...What is this "side yard" of which you speak?
Side yards are not a thing I have any experience with, and definitely are not something I have given much (if any) thought to. Like, ever.
I didn't even have a side yard at our house in NYC (or, I guess I kind of did because there was a space between our house and the house next to us, but it consisted largely of a spricket-and-poison-ivy-infested wasteland. Then I moved out to the California suburbs, and everyone here seems to have a pair of functional side yards. We have neighbors who use the long, narrow spaces that run along the edges of their houses for storage, as dog runs, to hold chicken coops, as play spaces for their kids - all kinds of things.
