You're free to not live in a neighborhood that has one.
You can bet this guy signed the HOA agreement when he purchased the home.
Exactly. You knew moving in there’s a HOA and probably had to sign for the HOA rules or by-laws. Don’t like it (and I don’t), don’t live in an HOA, or follow the rules and vote in new leadership.
I never have and never will live somewhere with an HOA, nor sign any ‘agreement’ with one.
