Square feet, not units: the occupancy number that should lead
Unit occupancy is the number most operators quote and the one least connected to revenue. Here is what changes when square feet leads instead.
Ask an operator how a store is doing and you will usually get unit occupancy: 412 of 480 units rented, 86%. It is the number on the property management dashboard, the number in the weekly call, and the number that leads the owner report.
It is also the number least connected to what the store earns.
Why the two diverge
A unit is a count. A square foot is capacity. A store that fills its 5×5s and leaves its 10×20s empty can post a strong unit occupancy while a large share of its rentable area sits dark — and rentable area is what the rent is charged against.
Consider two stores with identical unit occupancy at 86%. In the first, the vacancy is concentrated in small climate-controlled units. In the second, it is four 10×30 drive-ups. Same headline, materially different month, and nothing in the reported figure distinguishes them.
Unit occupancy flatters any portfolio with a lot of small units. That is most portfolios.
What leading with square feet changes
- 01The vacancy that costs the most becomes the vacancy that is most visible.
- 02Unit-mix problems surface as occupancy problems, which is what they are.
- 03Month-over-month movement starts tracking revenue movement, so the two stop contradicting each other in the same report.
- 04A store cannot post a strong month by renting its cheapest space.
Keep the other two visible
This is an argument about which number leads, not about which numbers exist. Unit occupancy still answers a real operational question — how many customers are on site, how much traffic the office handles, how many gate codes are live. Economic occupancy still tells you what share of potential rent you are actually collecting, which is where concessions and delinquency show up.
The failure mode is a report that shows one of the three and lets the reader assume it stands for all of them. Show all three, and put square feet first.
