Why Adu

The Lucrative ADU Opportunity

You might qualify to purchase an ADU with no money out of pocket through a Home Equity Line of Credit (HELOC) from your preferred banking institution.

An ADU can immediately increase the value of your property beyond the unit’s cost; in other words, with financing, the bank will essentially pay for your new ADU.

Alternatively, you can maximize the income potential of your property by moving into your ADU and renting out your primary residence.

While Hawaii ADU does not offer investment or tax advice, installing an ADU offers homeowners an unprecedented investment opportunity that can both improve your quality of life today and support your future retirement security.

What are ADUs?

Accessory Dwelling Units (ADUs) are small, separate living areas equipped with their own kitchens, bathrooms and sleeping spaces. They can be used as a residence on single-family lots or as comfortable additions to existing homes.

ADUs Create Affordable Housing

The State of Hawaii encourages the use of ADUs by waiving a majority of the ADU fees and permits because they represent a viable solution to Hawaii’s affordable housing crisis.
