It's a bit unusual in this case because the episode was delayed by a season. But, yeah, it usually take a good year or so from concept to completion. I recall Jayson Theissan mentioning at some point that during season one they were working on all episodes simultaneously through the entire production cycle running up to the airdate. It's a lot of freaking work.
It's a good thing that it's also a labor of love, or I don't know how they would handle all of that stress!
