Does a building get a new number if it is is built on a plot with am existing building? Or do the two neighbouring buildings (the old and the newly built) share a stand number? Are stand numbers only unique within a city or a borough? There is something similar in Germany (and other European countries as well). A lot of smaller villages do not have street names. When a building is built, the local authorities assign the next free number. Only buildings in the centre of these villages seem to have ordered number because they got their numbers en bloc when addresses were introduced. These numbers are only unique within the village. The name of the village is used as street name in postal addresses in these cases and addr:place used instead of addr:street. It looks to me that addr:housenumber=<stand number> + addr:place=<name of city/borough> is a valid tagging in your case. > *If its to associate a particular plot code with a building or plot then > could you just add a tag to the existing building?* > Yes this is an option.

It looks easier but it bears the risk that you mess up data by automatically editing it. Don't underestimate the conflation of existing OSM data with your data. In addition, an import should not replace existing geometries in OSM by new objects just because it is "easier". Instead, the existing geometries should be modified to preserve their history. > *Do you want to map the plots independently of the buildings?* > This is another option since the plots are different from the buildings as > John has pointed out.

Did you get familiar with OSM in the past by doing some mapping in OSM in the area where you live and/or which you know well, e.g. adding points of interest or enhancing the map with local knowledge? It helps one to understand how OSM works, how the data looks like, how good the data is and what to do if things go wrong. I think that people on this list can give concrete advice if you write down your plan on a wiki page as others imports do.
