Our ADU building process begins with a thorough on-site assessment to evaluate your property and specific needs. This informs the design phase, where we develop detailed plans tailored to your existing home and lot. We then manage the permitting process, ensuring compliance with Missouri's building codes and Columbia's local zoning ordinances.

Construction involves site preparation, foundation work, framing, utility installations, and interior finishing. We account for Missouri's seasonal weather variations to optimize the construction timeline and ensure the ADU is designed for year-round comfort and energy efficiency. When selecting an ADU provider in Missouri, look for a company with a clear, step-by-step methodology and experience working with local building departments.
