About Us

Our Mission

We are the “one-stop shop” for high-quality, innovative, affordable, energy-efficient homes constructed with proven technologies that minimize build time, noise, pollution and maintenance. We believe in the necessity for new home construction to enhance the sustainability, safety and quality of life for the people of Hawaii and beyond.

We are motivated to provide as many housing opportunities as possible for local families. We strongly believe in the numerous individual and community benefits created through the development of Accessory Dwelling Unit options on our island home.


Our Vision

The OHANA KIT was borne out of a deep desire to provide innovative, affordable homes for the good people of Hawaii and beyond. The core team at Hawaii ADU had spent many years designing and developing NuHouse.us. What emerged from that work was an opportunity to do something that no one had done before: offer prefabricated, purpose-built modular homes that can be installed in a few short weeks, accessible to virtually anyone with property and reasonably good credit. The result is the OHANA KIT!

Our Approach

From the first day of contacting Hawaii ADU to the first day that your ADU is livable, we will work with you to make the process as simple and efficient as possible. We want you to understand the options, benefits and choices that are available to you with ADU’s so that you can maximize space on your property. Our services cover every phase of buying an ADU from proper zoning, legal permitting paperwork, ADU customizable options, installation of the unit, electrical connection, plumbing attachment, maintenance of the unit and even rental management of the unit.
