[Info] I just learned that nearly all of the counties in the US offer a GIS map for property information look up. I've been using it to add correct addresses to unlabeled new/existing buildings. (lemmy.world)

A few key phrases to help you find your county of choice are: Assessor's lot map, Assessor's Parcel map, County Property Viewer.

Just add the name of the county you need info from, plus one of the key phrases, and bam. You're in business.

Hope that helped someone else.

Most of them with compatible license should be already imported, so there is a huge chance OP's changes will be reverted as soon as someone notices from the local community.

Afaik most communication between US mappers are happening on the osm us slack, other ways of contacting them are listed on their website: https://openstreetmap.us/

    The houses on my street/surrounding area are only listed as an address range covering the whole block instead of individual addresses for each house. I've been tempted to fix it for my house, but I stopped each time because I know the "right way" is to do it in bulk.

    I'd love to have more info/guidance about how to accomplish that (ideally without having to talk to people on Slack).

    Osm is a community project, so some communication and coordination is necessary. Most active mappers usually follow multiple channels, so if you find some more fitting way just try it there (e.g. I'm subscribed to the local mailing list and osm forum local topics and I read the local matrix room).

    You can find your local communities with this map: https://openstreetmap.community/

    Osm US doesn't have a mailing list, but you can use the osm forum with your regular osm account, so you don't have to register there again.

    Imports usually consider existing, already mapped features, so your surveys wouldn't be lost. It's possible that it would take years to get the official data, so it can be a shortcut to add some addresses manually. Official sources can be wrong as well, here we got some speed limit data from a road maintenance company, but we have to report back a lot of discrepancies based on surveys and mapillary... They thank our efforts at least.

    The easiest way would be to ask why it's not imported yet, without it we can only guess.
