Can LL break lease because I called SFDBI?

After signing a 1yr lease for an apartment that was promised “ready to move in”, but, in reality wasn’t. Since taking possession, I encountered an ant infestation, “red” water spewing from the tub faucet, no deadbolt, no heat, no fire alarms/detectors and CO2 detectors, broken windows, etc. Some of the issues were taken care of after shaking heaven and earth. Yet, others have been deemed as “normal” by the LL. The LL told me that the place was legal and up to code; it wasn’t. The LL brought an “inspector” who profusely refused to properly identify himself and tried to impersonate a city inspector.l; ‘til this day I do not know who he was, but, he pranced my whole unit. Now, the LL said he was going to bring an “architect” to check out my unit. When I asked for this “architect’s” Information, the LL said it was the same “inspector” and he required his permission to give out his info; I didn’t feel comfortable, so, I called the real inspector from SFDBI. The real inspector has noted that the unit is ilegal and there are some building code violations. After the real inspector left, the LL told me that he would like to break the lease and give “some” money to move out. Is this legal?
