Old portal account issue | Existing customer did not re-register after the 2024 system upgrade. | Re-register using the current email address on file. |
Wrong project type | The selected application route does not match the work. | Use Online Services Help and call the Permit Center if unsure. |
Missing Building and Fire Permit Application | Required application was not uploaded for building/fire permits. | Download and upload the current Building and Fire Permit Application. |
Incomplete plans or checklists | Plan review cannot confirm code compliance. | Use project-specific plan review checklists before submission. |
Planning or engineering review required | Zoning, public works, fire or land development review may be needed. | Confirm all department reviews before assuming a simple building permit. |
