Storage Lockers in Apartment Buildings: Turning Unused Space Into Rent
On this page
Many apartment buildings have space that earns nothing: a corner of the garage, a basement room, a strip of unused hallway. Residents often want somewhere to keep bikes, seasonal gear and boxes. A sponsor can build a row of storage lockers, rent them to residents by the month and treat the income as part of the building's other income. The idea is simple. The math is where it fails, so it has to be tested before the build.
This guide covers what storage lockers cost, how to test occupancy and how to calculate payback. It is not advice on fire or building codes. The local fire marshal and the building official decide what is allowed in a garage, basement or corridor.

What does a storage program cost?
- Build-out. Wire mesh or solid panels, framing, a door, lighting where the space is dark and a lock for each locker.
- Layout and permits. The design must keep exits and paths clear, and the local building official may need to approve it.
- Program costs. Lease paperwork, the cost of assigning and tracking lockers, insurance on the added space and any cleaning.
- Turnover. Lockers empty out when residents move, and the cost to clean and re-rent them belongs in the plan.
Hypothetical example
These figures are made up for illustration. Get the build-out bid and the local code answer before you commit.
A building plans 20 lockers in an unused garage corner at $1,100 each, a total build-out of $22,000. The owner rents each locker for $25 a month. The program costs $600 a year to run, including lock changes and the share of the insurance for the space.
Two cases show the range.
| Measure | Base: 75% rented | Downside: 40% rented |
|---|---|---|
| Lockers rented | 15 | 8 |
| Yearly rent at $25 a month | $4,500 | $2,400 |
| Less yearly program cost | $600 | $600 |
| Net yearly income | $3,900 | $1,800 |
| Payback on $22,000 | 5.6 years | 12.2 years |
The base case pays back in under six years. The downside case takes more than twelve, and the owner should be willing to hold the space that long. If the lockers fill slowly, the plan should show the slower lease-up, not the full occupancy from day one.
How do you test demand?
Ask the residents first. A short survey, a waitlist or a deposit on a locker shows demand better than a guess. Compare the rent with storage rents nearby. If the nearest storage facility is cheap or a resident can keep items in an apartment closet, the demand is weaker. Count only the rent that a lease supports.
What should you check before you build?
- The fire code for storage in a garage, basement or corridor, with the local fire marshal.
- Exit and egress paths, which must stay clear.
- Sprinkler coverage, where the code requires it.
- Lighting and access for residents, and how the locker is assigned and tracked.
- The insurance policy's rules for stored items and fire risk.
- The lease language on what residents may store, including items the building does not allow.
Where does storage income fit?
Storage is part of other income, and underwriting should count only the rent that recurs and is documented. The other income guide explains how to separate recurring income from one-time fees. Keep the storage line small and tested. A plan that counts storage at full occupancy from the first month overstates the building's income.
How DoorRaise fits in
DoorRaise helps sponsors raise equity for apartment buildings with 5 or more units under Rule 506(b) or 506(c). The deal's value-add budget and income assumptions show the build-out cost, the occupancy test and the payback, so investors see the range and the loss case. DoorRaise does not build or lease storage. Setup is $1,500 (non-refundable), and the administration fee is $5,000 a year from closing.

FAQ
Can I put storage lockers in a garage?
Sometimes. It depends on the fire code, the clear paths and the sprinkler rules for the garage. Ask the local fire marshal and the building official before you design the layout.
How much should a storage locker rent for?
Use the rent that residents will pay in your building, tested with a waitlist or nearby storage rates. Do not use a rate from a different market.
Should storage income go in the operating budget?
Yes, as other income, once it recurs and is documented. Show the build-out separately as a capital cost.
Do residents need to rent a locker?
The lease decides. Some owners include a small locker with the unit and rent extra space for more. Whichever you choose, state it in the lease.
