An ADU is a building on your property that can be either independent from or attached to your primary residence. An ADU can be used for a variety of things, including a home office, a guest house, and even long-term habitation.
ADU is a desirable alternative if you want to be close to someone in your family but yet want them to have privacy, such as an aging parent or an adult child who has returned home after college. Another desired aspect is the ability to generate semi-passive rental income without needing to own a separate property. Know your local laws, especially if you plan to rent the ADU on Airbnb, and receive a reliable estimate of the project’s cost before moving further.
