    Monitor your email and your application in the Public Health Permit Center, responding to any questions or comments from your plan reviewer. Once the plans have been stamped and approved, the Plans Examiner will email the approval letter and supporting documents to you.

    Note: Due to current application volumes, it may take up to 4-6 weeks for a Plan Reviewer to complete an initial review.

  • Submit the application to operate and pay your operating fee in the Public Health Permit Center

    Using the information from your approval letter, apply for and submit an operating permit application and pay the operating fee in the Public Health Permit Center.

    The operating permit fee is separate from the Plan Review fee that was initially paid when the equipment floor plans, equipment list, menu and documents were submitted.
