Thoughtfully Designed Space, Built With Clarity From Day One An ADU is more than extra square footage. It’s a fully integrated living space that requires careful planning, coordination, engineering, and long-term thinking from the very beginning. At The Carpenter’s Son, we approach ADUs, garage conversions, and major additions with a structured planning-first process designed to create clarity before construction begins. From zoning and setbacks to utilities, permitting, and long-term performance, these projects require disciplined coordination across multiple trades and systems — exactly the kind of work we’re built for. You’ll work directly with the owner throughout the process, alongside trusted licensed professionals coordinating under one system and one standard. Our goal is to keep projects organized, realistic, and moving forward with accountability at every phase of construction. Every ADU project begins with a professional pre-construction planning process.
