Evaluate the building you have
Not every garage begins at the same baseline. We review the permitted structure, foundation or slab, roof and walls, water exposure, available headroom, and its relationship to property lines and the main house.
Transform existing space
Garage Conversion ADUs in Los Angeles
A garage conversion ADU turns an existing accessory structure into an independent home with sleeping, cooking, bathing, and living space. The project must address the garage’s structure, slab, ceiling height, moisture, insulation, utilities, light, ventilation, fire separation, and safe access—not simply add finishes.

What this service includes
A garage conversion ADU turns an existing accessory structure into an independent home with sleeping, cooking, bathing, and living space. The project must address the garage’s structure, slab, ceiling height, moisture, insulation, utilities, light, ventilation, fire separation, and safe access—not simply add finishes.
Make it feel like a home
Garage proportions can be challenging. Good conversions place openings, storage, utilities, and rooms carefully so the old vehicle space is no longer legible.
- Private and weather-protected entry
- Natural light without sacrificing privacy
- Compact kitchen and bath planning
- Insulation, ventilation, heating, and cooling
Plan the hidden work
Sewer routing, electrical capacity, water heating, fire separation, waterproofing, and structural upgrades often influence the budget more than decorative finishes. Those systems need an early plan.
Planning guidance
Cost and timeline depend on the property.
We do not advertise a fixed price or deadline before understanding the site and scope. These are the factors that usually deserve the earliest attention.
Primary cost influences
- Existing structural condition
- Slab and moisture work
- Sewer and utility routing
- New window and door openings
- Kitchen, bathroom, and mechanical systems
Timeline guidance
A conversion may avoid some ground-up work, but investigation and approvals still take time. The schedule depends on existing conditions, design scope, utility work, and the reviewing jurisdiction.
Is a garage conversion always cheaper than a detached ADU?+
It can reduce some foundation, framing, and exterior work, but major structural repairs, slab changes, difficult utilities, or a poor existing building can narrow the difference.
Can I keep part of the garage for storage?+
Sometimes. The layout, required living facilities, fire separation, access, and local rules determine whether a partial conversion is practical.
Will the converted garage need new windows?+
Most comfortable conversions need a deliberate daylight and ventilation strategy. New openings must be coordinated with structure, privacy, property lines, and code requirements.
