The idea of transforming a vacant garage into an ADU may sound simple until you start thinking about the permits, structural requirements, utilities, design, and construction. It might take more effort than anticipated before an older garage can be turned into a safe living space.

It is also important to identify a builder who knows the needs of Los Angeles and can handle the project effectively. Comparing local builders can help you determine which services, designs, and construction methods suit your property.

The proper builder can survey your garage, discuss what must be different, and take you through the design, permits, and construction. However, each company handles ADU projects differently, so it helps to review their services before making a decision.

There are a number of garage conversion builders within Los Angeles who offer varying services and project strategies. The five companies listed below are worth considering when comparing your options and planning your garage conversion.

1. Go ADU

Abodu takes a different approach to ADU projects. The company focuses on prefab backyard homes and ADUs rather than garage conversions. Its factory-built models range from a 385-square-foot studio to a 1,195-square-foot three-bedroom unit. Abodu also handles property checks, design support, permits, construction, and installation.
