Roughly 4 units, and that is an estimate, not a count. The roll does not publish a unit count for most buildings, so this figure is the floor area divided by 900 square feet, corrected by class code only for houses and small duplex-to-fourplex classes. It is the same number as the living area above, divided. Treat it as a size band, not a fact
