How do I obtain information on starting a care facility in my home.

Since you will have to be licensed by your state (if you are in the US) start with your state.gov website. Many times the requirements are online. You can call around locally, your town social worker, visiting nurse association.
It won't be cheap to have the proper ramps, size doors, fire protection, emergency lighting, and so on.
