Submit a move-in notification to the property manager or maintenance company within three days of moving into the apartment. Remember to provide the details of all individuals moving into the apartment. This information is needed for setting up payment details (e.g., water charges, etc.). The property management office will send the payment slips after receiving the move-in notification. By submitting the move-in notification, you ensure that your name is placed on the mailbox and nameplate by the maintenance company (in buildings with a maintenance company). Submitting the move-in notification also ensures that if you forget your keys, the maintenance company can let you in.
