before you rely on it.

- General Liability InsuranceCommercial customers almost always require a current COI before awarding work.
- Commercial Auto InsurancePersonal auto policies exclude work use — commercial customers and many states require it.
