Encroachment Permits

If you wish to perform any work in the public right-of-way, this generally includes the sidewalk, curb, gutter, planting strip, and driveway, you will need to submit a completed Encroachment Permit application along with a certificate of insurance & additional insured endorsements, street improvement plans and/or traffic control plans for the proposed work. There is a separate plan check fee. The cost of an Encroachment permit is based on the permit fee, technology fee, and the number of required hours of inspection determined by the Public Works Inspector. Please refer to the Public Works Fee Schedule for a breakdown of the cost of the permit. If you have any questions or concerns, please contact the Engineering Services Division by phone at (714) 993-8148 or email at
