All of the apartments consist of one (1) bedroom and the maximum number of occupants is two (2).  According to Section 404.4.1 of the Virginia Maintenance Code:

404.4.1 Room area. Every living room shall contain at least 120 square feet (11.2 m2) and every bedroom shall contain at least 70 square feet (6.5 m2) and every bedroom occupied by more than one person shall contain at least 50 square feet (4.6 m2) of floor area for each occupant thereof.

Additionally, Section 404.4 of the Virginia Maintenance Code further states:

404.5.1 Sleeping area. The minimum occupancy area required by Table 404.5 shall not be included as a sleeping area in determining the minimum occupancy area for sleeping purposes. All sleeping areas shall comply with Section 404.4.

The bedrooms at King & Queen Apartments are right at 146 square feet (13.6 m2) each.  Therefore, the bedroom floor area requirement to allow an additional, third occupant would mean the bedrooms would have to be at least 170 square feet (15.8 m2).
