Butting a new cmu wall up against an older wall

The load supporting walls for an addition will be perpendicular to and will butt against an existing load-bearing cinder block wall. I suspect that I shouldn't backfit a rigid connect between the two walls since they will settle, expand, and contract differently. Does anyone have some general advice or know of any sites that discuss the issue in depth or names of products? I have seen a steel flex joint in commercial construction, but don't know if this is overkill for residential. I am not in an earthquake zone, but we've had as high as a 3.something in my lifetime.

Contact your local building department, and see if they require any type of bond between the new and old walls. I suspect as a minimum they will want the new and old footings doweled together, and possibly a few ties at set course intervals at the walls' junction.
