房东有权力要求申请人提供service dog 证书吗？刚

有个申请者说by law 不需要提供.....

额查了下网上写着In general: 1. A landlord cannot require a pet deposit for a service animal. ... A landlord is permitted to require some sort of proof of disability as a condition of accommodation, and some sort of proof the animalin question is a trained service animal, though generally he cannot require certification per se.

这里的可以要proof 但不能是证书？

谢谢大家
