All units at Maui Vista are identified by a four-digit number. The first digit is the building number (1, 2, or 3). The second digit is the floor number (1, 2, 3, or 4). The last two digits are the unit number for that building and floor.

The image to the right shows the entry to units 17 and 18 on the fourth floor of building 2.

There is a directory sign near the elevator door on each floor of all three buildings. The image below shows the directory for floor 2 in Building 2.
