Renter not Household Member

I am a single man, renting a room in my sister's house. My address obviously is the same as hers and my last name (she chose to keep her last name upon marrying) is the same as her last name.

Because of this, I was considered a member of her house hold and so I denied coupons. What can I do?

They count landlord-managed apartments separately, not household room rentals. Contact other family members in the extended family or friends to get coupons mailed to them.
