When we learned about the opportunities available through SB 9, we were excited but overwhelmed by the complexity. Build By Design stepped in and made the process clear, manageable, and even enjoyable. They helped us split our lot and design two beautiful, sustainable homes—one for us and one as a rental property. Their team handled everything from permitting to construction with incredible attention to detail and a deep understanding of the SB 9 guidelines. Thanks to them, we’ve increased the value of our property and created long-term income for our family. We couldn’t be happier with the outcome!
