A parcel locker for an apartment building is a set of electronically locked cells in the lobby where a courier leaves a delivery and the resident collects it later with a code. The cabinet is the easy part. Before you buy one, work out who will load it, how residents will get their codes, and how many cells you need on your busiest day. This page answers those three questions with real numbers. It also covers chilled cells for groceries, accessibility and who pays.
Quick answer
- Who loads it decides the design. An integrated delivery platform reserves a cell through an API before its driver arrives. Carriers that don’t integrate need building staff to load parcels, or a courier drop-off screen built for the site.
- Size by parcels waiting, not by apartments. Occupied cells ≈ parcels per day × average days before collection, plus peak headroom. Under the illustrative assumptions below, a 200-unit building needs about 86 cells if residents collect within a day, and about 171 if they take two.
- Mail is separate. In the US, apartment mail receptacles must be USPS-approved. A smart locker supplements the mailboxes. It does not replace them.
- Chilled cells are a custom build. KioskForce supplies them to order, quoted per project. The standard delivery locker is not refrigerated.
- Put accessible cells at reachable heights, between 15 and 48 inches (380–1220 mm) above the floor where the 2010 ADA Standards apply.
Why apartment buildings are buying parcel lockers
Parcel volume has outgrown the lobby. US retail e-commerce reached $340.2 billion in the second quarter of 2026, 17.1% of total retail sales, seasonally adjusted (US Census Bureau, released 18 August 2026). That volume arrives at the front door of every multifamily building, and the usual fallbacks all fail at scale. A package room with no access control loses parcels. A concierge desk becomes an unpaid parcel room. Parcels left in a corridor go missing.
A smart parcel locker replaces those with a record. Each cell knows when it was loaded, by whom, and when the resident took the parcel out. Each cell also has a door sensor, so “the lock was released” and “the door actually opened” are logged as separate events. That record is what settles a “my parcel never arrived” dispute.
Who opens the locker: three loading models
Most first-time buyers miss this question. A locker is only useful to a carrier who has a way to open a cell.
| Loading model | How the courier gets in | Who it suits | What it needs |
|---|---|---|---|
| API-integrated platform | The platform reserves a cell when the order is placed and gives the driver a drop-off code, a QR code or an unlock button in the driver app | Food, grocery, pharmacy and courier platforms that deliver to the building often | The platform integrates with the locker API |
| Staff-loaded | Building staff receive parcels from any carrier and load them into cells. The resident gets a code | Buildings with a concierge or a manager on site in business hours | Staff time, and a workflow for issuing resident codes |
| Courier self-service | A driver chooses the resident on the locker screen and is given a cell | Buildings that want carrier-agnostic drop-off with no staff | Resident directory, notifications, and an agreement with each carrier |
KioskForce’s delivery locker is built for the first model and documents it publicly. The platform calls ReserveCell with the package dimensions. It gets back a cell label, a drop-off code, a pickup code and QR codes for both. A webhook fires when the parcel is in the cell. The API documentation is published at delivery.kioskforce.com. The staff-loaded and courier self-service workflows run on the same cabinet and cloud platform, but they are scoped for each building rather than shipped as a standard screen.
What about US Mail?
The USPS Domestic Mail Manual requires apartment house mail receptacles to be approved by the USPS. It also makes the building, not the Postal Service, responsible for buying, installing and maintaining receptacles, boxes and parcel lockers. The exception is equipment that USPS has authorised itself to own and maintain (DMM 508.2.1.7). A smart parcel locker therefore sits next to your approved mailboxes and does not replace them. Whether a postal carrier will load a third-party locker is a local arrangement. Ask the delivering post office before you count USPS parcels in your sizing.
How residents are notified and collect
On the integrated model, notification belongs to the delivery platform, which already has the customer’s phone number:
- The courier closes the door. The locker reports both the door-open and the door-closed events.
- A drop-off webhook goes to the platform, which sends the resident a pickup code by SMS, push notification or in-app message.
- The resident opens the cell with the code on the touchscreen, a QR scan, or an unlock button in the app. A deployment can offer all three at once, so a flat phone battery or no signal in the lift lobby does not strand the parcel.
- A grace period lets the resident reopen the door if they shut it too early.
- The cell runs an ultraviolet sanitising cycle while it sits idle, 10 minutes by default, then goes back into the available pool.
Two details matter in a residential lobby. The locker keeps a live connection to the cloud, but basement signal is often poor. Every instruction is cached for 30 seconds, acknowledged by the machine and replayed in order if the connection drops, so a door-open command is not silently lost. A parcel the resident is never going to collect can be flagged with AbandonPickUp for the building team to clear, so the cell is not held forever.
How many cells does an apartment building need?
