For those of you interested in ADUs, my website, “Silicon Valley ADUs,” ( is a new online resource featuring news about ADUs, as well as an FAQ on ADU basics. I have also provided online tools to assist those of you who are ADU developers: The Excel-based “Return on Investment” tool has a template that is designed to help plan ADU projects and track costs, while the “Regulations” section will help you identify the relevant ordinances applicable to your project for the Santa Clara County jurisdiction in which the project is located. Finally, I have included a forum for you to give references for local ADU project vendors you have experienced; as you successfully work with these vendors, I hope you will share your thoughts with me.
