Permits & process
Orange applies design review in its historic quarters (Old Towne runs a dedicated review board), but standard residential lots follow the regular plan-check path. Matching the existing structure's exterior kept review friction low.
The build
Attached units trim the site-work bill — one shared wall, shorter utility runs — which is why they anchor the value end of the full-size ADU range.
