The licensing test for a general contractor's agency

Early March is when many general contractors hire the marketing help they put off all winter. Spring starts are being permitted, and last fall’s bids are turning into contracts.

Before that agency writes a single ad, ask it about your license. In our experience it is the fastest way to separate an agency that has worked with contractors from one that has worked with “home services” in general, and when the agency gets it wrong, the notice from the licensing board arrives on your desk, not theirs.

Ask what your license class lets you advertise

General contracting is licensed in classes, and the class sets limits on the words an ad can use.

In California, the Contractors State License Board’s advertising guidelines say A General Engineering and B General Building licensees can advertise as general contractors, and that nobody may advertise work outside their own classification. The B license itself only allows a prime contract that involves at least two unrelated trades other than framing or carpentry. The B-2 Residential Remodeling class needs three unrelated trades on a single contract in an existing wood frame home. An agency that writes “full-service general contractor” for a B-2 firm has written an ad the license does not support.

Florida splits the work three ways. 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.

A competent agency asks for your class in the first meeting and checks whether it backs the work you want to be known for.

Ask where the license number will go

Agencies slip here most often, because a number in the footer feels like enough. In the strictest states it is not.

• California. CSLB wants the number in all forms of advertising, which its guidance says includes websites, directories, proposals and vehicle lettering. A first offense carries a civil penalty of $100 to $1,000. Commercial vehicles need the business name and number in at least 72-point type, or letters three-quarters of an inch high.
• Florida. Section 489.119 of the state’s statutes puts the number in each offer of services, business proposal, bid, contract or advertisement, “regardless of medium”. The board starts with a notice of noncompliance and can fine a contractor who has not fixed it within 30 days.
• Arizona. Since September 29, 2021, broadcast, internet and billboard ads may leave off the Registrar of Contractors number if they give a web address whose home page shows the name and number somewhere other than the footer, according to attorney Jason Clark of Lang & Klain, writing in AZ Big Media. Print ads, bids, estimates and letterhead still need it.
• Texas. The Texas Sunset Advisory Commission records that the state’s Residential Construction Commission was abolished when House Bill 2295 failed to pass in 2009, so for Texas clients we start with the city’s requirements.

Ask the agency to show you where the number will sit in a search ad, a Facebook post and your proposal template. If the answer is “in the footer”, keep interviewing.

Ask what they will refuse to write

Good contractor marketers keep a short list of things they will not write, and can explain each.

• “Licensed, bonded and insured.” CSLB’s guidelines say California law prevents contractors from mentioning bonding in advertising, because homeowners may read it as more protection than it is.
• Lead-safe renovation without the certificate. The EPA says firms cannot advertise or perform renovation covered by its lead paint rule in homes built before 1978 without firm certification.
• “Sign today” pressure after an in-home visit. The FTC’s Cooling-Off Rule gives buyers until midnight of the third business day to cancel most sales made at home, and Saturday counts as one of those days. California gives three business days, or five when the buyer is 65 or older. Urgency offers copied from emergency trades collide with both.

What the first ninety days should look like

For a general contractor, a sound plan starts with being chosen rather than being found. Even a referred homeowner checks you before agreeing to a site visit. BrightLocal’s 2026 Local Consumer Review Survey, published last month, found that 54% of consumers go to a business’s website after reading positive reviews, and that 47% will not use a business with fewer than 20 reviews. Houzz’s 2026 kitchen trends study found general contractors were the professionals hired most for kitchen renovations, at 48%, so that homeowner is usually comparing you with other general contractors.

A reasonable sequence:

• Weeks one to three. Project pages for the work you want more of, your license number everywhere your state requires it, proof of insurance, and review requests to last year’s clients.
• Weeks four to six. A pipeline that follows each inquiry through site visit, bid and signed contract, with its source recorded.
• Weeks seven to ten. Your Business Profile and service areas (Google allows up to 20, and will not accept a virtual office unless it is staffed during business hours), the Local Services Ads application, and search campaigns aimed at large projects.
• Weeks eleven to thirteen. Follow-up on every open bid and the first report tying signed contracts to their sources.

Screening for the General contractor category in Local Services Ads includes background checks on the business and on its owner plus proof of liability insurance, and Google says it averages three to four weeks. An agency promising the Google Verified badge by next Friday has not been through it.

What a good monthly report shows

Search clicks are cheap for contractors and leads are not. LocaliQ’s 2025 home services benchmarks put the median click in Construction & Contractors (General) at $5.31, the lowest of its 16 categories, yet only 2.61% of clicks became leads, which left the median lead at $165.67. A report that celebrates clicks is measuring the cheap part. Ask instead for:

• Inquiries by source and project type, with small repair requests counted apart from real projects.
• Site visits held, and bids sent with their total value.
• Contracts signed, traced to the source of the first contact, even when that contact came last fall.
• Reviews added in the month. BrightLocal found 13% of consumers have spent more than $5,000 after reading reviews.

What to do this month

• Write down your license class and number, search for your own company, and list every place the number is missing: ads, profile, site, trucks and proposal templates.
• Ask each agency you are talking to which license classes it has worked with and what it would refuse to write for you.
• Request a sample monthly report and look for signed contracts by source rather than clicks.
• Gather insurance certificates and license details now if you want Local Services Ads running before spring starts.
• Send a review request to every client whose project finished in the past year.

An agency should know your license before it knows your keywords, and the interview is the cheapest place to find out whether it does. Our page for residential general contractors sets out how we plan that work, and our website builds show where the license, the projects and the proof belong.
