How to Set Up a Records Storage Unit So You Can Find Any File in Five Minutes

November 10th, 2026


Somebody calls about a 2019 file. A records unit passes or fails right there. Either someone drives over, walks to the right shelf and is back at their desk inside the hour, or they spend an afternoon lifting boxes off of boxes.
Most of that comes down to how the unit was set up on the first day. This is the setup we would use for a law, medical, accounting, insurance or title office in downtown Waco. None of it costs much. Most of it is a marker and a spreadsheet.
How long each box has to stay is a separate question. We covered it in How Long Does a Waco Office Have to Keep Its Files? Your own retention schedule, from your board, your CPA or your attorney, is the one to follow.

Start by counting boxes, not guessing a size

Count what you have now. Then add a rough guess at what one more year of closed files adds. That second number matters more than the first, because a records room only grows until the first purge.
The math is simple. A standard banker's box measures about 10 inches tall, 12 inches wide and 15 inches deep. Stacked no more than about five high, each stack takes a floor spot about a foot wide and fifteen inches deep. Then take away room for a walkway, because a unit packed wall to wall is storage you cannot use.
Here is roughly how that works out in the small sizes, with boxes five high and the 12-inch end facing out where you can read it:
  • 5x7.5: two rows down the long walls with a walkway between them. About 7 stacks a side, so roughly 70 boxes.
  • 5x10: the same two-row layout, about 10 stacks a side, so roughly 100 boxes.
  • 10x5: a row along the back wall and a short row down each side, open in the middle. Roughly 80 boxes.
  • 10x7.5: the same U shape with longer sides. Roughly 110 boxes.
Treat those as starting points. Where the door sits, how full you stack and whether you add shelving all change the count. For most single offices, one of these four sizes is plenty. If you are not sure, come measure before you pick.

Shelving or floor stacks

Floor stacks hold the most boxes for the least money. The catch is the box you need is always third from the bottom.
Shelving costs more and holds a little less, but every box comes off on its own. If your staff pulls files more than a few times a month, shelving pays for itself in time. If the boxes are there to sit until they are shredded, floor stacks are fine.
A middle path works well: shelving for the recent years you actually go into, floor stacks for the old years that are just waiting out the clock.
If you buy shelving, measure the unit first, height included, and bring the tape measure with you. Steel shelving about 18 inches deep fits a banker's box with a little room to spare. Keep the heaviest boxes low.

Keep a walkway, every time

Leave a clear lane from the door to the back wall, wide enough to stand in and turn around with a box in your hands. Do not fill it "just for now." Once the walkway is gone, every trip turns into moving furniture, and people stop going.

Label every box the same way

Pick one label format and use it on every box. Write it on the end that faces the walkway, big enough to read from the door:
  • Office name, if more than one practice or partner shares the unit
  • Box number, running in order and never reused
  • Client or file range, like "Smith to Thompson" or "Claims 4410 to 4520"
  • Year the files closed
  • Destroy-by date, month and year
Mixing years in one box makes the destroy-by date a mess. When a box is full, close it and start the next number.

Keep the index at the office

The labels tell you what a box is once you are standing in front of it. The index tells you which box to go to before you leave the office.
A simple spreadsheet is enough. One row per box, with columns that match the label, plus a column for where it sits, like "left wall, stack 4, third from top" or "shelf B, second shelf." Save it where everyone in the office can open it.
When someone asks for a file, search the spreadsheet, write down the box number and location, and go. That is the whole five minutes.

Put the years you use most by the door

Arrange the unit by how often you go into it, not by when you moved the boxes in. The last two or three years usually get pulled the most, so they go closest to the door and at a comfortable height. Older years go toward the back.
Some offices do the reverse and put the next boxes due for shredding up front. That makes the yearly cleanout quicker. Pick whichever trip you make more often. For most offices that is the trip for a current file.

Pull the expired boxes once a year

Put one date on the calendar every year. Sort the spreadsheet by destroy-by date, pull everything that has passed, and check that none of it is on hold for a lawsuit, an audit or a records request. Then hand the rest to your shredding company and mark those rows as destroyed. Keep the rows; do not delete them. The record of what was destroyed is worth keeping.
That one afternoon a year is what stops a 5x10 from turning into a 10x10.

What the building does for a records room

Every unit at Downtown Storage is climate controlled. Paper and file folders do better in a steady, dry room than in a metal box that bakes all summer.
The units are on the ground floor of a retrofitted historic building at 1225 Franklin Ave. One flat floor, no steps. Free carts, flatbeds, hand dollies and a pallet jack are staged by the door, and you load under a covered loading canopy, so a car full of boxes can come in on one cart in one trip, rain or not.
The gate is open 6 AM to 9 PM every day. 24-hour access for business tenants is available. Ask about it when you call.
Rent is month to month and collected on the 1st. When you no longer need the unit, give ten days' notice to move out.
The office is by appointment. Call (254) 870-6361 and we will meet you there so you can measure a unit yourself. Sizes are on our document storage page.
