Our Services
We provide garage conversion and ADU design and construction services across Los Angeles and select nearby communities, including the San Fernando Valley, Calabasas, Santa Clarita, Pasadena, and surrounding areas.
Your garage is often the most underused space on your property. In Los Angeles, it can become a fully legal ADU that generates rental income, adds living space, and increases property value. Many homeowners continue using garages for storage while missing a major opportunity an unused structure becomes an ongoing cost instead of a productive asset.
Green Star Remodeling converts garages into fully permitted ADUs designed for real living and long-term value. We evaluate your existing structure and design a conversion plan that maximizes usable space, handle LADBS permitting, structural planning, and full code compliance, and build complete living units with kitchens, bathrooms, and independent utility systems. Every project is managed from design to final inspection by a licensed contractor with over 20 years of experience.
Many homeowners pair garage conversions with broader ADU construction planning to align unit type, layout, and rental strategy with the rest of the property.
Full transformation of an attached or detached garage into a permitted living unit. Includes structural work, insulation, drywall, flooring, kitchen, bathroom, electrical, and plumbing for a complete independent space.
Conversion of an attached garage into a smaller legal unit up to 500 sq ft with an efficiency kitchen and bathroom setup. A cost-effective option for rental income or family use.
Architectural plans, structural engineering, Title 24 compliance, and full LADBS permit submission. We manage the entire approval process to reduce delays and revisions.
Service panel upgrades, sub-panels, EV-ready wiring, lighting, and full electrical systems installed to code. Required for most garage conversion ADUs in Los Angeles.
Complete plumbing for kitchens, bathrooms, and laundry areas. Includes water heaters, sewer connections, and utility coordination for fully functional living spaces.
Energy-efficient mini-split systems, insulation upgrades, and weather sealing designed for year-round comfort and Title 24 compliance in Los Angeles climate conditions.
New private entrances, doors, windows, exterior finishes, and pathways designed to make the ADU fully independent from the main home.
Complete demolition and rebuild of the existing garage when structural or utility conditions require a full reconstruction approach.
A garage conversion ADU can generate steady rental income while increasing long-term property value. High housing demand across Los Angeles makes ADUs a strong investment for homeowners and investors.
ADUs provide flexible space for family members, guests, or home offices. They turn unused garages into functional living units that support today's lifestyle needs.
Los Angeles ADU laws have become more flexible, making garage conversions easier to permit and build. Streamlined approvals and updated zoning rules have improved project feasibility across the city.

All garage conversion ADU projects in Los Angeles are framed, insulated, and finished to California Title 24 energy compliance standards.
