Amazon’s got this locked up.

Amazon already has delivery lockers in various public locations through its Amazon Lockers program, but with its new Amazon Hub service, landlords can have them installed in the lobbies of apartment buildings. Tenants can get parcels of many sizes shipped to lockers and can access them with a personalized passcode.

Amazon is offering one unit with 42 lockers and another with 65. And though it’s not clear how big individual Hub lockers will be, the public Amazon Lockers, released in 2012, can hold items up to 19 x 12 x 24 inches, which is roughly the size of nine shoeboxes.

The price of the service is not yet publicly available, and seems to be determined on a case-by-case basis. Interested building owners are asked to fill out a questionnaire with details about their building and location. While Amazon is strongly targeting tenants with its marketing, perhaps hoping they’ll pressure their landlords, Hub’s website also notes that the lockers will save building owners the trouble (and likely cost) of having to manage and store their tenants’ packages. The lockers can be opened 24/7, and require no doorman or onsite staff.

And the best part: They’re not just for Amazon deliveries. The lockers are open to shipments from any retailer, and even care packages from family and friends.

For Amazon, the service is part of a new push to innovate not just in retail, but in package management and delivery, as the retail giant gears up to take on FedEx, UPS, and DHL. Joining its predecessors Prime Air and Colis Prive, Hub puts a new customer service spin on Amazon’s model, and has the potential to cut its delivery costs as well, as redelivery becomes a thing of the past.

Hub could also be a lifesaver for apartment dwellers, for whom receiving a package carries a security risk. In 2015, 23 million people said they’d had a package stolen before they could pick it up.  And even for those who have never been a victim of theft, the thought is still stressful: 53 % of U.S. homeowners are worried about their packages being stolen.

And of course, it’s convenient. Tenants of apartments without lobby space often have to pick up packages from their post office or building management office, which severely limits the time frame in which they can do so. With Hub, you can pick up your package on your schedule.

That said, there are a few things to watch out for. It’s not yet clear how well Hub will work, but customers of Amazon Lockers have reported technical difficulties while retrieving their packages. And remember that for now, it seems these lockers can only hold relatively small packages, so you’ll still need to pick up your furniture somewhere else.

If you’re interested in getting Hub installed in your building, direct your landlord to Amazon’s questionnaire.
