We're renting a house. Our landlord, quite amazingly, did not care that we were moving 50 snakes into the basement, and even more amazingly, was also ok with the 2 rodent racks, so long as they were escape-proof. On the other hand, this place is not exactly 'to code', either, lol.
I do not anticipate ever finding another guy willing to let us keep all of this in his house, so we'll have to stick to this until we can afford to buy.
It's always worth asking, though!
