The apartment is the easy part. Movers do apartments all day. What slows a job down is everything between the truck and your door, and most of that is decided by a building you don't control and a set of rules nobody handed you when you signed the lease.
A good crew will ask you a dozen questions before the date. If nobody asks, ask yourself, because the answers change the truck, the crew size and the hour they need to arrive. Here's what actually matters, gathered from watching too many moves go sideways on the sidewalk.
The certificate of insurance and who has to be named
Most managing agents want a certificate of insurance on file before a truck is allowed near the loading area, and it has to name the right parties. That usually means the corporation or LLC that owns the building plus the managing agent, spelled exactly as the building spells them. One wrong word sends the whole document back.
Get the building's sample certificate in advance, the one with the required wording already on it, and forward it to your mover as an attachment rather than retyping it. Two weeks of lead time is comfortable. Three days is where this becomes the reason a move gets pushed, and I've seen exactly that happen on a first of the month.
Co-op boards ask for more than rentals do
Co-ops and condos often layer their own rules on top. Expect a move-in window, commonly weekdays between nine and four with nothing on weekends or holidays, and expect a refundable deposit held against damage to the lobby. Some boards want the moving company's information submitted in advance so they can check it themselves.
Ask the managing agent for the move-in packet in writing and read the whole thing, including the part about elevator pads and floor protection in the lobby. If your crew arrives to find the marble uncovered and no masonite down, someone is going to be sent out to buy it and your window is going to shrink.
Elevators, stairs and the numbers that matter
Measure the freight elevator if you have one. The interior depth and the door opening height are two different numbers and the smaller one governs. A standard sofa that's seven feet long needs somewhere to go diagonally, and in a prewar cab that's often the ceiling hatch rather than the floor.
In a walk-up, count flights rather than floors, and mention the turns. A straight run to the fifth floor is tiring. A brownstone stairwell with a tight landing every half flight and a newel post at each turn is a different job, and it's the turns that decide whether your armoire goes up at all.
Doorways, hallways and the prewar kitchen problem
Interior doors in older buildings are frequently narrower than the thirty two inches people assume, and the hinges eat another half inch. Measure the narrowest point on the path from your door to the room the furniture is going into. Then measure the furniture at its thickest, not at its most flattering angle.
Tiny kitchens deserve their own warning. A galley kitchen in a prewar one bedroom can be under six feet wide, which means the fridge comes out before anything else goes in and two people can't work in there at once. Say so in advance so the crew sequences the rooms properly instead of discovering it at noon.
The long carry nobody mentions
Distance from the truck to the lobby is a real variable and it gets billed on many tariffs once it passes a set number of feet. A building set back behind a courtyard, or a service door halfway down the block. Pace it out yourself and report the number honestly.
Put all of this into one email and send it before the date, because a crew like Dynamic Movers NYC can plan around a narrow stairwell when it hears about it in advance. The measurements and the elevator hours belong in the same message. Ask them to confirm what they can work with.
Timing, supers and the humans involved
The super is the most useful person in this whole process and the easiest to overlook. He knows which elevator actually holds a load and whether the side door is unlocked at eight. Introduce yourself a week early. Not on the morning of, when he's dealing with three other things.
Move-out and move-in windows rarely line up neatly, especially on the first of the month when half the city is doing this at once. If the two buildings give you four hour windows that don't overlap, the truck sits somewhere in between for a while. Better to know that on Tuesday than to discover it on Saturday.
Write it down and send it once
Text threads scatter. A single page with the addresses and the two building windows is what a dispatcher can actually use at six in the morning. Put the apartment numbers on it. Put the buzzer code on it if there is one, and note whether the front door needs a key after seven.
None of this is glamorous and all of it is the difference between a move that ends at three and one that ends at nine with everyone furious in a lobby. The building is the job. Learn its rules before the truck does, and the rest of the day tends to behave.
