Why choose prefabricated ADUs?

Opting for a prefab ADU has many advantages over traditional construction. Time is one of the biggest benefits. These modular homes are built off-site and assembled quickly on your property, significantly reducing the building process timeline. An Abodu project can be completed in as little as nine months.


Since prefab units are constructed in a controlled environment, they are built with greater precision and higher quality control. Additionally, prefabricated ADUs are energy efficient, making them an environmentally friendly choice for your next home office, granny flat, or guest house.

FAQs about prefabricated ADUs in California

Yes, ADUs are legal in California. Statewide regulations have been passed to encourage the building of ADUs and foster a supportive environment for homeowners. Local ordinances in major cities and counties, such as Los Angeles and Southern California, define specific zoning and building code requirements.

The cost of a prefab ADU in California varies based on size, design, and location. Abodu offers a range of prefab ADU models, each with transparent pricing that includes upgrades and customization options. Factors that influence the cost include the floor plan, square feet (sq ft), materials, cabinetry, and other high-quality finishes.

According to state California law, the maximum size for a detached ADU is 1,200 square feet to ensure they integrate seamlessly into single-family properties. However, local jurisdictions and municipalities can set their own limits. Abodu's ADU models comply with these regulations, offering various options from compact studio sheds to more spacious family home additions.
