Regents Residence Hall was built in 1990 by Kahler Slater Architects as an addition to what was then RWJ (today's Viets Tower). Thanks to a $2 million gift from B´ÎÔª Regent Dr. John A. Mellowes and his wife Linda Mellowes, upgrades have been made to Regents Hall including air conditioning, lobby and new furniture. The residence was officially renamed to Mellowes Hall in their honor.

Mellowes Hall connects with Viets Tower and features a TV and vending machine lounge, laundry room, and study lounge. The Public Safety Department is located on the ground floor.
