This is the parcel footprint of "1011 Silliman St" which includes parcels 5935-027 and 5935-028.
To see this live go to http://eas.sfgov.org.EAS originally did not support this but we changed EAS when we found these data in AVS. Parcel 5935-028 is not spatially coincident with the address point (in green).
You can see this for yourself in EAS.
Acella does not support this sort of address.
In Acella, parcels for an address must be spatially coincident with the address point.
