Are you renting a single-family house, an apartment in a multi-family, or a unit in a building/complex?

If you are in a SFH, it's probably on you. If you are in a multi-family house, the LL should be taking care of it, but may not realize they are supposed to depending on how experienced they are.

(Based on the fact that you say your lease doesn't specify, I am guessing you are not in a complex because they would know the laws)

​

Thank you
