Hypothetical question

On mobile so apologies for formatting. Fwiw i've been trying to resolve this on my own but I'm stuck.

lease says no pets but ESA rights. I've been dealing with this for about 9 months now and teh situation isn't improving.

I have been in this property for 8 years. My monthly rent is $3,238. We are on a month-to-month now sadly.

What are my legal options here? Is it worth pursuing?

Illustrative response

This comes up a lot.

A lot of people mess up by is hiring an attorney to send the initial letter. I'd recommend being patient with the process instead.
