Rancho Santa Fe has restrictions that set it apart from most other communities. There are no traffic signals, and there are no streets that are wider than two lanes. Many streets outside of the downtown area are lined with landscaping, although on side streets the landscaping of individual properties serves as ample ambient decor. Very few homes are visible from outside of their respective properties.  Click here to go to the Rancho Santa Fe official website.
