Oahu Homes with Ohana Units: The Ultimate Guide

Are you considering buying a home on Oahu with an ohana unit? You’re not alone. Ohana units, also known as in-law units or auxiliary dwellings, are increasingly popular among homebuyers in Hawaii. In this article, we’ll explore the benefits and challenges of owning an Oahu home with an ohana unit, as well as the latest trends and regulations surrounding these units.

What is an Ohana Unit?

An ohana unit is a separate living space on a single-family residential lot. It can be a detached unit, attached to the main house, or even a converted garage. Ohana units typically have their own kitchen, bathroom, and bedroom, and are designed to provide additional living space for family members or renters.

Benefits of Ohana Units

Ohana units offer several benefits to homeowners, including:

Increased Property Value

One of the biggest benefits of an ohana unit is the potential to increase your property value. According to a study by the University of Hawaii, ohana units can increase property values by up to 15%. This is because ohana units provide additional living space, making your property more attractive to potential buyers.

Rental Income

Ohana units can also provide a steady stream of rental income. If you’re planning to rent out the unit, you can earn passive income to help offset your mortgage payments.

Flexibility and Convenience

Ohana units offer flexibility and convenience for homeowners. You can use the unit as a guest house, home office, or even a space for your extended family.

Challenges of Ohana Units

While ohana units offer many benefits, there are also some challenges to consider:

Zoning Regulations

One of the biggest challenges of ohana units is navigating the complex zoning regulations on Oahu. The City and County of Honolulu has specific rules governing the size, location, and design of ohana units.

Construction Costs

Building an ohana unit can be expensive. Homeowners need to consider the cost of construction, including materials, labor, and permits.

Property Management

Managing an ohana unit can be time-consuming and requires additional responsibility. Homeowners need to consider the logistics of renting out the unit, including finding tenants, collecting rent, and handling maintenance.

Regulations on Ohana Units

There are several regulations that homeowners need to be aware of when building or renting out an ohana unit:

Bill 7

In 2019, the City and County of Honolulu passed Bill 7, which relaxed the regulations on ohana units. The bill allows homeowners to build ohana units on smaller lots and eliminates the requirement for a minimum of four parking spaces.

State Law
