"Not Professional. Not Responsive. Poor Communication. Poor Planning."

"My husband and I moved to San diego 2 years ago, and wanted to build a granny flat in our backyard. We contacted a number of builders that said they specialized in granny flats. After doing our reserch, we were not confident with what we were hearing. A friend of ours recommended ADUplus, because they could handle the entire process. We are glad we contacted them. They fulfilled all of our requirements, at a very reasonable price. We would recommend them to anybody that wants to build a granny flat!"
