§ 223-b. Discrimination against a person who is deaf or hard of hearing who has a hearing dog. No person who is deaf or hard of hearing shall be denied occupancy in a dwelling in any project or be subjected to eviction from any such dwelling on the sole ground that such person owns a hearing dog as defined in section forty-seven-b of the civil rights law, provided, however, that if after occupancy a health hazard results on account of such dog, the public health officer having jurisdiction may take such corrective measures as may be appropriate.
