In this crazy world, you can repair but not replace doors and windows without notifying building control. When I had a good discussion with BC on what exactly a repair was, we ended up agreeing that if any of the original remained it was a repair, we also agreed it didn’t have to be a specific minimum size.
You can also remake a frame hang the old door, build a new door and fit that to the the new frame. That’s is also I understand a repair. No specified time for the old door to remain in place……well long enough for a photo
