The Planning Division is responsible for Zoning in unincorporated Sonoma County. It works to develop and implement the Sonoma County General Plan, Local Coastal Program and other adopted Area Plans or Specific Plans. It evaluates the environmental impacts of private development proposals and public projects, such as bridges, roads, and airport projects. It reviews new development proposals for conformance with the County's General Plan and Zoning Codes.
Planning is divided into two sections, with Natural Resources its own division. On this page:

Planning Division Sections
The Comprehensive Planning team leads the County of Sonoma’s long-range land use planning and policy efforts. Also known as advance planning, the work is primarily focused on creating a long term vision for the people of Sonoma County, which is directed by the county’s General Plan.
All land in unincorporated Sonoma County is guided by its General Plan, which was last comprehensively updated in 2008. Under the leadership of the Sonoma County Board of Supervisors, the team delivers a work plan that includes working directly with Permit Sonoma customers and leading a number of County initiatives through an inclusive community engagement strategy.
Natural Resources, which is now its own division, evaluates the environmental impact of public projects, such as bridges, roads, and airport projects, to comply with the CEQA and other laws and regulations that protect water quality, biotic and cultural resources. Natural Resources staff also prepares EIRs for private projects.
The Project Review section reviews new development proposals for conformance with the County's General Plan and Zoning Code Regulations. They also evaluate environmental impacts of private development proposals and coordinate with other Permit Sonoma divisions, such as building and engineering, to ensure that standards for building safety and water resources are incorporated into new development.
End of Extended COVID Permit Expiration Date
In order to support the difficulties the COVID-19 pandemic brought to the community, Permit Sonoma offered customers a two-year extension above and beyond the regular timelines for various ministerial applications and permits. The conditions attributing to the local emergency no longer exist and the Board of Supervisors is rescinding the local emergency as of May 16, 2023. As such the policy extending the expiration dates will sunset effective May 17, 2023.
