Each ADU is designed to maximize space, functionality, and long-term value, whether for personal use or investment.
Every ADU project begins with a vision. We work closely with you to design the ideal accessory dwelling unit layout, determining the best size, floor plan, architectural style, and interior finishes to maximize both functionality and property value.
Our team prepares the architectural plans, engineering drawings, and permit documentation required by the city. We handle the full ADU permitting process, ensuring the project complies with Los Angeles building codes and zoning regulations.
If the project involves a garage conversion or site preparation, we carefully remove existing structures, clear the space, and prepare the property for construction while protecting the surrounding home and landscaping.
During this phase we begin construction of the ADU structure including foundation work, framing, roofing, electrical systems, plumbing systems, insulation, windows, and exterior finishes, creating a strong and modern new living space.
The interior finishes bring the ADU to life. We install custom kitchens, modern bathrooms, flooring, cabinetry, lighting, appliances, and storage solutions, ensuring the space feels comfortable, stylish, and fully functional.
Before final delivery, we conduct a full inspection and quality check to ensure everything is completed to the highest standard. Your new ADU is fully finished, city-approved, and ready for living or rental use.
