Reviews

What Los Angeles homeowners say.

"MDM added a 450 sq ft master suite over our garage. They matched the stucco perfectly and kept dust contained during the entire build. Passed final inspection on the first try."

Rosa M.
Master Suite Addition

"We turned our detached garage into a rental ADU. MDM handled the sewer tie-in, electrical panel upgrade, and city inspection schedule. Now we collect $2,400 a month."

David L.
Garage to ADU Conversion

"Opened up our galley kitchen into one big room with an island. The crew protected our hardwood floors and cleaned up nightly. Finished four days early."