Size the locker by the number of parcels sitting in it at the busiest time, not by the number of apartments. Occupied cells equal the arrival rate multiplied by the average waiting time (Little’s law), plus headroom for peaks:
Cells ≈ (units × parcels per unit per week ÷ 7) × average days to collection × peak factor
The table below uses illustrative assumptions: 2 parcels per unit per week and a peak factor of 1.5. Replace them with your building’s own counts from a fortnight of front-desk logs.
| Units | Parcels per day | Cells if collected within ~1 day | Cells if collected within ~2 days |
|---|---|---|---|
| 50 | 14 | 21 | 43 |
| 100 | 29 | 43 | 86 |
| 200 | 57 | 86 | 171 |
| 400 | 114 | 171 | 343 |
Three things follow from the arithmetic:
- Collection time is the biggest lever. Halving the average wait halves the cells. A firm rule, such as “uncollected parcels move to the parcel room after 48 hours”, sets a hard ceiling on the cabinet.
- The cell mix matters more than the total. The largest parcel you agree to accept sets how many large cells you need, and large cells are the expensive part. Most residential traffic is small and medium, so build mostly small cells, keep a few large ones, and send oversize items to an overflow room.
- Turnover is not instant. After each collection the cell is out of the pool for its grace period and its sanitising cycle. That is minutes, not hours, so it barely affects a building’s cell count, but it does matter on a lunch-hour food locker.
Custom KioskForce cabinets run from 100 to 2000 mm wide and high and up to 1000 mm deep, with up to 100 compartments per cabinet. Cabinets gang together: the delivery cabinet carries ten cells, and a typical delivery installation runs three actuator boards for around thirty cells. A 400-unit building with slow collection is several cabinets, or a tighter collection rule.
Chilled cells for grocery deliveries
Grocery and meal-kit deliveries change the specification. A cold bag left in an ambient cell for six hours is a food-safety problem, and it ends in a complaint against the building.
- What we supply: chilled (refrigerated) cells can be built to order as a custom build, quoted per project. The standard KioskForce delivery locker has no refrigeration. Its cells have a UV sanitising lamp and active ventilation, with an optional per-cell heating pad for hot food.
- What temperature to specify: the FDA Food Code model sets cold holding for foods that need temperature control at 5 °C (41 °F) or below (§3-501.16, 2026 edition). Food safety for a grocery order is the grocer’s responsibility, but if the building advertises “cold lockers”, ask for that target in writing.
- Frozen is different. Holding frozen food is a separate specification from chilled. Say so at enquiry if you need it.
- Keep chilled cells few and large. Refrigerated cells cost more to build and to run. Most buildings need a small bank sized for a grocery tote, not a chilled locker wall.
For how chilled cells work (compressor or thermoelectric cooling, the heat lost when a door opens, and temperature logging), see refrigerated lockers.
Accessibility and placement in the lobby
This is a summary for planning, not legal advice. Rules change; confirm with the regulator where the machine will stand. (As of October 2026.)
| Requirement | Rule | What it means for the locker |
|---|---|---|
| Fair Housing Act | New multifamily buildings of 4+ units first occupied after 13 March 1991 must have accessible common and public use areas | The lobby locker is part of a common-use area |
| Lockers (2010 ADA Standards 225.2.1) | Where lockers are provided, at least 5%, and no fewer than one of each type, must comply with 811 | Keep some cells of every size within reach |
| Reach range (308.2.1, 308.3.1) | Unobstructed forward or side reach: 15 in (380 mm) minimum to 48 in (1220 mm) maximum above the floor | On an 1800 mm cabinet, the top row is out of reach. Plan for that |
| Operable parts (309.4) | One hand, no tight grasping, pinching or twisting, 5 lbf (22.2 N) maximum | Touchscreen, scanner and door pulls |
| Clear floor space (305.3) | 30 × 48 in (760 × 1220 mm) minimum | Leave room in front of the screen and the accessible cells |
| Protruding objects (307.2) | Leading edges 27–80 in above the floor may protrude 4 in (100 mm) maximum into a circulation path | Don’t mount a wall unit with a deep canopy over a corridor |
Which rules apply depends on the building. A leasing office open to the public is treated differently from a residents-only lobby. Take advice from your accessibility consultant.
Practical placement: the cabinet needs a mains outlet, floor space with room for a fully opened door, and mobile or Wi-Fi coverage it can hold. Castors are standard on the delivery cabinet, so it can be moved without new conduit. For lockers outside the lobby or under an awning, see outdoor smart lockers.
Who pays for the locker?
Three funding models work, and the software has to suit whichever one you choose:
| Model | Who owns the locker | How it pays back |
|---|---|---|
| Building amenity | The owner or manager | Fewer lost-parcel complaints, less front-desk time, and in some buildings a resident fee |
| Platform-funded | A delivery or grocery platform | Shorter driver stops and fewer failed deliveries at that address |
| Shared operator network | A locker operator | Sells cell access to several delivery platforms. KioskForce’s delivery software is multi-tenant: each platform has its own API key and sees only its own reservations |
On any model, the touchscreen can play image and video advertising while idle. A lobby with heavy daily foot traffic gives the screen a second revenue line next to the delivery fee.
