The pop star sued several companies that designed and inspected a home she bought in 2009.
The singer claims a balcony in the house lacks the proper slope and was the reason water leaked into several rooms.
The suit states the damage left the home uninhabitable.
Rihanna said if she had known about the problems, she would not have paid nearly $7 million for it.
She claims Landmark Design Group, which remodeled the home, has failed to make necessary repairs.
