2. Accommodations. For any owner, lessor, sublessor, managing agent or other person having the right to sell, rent, lease or manage a housing accommodation or any of their agents to refuse to make reasonable accommodations in rules, policies, practices or services when those accommodations are necessary to give a person with physical or mental disability equal opportunity to use and enjoy the housing; or

3. Assistance animals. For any owner, lessor, sublessor, managing agent or other person having the right to sell, rent, lease or manage a housing accommodation or any of their agents to refuse to permit the use of an assistance animal or otherwise discriminate against an individual with a physical or mental disability who uses an assistance animal at the housing accommodation unless it is shown by defense that the assistance animal poses a direct threat to the health or safety of others or the use of the assistance animal would result in substantial physical damage to the property of others or would substantially interfere with the reasonable enjoyment of the housing accommodation by others. The use of an assistance animal may not be conditioned on the payment of a fee or security deposit, although the individual with a physical or mental disability is liable for any damage done to the premises or facilities by such an assistance animal.
