The simple fact is that when you sign a CONTRACT [aka the HOA agreement], you are agreeing to abide by the laws now and in the future as long as you live there.
The rules are changing contants in most HOAs. If you can’t handle it, leave.
Wait a minute—who are you aiming this at? I served on the board of directors of our HOA and chaired the committee that controls community appearance. I also rewrote the “guidelines” (= rules) for maintenance and appearance.
But I insist that it’s a true injustice when petty-minded, envious people who have nothing else to do with their lives say, “Hm, I don’t like the type of bushes those homeowners installed. Let’s rewrite the rules to accord with my tastes, then use the multi-hundred-thousand-dollar budget of the HOA to torment the homeowner into submission to my desires.” Or, alternately, “I don’t like that neighbor, so I’m going to use the legal firm of the HOA to make his life difficult.”
Remember, when you sign a contract in the business world, one side can’t suddenly change the terms of the contract.
