Obtain Permits

Our team will immediately begin obtaining permits and scheduling appointments with the necessary trade experts to guarantee your home is in the optimal state needed to begin the ADU construction phase. Your project manager will handle this process from A to Z.

Time To Shop!

This is the fun part! Time to shop!

Step 4: Construction Phases

The initial phase of the actual construction will consist of us demolishing the area and removing all of the unwanted materials. Cleaning out the space in a timely manner will ensure that we stay on track with our ADU housing project timeline and prepare us for the framing phase.

Framing and Preparation

Preparation is a key part of a truly smooth installation process, so it is incredibly important that we inspect the space after it’s been demolished and begin the process of framing the structure. As framing is completed, we can then stucco the exterior, interior drywall, plumbing, and other aspects needed to move on to the installation phase.


It’s finally here! The installation process is where your brand new ADU or garage conversion begins to take shape and finally comes to life. Your project manager will ensure that each step is handled with care so that everything is installed in a clean and perfect manner.

What is ADU?

The ADU Los Gatos may be attached to a house or garage, or it can be built as a standalone unit. It will use the primary house’s energy and water connections. The construction of a Los Gatos accessory dwelling unit will fall under different zoning rules and regulations depending on where you reside.
