Reviews

What Los Angeles homeowners say.

"Jcs added a 400 sq ft master suite over our garage in six weeks. City inspector passed every stage on the first try. The stucco blend is invisible to the old walls."

David R.
Master Suite Addition

"They turned our cramped 80s kitchen into an open cookspace with a 10-foot island. Lighting plan eliminated every shadow. We cook more than we eat out now."

Lisa M.
Kitchen Remodel

"Our detached ADU rents for $2,800 a month. Jcs handled sewer, electrical, and even the mailbox. Tenants moved in the week we got the certificate of occupancy."

Carlos T.
ADU Construction
