Tongue in cheek answer(s): Ryoga lives in a) his tent, b) Akane's bedroom, c) see map in manga....
Seriously, it's never stated in the manga, and the only clue we have is the awful map Ryoga had, so his house could be pretty much anywhere. Nerima is huge, with over one million people living there, and the neighboring wards aren't all that much smaller. Technically there's no problem with it being in Nerima aside from the logic fault that is Genma not making a stop at the Saotome house if he was that close to home anyway, but then we *are* talking about Genma (and Nodoka!)...
Cheers!
