We rent a huge 2 level apartment in a 100 year old home that's been broken into four units total. Our landlord is a very laid back guy and is fully aware of the snakes and rodents we keep. Our agreement with him is that we will ensure as best we can that no escapes occur and our hobby does not bother our neighbours. Over the 2 years we've rented here the landlord has had far, far more trouble with our neighbours and their dogs or parties or illegal activities. I think our quiet family, even though we keep a lot of snakes, is easy for them.
