Sorry, no. The BLM dataset I use for that layer only has public land boundaries in it, not private parcel data. Public land is color-coded by management agency (key appears under the layer when you check it, and at the top right of the map viewer), but I don't even have the boundary lines for private parcels, much less ownership info.
Because land records are generally managed at the county level in the US, collecting data from each county and rolling it into a seamless nationwide dataset is incredibly labor intensive, and therefore expensive. Figuring out if I can license the data from someone who's already built out a dataset is something I'd like to tackle at some point, but it's definitely a long-term objective and not a near-term one.
It looks like MyTopo uses Trimble Terrain Navigator Pro for this data, since MyTopo is part of Trimble. I suppose the pricing makes it impractical. There seem to be several companies offering this service, but again there are licensing costs and type-of-usage issues.
I just tried a simple lookup on the Inyo County Assessor's site, making it as easy as possible (I supplied the APN) and it gave me a "please wait" spinner for > 10 minutes before I gave up.
So, this seems to be a good deal more complex than I thought when I asked the question. Thanks for your response!
