Sliding doors - exterior or common area?

[a guest]

Doors/Windows: how do you determine which area a sliding door belongs to? Are there properties
that have sliding doors (automatic doors that slide to the right and left) that lead from an office to a
hallway or an office to a gym?

Ah! Good one. This is worth a chuckle I think, and pretty simple! Look at which section of the door slides – the inside section or outside section. On most sliders it is the inner section, so most of them are Common Area doors, but on a few brands you will find it is the outer section, making it an Exterior door.
