It depends - I ve had smaller packages left outside my door, and larger packages left at the rental office. If they leave it at the office, they ll put a slip on your door.
If your apartment complex is large enough, they ll probably leave it at the office. It also depends if the package requires a signature - if it does, its not likely to be left anywhere. You might have to pick it up from a local UPS warehouse.
Usually the it will be left at the front door. Only sometimes, if they don t think it will be safe, do they give it to the office to hold for pickup.
they could give u a small notice saying its at a near post office?
