Requirements for Multi-Family Mailboxes in MN

Mailbox regulations in Minnesota are primarily governed by the United States Postal Service (USPS) standards, local municipal codes and specific requirements for multifamily dwellings.

It's essential to consult with local authorities or the local postmaster to comply with any additional regulations or standards specific to your area.

  • Placement and Height
    Mailboxes in Minnesota must be installed 6 to 8 inches back from the curb or road edge, with the bottom of the mailbox or mail entry point positioned 41 to 45 inches above the ground or road surface.
  • Address Visibility
    Each mailbox must clearly display the address number, with numerals at least 1 inch high, placed on the front or flag side for visibility.
  • Cluster Box Units (CBUs)
    For new construction or major renovations, USPS requires the use of STD-4C Horizontal Mailboxes or Cluster Box Units (CBUs). The highest tenant lock must be no more than 67 inches above the finished floor and the lowest must be at least 28 inches above the finished floor.
  • Parcel Locker Ratio
    In multi-family housing, there must be at least one parcel locker for every five mailbox compartments in new installations.
  • Mailbox Supports
    Minnesota requires crashworthy installations. Supports should meet NCHRP 350 or MASH criteria. Prohibited supports include concrete-filled cans or rigid decorative structures. MnDOT’s support policy notes noncompliant supports may be removed under Statute 169.072.
  • Mailbox Placement
    Local rules align with USPS placement standards. For example, Goodhue County allows swing-away installations using a 4″×4″ wood post or 2″ steel pipe.
  • Locking & Parcel Delivery
    Locking mailboxes are allowed if USPS-approved. Deposit slots must suit daily mail and unfolded Priority envelopes. CBUs must include parcel lockers per STD‑4C rules.
  • ADA Compliance
    In centralized multi-family setups, at least one compartment must be no higher than 48 inches AFF. Parcel lockers must sit ≥ 15 inches off the floor. Arrow-locks should fall between 36 and 48 inches AFF.
  1. Site-Constructed Single-Family Developments
    Developers must coordinate with the USPS during the design phase, as centralized mail delivery with secure parcel lockers is the standard for new communities. If new homes are within one block of existing ones, they may adopt the same delivery method pending USPS review; otherwise, current centralized delivery standards apply.
  2. Mobile or Trailer Home Developments
    Permanent developments must have permanent lot assignments, public road maintenance and typically use centralized, curbside or sidewalk delivery as determined by USPS. Transient developments receive mail at a single USPS-approved location, with park staff handling internal distribution.
  3. Apartment Communities
    Use USPS-approved 4C centralized mailbox units with at least one parcel locker per five mailboxes, installed near main entrances and accessible to carriers. Outdoor units require USPS approval, must avoid streets or sidewalks and include a canopy with lighting and weather protection.
  4. Student Housing & Off-Campus Dormitories
    USPS delivers mail in bulk to a designated representative for distribution within dormitories, with no individual mailbox delivery provided. Dormitories—defined by shared living spaces—require early coordination with a USPS Growth Manager and may need named designees to accept mail.
