All the comments and advise in response to your concerns are spot on, but that does not allow ESA and service animals to become nuisances or destroy other neighbors peaceful and quiet enjoyment of their homes. If any of these animals bark incessantly, have accidents that are left in the public spaces, pose a threat to residents and guests, or cause an apartment to smell so bad it the odors migrate into the public spaces or adjacent apartments, Boards have the right to pursue remedies for removal of animals because they are breaking other house rules on issues of quality of life and, in some cases, health department issues. Train your service dogs and ESAs so they are not disturbing your neighbors!
