How do I tell iOS 7 which address is my “home” address? In iOS 7, if you bring up the Notification Center in some circumstances it will tell you, “Right now, it would take you 18 minutes to drive home.” I recently moved and the address that iOS 7 has set as “home” is now incorrect, but I still want to include the old address in my contact card. How do I inform Siri (and the rest of the system) that my “home” address has changed?
This should do the trick:


Edit your contact card on your phone (in the Contacts application);
Change the label of your old address to anything you want;
Set the label of your new address to "home"
