In the case of cooperative buildings, a joint appeal must be filed by the Board because there is only one assessed valuation for the entire cooperative property.

The following information must accompany each cooperative valuation appeal:

1. A copy of the cooperative’s Articles of Incorporation and all other rules and regulations which concern the length of proprietary leases and the sales or transfer of shares;
2. All ground lease information, if applicable;
3. A complete legal description of the cooperative’s property including a list of permanent index numbers of all property owned by the cooperative including recreational, parking or other facilities, whether adjacent or not;
4. A description of the size of each unit and the unit blend of the building(s);
5. Interior and exterior photographs of the building(s);
6. Any information relating to the number of shares or percentages of ownership assigned to each unit;
7. Any information relating to the number of outstanding shares;
8. Any information relating to any purchase contracts, or sales, transfers or assignments of beneficial interest of any shares or percentages of ownership in the cooperative within the last five years;
9. Actual construction or renovation cost information if the building(s) has been constructed or renovated within the last three years;
10. Three years of financial statements which include the year-end mortgage balance, and income and operating expense information.
