Accessory dwelling units, or ADUs, are small, self-contained living spaces that are built on the same property as a single-family home. ADUs are also known as granny flats, in-law units, or secondary suites. They are becoming increasingly popular as a way to add affordable housing to neighborhoods and provide a source of income for homeowners.
Some ADUs are detached from the main living space, such as a separate guesthouse or carriage house. Others are attached ADU models, such as a basement apartment or a garage conversion. ADUs provide you with more space for your family, build the value of your primary house, and generate extra income through rentals.
We believe that this is the most common query we get, and we are aware of how crucial it is to you. Check out our feature for property evaluation. Enter your address, pick an ADU, then drag it to your backyard—that easy!

“The team at ADU Works has been incredibly responsible throughout the process. All questions that we had along the way were researched in detail and always responded to within 24 hours. It has been a real treat to be able to work with a team that does exactly what they say they are going to do.”
SIPs are made up of insulating foam cores sandwiched tightly between two structural facings that are designed and precisely manufactured off-site. Once these are completed, it only takes 30-60 days of onsite work and one contractor to complete your ADU.
A helical pile is a steel shaft with helices that is screwed into the ground to help anchor the ADU to the soil. This process requires only small machinery and a team of 2-3 people to complete in about 3 days.
Pre-engineered plan sets are ready-to-build diagrams which allows for quick, reliable & simple construction process – streamlining the need for inventorying materials or planning.
