I think the building you are referring to was a building that housed a business for washing and drying clothes.
I lived in many different Chapel Hill/Carrboro places back in the day and challenge folks to match or surpass my record:
1) Ruffin Dorm
2)Kingswood Apts
3)University Garden Apts
4) double wide at the top of Wave Road
5)Park and Stay Trailer Park
6)Estes Park Apts
7)trailer park on Airport Road (can't remember the name)
8)house on Barclay Road
9) house on Justice Street
10)Apt under a house on MT Carmel Church Road
11)Gatewood Apts
12)duplex on Hillsborough in Carrboro
13)Sharon Heights Apts
14) house at Starpoint
And since 1982 I have lived in two homes in Carrboro as a semi-responsible adult with my wife and family
