Garage Conversion ADU

About Our Garage Conversion ADU Services

A garage conversion ADU transforms your existing garage into a fully permitted, habitable living space. This is the most affordable and fastest path to adding an ADU because the basic structure - foundation, walls, and roof - already exists. California law explicitly protects your right to convert a garage to an ADU, prohibiting cities from requiring replacement parking or denying the conversion based on parking concerns.

CCS Inc. has completed hundreds of garage conversions across Los Angeles, Orange, and Ventura counties. Our process includes structural evaluation of the existing garage, architectural plans for the new layout, and full build-out including insulation, drywall, flooring, electrical, plumbing, HVAC, kitchen, and bathroom. We also handle raising the floor to meet habitable-space height requirements and adding proper egress windows.

Garage conversions typically cost 40-60% less than new construction ADUs and can be completed in as little as 3-5 months. They are ideal for homeowners who want to start generating rental income quickly without the extended timeline and higher cost of ground-up construction. Most converted garages yield $1,500-$2,800/month in rent throughout LA County.
