Driveway Permits

Before You Begin

Please refer to the Grand County Road and Bridge Driveway Design Standards before you build your driveway and place your culvert.

Driveway Permit Requirements


You must submit and receive a Driveway / Access Permit Application prior to submitting a building application.

The following information is required when applying for a permit:
  • Owner / applicant name, mailing address, and phone number
  • Legal description of the property
  • Site / plot plan or drawing
  • $125.00 fee payment (cash or check)
  • Driveway marked with stakes
  • Utility Notification Center of Colorado (UNCC) ticket number (Ph: 800-922-1987 or 8-1-1) 
After the Road and Bridge Department receives the application for a driveway / access permit, we will schedule a site visit to check for need / size of a culvert, grade of driveway or variance, and condition of the ditch. The signed-off application you will receive must be included with your building application.

Note: A Certificate of Occupancy will not be issued without an approved driveway. An engineered driveway is required for a design variance condition.
