Los Gatos ADU design & construction

View the original sourceLos Gatos ADU questions
- Can I customize a Los Gatos gallery plan?
- The Town says its gallery designs cannot be modified. Discuss a custom application if the chosen design needs changes.
- What if the yard includes a creek?
- Use the watercourse screening in the Town application, including Valley Water consultation where identified; a clear-looking yard is not proof of a buildable envelope.
