- Submit the complete application package to the City. Vernon publishes both the EnerGov portal and an instruction to submit complete application packages to the Planning Division at City Hall, so submission appears to be hybrid depending on permit or review type.

- Wait for completeness review and staff routing. Vernon states State law allows 30 days to review an application for completeness, after which the application is scheduled for Project Review Committee review; Level A and B matters are staff-level, while Level C matters proceed to City Council with mailed notice to surrounding owners and a 30-day appeal period after final review.

- Pay permit and plan-check fees, then obtain the permit before starting work. Vernon's fee schedule states permit fees are valuation-based and that work started before permit issuance is charged an additional fee equal to the permit fee.
