#2 Better Together Builders

Better Together Builders is a Los Angeles-based contractor offering remodeling services. While they advertise ADU construction, their portfolio is more broadly focused on kitchen and bathroom remodels

#3 New Dawn Constructions

#6 Citywide Remodeling

#7 LA Dream Builders

LA Dream Builders is a residential contractor that handles a variety of projects. While they mention ADUs, there is limited public detail on their ADU-specific projects, client results, or permitting expertise. Homeowners seeking a proven ADU specialist may prefer a contractor with a stronger ADU portfolio.
