I am unable to adopt from a rescue that I work with at my job because I don't vaccinate yearly, so my pets aren't "up to date on vaccines" - even a letter from my vet and titer records did not help the situation. Another breed-specific rescue wouldn't adopt to me because I live in a duplex, so there is a "shared wall". Disregarding the fact that each side of the duplex has its own, seperate, fenced-in yard, and that we each OWN our own houses - there is no housing association, there is no landlord, etc. It's just like owning a single family home except for the fact that they're smooshed together. That being said, I love the fact that the rescue I work with does pretty much everything on a case-by-case basis - every dog is different, there are no blanket rules that will fit every one of them. Yes, that crabby old Chihuahua might need a home without children, but the big friendly Lab mix would be excellent with children. And adopters are evaluated on a case-by-case basis as well. As long as you have a good, safe way to exercise your dog, then who cares if you have a fence or not?
