This area is a minefield for those who are not well schooled in what they can say and can’t say and how they need to deal with such requests. As many people here know, our company has helped many clients and customers deal with the whole area of Fair Housing, the Americans with Disability Act, and SACRA. We have put on a number of full-day classroom training events for a number of state associations and are working closely with Rick Robinson of MHI to help community owners deal with this explosive issue.
Our clients and customers use forms rather than conversation to deal with this that we had a well-known law firm create. Using this process cuts down on dangerous conversations and documents the whole process. The help you need is not coming from Google, Google & Google. With that warning here is an answer to your question.
Federal law is very specific regarding Service Animals (only dogs and miniature horses) in a residential setting. The certificates you referenced are worthless in complying with federal law and have no authority over you. Service Animals to be validated need a written letter of opinion from a qualified medical professional that has actually examined the individual claiming a disability and a written letter from a qualified trainer certifying the animal has been trained to complete the needed service by that trainer and further the animal has been trained to not be a danger to others and further yet that the animal is housebroken.
Emotional Support animals are not limited to dogs or miniature horses, but the need can only be validated with a written letter of opinion from a qualified mental health professional who has actually examined the individual and asserts that a particular animal is in fact necessary for the emotional stability of the individual requesting an accommodation.
There are other things a community owner may require of people requesting an accommodation before approving the accommodation.
It is a criminal offense in 18 states to represent either a need or that an animal meets the criteria, if in fact it is a deception to get around normal rules of residency. A bill is being introduced in the Illinois House soon that will make the issuance of fraudulent certificates or misrepresentation of need or animal qualification a Class Four Felony. It is expected to pass both houses and that the Governor will sign it and to go into effect in July of 2018. The Bill is being pushed by the Illinois Manufactured Housing Association and has the backing of both apartment associations.
All of that said, be very careful of what you do, or don’t do, without the proper knowledge and system in place first. The prosecutions and the fines have been horrific for even those trying to be careful.
BTW: The link you supplied went to a fraudulent provider of documents so I would not waste brain space on what they put on the internet.
