I was a resident apartment manager, and was always in fear of losing my job, because my housing was tied directly to it, and if you lose your job, you have to vacate immediately, with none of the usual rights for tenants. People think it's a great job, but don't usually realize this.
I will assume you have already moved out. But, I think you should contact the CA Dept of Labor for help. You were, after all, an employee. And you should file for unemployment. There are circumstances where you can get unemployment, even if you quit. I think your situation qualifies.
Here is the DOL claims page:
California Labor and Workforce Development Agency
Unemployment:
Filing a Claim
Even for resident managers, the employer has to cover you for unemployment and workers compensation. So, I think you should file for unemployment, and contact the DOL for help regarding the issues with your employer.
If the employer is actually threatening you, you should also contact law enforcement, IMO.
I'm so sorry this has happened to you.
