Newport Beach ADU is here to guide you on your accessory dwelling unit journey, no matter where you are in the process.

Building an ADU can be overwhelming. Our resources help you find inspiration, navigate the process, and build your ideal ADU.

Building an ADU benefits homeowners and the community

Building and renting an ADU is truly a community service ā€” ADUs often provide homes for the local workforce and small families who have difficulty finding local housing that meets their needs. ADUs also house teachers, essential workers, and community members who otherwise may have to commute long distances from home to work. 

For homeowners, there are many reasons to build an ADU ā€” rental income, safe and convenient housing for relatives, flexibility over time, and many others. An ADU on your property can bring substantial benefits to your life.
