Markout Laws Vary by State — Here’s What You Should Know

If you work in excavation or construction, you already know that calling before you dig is the law. But what many contractors don’t realize is that markout laws aren’t the same everywhere. Each state sets its own requirements for how far in advance you must request a markout, how long a ticket stays valid, and even how deep you can dig before a markout is required.

Understanding these differences is essential — especially if your company operates in multiple states.

Key Differences Between States

Here are a few examples that show just how much the rules can vary:

• New Jersey – Requires at least three business days’ notice before excavation. A markout ticket remains valid for 45 business days.
• Texas – Requires two business days’ notice and specifies a 16-inch minimum digging depth that triggers the need for a markout.
• California – Requires two working days’ notice, and tickets are valid for 28 calendar days.
• New York – Requires two to ten business days’ notice, depending on the work type, and tickets must be renewed every 10 business days.

Why These Differences Matter

Failing to follow your state’s specific markout rules can lead to:

• Fines or penalties
• Liability for damaged utilities
• Delays in your project schedule
• Increased safety risks to workers and the public

Every state’s “Call Before You Dig” system — whether it’s 811 or a local service — has detailed requirements. Taking the time to understand them can save your business from costly mistakes.
