Our History

TRA world wide standards influence.

TRA blazed the trail to standards achievement with the industry, both in the U.S. and around the world.

TRA began in 1967 when there were no industry-wide standards, no cohesive body of government regulations, and no one else for manufacturers to turn to for help. With an original staff of three employees, TRA offered limited services to clients throughout the United States.


But our vision was grander.


In 1997 T.R. Arnold & Associates, Inc. became an Employee Owned Company. Today we serve all of North America, Europe, and Pacific Rim. Our corporate headquarters is located in Elkhart, Indiana with members of our inspection staff located in many states throughout our service area. With this approach, we can offer prompt and efficient service to our established clients as well as meet the demand for new clients.

Our Staff

Our personnel demonstrate the unequaled value of industry experience. Their skill sets reflect all aspects of the industrialized housing market. We compliment those skills with the latest in computer systems and other tools so that all their experience pays off for you.
