On December 12, 2017, the Board of Supervisors adopted an update to the County’s Subdivision Regulations to incorporate changes made to the California Subdivision Map Act and to reflect pertinent case law. In addition, the update clarifies and streamlines the regulations and the subdivision process to make them both more user-friendly.

The 2017 Subdivision Regulations are not effective in the Coastal Zone. Until these regulations are certified by the California Coastal Commission, the 1992 Subdivision Regulations remain in effect within the Coastal Zone.
