Are you the property manager of an older apartment complex? If so, you may have heard rumblings in recent years of the USPS making changes to mailbox requirements. And, we’re here to reinforce this message that a 4B to 4C cluster mailbox transition has become a significant factor in both new constructions and substantial renovations. 

For those not in the know or reading this article just for fun, cluster box units (CBUs) are freestanding mailboxes with multiple compartments and parcel lockers that lock individually. These USPS-approved cluster mailboxes are commonly used in apartment complexes, commercial properties, and other multi-family housing projects. 

The USPS delivers mail and parcels directly to the compartments and lockers. And, residents can then easily retrieve their posts and packages.

Why the Switch from 4B to 4C?

The shift from 4B to 4C cluster mailboxes isn’t just a matter of preference; it’s a requirement for all new constructions and significant renovations. But what exactly is considered a “significant renovation”? A significant renovation would be anything that requires tearing down walls or building new ones. So, if you’re making substantial changes to the walls where your mailboxes are installed, gues what? You’ll need to comply with the new 4C standards.

The 4C units are designed to offer more security and efficiency than their 4B predecessors. And this is super important as mail theft at apartment complexes continues to be a big problem. However, they have different dimensions, which means the transition isn’t as simple as swapping out the old for the new. This means that structural adjustments are often required during installation, so planning for increased project costs and potential delays is a must.
