@SnipSnip: In the link I provided, this is what it said:
If You Have Purchased Your House Before the HOA was Formed
If you have already purchased your house before the HOA was formed, you can refuse to join the HOA because you did not and have not signed any document consenting to the association. And since no one should be forced to sign a contract, you can choose to sign the contract and join or refuse to join.
However, it is important to note that this method of refusal can be very tricky. If you must use this means to refuse to join the newly formed HOA in your area, you must ensure you did not sign any paper stipulating that the community can have HOA in the future.
If when purchasing your house, you signed a document that makes the availability of HOA in the future for the community. You have already given your consent and must join because the paper you signed states that the community can have HOA in the future.
If you are sure that the papers you signed do not have the term “HOA” on them, you’re good to go.
