I am trying to map the addresses of apartment and condo units that have one street address (house number) but many buildings with different unit\apartment numbers. As an example say a apartment complex has an address of "5 Example Address Lane Arlington, Virginia 22207" with 30 small condo buildings each having and apartment\unit number so for example unit number 15 would have an address of "5 Example Address Lane APT 15 Arlington, Virginia 22207". How do you add this unit number to the address? asked 20 Dec '14, 08:00  Luke S |
One Answer:
See https://wiki.openstreetmap.org/wiki/Key:addr addr:unit seems to be fairly popular. answered 20 Dec '14, 10:25  SimonPoole ♦ |
Thanks SimonPoole, how do I use this properly, do I add one addr:unit property and separate each unit with a comma? For example addr:unit=1a,1b,2a,2b,3a,3b? Should I put the addr:housenumber as the street number also?
IMHO if the units are separate building I would tag the full address (including "housenumber" and unit) on the buidlings. If there is more than one unit to a building, I would add one address and list the units in the tag: addr:unit=1,2,3,4 ...
I think addr:flats is used to list a range of apartments/units in a building, while addr:unit gives a particular apartment/unit. If you area listing individual addresses in a building, those are typically done with nodes within the building footprint. See https://wiki.openstreetmap.org/wiki/Key:addr#Detailed_subkeys
addr:flats=3-7;10;14;16-18from Key:addr:flats
"For example a house at '10 Some Street' converted into 3 flats with postal addresses of '10 Some Street', 'Flat 1, 10 Some Street' and 'Flat 2, 10 Some Street' can be tagged
addr:flats=;1-2 and addr:housenumber=10"
