I did a quick search, and found a summary which does indeed *imply* that you may consume alcohol at your place of residence. (What the summary actually said was that you could contact it - I didn't read the actual law).
However, if you are planning to use this as a defense with regards to your other post, there are some problems with that. First, your post says you and your friend "went out" and did some drinking, not that you were at home. Second, even if you were at your place of residence, only one of you would have been at home - so the other one was breaking the law no matter how you cut it. Finally, the fact that you *may* be able to legally drink while you're at home has no bearing on your stealing a stop sign.
