Quick Takeaways On CSLB’s Illegal Advertising Enforcement
The California Contractors State License Board has introduced a new complaint form to target illegal contractor advertising and strengthen enforcement against unlicensed operators. Under California law, contractors must hold a valid license for projects totaling $500 or more, and licensed contractors are required to display their CSLB license number on all advertisements, from business cards to websites and vehicles. Unlicensed contractors may only advertise if they clearly state they are not licensed and limit work to projects under $500. The new complaint process gives licensed contractors and the public an easy way to report violations, helping remove bad actors from the market and protect consumers while leveling the playing field for compliant professionals.

Contractors State License Board Releases New Complaint Form Aimed at Illegal Advertising
|
The California Contractors State License Board (“CSLB”) has released a new complaint form aimed at illegal contractor advertising.
Under California Business and Professions Code section 7048, a California contractors license is required when a contractor performs work on a project under one or more contracts with an aggregate contract price of $500 or more.
- Unlicensed contractors may advertise so long as their advertisement indicates that they are not a licensed contractor. Bus. & Prof. Code §7027.2;
- Licensed contractors may advertise so long as they include their California contractors license number on all advertisements, including print, television and radio advertisements, contracts, subcontracts, bids, business cards, webpages, and commercial vehicles. Bus. & Prof. Code §§7027, 7027.1, 7029.5, 7029.6, 7030.5; and
- Prime contractors and home improvement contractors must also include specified language in their contracts. Bus. & Prof. Code §7030.
Note: As one commentator has pointed out, the CSLB’s news release below is technically inaccurate, in that it implies that a contractor can advertise without a California contractors license so long as the work being performed has a value of “$500and under.” Actually, Business and Professions Code section 7048 says that a California contractors license is required if a contractor performs work with a value of “$500 or more.”
Yeah, I know, it’s a difference of a buck. Who knows, maybe the CSLB is in the holiday spirit and giving unlicensed contractors a $1 break.
Angry about Unlicensed Competition? There’s a Form for That
Licensed contractors must include their CSLB license number in all forms of advertising. Those without a license can advertise as long as the ad states that they are not a state-licensed contractor, and the combined total of a project’s labor and materials costs is $500 and under (Business and Professions Code section 7027.1).CSLB has a new way to report illegal advertising activity to help level the playing field for licensees. An Advertising Complaint form now is available on the CSLB website to report unlicensed operators who illegally list their services on the Internet or in publications, in defiance of state contracting law.
