Class 2: All other property that is not in Class 1 and is primarily residential (rentals, cooperatives and condominiums). Class 2 includes: Sub-Class 2a (4 - 6 unit rental building); Sub-Class 2b (7 - 10 unit rental building); Sub-Class 2c (2 - 10 unit cooperative or condominium); and Class 2 (11 units or more).
