A family and a home

My brother has his family of six to support him, as well as disability housing where he lives now. There are challenges, but our parents have worked hard to get him living on his own. He struggles on his own, as he often does not let the person we hire to come in and clean his apartment. I think he desires a feeling of autonomy, which I completely understand. The question is how to help him maintain his apartment in a healthy way.
