Nothing works for me so far.

\d{1,4}( \w+){1,5}, (.*), ( \w+){1,5}, (AZ|CA|CO|NH), [0-9]{5}(-[0-9]{4})?

In this regex, you have one too many spaces (before ( \w+){1,5}, which already begins with one). Removing it, it matches your example.

I don't think you can assume that a "unit 123" or similar will be there, or there might be several ones (e.g. "building A, apt 3"). Note that in your initial regex, the . might match , which could lead to very long (and unwanted) matches. You should probably accept several such groups with a limitation on the number (e.g. replace , (.*) with something like (, [^,]{1,20}){0,5}.

In any case, you will probably never get something 100% accurate that will accept any variation people might throw at them. Do lots of tests! Good luck.
