You may not see your contractor license number because:
1. You're in the system but your license expiration date was not updated. You can email customer service (permitsonoma-customerservice@sonoma-county.org) to update the system and include the CSLB number, the new expiration date.
2. We don't have your contractor's CSLB information in the system.
To add you, contact a Permit Sonoma permit tech at 707-565-1900 or you can email permitsonoma-customerservice@sonoma-county.org.
In your email, please include your CSLB number for verification purposes.
