    Simple. Affordable. Fast.

    Whether they are guest houses, home offices, studio spaces, or extra spaces for family, ADUs (accessory dwelling units), are becoming increasingly popular.  They are a way to get the space you need without the hassle of moving.  At ADU DIGGS, we make it easy.  Our prefab ADU drop in solution lets us handle everything from design through build (and permits) at our facility and place it in your backyard with minimal connections and finishing steps required.  

    Go from wishing it to living it in just a few weeks.


      Welcome to Your Comfort Zone

      Our easy prefab ADU process removes all the stressy unknowns.  A tightly controlled factory process ensures consistent quality, avoids long delays, prevents cost over-runs, and we handle all of the permits necessary.

      Quality You Can Trust

      ADU DIGGS teamed up with superstar local architects amk Studios and Rhino Construction to develop a prefabricated ADU that fits seamlessly into our character filled older neighborhoods. 

      Installed on a traditional raised foundation, our feature rich units employ an innovative floor plan designed to fit into our most common backyards.

      Arrives Nearly Complete

      Your ADU DIGGS arrives nearly finished, complete with AC, heat, plumbing, electric, kitchen cabinets and counters, appliances, bathroom, plumbing fixtures, lighting, and floor coverings. Most of the permitting and inspections are already done – installation is dramatically faster than a normal construction process. 

      Our building process (during a non-COVID time) is complete in just a few weeks.
