Hillman has had the exact same no-dog policy as East River. But starting in 2014, Hillman issued revised rules that, while not officially allowing dogs to live in the coop, seek to regulate the dogs that do live there. Namely:

• Dogs in Hillman are required to be registered annually for $100 with a DNA sample that will allow feces to be identified if left on Hillman property.
• Each apartment may have no more than one dog.
• No dog may weigh more than 35 pounds.
• Disruptive dogs may be denied registration.

Why create this seeming contradiction? A blanket no-pet policy is superseded by New York City law that prohibits landlords from evicting tenants who have lived openly with a pet for 90 days. That means that if a cooperator is not served with a notice within 90 days of bringing in a pet, management has no recourse at all. This new policy is meant to give the coop some additional control over which pets may be allowed.
