I recently learned from the City (Pittsburgh) that my LL has been cited for building & fire code violations. Inspector told me violations are "very serious" & there is no C. of O. Inspector told me he is about to take the LL to Housing Court, as he's done waiting for her to begin work on the violations. I am looking to move (the inspector says my home isn't safe & that tenants will eventually be forced out because of the ongoing violations and lack of C of O). My lease (on what turns out to be an illegal dwelling, so I'm not sure if my lease is legal or binding anyway???) states that I must give 30 days notice when vacating. LL hasn't given me written notice to vacate. From what I've read, this all equals constructive eviction. Do I still have to give 30 days notice before I vacate???
