Accessory Dwelling Units, or ADUs, have become increasingly popular on the island of Oahu, as a means to address housing shortages and offer aging-in-place opportunities for homeowners. However, to successfully navigate the process of building an ADU, it’s crucial to understand Oahu’s ADU requirements specifically. In this article, we’ll break down the ABC’s of Oahu ADU requirements. We have provided you with the knowledge needed to begin your next project.
What Are the Oahu ADU Requirements?
Oahu’s ADU requirements encompass a range of zoning, building, and use regulations. To qualify for an ADU, you must adhere to these property regulations along with the very specific usage requirements. Oahu regulations differ from other areas in the US when it comes to ADUs. Follow regulations and make sure that your ADU is constructed safely.
We highly recommend that you go through these specific requirements with one of Oahu’s professional contractors– you can find more about hiring one here; but here are some basic points you should know before beginning this process:
- According to the Honolulu Government website: “An ADU can be built on any lot zoned Residential (R-3.5, R-5, R-7.5, R-10, and R-20) or Country District with a lot area of 3,500 square feet (SF) or more provided that there is adequate infrastructure and subject to meeting all other Land Use Ordinance provisions for the zoning lot and there are no restrictive covenants.”
- ADU’s can NOT be rented for less than a 6 month period– meaning these are not meant to be vacation rentals or AirBnBs
- At least one parking spot is required on the property for the ADU
