@Kimberly TI checked my NOLO  Every Landlord's Legal Guide, and this is what it said:...The courts in California have construed the Unruh Act to forbid all discrimination on the basis of one's personal characteristic or trait.Even if you live in a state that does not specifically outlaw arbitrary discrimination, there is a very strong practical reason why you should not engage in arbitrary discrimination-- for example, based on obesity, occupation, or style of dress.  

There was a movie called "Animal House" - crazy frathouse  behavior - that is one explanation.

Have you decided that you want the extra expenses that animals will add to your rentals?

This is the California law regarding service animals:http://www.disabilityrightsca.org/pubs/548301.pdfAn emotional support animal doesn't have to be a dog. 

Other reasonable accommodations to consider would be visual doorbells, visual smoke/CO detectors, and allowing hearing assistance animals.

I name the pets allowed in the lease.You cannot restrict service animals and this gets sticky in the case of "companion" animals for those with a disability.

Specifically the unsanitary smell and amount of animal waste improperly disposed of and on the floors.Please be aware that the condition of your apartment is unacceptable and unsanitary for not only you but your animals as well.

so most of us here, already privvy to the many pet vs service/support animal posts, know by now that true service/support animals are not just pets.  

I'm going to have to disagree with Jonathan on the basis of California tenant law being an ENTIRELY different animal that Georgia.

Either the property is being damaged by animals or kids.Personally, I think the landlord was more than reasonable.
