How to Renew Your California Contractor License (CSLB) in 2026
If you hold a California contractor license, the CSLB requires you to renew it every two years (active licenses; inactive licenses run four years). Miss the deadline and your license becomes delinquent — and any work performed while it's expired can be treated as unlicensed, which carries real penalties and can jeopardize your ability to collect payment.
When it's due
Your license expires on the last day of the month, two years from your last renewal. The CSLB typically mails a renewal notice about 60 days before expiration — but don't rely on the mail; treat it as a backup.
How to renew
Renew online through the CSLB's licensing portal (sole-owner licenses can renew online; others may need the mailed form). You'll confirm your bond and workers' comp status and pay the renewal fee. Keep your contractor bond and insurance current — a lapse there can stall your license renewal.
What trips people up
The two-year cycle is easy to lose track of, especially when your insurance and bond renew on different dates. The fix is simple: put the exact expiration date on your calendar and set reminders at 60, 30, and 7 days before it.
