I know they foster out kittens and puppies. I'm not sure about bigger cats and dogs. Have you tried getting them registered as emotional support animals?
Get your vet or dr to do paperwork confirming they are "certified emotional support pets. That is a pretty solid thing Calif. landowners are bound to allow for their tenants.
