Your loading footage has to be shot from the alley
Most commercial buildings in this city have no dock and no room to work off the street, so the rear alley is the entire answer to how goods get in and out.
The block grid puts a service alley behind nearly everything. A greystone with a storefront under it, a corner building in Bridgeport, a small warehouse off Ravenswood: the doors that matter face the alley, and a flyer line about rear alley access tells an occupier none of what they need to know.
What they want is whether their truck makes the turn. Alleys here are narrow, and the run to a door is crossed by garage aprons, dumpster enclosures, parking pads and whatever the block leaves out. A driver either swings it or backs the length of it every delivery for the whole term.
So film the approach rather than the door. Come in off the street the way a delivery would, take the turn, stop at the building, then show the step or the ramp and where a pallet jack goes from there. One continuous clip settles the question, and it is footage a portal listing will never contain.
Keep the frame on your own building. An alley is shared ground, and a slow pan down the block puts the back of somebody else's business into your marketing for no gain at all. The approach and the door are what the occupier came for.