What to specify if you are buying one
Send these with your enquiry and we can size the building:
- Unit count and two weeks of parcel counts, with the peak day marked.
- Your collection rule: how long a parcel can stay in a cell before it is cleared.
- The largest parcel you will accept in a cell, and where oversize parcels go instead.
- Who loads the locker: which platforms will integrate, and whether staff or carriers load it otherwise.
- Whether you need chilled cells, and how many grocery drops a day you expect.
- The site: indoor or outdoor, power, network, and the floor plan with reach and clearance constraints.
Then compare our published reference points. The configurator gives an instant estimate for a custom cabinet. The K180-6C locker kiosk with six cells starts from USD 1,800, and a delivery locker pilot has an indicative setup cost of USD 20,000 (case study). See vending machine cost for freight, duties and running costs. Lead times are 4–6 weeks for a modified standard build and 8–12 weeks for a custom design. We sell direct and, in some regions, through local distributors. On-site installation is optional, and in some regions a local distributor provides it. Support is by email, and a distributor that supplied the locker handles its warranty and service.
Where this is the wrong answer
- Small buildings. In a building of a few dozen units with a manager on site, a locked parcel room with a sign-in log may cost far less and do the job.
- Buildings where carriers won’t use it. If your main carriers won’t integrate and you have no staff to load cells, a locker can sit half empty while parcels pile up beside it. Settle carrier access first.
- Mostly large items. Furniture, flat-pack and bulk orders don’t fit most cells. If a large share of your parcels is oversize, a managed parcel room comes first.
- Frozen grocery as the main use. Treat that as a separate cold-chain project, not as a few extra cells on a parcel locker.
Frequently asked questions
How many parcel lockers does an apartment building need?
Size by occupied cells at the busiest time, not by unit count. Estimate the parcels arriving per day, multiply by the average number of days a parcel waits before the resident collects it, and add headroom for peaks such as Mondays and the holiday season. A 200-unit building receiving two parcels per unit per week gets about 57 parcels a day. If residents collect within a day on average, that is roughly 57 occupied cells, or about 86 with 50 percent peak headroom. Shortening the collection window is the cheapest way to need fewer cells.
Can USPS, UPS, FedEx and Amazon drivers use a smart parcel locker?
Only if each one has a way to open a cell. A delivery platform that integrates with the locker API reserves a cell and gives its driver a drop-off code or an unlock button in the driver app. A carrier that does not integrate needs another route, usually building staff loading parcels into cells, or a courier drop-off screen scoped for the site. US Mail is a separate matter: apartment mail receptacles must be USPS-approved, so a smart locker supplements the mailboxes rather than replacing them. Confirm carrier access with each carrier and the local post office before sizing.
How do residents know a parcel is waiting?
On an API-integrated KioskForce delivery locker, the locker sends a webhook to the delivery platform the moment the door closes on a drop-off, and the platform passes the pickup code to the customer by SMS, push notification or in-app message. The resident then opens the cell with the code, a QR scan or an unlock button in the app. A grace period lets them reopen the door if they shut it too early, and a pickup the customer will not complete can be flagged for the building team to clear.
Can apartment parcel lockers keep groceries cold?
Chilled cells can be supplied to order as a custom build, quoted per project. KioskForce’s standard delivery locker has no refrigeration: its cells have UV sanitising lamps and active ventilation, with an optional heating pad. If a grocer will leave perishable food in the locker, specify the cold-holding target in writing. The FDA Food Code model sets 5 degrees C (41 degrees F) or below for cold holding of foods that need temperature control. Frozen holding is a different specification again.
Do apartment parcel lockers have to be accessible?
Plan for it. In the US, the Fair Housing Act requires accessible common and public use areas in multifamily buildings of four or more units first occupied after 13 March 1991. Where the 2010 ADA Standards apply, at least 5 percent of lockers, and no fewer than one of each type, must be within reach ranges of 15 to 48 inches above the floor, with operable parts usable with one hand. Take advice from your accessibility consultant on which rules cover your building.
Who pays for an apartment parcel locker?
There are three common models. The building owner buys the locker as an amenity and recovers it in rent or a resident fee. A delivery or grocery platform funds lockers to make its own deliveries cheaper. Or a locker operator owns the hardware and sells access to several delivery platforms at once. KioskForce’s delivery locker software supports the last model directly, because each platform has its own API key and sees only its own reservations. The locker screen can also play advertising as a second revenue line.
How much does an apartment parcel locker cost?
It is quoted per building, because cell count, cell sizes, chilled cells and integration scope drive the price. KioskForce’s published reference points are an instant estimate in the online configurator for a custom cabinet, the K180-6C locker kiosk with six cells from USD 1,800, and an indicative USD 20,000 setup for a delivery locker pilot deployment. Add freight, duties and local installation, and a mobile data plan of roughly USD 5 to 10 per month per machine if it runs on 4G.
