Hi John, You can get New York tax parcel maps inexpensively ($300 per Borough) and information needed to link it to addresses for free (I don't know if the licensing is consistent with OSM). My guess is www.ridethecity.com has licensed the parcel data and has created address points from it. The city may approve the creation of an address point layer based on this information that would work with OSM, but then again, maybe not. Here is the relevant link to the data: http://www.nyc.gov/html/dcp/html/bytes/applbyte.shtml
Lots of the municipalities in the GVRD have released their parcel maps, some which may include addresses, but not others. As part of its "Property Information Package" the City of Vancouver provides address data (with duplicate addresses removed) that appear to be assessor parcel centroids. I don't know what the thinking is about the consistency of the City of Vancouver's licensing with OSM, but it may well be consistent. The link to this data is: http://data.vancouver.ca/datacatalogue/index.htm The general issue in terms of importing address points is that the data generally comes from local governments (generally cities in Canada and counties in the US), and local governments differ widely in their data availability, data field formats, licensing, and basic availability.

Hey! So I'm trying to figure out the street address thing. Some POI's have street addresses. Some nodes in buildings have street addresses. Some cities have more address data (Paris and Denver come to mind), some have nearly none (New York). If I had to guess I would say less than 1% of POI's/Building have address data (US Wide) and I suspect Europe isn't much further ahead (10%?) Some cities have addr:interpolation. Toronto is an amazing example (thanks CanVec and the people who imported the data): http://osm.org/go/ZX6DTTVf9-- So I was looking at http://www.ridethecity.com/ . They seem to have street addresses for New York and Vancouver, cities that seem to have poor address info in the main data. Am I missing something? Is there another file besides the plant.osm that has addresses? Thanks for the info.
