Encroachment Permit Applications, Forms and General Information

Permit Manual

The use of highways for other than normal transportation purposes may require written authorization from the Department of Transportation. Requests for ingress into the right of way requires the completion of an application to encroach. The Encroachment Permits Branch is responsible for overseeing statewide policy and procedure of encroachment permit activities within the state highway system. These activities are nonvehicular in nature. Some of these activities are highway improvement construction utility work, commercial filming, and special events such as parades. 

The Encroachment Permits Branch has the primary task of managing and completing permit application reviews and issuing permits. Encroachment permits reviewed by this branch range in value from $0 to $1,000,000 in construction costs.

Typical Permits completed by this branch include traffic control, intersection improvements, signals, driveways, under ground utilities, and special events. The permit applications are completed after being routed through designated sections for review and comment.

*Please note that Transportation Permits (Oversize Load and Trucking Permits) are all handled in Sacramento. Call 916-322-1297.
