Permit history for parcels is via the Parcel Viewer map
On the site, search for various properties via any of the options available. You can use address, owner, map/parcel, etc.
Once opened, click the map/parcel link. The map will change zeroing in on the property. In Parcel Viewer options on the left, select Permit History. That will open the listing of permits for the given property. Click the permit number link and ePAV should launch. When the list opens, click the link (if one is listed) to open the document.
After looking at the image, close it, close the result list, and return to the permit listing. At the top, there is a button to view all records for a given property. Click this button and a new list should appear. Click one of the links to open a document.
