Simi Valley Excavation Permits - Contractors

Utilities and Infrastructure California 3 Minutes Read · published February 21, 2026 Flag of California

Overview

Contractors planning excavation in Simi Valley, California must secure the appropriate permits before breaking ground. Excavation in public rights-of-way, streets, sidewalks, and within restricted easements commonly requires an encroachment or excavation permit issued by the City of Simi Valley Public Works/Engineering division; private-site grading may also require Building & Safety review and a grading permit depending on scope and soil work[1].

Always call before you dig and confirm permit type with the City.

Process Overview

The typical steps for contractor-led excavations are: apply for the permit, submit engineering plans and traffic-control if required, obtain approvals and bonds, schedule inspections, and close out the permit with final submittals and restoration. Timelines vary by project complexity and completeness of submissions.

  • Submit permit application and plans.
  • Provide fees, bonds, and insurance certificates.
  • Wait for plan check and approvals; expect review time.
  • Schedule inspections during excavation and after backfill.
  • Maintain on-site permit and provide contact info for the inspector.
