Excavation Insurance Group built a dedicated coverage requirements guide for excavation and grading contractors in every state. Licensing rules, 811/one-call notification laws, and workers’ compensation requirements are not the same from one state to the next, and treating them like they are is how contractors end up underinsured or non-compliant the moment they cross a state line. This hub is the index to all 50 state pages, each one built specifically for excavation and site-work risk in that state.
WHY STATE REQUIREMENTS MATTER FOR EXCAVATION CONTRACTORS
Excavation is one of the few trades where the rulebook genuinely changes at the state line, and sometimes at the city line inside it. A contractor who’s been running clean in one state can walk straight into a compliance problem, or a coverage gap, by assuming the next job site plays by the same rules. Three areas trip up more contractors than any others: contractor licensing, 811/one-call notification, and workers’ compensation.
Licensing is not universal. Some states issue a statewide license specifically for excavation, grading, or general contracting, and you can’t legally bid work without it. Other states have no statewide license requirement at all for excavation work, leaving licensing (if any) to the city or county. That means the exact same scope of work can require a state license exam in one state and nothing more than a business registration two states over. Assuming your home state’s rules travel with you is one of the fastest ways to lose a bid, or worse, get shut down mid-job.
Every state has an 811 law, but the details aren’t standardized. Call-before-you-dig is federal in spirit, tied to the national 811 number, but the actual law that governs it, the notice window before you can break ground, and the penalties for skipping it are all set at the state level. One state might require 48 business hours’ notice and cap first-offense penalties in the low hundreds. Another might require ten days’ notice and stack penalties into the thousands for repeat violations. The depth threshold that triggers the law can shift too. None of that is optional reading if you’re mobilizing equipment into unfamiliar territory.
Workers’ compensation is mandatory almost everywhere, with one big exception and four unusual ones. Texas is the only state that doesn’t require most private employers to carry workers’ comp at all, making it an opt-out system rather than a mandate. Every other state requires it in some form once you have employees. But four states don’t let you buy that coverage from a private insurance carrier the way you’d expect: North Dakota, Ohio, Washington, and Wyoming run monopolistic state funds, meaning employers are required to purchase workers’ comp directly through a state-administered fund rather than the open insurance market. If you’re used to shopping workers’ comp like every other line of coverage, that structure catches contractors off guard the first time they take on work in one of those four states.
None of this is a reason to avoid expanding into new states, it’s a reason to check the requirements before you bid, not after you’re already on site. That’s exactly what the state pages below are built to do: give you the licensing, 811, and workers’ comp picture for wherever your next job is, state by state, so your coverage and your compliance keep pace with where you’re actually working.

Every state below has its own dedicated page covering licensing requirements, 811/one-call rules, General Liability expectations, and workers’ compensation law specific to excavation and grading contractors in that state.
QUESTIONS ABOUT STATE REQUIREMENTS
Do I need to update my coverage when I bid work in a new state?
Check before you bid, not after you win the job. Your existing General Liability policy may or may not extend the way you need it to in a new state, and licensing or bonding requirements can differ enough that you need paperwork lined up before mobilization, not during it. Excavation Insurance Group reviews multi-state operations as part of every coverage review, so you’re not finding out about a gap on someone else’s job site.
What does “811” actually mean, and is it federal or state-specific?
811 is the national call-before-you-dig phone number, so the number itself is the same everywhere. But the actual law behind it, how much notice you have to give, what depth triggers the requirement, and what the penalties are for skipping it, is set state by state. Dialing 811 in two different states can mean two very different notice windows and two very different consequences for getting it wrong.
Why don’t some states require a contractor license for excavation work?
Licensing authority varies by state, and some states simply choose to regulate excavation and site work at the city or county level instead of issuing a statewide license. That doesn’t mean there’s no oversight, it just means the requirement (if any) shows up locally instead of from the state. Always check both levels before assuming you’re clear to work.
What are the monopolistic workers’ comp fund states, and why do they exist?
North Dakota, Ohio, Washington, and Wyoming require employers to purchase workers’ compensation through a state-administered fund rather than a private insurance carrier. These systems predate the modern private workers’ comp market in those states and were never opened up to competition the way most states eventually did. If you’re taking on work in one of these four, your workers’ comp purchasing process looks different from what you’re used to elsewhere.
How do I know which state’s rules apply when I’m working near a state border?
The rules that apply are determined by where the physical job site sits, not where your company is based or licensed. A crew headquartered in one state but digging just across the line is subject to that other state’s licensing, 811, and workers’ comp requirements for that job. Don’t assume home-state rules travel with the truck.
