► Permits in Fairfax County are processed using FIDO, our online permitting system.
► ePlans are uploaded and reviewed using ProjectDox.
The two systems are independent and require separate logins. The process to create accounts for each system is provided below.
Once you have established a FIDO account, log in and apply for the appropriate Permit Type. At this stage you will apply for your permit based on the type of work you wish to perform.
You must pay the permit filing fee prior to submitting your ePlans. Check the box of the permit with an unpaid fee status and click the “Pay” button at the bottom of the screen. The fee can be paid with a check or credit card through the county's secure payment site.
If you are applying for any permit other than New Single Family Dwelling, Interior Alterations Commercial or New Commercial Building, go to the Alternate Process for Non-Standard ePlans page for further instructions.
Once you have completed the payment process, return to the permit status page. (You may need to refresh this page to update the payment status.)
Once the payment is processed, you will see a link to upload the ePlan in the far-right column. Click “Upload an ePlan” to begin an electronic plan submission request for ProjectDox.
Confirm that your email, permit number and other project information is correct. Then check the box beside “Are you sure that you are going to submit a plan/plans electronically for the above permit?” and select the “Submit” button. This will create a ProjectDox workspace for your project.
You will receive an email with an invitation to ProjectDox for your permit application within 15 minutes. The invitation will contain instructions and log in information.
Once you are in the ProjectDox application, you will be able to Upload ePlans.
