Imagine caring that your neighbors have pinker shutters or don't have curtains? Imagine caring enough to fine them until they either comply or have to move out?
Yup. My parents live in an HOA that used to have a woman (who had no official capacity with the HOA other than living in it) drive around in her golf cart every day with a clipboard to note down any violations she spotted. One of her favorite rules to enforce was one that indicated how long you could have your garage door open for (something like 20 mins). Like another commenter's experience above, she too had a ruler she would use to measure various shrubs etc. in hopes of finding a violation.
not a fan of fighting back, but you need to fight back against these type of people.
i would report suspicious activity both to the HOA board and the police. let’s see how they handle this.
