The homeowners association (Kingwood Place) keeps sending me letters about trash bins in view on days other than trash days. Going so far as threatening legal action. Can someone tell me what the rules are so I can stop their harassment? 

Call your HOA,

Get your trash company info, and inquire there.

Hopefully this is helpful... 

Most (if not all) villages in KW have rules about not having trash containers in plain sight other than trash pick up days. If you ignore the warning letters long enough, fines and even legal action are typically written into the HOA rules and bylaws as courses of action. 

You cant have your trash cans visible from the street on non trash days.
