Submitting an Application

A ministerial review must be submitted for review to the Planning & Community Preservation Department prior to submitting for a Building Permit as part of the Plan Check Process to ensure compliance with the zoning regulations.

The Master Zoning Application is necessary to submit for any project in Sierra Madre requiring zoning clearance. The Accessory Dwelling Unit Submittal Checklist provides an itemized list of material to submit with the Master Zoning Application to begin review of the project.
