Success Stories and Testimonials
Our ADUs exceed the expectations of homeowners across Southern California. From spacious guest houses to cozy backyard retreats, each project showcases our commitment to quality and customer satisfaction.
Additional Space for Family Members
We recently constructed an ADU for a family in Orange County. It was built for the homeowner’s Mom, who was living in a one-bedroom, $1,500-a-month apartment 10 miles from the family. Grandma moved into the Bungalow ADU and is now closer to her daughter and grandkids. She feels safer and has more social connections. The family has a net savings of over $1,000 a month in rent. A true ADU success story!
Rental Income
A prefab ADU in California can turn a single-family rental property into a 2-income property.
This was the case with one of our customers, an investor with a single-family income property in San Diego. He put it best when he asked us, “Where can I buy a 2-bedroom rental property for under $120,000 in San Diego? Nowhere! But I could build a 2-bedroom ADU for this price – it’s a no-brainer.”
Pro Tip: The presence of an ADU can often enhance the attractiveness of a house on the market, and increasingly, investments in new ADUs are being reflected in the appraised value of those properties.

- Parking requirement for ADU waived

FAQs: ADU Builders in Southern California
Below, we’ve answered some common questions we’ve received as ADU builders in Southern California. Please contact us with any additional questions or concerns you may have.
Are ADUs allowed in my Southern California neighborhood?
Can I build an ADU? How many can I build?
If you live on a residential lot, you can build one detached ADU and one junior ADU (a unit no more than 500 sq ft located within the home). A maximum of two detached ADUs are allowed on the property if you live on a multi-family lot.
Why build a prefab ADU in California?
Building an ADU with prefabricated construction is highly advantageous, and here’s why many choose this method in Southern California. Prefabricated ADUs are constructed with precision in a factory setting, akin to the automotive industry’s production line efficiency. This process allows for better quality control, faster construction, and greener building practices than traditional site-built ADUs. The factory environment also means less disruption at your home; the main structure is set in place in just one day, minimizing on-site construction mess and noise. Subsequently, only a small team is needed to finalize details and utility connections, greatly reducing the overall impact on your property and daily life.
How long will it take to build an ADU?
It depends on how long you take to choose the style, the building code (ANSI, Local, and Federal), and the floor plan. Once the California prefab ADU plan is chosen and a contract is signed, it typically takes from 6 to 9 months to get a building permit and start the project. Much of this time is spent on the State and Local approval of the building plans. Once we have the permit in hand, the USModular team will act very fast and typically can complete a project within 3 to 6 months.
