Hi andyblueg, 

Unfortunately, the current routing/navigation systems for pedestrians are not so advanced that they understand where the most sensible route to the entrance to a building is.
This is particularly unsuitable for blind and disabled people.
For this reason, the guidelines mentioned above also recommend always creating a footpath to the building entrance.
As an example you can see here https://graphhopper.com/maps/?point=54.078009%2C13.40443&point=54.07744%2C13.404873&profile=foot&layer=Omniscale

Best regards, DP
