Carefully read your local law (in Texas it is called property code). There are requirement when HOA fine an owner. In many cases, they can not follow all of the requirements.
And collect evidence if the HOA fine you and not fine other owner for similar situation. You just need one case, you can complain to federal fair housing agency for discrimination and it is federal crime.
