ADU Construction That Adds Value and Flexibility to Your North County Home
Whether you’re planning to generate rental income, provide independent living space for aging parents, create a home office, or add long-term value to your property, an accessory dwelling unit gives you options. We design and build ADUs across Carlsbad, Encinitas, Poway, Solana Beach, and throughout North County San Diego including: detached units, garage conversions, and attached ADUs that meet all local building codes and zoning requirements. From initial site evaluation to securing permits and managing all aspects of construction, our design-build team handles every step of the process.



From Simple Guest Houses to Custom ADU Projects, We Build What Works for Your Family
Some homeowners want to maximize existing space through garage conversions or attached ADU additions. Others prefer a ground-up detached unit that feels like a truly separate residence. Any ADU—attached or detached—can incorporate modern finishes, functional kitchens, well-designed bathrooms, and thoughtful layouts. As a licensed contractor, we handle projects of all sizes and complexity levels – from 400-square-foot studios to 1,200-square-foot two-bedroom units. We can help with your ADU project in any North County community. You get a well-built, permitted ADU that enhances your property – designed and constructed with care by our trusted design-build team.
