According with newmoonmovie.org, the filming is now happening on Jacob’s house:

I went by Jake’s house last night to see if I could get a few pics of Bella’s truck for my collection and they were full on filming there! I got to see Taylor and Kristen standing in black rain jackets being talked to a few of the set guys and the guy who plays Billy Black (Birmingham?) walking around in a white, blue and black polar fleece with his signature hat. I couldent snap any pics because the set was guarded by POLICE!!! They blocked off all of [redacted] and part of [redacted] in [redacted] for this but seeing that the set is on the corner of the cross streets I was able to slow down to look.
