New Solar Panel Permitting Process

The City of Thousand Oaks has launched an efficient solar panel permitting process for licensed contractors needing to obtain permits on residential properties in accordance with SB379. This permit is for solar panels and battery permits of 38.4 KW or less.

 Our pilot program launched on September 1, 2023, through September 30, 2023, for participating contractors. Thank you to those who participated! This program is now available for all electrical licensed contractors.


Installing solar panels on a new or existing building requires a permit from the City of Thousand Oaks Building & Safety Division. This page provides guidance on options and systems to ensure your panels will be installed in the safest and most effective way. 

The State of California Solar Permit Guidebook can help develop the necessary documentation to effectively install a safe system and efficiently obtain a permit.
