Ya gotta be careful with terminology in Sun City. There IS an "HOA", and membership is voluntary at 20 bucks annually. However... there is also the Sun City Association dues of around 450 bucks per household that is mandatory. That allows for two people residing in that residence access to the Sun City amenities... like pools, spas, weight rooms, etc.
Now... here's the rip off.... if an individual owns two or more properties within Sun City, he STILL only receives two membership cards (for the first household)... yet pays the dues on EVERY property he owns... while receiving NOTHING in return for those dues.
The board needs to address that.
