In short: land covenants. In HOAs you will see titles containing terms about the property being subject to restrictions voted for/applied by the association. If you continually decline to adhere to the restrictions, you can be legally compelled to sell and move on. Note: I'm using phrasing local to me, I expect there may be minor differences but the same gist.
