OHANA KIT: The total package for discovering, financing and installing your dream ADU—quickly and easily.

In the Fall of 2015, Hawaii passed legislation to address Oahu’s housing crisis. Following in the footsteps of select cities in California, Oregon, Washington State and others, Accessory Dwelling Units (ADUs) were legalized for Oahu homeowners. The new law permits ADUs to be rented long term. Homeowners looking to downsize can also move into a new OHANA KIT ADU while maximizing the rental income potential of their primary house.

On Oahu, ADUs may be permanently installed small homes no larger than 800 square feet for properties over 5,000 square feet, and 400 square feet for properties between 3,500 and 5,000 square feet. They may be fully detached structures featuring a full kitchen, bathroom and bedrooms. The OHANA KIT by Hawaii ADU has been designed to comply specifically with new regulations in Hawaii, and across the United States to make every homeowner’s ADU a low stress and lucrative endeavor.

The Opportunity

If you live on a residential-zoned property larger than 3,500 square feet, you may be eligible to build an additional small house called an Accessory Dwelling Unit or ADU.

Hawaii ADU simplifies the process of buying and installing a low maintenance, high performance ADU, which will add significant value to your property the day it’s installed.

With the potential to generate $10,000 to $15,000 of additional income annually (or as much as $250,000+ over the next 25 to 30 years), eligible Oahu homeowners have an unprecedented investment opportunity in their own yards.
