Requirements for Multi-Family Mailboxes in WI

Mailbox regulations in Wisconsin 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 ensure compliance with any additional regulations or standards specific to your area.

  • Placement and Height
    Mailboxes must be placed 6 to 8 inches away from the curb. The incoming mail slot or door must be between 41 and 45 inches from the ground.
  • Address Visibility
    Each mailbox must visibly display the address, with numbers at least 1 inch tall, located on the front or flag side of the box.
  • Cluster Box Units (CBUs)
    For new construction or major renovations, USPS requires STD-4C Horizontal Mailboxes or CBUs to be installed. 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.
  • Parcel Locker Ratio
    There must be 1 parcel locker for every 5 mailbox compartments in multi-family units.
  • Mailbox Supports
    In Wisconsin, mailbox supports must comply with standards established by the Wisconsin Department of Transportation. Plastic posts are prohibited and supports should not pose a hazard to public use of the right-of-way.
  • Snow Removal
    Homeowners or homeowners' associations are responsible for removing snow and ice within the time required by local ordinances.
  • Building Codes
    Multifamily dwellings constructed after April 1, 1995, must comply with Wisconsin's Uniform Multifamily Dwelling Code.
  • Americans with Disabilities Act (ADA) Compliance
    Mailbox access heights should range from 15 to 48 inches above the floor for forward or side reach accessibility.
  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.
