Little House On Washington Road

I've always wondered about the little house nestled between the North Parking Garage and H&R Block on Washington Road. As far back as I can remember, this house has had its windows covered and nothing going on inside.

Does anyone know the history of this house and why it just sits there unoccupied? It looks as though it used to be open for business since it has stickers for credit cards and a Yellow Pages ad on the front door. What type of business was it and how long was it in operation?
