Full-Service Prefab ADU Builder in California
LiveLarge Home is a full-service accessory dwelling unit builder offering a white-glove prefab ADU solution currently available in California. As a comprehensive ADU contractor, they handle everything from permits and installation through to final inspections — making the process as seamless as possible for homeowners looking to expand their living space without moving or purchasing a new property.
One of the standout advantages of working with this backyard cottage builder is speed. Their streamlined on-site build process can have a backyard home ready in as little as 4–6 weeks, compared to the industry average of 7–9 months for a traditional ADU build. Their fixed pricing starts at $412 per sq. ft., significantly below the market average of $500–$550 per sq. ft., making them a cost-competitive choice for homeowners.
Their ADUs are also designed with sustainability in mind. Each unit is built with a light steel frame structure, triple-pane windows delivering up to 40% more natural light than most market alternatives, optional solar panel arrays, smart home controls, fire-resistant materials, and energy-efficient systems — all working together to reduce reliance on the grid while maximizing comfort.
