Mold / Health Hazard in Rental | lease says no pets but ESA rights

Quick background on my situation — any input appreciated.

lease says no pets but ESA rights. I've been dealing with this for about 8 weeks now and the situation isn't improving.

I have been renting for 3 years. My monthly rent is $4,097. I have a written lease.

Do I have a strong case? What should my next steps be?

Tbh have you tried reaching out to your state's attorney general? They sometimes have free resources or mediation services.
