Still annoyed at the landlord

It has become more evident that, now that the original lease has expired, the only law our landlord broke was violating our lease by not replacing our fridge as per our estoppel agreement (the thing she and we signed that said she's the new owner but our lease is the same and she has to do anything the old landlord left behind, like replacing our fridge).

The new offer/new lease is shakier because our documentation isn't that great, because our landlord evades the "can we get that in writing?" question, a lot.

So basically, except that one big contractual obligation, which she technically isn't obliged to fulfill anymore since she evaded her responsibility to it, she isn't breaking any fair housing laws anymore.

I've emailed the Rent Board anyway. Maybe there's a hidden Socialist State of Berkeley clause I don't know about, like Section 14, Subclause 2: Being Professional; or Section 12, Subclause 13: Taking Responsibility; or Section 8, Subclause 85: Doing the Right Thing in a Timely Manner, Like, Last Year.
