Detached ADUs for California Properties
For homeowners with unused outdoor space, a detached ADU can become a guest house, a private office, a rental opportunity, or an extension of your household. We design and build backyard homes that integrate seamlessly with your main residence and comply fully with California’s zoning rules, setback requirements, and energy standards. Each detached ADU is crafted to feel like a true home, complete with thoughtful layouts that support privacy and comfort.
Garage Conversions & Basement ADUs
Extra square footage in California is valuable, and converting existing structures is one of the smartest ways to maximize it. We transform outdated garages and unfinished basements into warm, comfortable, and fully code-compliant living spaces. Our work includes addressing moisture, soundproofing, insulation, structural updates, and efficient space planning. These conversions blend practicality with style, offering a high-performing ADU without expanding your property’s footprint.
Prefab ADUs Designed for California Living
For homeowners looking for a more streamlined or budget-friendly approach, our prefab ADU options offer modern design paired with accelerated installation timelines. These units come with curated floor plans, pre-selected finishes, and structural components that meet California’s strict building and energy codes. Prefab ADUs are ideal for those who want a beautiful, predictable result delivered faster than a traditional build.
ADUs for Multigenerational Living
California families are increasingly turning to ADUs to bring relatives closer while still maintaining independent living arrangements. We design ADUs that promote togetherness while ensuring privacy, comfort, and accessibility. With thoughtful floor plans and flexible layouts, these units support aging parents, returning children, extended family, or caretakers, helping everyone stay connected without sacrificing personal space.
What Sets Our California ADUs Apart
Our deep understanding of California zoning regulations, height restrictions, SB-9 updates, and local permitting processes allows us to move ADU projects forward with fewer delays and clearer expectations. Every ADU begins with a design that reflects how you truly want to use the space, whether it’s for living, renting, working, or hosting. From the first sketch to the final walkthrough, we handle everything in-house, making communication easier and timelines more reliable.
Quality is at the heart of every ADU we build. Our materials, craftsmanship, and construction standards are chosen to withstand California’s climate, seismic requirements, and long-term wear. As a licensed, bonded, and insured contractor in California (License #1119646), we ensure that every ADU meets the highest standards of safety, durability, and performance.
