As-Salamu 'Alaykum Ustadh. My brother owns a building and asked me to clean it before a youth welfare organization in Germany inspects it. They provide residential care and support for children and teens with mental health or social difficulties. Is it okay for me to help?

Yes, it is okay for you to help as long as this is not deception. If you try to show them something that is not the reality, then this is not allowed.
