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 The conditions attributing to the local emergency no longer exist and the Board of Supervisors rescinded the local emergency as of May 16, 2023. As such, the policy extending the expiration dates was sunsetted effective May 17, 2023.
This change does not affect permits that have already been extended. All applications received beginning May 17, 2023 are valid for one year, and the COVID-19 extension will not be applied.
