Commercial & HOA Mailboxes

We plan and install centralized mail systems for HOAs, condominiums, apartment communities, and commercial properties across Broward, Miami-Dade, and Palm Beach. Our commercial units are manufactured by Florence Corporation, a USPS-approved manufacturer, and every installation meets current USPS-STD-4C requirements.

Two systems cover almost every property:

Pedestal CBU (Cluster Box Unit) Pedestal CBU installation

Pedestal CBU (Cluster Box Unit)

Free-standing · outdoor

  • Mounted on a concrete-set pedestal — no wall or mailroom required
  • Best for single-family HOA and townhome communities
  • 8–16 tenant compartments plus parcel lockers per unit; units combine for larger communities
  • Weather-rated aluminum with a built-in outgoing mail slot
  • Placement approved by your local postmaster.
4C Horizontal — Surface-Mount Surface-mount 4C installation

4C Horizontal — Surface-Mount

Wall-mounted · covered areas

  • Installs in a mailroom, lobby, breezeway, or covered corridor
  • Best for mid- and high-rise condos, apartments, and commercial lobbies
  • One panel holds tenant doors, parcel lockers, and outgoing mail
  • Surface-mount uses a trim collar where wall depth is limited; recessed sits flush
  • Front-loading for carrier access; fully USPS-STD-4C compliant

Planning a mailbox replacement: a guide for property managers

Replacing a centralized mail system involves USPS, your board, and every resident. This is the sequence we recommend.

  1. 1

    Evaluate the current system

    Document the condition of existing units. Note damage, rust, failing locks, and any compartments the carrier has tagged as unusable.

  2. 2

    Consult your local postmaster

    Confirm mailbox type, location, and mounting requirements before ordering. USPS must approve the placement.

  3. 3

    Select the right system

    Choose pedestal CBUs or a 4C wall panel based on site layout, unit count, and parcel volume.

  4. 4

    Coordinate finishes and numbering

    Match color, door-numbering style, and pedestal or post design to community signage and entry monuments.

  5. 5

    Contact Modern Mailbox Co.

    Send us a photo of the installation site and description of the work to be done. We will schedule a visit for photos and measurements.

  6. 6

    Schedule installation

    Plan the changeover to minimize interruption to mail service. USPS can briefly hold mail during the swap.

  7. 7

    Distribute keys and communicate updates

    Give residents the installation date and clear key-pickup instructions in advance.

  8. 8

    Maintain consistency

    Set a simple upkeep plan: periodic cleaning, touch-up paint, and prompt replacement of damaged locks or parts.

Faded, leaning post replaced with a community-spec black aluminum mailbox — Cooper City, FL

Most HOA and deed-restricted communities require a specific mailbox and post — a set style, color, house-number format, and finish. Sun, rain, and salt air take their toll: faded paint, rust at the base, loose doors, and bent flags. When a mailbox no longer matches the community standard, the association sends a notice.

We replace and restore residential mailboxes to the exact specification your community requires — matching the approved post, box, numbers, and color — and set everything in concrete so it stays straight and solid for years.

Replacement

A new mailbox and post matching your community's approved style, installed and set in concrete.

Restoration

Sanding, priming, and repainting the existing post and box, with new numbers and hardware where needed.

Maintenance

Scheduled cleaning, touch-ups, and part replacement so mailboxes across the community stay uniform.
