Looking
to build an ADU California? Superior
ADUs is the place to be. We help our
clients build a California ADU in their backyard. With Superior ADUs you’ll have more space,
more income, and more possibilities. But
first, let’s make sure we’re on the same page.
What is an ADU?
ADU stands for accessory dwelling unit. Other names include mother-in-law units, granny flats, casitas, and guest houses. Each accessory dwelling is considered a secondary housing unit from the main single-family house, meaning you can rent them out. There are many different types of ADUs, such as garage conversions, detached or attached units, along with numerous others, each meant to serve different purposes.
Why Build an ADU?
- Rental Income – Rent out the ADU or move into the ADU and rent out the main house.
- Ease of Financing – Use the equity in your home to build the ADU, rent it out, and make additional income.
- Multi-Generational Family Living – Allow family members to stay in the ADU, keeping them close, while giving them independence.
- Extra Space – Use the ADU for that extra space you need, like a home office or studio space!
The Benefits of Having an ADU
An ADU adds value to your property. You are essentially adding square footage to your residence at a cost that is less than the value you’ll gain. New laws have recently passed in California allowing homeowners to build an ADU and a Junior ADU on their property. This means that you could rent out the main residence or ADU to one family and the Junior ADU to someone looking for a studio apartment. You could potentially have multiple rental incomes from one property! Whether you plan to live in the ADU or not, the potential for rental income makes having an ADU, or two, worth it.

An ADU also adds square footage! You are basically building a second home onto an existing property, creating room for elderly parents, adult children or extended relatives. All of our ADUs are built with curbless showers and at least 32” doors, so the disabled and elderly have easy access. Adding an ADU also benefits remote workers who need an office or meeting space at home.
