Transforming an underutilized garage into a high-end Accessory Dwelling Unit (ADU) is one of the fastest-growing trends in Southern California. For homeowners in Los Angeles, Santa Monica, and beyond, a garage conversion represents the most cost-effective path to adding livable square footage.
Why Convert Your Garage?
Most Southern California garages end up as cluttered storage spaces. By converting this existing “shell,” you bypass the need for a new foundation and framing, which can save you significant time and money compared to a detached ground-up build.
The HG Design Build Process
At HG Design Build, we don’t just put up drywall in a garage. We treat a conversion like a luxury renovation. Our process includes:
- Structural Integrity: We assess the existing slab and framing to ensure it meets modern California seismic codes.
- Utility Integration: Seamlessly connecting plumbing for a new kitchen and bathroom into your home’s main lines.
- Aesthetic Continuity: We ensure the exterior of your new ADU matches the architectural style of your primary home, maintaining your property’s curb appeal.
Key Considerations for 2026
Under current California law, you are often exempt from replacing the parking spaces lost during a garage conversion if you are near public transit. This makes it easier than ever to turn that dusty garage into a high-earning rental unit or a private guest suite for family. With our 30 years of experience, we navigate the specific LADBS requirements to ensure your conversion is fully permitted and adds maximum value to your home appraisal.
