The current unit of analysis is buildings, yet there are many reasons for migrating to a unit-level representation of the housing stock. Units can have separate attributes such as floor, view, deeded affordability, as well as tenure, which could be fixed for a building, or change with economic conditions.
The main work for this suggestion would be in sorting out all the places the model currently touches the buildings table and replacing with a new units table, keyed on buildings.
