Hi, I am currently looking for an apartment to rent in California and I came across an apartment complex that is pet-friendly. In the ad, it listed the refundable apartment deposit ($400), the refundable pet deposit ($500), the additional pet rent ($45) and then a non-refundable pet fee ($500). This is the first I've come across something like this. I've never heard of an additional non-refundable pet fee, and such a high one at that! Is that legal in the state of California? I tried looking online, but couldn't find anything about it (just pet deposits). Thanks!!
