Found this, HUD guidelines for service, and assistance animals
I found this article that links to the new HUD guidelines on Reasonable Accommodations For Assistance Animals, including Service animals, and emotional support animals.
the actual guidance does not change any current laws, but it does help to clarify and provide some best practices for us as landlords and tenants seeking to request reasonable accommodations.
