ADU CONSTRUCTION

Lee & Company Construction provides complete ADU construction services for homeowners looking to add living space, create rental income, or build a private unit for family. From planning and permitting to construction and final inspection, we manage the process with clear communication, organized scheduling, and experienced contractor oversight.

ADU Planning & Feasibility

Every successful ADU starts with a clear plan. We review your property, project goals, access, utilities, layout options, and construction approach to help determine the best path forward. Whether you are considering a detached ADU, garage conversion, addition, or attached unit, we help identify the scope before construction begins.

Design, Plans & Permitting

Our team coordinates the plan development and city submittal process so your ADU is properly prepared for review. We work with designers, engineers, and city departments to move the project through planning, corrections, approvals, and permit issuance as smoothly as possible.

Full ADU Construction

Once permits are approved, Lee & Company Construction manages the build from start to finish. This includes site preparation, foundation work, framing, roofing, windows, doors, electrical, plumbing, HVAC, insulation, drywall, stucco, and all major construction phases required to bring the ADU to life.

Finishes, Final Inspection & Turnover

We complete the project with interior finishes, cabinets, countertops, flooring, tile, paint, fixtures, final utility connections, and inspection coordination. Our goal is to deliver a finished ADU that is clean, functional, code-compliant, and ready for use.
