In Rutherford Tenants Corp. v. Kaufman, 212 AD2d 416 [1st Dept 1995], the board of a cooperative corporation had approved the tenant's alteration plan, but the tenant exceeded the scope of the plans by constructing a deck in addition to the approved alterations. The board brought an action for an injunction and Supreme Court ordered removal of the deck, restoration of the patio to its former condition, and directed a hearing to assess damages.
