It is usually the side that faces the street, although it can also be the other side. If the other side confronts the ocean, a river, or deep water, that side is sometimes considered the front. Also, the side closer to the intersection of two streets is generally considered the front. There are several ways to tell if a house has been reversed. The easiest way is to look at its street address: if one reads across from left to right, starting with the lower number, then the opposite side of the house will have those same numbers but in reverse order (for example, 88-44-22). Sometimes they're even painted different colors to help people remember which is which. Another way to know for sure is to walk up to the house and look inside a window. If you see what looks like the living room on the first floor while the second floor appears to be missing, then the house was not reversed. On the other hand, if you see what looks like the second floor in a downstairs apartment, then the house was reversed when it was built. Still another way to identify a reversed house is by looking at its city block number. This number is printed on mailboxes located near the intersection of Main Street and Calumet Avenue in South Braddock, Pennsylvania.
