I live in Salt Lake City, Utah. We have under 1/3 acre. The backyard is fully fenced. We also have chickens in a coop with a fenced "chicken run." There is room in the yard to set up something for the ducks. When winter hits, the ducks will need to be outside (unless it is SUPER cold, then they will come into the garage). We don't have a pond, but plan on using plastic kiddie pools. We also don't want to spend a lot to build them a home.
