After receiving approval from the city, I received multiple bids for my 650 square feet ADU. After screening through many GCs, I decided to go with DERCO and I highly recommend them to others! Derek and his crew were quick, reliable, and did an awesome job. The construction time took around 4 months and I was really happy how it turned out. Thanks to the Derco team!
