Living Options for Past Drug Addict Brother

Hello, my brother has been a drug addict for 20 years (opioids) but currently clean, but like all addicts, this is always a slippery slope. From the years of drug use he’s developed some schizophrenia symptoms, which have been diagnosed. He lives in out of state and my parents are considering moving him out here. They have a small two bedroom condo so taking him in/supporting him won’t work. Does anyone know of locations in this area (doesn’t have to be Skokie) that could work for an adult trying to get back on his feet like this? Not necessarily a halfway house if we can avoid but understood that might be the only option. Please let me know if you know of any locations.
