Home > Guides > Cluster box ownership
The property owner or homeowners association, not the post office. In the US, cluster box units in newer neighborhoods are bought and installed by the developer, and USPS owns nothing except the carrier's master lock. The HOA or landlord handles broken doors, damaged boxes, and individual locks. Canada is the opposite: Canada Post owns and maintains community mailboxes.
| Part of the box | Who owns and fixes it (US) |
|---|---|
| The unit itself (doors, frame, pedestal) | Property owner, HOA, or landlord |
| Your individual compartment lock | Property owner, HOA, or landlord |
| The carrier's master (arrow) lock | USPS, and only USPS, forever |
| Parcel lockers in the unit | Property owner, HOA, or landlord |
It used to, in some cases. Older neighborhood delivery and collection boxes installed by the Postal Service before a policy change around 2012 may still be USPS-maintained. But for new construction since then, the rule flipped: the builder or developer buys an approved cluster box unit, installs it where USPS approves the location, and hands maintenance to whoever owns the property, usually the HOA. The logic is that centralized delivery is cheaper for USPS, but the hardware belongs to the community it serves.
This is why calling your local post office about a broken cluster box door usually gets you a polite redirect. The carrier can report it, but the repair order goes to your property manager, not a postal maintenance crew.
Every cluster box has two kinds of locks, and they belong to different worlds. Your compartment lock is yours, or rather your HOA's. If it jams, breaks, or you lose the key, the property manager arranges a locksmith or a replacement lock. They may charge you for it, especially if you lost the key.
The carrier's master lock, called the arrow lock, is the one piece USPS owns outright. Only USPS master keys open it, and nobody else is allowed to touch it, not the HOA, not a locksmith, not you. If the arrow lock itself fails, that is the one cluster-box repair that genuinely is the post office's problem.
Lost key: your property manager or HOA. They keep records of which compartment is yours and arrange a new lock or key. Vandalism or a pried-open door: also the property manager, though this is worth reporting to the Postal Inspection Service as well, since mail theft is a federal matter. Structural damage, a leaning pedestal, a rusted frame: the HOA's reserve budget, not USPS.
One practical tip: when you move into a place with a cluster box, get your compartment key from the property manager before you need mail there. Carriers cannot hand you a key, and the post office counter usually cannot either, because they do not control the locks.
No, it is the mirror image. Canada Post community mailboxes are owned, installed, and maintained by Canada Post itself. If a community box in Canada is damaged, you report it to Canada Post, and they send their own people. Key replacement also runs through Canada Post's process. So the short version: in the US, the box belongs to the neighborhood and the lock to the carrier; in Canada, the whole thing belongs to the post.
