The check for zipcode seems to be the cause of the problem. My work-around is to add a dummy '00000' zipcode to the input. Perhaps a future version could include a zip=None option?

In [38]: ap.parse_address('51691 North Scottsdale Road, 00000')
Out[38]: Address - House number: 51691 Prefix: N. Street: Scottsdale Suffix: Rd. Apartment: None City,State,Zip: None, None 00000
