Every ADU project begins with a professional consultation where our Los Angeles ADU builders evaluate your property, zoning regulations, and backyard space. We discuss your goals, budget, and potential ADU designs including detached ADUs, garage conversions, and junior ADUs. This step ensures your project is feasible, compliant with city regulations, and aligned with your long-term investment plans.
