Centralized Mail Delivery System Accessibility at Dormitories and Family Housing
I know what you’re thinking. WHAT is a centralized mail delivery system? In short, it is the mail room in a dormitory, multi-family housing, or commercial building. It is also what you see at the local post office. A centralized place where many individuals or agencies can receive their mail and deposit outgoing mail. And you won’t believe how complicated these installations can get when it comes to accessibility. The photo on the right is representative.
Multiple sources regarding design accessibility can apply to a centralized mail delivery system installation. These sources can include the Americans with Disabilities Act (ADA), Fair Housing Act (FHA), ANSI 117.1 building code, International Building Code (IBC), United States Postal Service (USPS) STD-4C Guidelines, USPS Postal Operations Manual (POM), USPS National Delivery Planning Standards: A Guide for Builders and Developers, and local code amendments.
Housing at a place of education, like a dormitory, must comply with the provisions of the 2010 ADA Standards applicable to transient lodging. Accessibility for these public and common use areas requires an accessible route to include a turning space if the mail room is enclosed, accessible features [reach ranges, clear spaces, and counts] such as mail boxes, accessible counters [height, depth, knee/toe clearance], and absence of protruding objects in the mail room. Some of those Standards are listed below.
2010 ADA Standard 228.2, [Depositories, Vending Machines, Change Machines, Mail Boxes, and Fuel Dispensers] Mail Boxes
2010 ADA Standard 809.2, [Residential Dwelling Units] Accessible Routes
2010 ADA Standard 809.2.1, [Accessible Routes] Location
2010 ADA Standard 809.2.2, [Accessible Routes] Turning Space
2010 ADA Standard 904.4, Sales and Service Counters
Of particular interest in the list above is the need for a turning space if the mail room is enclosed. The diagram below is representative of a the options for a turning space.
The Fair Housing Accessibility Guidelines require public and common use areas and facilities in covered multifamily housing developments to be accessible to people with disabilities so they may benefit from and enjoy the amenities present in the housing development in which they live. These public and common use areas include the mail room, or mail box areas.
ANSI does not provide a standard specifically for mail rooms or mail boxes. Designers should consult human factors and performance specifications to design accessible features.
The USPS STD-4C installation requirements include:
At least one customer compartment shall be positioned less than 48 inches from the finished floor.
No parcel locker compartment (interior bottom shelf) shall be positioned less than 15 inches from the finished floor.
No patron (tenant) lock shall be located more than 67 inches above the finished floor.
No customer compartment (interior bottom shelf) shall be positioned less than 28 inches from the finished floor.
The USPS Arrow lock shall be located between 36 and 48 inches above the finished floor.
A parcel locker requirement of 1:10 – or one parcel locker for every ten mailbox customer compartments. However, this ratio may not be applicable if there is another method of accepting USPS parcel deliveries such as a staffed service desk. And, depending on the tenants in the facility, a lower ration such as 1:6 may be prudent.
