At least in all of the US suburbs I've lived, there's been free tennis courts and a variety of other courts all over the city. The high school down the street from me has 4 tennis courts. I hear them being used all the time when I'm on a walk (incidentally, along a greenway with a shared use walking/bike trail that wraps around the school grounds and connects via a tunnel under a highway to the rest of the city bike trail system).
