In New York, the building is often the hardest part of the move. Co-ops, condos, and managed rentals all have rules about when and how you can move, and a crew that shows up without the right paperwork can be turned away at the door.
Start with the certificate of insurance, or COI. Most managed buildings require one from your mover, naming the building and the management company as additional insured. Ask your management office for their exact requirements at least a week ahead, then send them to your mover. We issue COIs for both your old and new buildings.
Next, book the freight elevator and the move window. Many buildings only allow moves on weekdays within set hours, and some charge a refundable deposit. If both buildings have windows, line them up so the truck isn't waiting between the two.
Finally, think about the curb. Tell your mover about loading docks, hydrants, bike lanes, and whether the street has alternate-side parking on moving day. A good crew plans where the truck will stop before it leaves the yard, and that planning is what keeps a flat-fee move on schedule.
