Requirements for Multi-Family Mailboxes in TX
Mailbox regulations in Texas 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.
USPS Mailbox Requirements
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 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.
Parcel Locker Ratio
In multi-family housing, there must be at least one parcel locker for every five mailbox compartments in new installations.
Texas-Specific Mailbox Requirements
Mailbox Supports
Mailbox supports on Texas state highways must meet Texas Department of Transportation (TxDOT) standards. Approved supports include wood (up to 4″x4″) or metal pipes (up to 2″ diameter), buried less than 24 inches deep. Supports must be crashworthy and break away if struck; heavy steel, cast iron or decorative supports are not allowed. Plastic posts are discouraged.
Locking Mailboxes
Locking mailboxes are permitted and growing in popularity for security. All locking mailboxes must be USPS-approved, with slots large enough for normal daily mail and unfolded Priority envelopes. USPS carriers do not accept mailbox keys and will not open locked boxes, so the design must allow mail to be deposited without carrier access to the lock.
Building Codes
Multi-family projects in Texas must comply with local building codes and USPS mailbox standards. There is no single statewide building code for all developments, so check municipal requirements for your area.
Americans with Disabilities Act (ADA) Compliance
Accessible mailbox compartments in multi-family properties must be positioned 15–48 inches above the finished floor for forward or side reach, in accordance with ADA guidelines.
Requirements by Property Type
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.
Mobile or Trailer Home Developments
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.
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.

Fastest Growing Multi-Family Property Investments in Texas
Multi-family housing is reshaping Texas’s major cities, with the state
remaining a national hotspot for apartment and condo development.
Dallas, Houston and Austin are leading this surge, driven by strong
job growth, population gains and ongoing demand for urban,
amenity-rich living environments. In 2024, Texas delivered nearly
97,000 new multi-family units-more than any other state-with
Dallas-Fort Worth and Houston ranking among the top metros nationally
for new construction.
Other Texas cities are also making significant strides in the multi-family sector:
- Dallas-Fort Worth continues to top the nation in new apartment deliveries, fueled by business relocations and a steady influx of residents.
- Houston is close behind, with robust multi-family construction and a focus on both luxury and workforce housing to meet diverse renter needs.
- Austin remains a magnet for young professionals and tech talent, supporting high occupancy rates and ongoing multi-family investment.
Texas leads the build-to-rent trend with thousands of single-family rentals in development across suburbs. Demand for Class B and C apartments remains strong among families and middle-income renters. Investors and property managers in Texas’s top metros trust US Mail Supply’s mailbox solutions to match today’s tenant expectations and USPS standards.
