  1. Pre-application meeting with Planning Division to review site, code constraints, and submittal requirements.
  2. Prepare application package: site plan, elevations, RF emissions report, structural analysis, and visual simulations.
  3. Submit CUP application and environmental checklist to Planning; application completeness review begins.
  4. Public notice and hearing before the Planning Commission or decision by staff as allowed by code.
  5. If approved, obtain Building & Safety permits for construction and any required encroachment permits.
  6. Pay any fees and post bonds as required by conditions of approval.

Community notice and an opportunity to appeal are standard parts of CUP proceedings.
