But I see many questionable aspects about this extra charge and requirement now and in the future such as those "representing the unbanked" or "enforcing" the ADA looking for an opportunity for a case to file (Especially for large complexes), etc..

U should open a marriage counseling services ad a side business.  

big loophone in ADA law of u ask me. ...I saw the turkey as a service animal on the news,  and the news segment

I would also have some of that criteria placed in your ad as well as stapled to the application when the PM is handing it out to the applicants at your property showings. 

Assistance animals are not protected under the ADA.

This is probably an ADA topic.

Just don't violate ADA on this one. ..don't ask what her disability is, etc.  

Yes.Am I allowed to demand proof, without violating ADA?

We also print our mission statement in our ad as well: "We strive to provide safe, clean, affordable, comfortable and quiet housing for responsible renters in the neighborhoods of west Vancouver."

An ADA violation could turn out to be much more expensive than the damage a pet could contribute.
