If the license carries a C-10 electrical classification, the renewal rows sit $20 above the ordinary ones. On the CSLB fee table the timely pair reads $470 for a sole owner and $720 for a non-sole owner, and the delinquent pair reads $695 and $1,070. Those four figures are four separate rows, and the twenty dollars is built into each of them rather than charged somewhere else as an add-on.
The numbers below come from https://www.cslb.ca.gov/about_us/library/fees.aspx, read 2026-11-14. They are transcribed from the table rather than derived from it. Should your notice disagree with anything here, the notice and the table govern, and the table prints 800-321-2752 for the questions this page cannot settle.
The $20 difference, measured against the ordinary rows
The ordinary active timely renewal is listed at $450 for a sole owner and $700 for a non-sole owner. Add the C-10 classification and those two rows become $470 and $720. The gap is $20 in both cases: find the ordinary row your license would use, then find the C-10 row beside it, and read the difference yourself. Doing that once is worth more than trusting any sentence on this site, including this one.
The timely pair: $470 and $720
Timely means the payment is postmarked or received on or before the expiration date, the last day of the month printed on the license. $470 is the active timely row for a C-10 held by a sole owner; $720 is the same renewal for a partnership, corporation, LLC or joint venture. Both cover another two years of active status and nothing else. Neither row includes the contractor bond, the workers compensation certificate, or an Industry Expert assessment from the Enforcement Division; those are separate obligations, and an LLC carries an employee or worker bond on top of the contractor bond. The classification row changes the license fee; it does not bundle the other requirements.
The delinquent pair: $695 and $1,070
Once the expiration date has passed, the table moves to the delinquent block, where the C-10 rows read $695 for a sole owner and $1,070 for a non-sole owner. Those two numbers are copied exactly as printed. This page will not say what makes up the difference between $470 and $695, because the table lists amounts rather than arithmetic. What can be said without guessing is that the classification still matters after the deadline: the electrical rows stay $20 above the ordinary delinquent rows. The delinquent page holds the ordinary late rows for comparison.
The extra sits on the row, not on a second line
A reader who expects $450 plus $20 has the shape wrong. The table has no ordinary renewal line and separate electrical surcharge line; it has one row that already includes the classification. Paying the C-10 sole owner renewal means paying $470, not $450 and then a second payment of $20. The distinction matters when you compare your notice with the table and see two figures that look $20 apart: that is one row against another, not one row plus something.
A license with several classifications
Licenses often carry more than one classification. The point this page can state comes from how the table is built: when C-10 is on the license, the C-10 row is the one that applies. You do not add a row per classification, and you do not stack the C-10 amount on top of another classification amount. The table has one renewal row for the license, with a C-10 version and an ordinary version. Whatever else the license carries, you are looking at a single renewal fee.
If the license is not C-10
Not every contractor license carries the electrical classification, and the $20 difference does not reach a license without it. If C-10 is not on the license, the ordinary rows apply: the sole-owner page covers a license held by one person at $450 active and $300 inactive, and the company page covers a partnership, corporation, LLC or joint venture at $700 active and $500 inactive. Both use the same source table and both stop where the table stops. Nothing about the electrical classification belongs on a license that does not carry it.
How to confirm the classification on the record
Three places show the classification and they should agree. The wall certificate prints the classifications the license holds. The renewal notice, mailed about 60 days before expiration, repeats them. And the public license lookup at https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx returns the record for a license number, including the expiration date, so you can confirm both the classification and the deadline from a source that is not this page. If the lookup and the certificate disagree, resolve that with CSLB before paying; the row follows the classification.
Why there is no total for a late C-10 renewal
This page has the delinquent C-10 rows and will not turn them into a grand total. The reason is the one that keeps every page here from doing arithmetic on a late renewal: the CSLB table contains a row whose parenthetical does not match its own label, so a calculation built on top of it would inherit the contradiction and present it as a confident number. Adding the $20 to a late figure, or projecting a total from a partial month, is the same mistake in a smaller package. Read the delinquent row, or call 800-321-2752.
Questions
Do I pay the ordinary fee and then the $20 separately?
No. The C-10 amount is a row of its own on the table, not a surcharge stacked on the ordinary row. An active timely C-10 renewal held by a sole owner is $470, not $450 plus a second $20 payment.
I hold C-10 and another classification. Which row?
The C-10 row, at $470 for a sole owner or $720 for a company when the renewal is active and timely. The table carries one renewal row for the license, so you do not add a row for each classification.
What is the $695 figure?
It is the delinquent C-10 row for a sole owner, copied from the table exactly as printed. The delinquent C-10 row for a non-sole owner is $1,070. Both apply only after the expiration date has passed.
Is there an inactive C-10 row I can use?
The table read for this page lists inactive rows for sole owners and non-sole owners without a separate C-10 column, so this page will not state an inactive C-10 amount. If the license is inactive rather than active, confirm the figure with CSLB at 800-321-2752 before paying.
Where do I check that C-10 is really on my license?
The wall certificate, the renewal notice and the CSLB license lookup should all show it. The lookup at https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx returns the record for a license number, including the expiration date, and it is the quickest of the three.
