I imagine the church updates info (at least in the United States) pretty quickly. The USPS needs to know how to deliver mail, so their databases are usually pretty good (although I think it's all resold through other vendors and it depends how frequently the church's vendor provides updates).
My problem is that maps don't necessarily get updated that quickly. I've found MapQuest is usually on top of new addresses more quickly than Google, and since the Ward Map uses Google Maps, it might lag behind. I've had a family be "unmapped" on the ward map for a while because it doesn't know the exact address (it does know where the street is). If I go to conventional Google Maps and look at the street, it doesn't show there are any houses on it yet (so I'm not totally sure where to manually put the pin if I manually set it). But I suspect that's a problem with Google's data provider and the church can't do anything about it.
