Alternate Process for Nonstandard ePlans

If there is a plan review required for your permit type, you will need to apply for a second permit for “Plan Review Only.” This will allow us to receive your plans electronically. 

Examples of permits that require a Plan Review Only permit in addition to the permit to complete the work include an addition to a single-family home, a detached accessory structure, or a deck. Please follow these steps carefully to complete the process.

No fee is required for the Plan Review Only permit application. This application serves only to provide access to electronic plan submission for permit types without Standard ePlans configurations.  If you are asked to pay a second fee, the ePlan review only permit was not processed correctly.  Please do not pay the second fee. Contact the Customer and Technical Support Center to void the application that was incorrectly processed and try the process again.



Log in to the FIDO System

It is critical that you log in to the FIDO System before you begin this process. Failure to log in first will cause the system to change your permit type to one that generates fees. This error will require you to start the process over to create the right permit type.

The example shown below is for residential, but the same process applies for commercial permits.  Select “Commercial ePlan” if you are submitting a commercial project plan.

Apply for a permit for “Plan Review Only

After you have logged in, select the appropriate “Plan Review Only” permit type from the bottom drop-down menu – either Residential ePlan or Commercial ePlan.

FIDO New Permit Application Screen


Enter Occupancy Type and Work Type

When you reach this point in the application process for your "Plan Review Only" permit, select a work type of “NEW SINGLE FAMILY DWELLING” for all residential permits or “NEW COMMERCIAL BUILDING” for all commercial permits. This work type establishes a plan review routing process. You must select one of the two plan review work types regardless of the actual work to be performed. Remember that this second permit is only for the purposes of Plan Review. Be sure to fill in all required fields marked with an asterisk. See Step 4 for specifics on Job Description.

Job Description

You must enter the Job Description exactly as follows: “PLAN REVIEW ONLY FOR PERMIT [FILL IN THE PERMIT NUMBER OF YOUR PREVIOUS PERMIT APPLICATION FOR THE ACTUAL SCOPE OF WORK HERE].” This allows staff to associate your plan review with the permit for the actual scope of work. Please continue with the steps below. Once submitted, a permit technician will link your Plan Review Only permit to your original permit.

Stay logged into FIDO and go to “Status of Applied Permits.” Select the “Upload ePlan” button. That will begin the workflow in ProjectDox.
