There are several Sun City subdivisions, in Oro Valley, Rancho Vistoso, specifically. As a long-time resident of Oro Valley (since 1974), I can tell you that I am unaware of any Sun City subdivision that does not have a HOA governing the subdivision. That said, the HOA fees are directly relational to the specific Sun City subdivision. There are over 10 subdivisions in Sun City, so please feel free to reach out directly to me at email@example.com or call me at (520) 481-7443 and I can provide you specific information in this regard.
I trust you will have a fantastic day!
