M Noorigian Construction Co. provides garage conversion and accessory dwelling unit construction services throughout Los Angeles and Ventura County, including detached and attached ADUs, garage conversions, layout changes, interior build-outs, and coordinated multi-trade construction.


Whether you’re creating additional living space, a guest unit, home office, or rental space, we help organize the project from the initial walkthrough through completion.

ADUs & Garage Conversions

Make Better Use of the Space You Already Have

Garage conversions and ADUs can create valuable additional space without changing the way the main home is used.

We help coordinate the layout, structure, finishes, utilities, and related construction so the new space feels intentional, functional, and connected to the property.

What We Can Help With

Garage conversions and ADU projects often involve several trades, structural considerations, and detailed planning.

From Planning to Completion

We start by reviewing the existing property, discussing how you want to use the space, and looking at the conditions that may affect the project.

From there, we help organize the scope, materials, finishes, and construction sequence so the project has a clear direction before work begins.

Coordinating the Full Project

Garage conversions and ADUs often involve framing, insulation, drywall, flooring, electrical, plumbing, HVAC, cabinetry, finishes, and other connected improvements.

As the general contractor, we help coordinate the overall project and the different trades involved so the work can move forward in the proper sequence and stay organized from start to finish.
