Amendment to a Previously Approved Subdivision Permit

What is the process?

Step 1: Identify the Original Map Number

Identify the original map number.

Step 2: Schedule Pre-Application Meeting (Optional)

Pre-application meetings are intended to aid prospective applicants in understanding the required rules and regulations that apply to their project and to reveal potential problems. The goal of providing a pre-application meeting is to make the permitting process as efficient and understandable as possible. These meetings are typically optional. If the applicant chooses to utilize this process, there is a separate fee that must be paid prior the meeting.

Step 6: Review by Staff

Department of Planning & Building staff reviews the application for consistency with applicable map act and subdivision regulations and the California Environmental Quality Act (CEQA).

Step 7: Schedule Hearing

Staff schedules the application for a public hearing - either a Subdivision Review Board, or Planning Commission based on the subdivision entitlement type.

Step 8: Reach Decision

During the public hearing, the hearing body considers the application and reaches a decision to either approve, conditionally approve, or deny the application.

Step 9: Appeal Decision (Optional)

Any aggrieved person can appeal a decision to the Board of Supervisors. Projects located within the Coastal Zone can be appealed to (or by) the California Coastal Commission.

Step 10: Record Subdivision

The applicant must record the approved subdivision within two years of its approval date.

Step 11: Extend Approval (Optional)

The applicant may request a time extension, in writing, to extend the approval date for one year. The maximum number of available time extensions is based on the subdivision entitlement type.

The owner of the subject property or anyone who is given consent by the owner of the subject property may use this service.

Please refer to the Department of Planning & Building Fee Schedule for application fees.
