Popular ADU Types and Garage Conversion Solutions
Garage conversion projects represent one of the most cost-effective ways to add living space to your property. This approach utilizes existing structure while transforming underutilized space into a functional dwelling unit. Popular garage conversion options include:
Single-Car Garage Conversions: Perfect for studio-style ADUs in cities like Pasadena, Glendale, and Burbank. These typically range from 240-400 square feet and work well for single occupants or couples.
Two-Car Garage Conversions: Ideal for one-bedroom ADUs in areas like Torrance, Irvine, and Newport Beach. With 400-600 square feet, these units can accommodate full kitchens, separate bedrooms, and comfortable living areas.
Detached ADU Construction: When garage conversion isn’t suitable, new detached units offer maximum flexibility. Popular in cities like Santa Monica, Beverly Hills, and Anaheim, these units can be customized to match your main home’s architecture while providing complete privacy.
