Field notes
The guides are grouped by costs, money, design and build, rules and permits, and site work, with examples including utility connections and HOA restrictions. The homepage cites a 2021 UC Berkeley Terner Center owner survey and the CA HCD ADU Handbook; it also displays a California ADU permit figure for 2024. Quote requests ask for a ZIP code, project type, and start timing, and the site describes a follow-up by email.
