What Activities Require Excavation Permits in California?

In California, permits for excavation are required for certain construction activities. The specific requirements for permits can be found in the California Code of Regulations, Title 8, Section 341. Here are some key points regarding excavation permits in California:

  • A Project Permit is required to demolish or dismantle any building or structure more than 36 feet in height.
  • An Annual Permit is required for certain construction activities, such as constructing a trench or excavation 5 feet or deeper into which any person is required to descend.
  • The permit requirements apply to employers who will directly engage in permit-required activities, including the construction of trenches or excavations.
  • The purpose of the permit is to ensure compliance with safety regulations and to protect the well-being of workers.
  • Excavation permits are critical components of the excavation procedure and are always required for any excavation.

Who Needs to Obtain an Excavation Permit?

Excavation permits are typically required for the party who will be directly overseeing or conducting the actual excavation work. This is usually the general contractor, subcontractor, or company responsible for the digging activities. Some key details:

  • For public infrastructure projects like roads or highways, the government agency usually obtains permits.
  • On private construction projects, permits fall on the builder or contractor.
  • Utility companies doing excavation obtain their own permits for installing or repairing underground lines.
  • Homeowners planning DIY excavations would need to secure permits themselves in many cases.

Frequently Asked Questions About Excavation Permit Requirements

Do I need a permit to dig up my backyard?

It depends on what you are excavating and how deep you plan to dig. Small superficial landscaping projects usually don’t require a permit. But deep excavations, especially those with workers entering the hole, may need permits for safety reasons. Check with your local building department to be sure.

Does a contractor need to get the excavation permit or is it my responsibility as the homeowner?

Typically the party doing the actual excavation work needs to secure the required permits. For home improvements, contractors usually obtain necessary permits as part of their services. But it’s best to clarify permit responsibilities with your contractor up front.

What if I’m excavating a trench on private property for agricultural or drainage purposes? Is a permit required?

If the trench is less than 5 feet deep, not entered by workers, and on private land owned and controlled by you, a permit may not be required in some areas. However, agencies still recommend appropriate safety steps be taken. Check with your county or state to understand exemptions.

Can I get an annual excavation permit to cover small projects throughout the year on my property?

Yes, annual excavation permits are common for contractors who need to do repeated small-scale excavation jobs in a local area over an entire year. Homeowners can also inquire about annual permits for minor projects on their land.

How long does it take to get an excavation permit once I submit my application?

Review times vary greatly by jurisdiction. Some focus on safety plan adequacy rather than lengthy delays. But expect at least 1-2 weeks for review, inspection scheduling, and processing time after submitting a complete application package. Urgent permits for emergency utility work may be expedited.

What happens if I get a permit but then need to modify my excavation project?

Contact the permitting agency promptly about any changes in scope or methodology that differ from your approved permit. Depending on extent, modified permits can typically be issued to cover revised excavation plans. Key is keeping the agency updated on current conditions.

Are there special requirements for excavating near other structures or utilities?

Yes, extra precautions apply. You may need vacuum excavation, worker certifications, special shoring methods, and coordination with affected utilities. The permit review aims to ensure necessary steps are taken for these sensitive areas.

If I’m hiring a contractor for an excavation job, can I rely on them to handle the permit process?

It’s common for contractors to obtain required permits as part of their work. But it’s wise to ask for confirmation that permitting is included and discuss who will cover any associated fees. Reviewing project timelines to factor in permitting is also recommended.


Obtaining necessary excavation permits is one of the most vital steps in undertaking any project involving digging or trenching. While permit requirements vary, they aim to ensure projects follow safety regulations and protect workers from hazardous conditions. Check with your local jurisdictions to determine which rules apply for your planned excavation work. Allow sufficient time for detailed applications, review periods, and inspections required during the permitting process. Adhere to all conditions while excavating to avoid fines or delays. Leverage the right permits for a compliant and safe project from start to finish. With this comprehensive understanding of excavation permitting, you can confidently embark on your next construction project involving earth moving or digging
