Conventions for House Addresses (sh.itjust.works)

Hey guys, I know this question is probably answered somewhere on the internet but I just can't seem to find it.

In OSM, I have an address, and on that block of land I have many separate small houses, each with the same house number, but different unit/flat numbers. I could assign housenumber 123 to each but from what I understand, duplicating information is bad.

Is it a good idea to instead omit this information from each house, and draw an area around the entire block with addr tags on that specifying housenumber, suburb, street etc. and each actual house only has unit number and building type?

Thanks guys

Hi,

Addresses can be really complicated. The full guide is on the wiki: https://wiki.openstreetmap.org/wiki/Addresses

Personally, I would open up JOSM, select all the buildings and slap addr:street and addr:housenumber=123on them. However, I would add addr:unit=XYZ on every one of them (as @Krzyzwen@feddit.de pointed out as well).

Next question: does every single house have their own letterbox? Or is there one location where all the letterboxes are located? Add a https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dletter_box with addr:street and addr:housenumber as well!

I don't think that adding an address to the plot of land is very useful (but a name of the project/area might be nice as well). Have a look at https://wiki.openstreetmap.org/wiki/Key:place for this, place=plot or place=city_block might be appropriate depending on the situation.
