Unlike most buildouts, tenant improvements require a certain level of skill and craftsmanship, given the very specific rooms that need to be designed, then crafted. Business owners face the challenge of finding a contractor that will best meet their project’s needs, and meet those needs on tight schedules that will provide as little interruption to normal business operations as possible.

This list compiles 15 of the best tenant improvement contractors in Indianapolis. We chose these firms based on merit, experience, and prior projects. Given these firms’ excellent skills and craftsmanship, it’s no surprise that several of their most notable projects can also be found in a number of locations across the country.
