Yes, many Brooklyn apartment buildings require you to provide a Certificate of Insurance (COI) from your moving company. Otherwise, management won’t let your movers into the building on moving day. A COI proves to your building’s management that your movers are insured and that the insurance will cover any damage the movers cause to the property while they’re moving your stuff.1 Luckily, a COI isn’t too difficult to get. You just need to request it from your movers ahead of time and send it to your building’s management. Note that you need to request a COI for the building you’re moving into and the building you’re moving out of, so you usually need two COIs per move unless one of your buildings doesn’t require it. You should also know that movers usually charge a fee to supply a COI. The exact price depends on the company, but it usually costs $45–$60 per COI.
