The buildings you mapped as not square in fact are. There is an imagery anomaly toward the north of this changeset which distorts their true shape. In situations where a feature may be distorted, hard to see or obscured I recommend using multiple imagery sources. You can offset the alternative imagery to the reference. If you use this method you can even map using the alternate imagery so long as the same feature exists in the reference.

Some of the building footprints are inaccurate. Use areas of high contrast along the edge of roofs to determine a buildings shape and orientation. Map the building using its corners. If the image is distorted you may decide to map say, a 4 cornered building based on only 3 or maybe  2 of its corners. Use your judgment to decide which corners you will reference.
