We had a TERRIFIC experience with Charlie at CALI ADU. He was efficient, communicative and provided us with great blueprints for our garage conversion. Whenever the city had corrections, he was right on top of it responding and resubmitting. Highly recommend working with him.
I am so happy we chose CALI ADU to design and build our garage ADU. Charlie Melvin is exactly as easy to work with as he seems when you first meet him.
The consistent communication is so appreciated, and the outstanding quality of their work is exactly like the pictures we saw in the CALI ADU online portfolio.
We worked with Charlie from CALI ADU, who we engaged to draft our ADU. Initially, we worked with him to draft the ideas, but ultimately determined he was the best person to carry out the work. Charlie is professional, and he was always accessible when we had questions. He is adaptable and patient with changes. My wife and I highly recommend Charlie.
