However, if you can produce CGC papers or the like, it may make the landlord feel more at ease, especially if the property itself doesn't allow pet dogs.
Pets can take the CGC and not required for ESAs or SDs. Basically, if they don't allow pets, the CGC is useless as pets can take that too.
ETA: I didn't mean to sound rude when I said that. I just meant that due to being open to all, yes, it shows that the dog has good mannors but that doesn't mean a pet dog isn't still a pet.
Emotional support animals don't have accessibility rights. Your landlord has a right to consider them pets, I'm pretty sure?
They don't have public access such as stores but DO have access to no pet housing due to the Fair Housing Act, to not discriminate against one with a disabilty. An ESA is included in that.
These are my thoughts, you know your rights but most others don't. My apartment complex seemes to be up on the laws (I have a service dog in training - owner training - which is covered by State Law) so they may be but due to fear of being crossed off the list, which is a vaild fear and not necessarly illegal. If they say no only based on that, thats illegal, but who will know that real true reason when it could be someone could move in faster or willing to pay more or (in my State) had better credit? Though, if they say no due to your ESAs and SD (as long as they are legally are as such) that IS illegal. It is discrimination.
Ok, so what I would do. Have copies of your Drs letters (updated if older then a year), copies of federal ADA and Fair Housing Act and also any State Statues reguarding ESAs and SDs. Also I always have all vet records to show he is up on all shots, and other parasites as well as his heart worm/flea & tick prevention (just me personally) and then don't tell them straight off. Ask for any disabilty accomendation if needed such as wheelchair ramps and handle bars but I wouldn't say a thing. Apply and move in. If they approach you about it after you move in, advise they are ESAs and SDs and provide all the info.
I will say that your doctor's letter should individually state each animal and what they do for you and why you need this cat AND that one AND a SD etc. As I can see that being an issue or something they may state. But if its in your Drs letter as a needed thing (to have them all) then its legally so.
ETA: I should add that I don't believe you must present any documentation in the fair housing act, and between federal law and state law, the one that applies is the one that more greatly protects the disabled person. But its what i do as its now in my file and a new person can't come along later and bother me as its all in my file.
Legally though, I believe the two question only applies. And I certianlly wouldn't offer it at any point.
ETA (I hope it's ok to add this as I believe education about SDs, ESAs, and TDs is very important):
This whole situation with emotional support dogs, service animals, thearpy dogs is beyond confusing!
Emotional support animals (can be any animal) aren't trained to do anything. They provide only emotional support by sitting there and being petted. They are allowed on airplanes and in no pet housing but cannot access other places such as stores and restraunts.
Therapy dogs are for others. To be brought into a hospital or elderly care for others to pet and play with etc. The CGC is required for a therapy dog still I believe.
Service Dogs (or miniture horse) is specially trained to preform a service (or tasks) for the handler such as guiding a blind person, alerting to anxiety and seizures, doing Deep Pressure therapy, giving physical personal space, giving mobilty assiatance, picking up items, carrying items, opening/closing doors just to name a few out of the MANY things a dog can be trained to do. The the differences in ESAs and SDs are SDs being trained to preform services that the handler cannot do for themselves.
