You always need a sim in the business owning household. Because the business is owned by the entire household. So you have your sim and his roommate, by the game mechanics they are both owners of the business because they are considered a household. Should your sim die (just for example) then the roommate would be the sole owner, unless you have expanded the household.

Okay. How to make my sim was not unemployed from his business?
