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

addr:street and addr:housenumber to every object that reasonably has a unit number (so no sheds) for starters. There are a few possible configurations where you could reasonably interpolate unit numbers - eg. situated in a line, or side by side around a turning point - as long as you definitely know at least two. I don't think anyone would hunt you down for interpolating precise numbers in reasonable to obvious cases, but if you want to be sure, there is addr:interpolation (see also https://wiki.openstreetmap.org/wiki/Key:addr:*#Tags_for_interpolation_ways)

If you really have no clue, or reason to believe that the numbering are not regular, I'd leave a note on the site - or add a fixme tag - or both.
