Civil Code Section 1008 was added in 1965 and very directly provides that “no use by any person or persons, no matter how long continued, of any land, shall ever ripen into an easement by prescription: if the owners posts the following notice:

• Right to pass by permission, and subject to control, of owner. Section 1008 of the California Civil Code

This notice must be posted at each entrance to the property or at intervals of not more than 200 feet along the boundary. Better practice is to post both at entrances and at 200-foot intervals. The owner should maintain records of the postings, including dates and digital photographs.

These signs are often posted on fences and imbedded into sidewalks in plazas surrounding urban buildings.
