SDA is a house that has been designed for people with very high needs or extreme functional impairment. The aim of an SDA is to make accessing supports easier.
SDA usually involves a shared home with a small number of people. You may be able to get an SDA by yourself if that option is right for you and your needs. SDA funding includes the cost of the house you live in. You will still need to pay rent and/or personal costs to live in the SD. The SDA funding does not include service or supports that you might get when you go into your home.
