Hmmm.  Looking more closely at the changeset which added this info, sources are given which I would not expect to include housenumbers and addresses.
The import which was not done as an import has further problems, like excess precision in the height field.  I would not use more than a single decimal digit, for inaccuracy the width of a hand tops.  With a good source I'd accept centimetre accuracy, even if impractical.  If heights are from LIDAR, I've no idea what margin of error there might be.  I'd guess a coarse fraction of a metre based on my ignorance, but would be happy to be proven wrong.
However looking at a few of the nearby buildings in the raw data (not in background aerials) I somehow have my doubts, seeing a building part as less than 3m, and many at just above, which does not leave much roof structure.  Then again my background is that the typical house near me is on the order of 10 metres with three stories, at least a metre sacrificed to the snow deities.
.
Feeding Baldwin lane into a text search gives me postal results that match the format of the added data.  But I note that on neither Quail Ridge as you pointed out, nor Baldwin, were housenumbers or streetnames added to the buildings.
I do get a single google text search Quail Drive housenumber returned, that does not match the Blue Mountain numbering.  But also Quail Ridge Lane hits, no doubt elsewhere.
If a drive is named, and especially if it is used as postal address, I would tend to keep it after seeing what sort of text search hits make use of it.
Poverty Lane here, however, appears to be in error, duplicating a more fuller road to the west and contradicting the housenumber info here.
I am tempted yet hesitant to ask in a changeset comment what is the source of the address info, because it obviously does not match OSM import standards, and unless my countries are mixed up, I believe the Post as a source here is not allowed.  However it would be great to hear it came from a public domain source as well as to clarify missing address info to the nor'east and east o' here.
