Mailboxes
The Postal Service delivers the mail. It usually does not fix the box.
Cluster mailboxes are typically the association's responsibility, not the Postal Service's. USPS controls only its arrow lock and master door lock; the association generally maintains the structure, landscaping, individual compartment locks, and damage from weather, vandalism, or wear. USPS repairs only damage it directly causes. Confirm the exact split in your CBU placement agreement.
Who fixes what
A cluster box unit, or CBU, is the multi-compartment mailbox structure many communities use instead of individual boxes at each home. Delivering mail into it is not the same as maintaining it. According to Mailboxes.com's overview of cluster mailbox responsibility, USPS does not maintain privately owned CBUs. USPS controls exactly two things: the arrow lock a carrier uses to open the whole unit, and the master door lock. Everything else, the structure itself, the ground it sits on, and each resident's individual compartment lock, is generally the association's job.
What "maintenance" actually covers
This is more than paint. It includes repairing a dented or cracked housing, replacing a worn or jammed individual compartment lock, keeping the surrounding landscaping trimmed and the approach clear, and fixing damage from ordinary weather or vandalism. USPS is responsible only for damage it directly causes, for example a postal vehicle striking the unit. A stuck compartment door, a faded unit number, a cracked base from ordinary wear: that is the association's bill, not the carrier's.
Where the real answer lives
The pattern above holds in most communities, but the exact division of responsibility can differ by the community's specific placement agreement with USPS. That agreement, signed when the CBU was installed, is the document that actually controls, not a general rule of thumb. If the board doesn't know where that agreement is, finding it is the first step, before budgeting for a repair or disputing responsibility with the local post office.
Check yourself
Answer before you read the explanation, recalling it is what makes it stick.
A resident's individual mailbox compartment lock jams from ordinary use. Whose job is it to fix it?
A postal delivery vehicle backs into the CBU and cracks the housing. Who typically covers that repair?
The board wants the exact, binding answer for who pays for CBU repairs in their community. Where should they check first?
