Most trades carry one license and one rule about where its number goes. General contracting comes in classes, and the class decides what an ad is allowed to offer. We read every ad against yours before it runs.
California. A B General Building contractor may not take a prime contract unless the job requires at least two unrelated building trades other than framing or carpentry. The B-2 Residential Remodeling class needs at least three unrelated trades on a single contract, in an existing residential wood frame structure. CSLB’s advertising guidelines say A and B licensees can advertise as general contractors, that nobody may advertise work outside their own classification, and that no ad may mention being bonded. Small jobs under $1,000 can go without a license only when they need no permit and the business has no employees, a line that moved up from $500 on January 1, 2025.
Florida. A certified general contractor is unlimited as to the type of work. A building contractor is limited to buildings of up to three stories, or to remodeling of any size that leaves the structural members alone. A residential contractor covers one-, two- and three-family homes of no more than two habitable stories. Each class should advertise only the work it covers. The exemption for minor jobs under $2,500 is lost by anyone who advertises as a contractor, and it never covers a job split into smaller contracts to stay under the line.
Arizona. Arizona’s chapter of the Associated General Contractors says work valued at $1,000 or more needs a license from the Registrar of Contractors. Since September 29, 2021, a broadcast, internet or billboard ad may leave the ROC number off if it gives a web address whose home page shows the name and number somewhere other than the footer, as attorney Jason Clark explained in AZ Big Media. Bids, estimates, print ads and letterhead still carry it.
Texas. The Texas Residential Construction Commission was abolished when House Bill 2295 failed to pass in the 2009 session, according to the state’s Sunset Advisory Commission. In Texas we start with the city’s own rules before the first ad runs.
Older houses, in every state. Under the EPA’s lead renovation rule, a firm without certification may neither advertise nor carry out covered renovation work in housing built before 1978. Additions and whole-house remodels open walls in older neighborhoods all the time, so that certificate belongs on the site beside the license number.
A notice from a licensing board costs more than any campaign saves, which is why this check happens before the first ad, not after the first complaint.
