When you need a contractor license

The customer's list has six items. Five are plainly yours. The sixth is a dedicated circuit for the garage freezer, and you are in the truck working out whether you are allowed to price it at all.

That is three questions, not one. Does this state license contracting at all? Is this trade licensed on its own? Does this job need a permit? A job can pass one and fail the next two.

Question one: the general contractor license

A small-job exemption is a dollar cap with conditions welded to it, and the conditions do the work. Three states, from their own statutes — none of these numbers applies unless you are in that state.

Other states have no exemption at all, and some leave licensing to cities and counties, so the answer can change across a county line.

The cap counts the project, not the invoice. All three statutes close the splitting loophole in writing. California's does not apply where the work is only part of a larger or major operation, or where the job was split into contracts under $1,000 to evade the chapter. Arizona's reads the same way. Nevada's uses a different number from its own cap, and that is not a typo: it rules out work forming part of a larger project worth $500 or more, or for which contracts under $500 were awarded to evade the chapter. A Nevada job can therefore clear the $1,000 exemption and still fail the $500 test. In a $1,000-cap state, writing one $6,000 remodel as eight $750 invoices is the trap, not the workaround.

Question two: the trades that are licensed anyway

Electrical, plumbing and HVAC are licensed in most states regardless of the general answer. Pesticide application is regulated everywhere, at least for restricted-use products. Irrigation is licensed in only a few states, but where it is, it bites hard.

Texas breaks most people's intuition. It licenses neither general contractors nor handymen statewide, yet it licenses electrical and air-conditioning and refrigeration work through the Texas Department of Licensing and Regulation and plumbing through the Texas State Board of Plumbing Examiners — both statewide. A state with no license can still have a city with one.

Two more catch landscapers and maintenance crews:

• Pesticide and fertilizer application. Federal law requires certification to apply restricted-use pesticides, and the EPA says in as many words that "many state pesticide regulatory agencies require applicator certification to use all pesticides commercially, whether or not they are RUPs." Some states also certify fertilizer application on its own track — New Jersey's ProFACT certification is one. If you sell weed control, grub control or a fertilization program, assume you need a certified applicator until the state says otherwise. Which agency that is varies: often the department of agriculture, but New Jersey runs pesticides through its environmental agency and fertilizer through Rutgers.
• Irrigation. Where sprinkler work is licensed on its own, the issuing body is rarely the contractor board. Texas licenses landscape irrigators through the Texas Commission on Environmental Quality, and there you may not sell, design, install, alter, repair or service an irrigation system without that license. New Jersey has a dedicated Board of Landscape Irrigation Contractors. Backflow prevention is a separate certification again, sometimes from the state, sometimes from the local water utility, because it is a drinking-water issue.

Question three: the permit

A permit goes either to a licensed contractor or to the owner acting as owner-builder. A job that needs one is usually a job you cannot pull the permit for.

If the homeowner offers to sign as owner-builder, say out loud what that does first. California's board puts it bluntly: it makes them responsible for the whole project — supervising and paying the trades, and, if they use anyone who is not a licensed subcontractor, potentially counting as that person's employer, with the tax and workers' compensation obligations that carries. Other states are similar, but check your own building department's form. And be clear with yourself too: their signature does not make your own workmanship someone else's problem.

The referral trap

You do not have to turn the customer down. Take the five items that are yours, refer the sixth to a licensed electrician, keep the visit.

What does not work is treating subcontracting as a way around the license. California Business and Professions Code §7026 defines a contractor as someone who does the work "himself or herself or by or through others," and adds that "'contractor' includes subcontractor and specialty contractor." Arranging the work and marking it up is contracting.

That does not make subcontracting illegal. A licensed general contractor subs out specialty trades and marks them up. That is the normal shape of the business. The problem is narrower: taking on a scope your own license does not cover, or taking it on with no license at all. California adds a second layer, because §7059 limits what a specialty contractor may take on outside its classification. Whether a job is inside your classification is a question for your board.

Outside your lane, the clean version is a referral, with the customer paying the trade directly.

What being wrong costs

Two mechanisms, and the money one is usually worse. California's version is written down plainly, so it is the example.

Contracting without a license there is a misdemeanor. A first conviction carries a fine of up to $5,000, up to six months in county jail, or both (B&P §7028).

Separately, §7031 bars an unlicensed contractor from bringing any action to collect payment for work "where a license is required by this chapter," and lets the customer sue to recover all compensation already paid. You can finish the job, be paid in full, and still owe it all back. Two things bound it. It only bites where a license was required in the first place, so work genuinely inside the §7048 exemption is outside its reach. And a California appellate court held in 2020 that the customer's claw-back claim carries a one-year limitations period running from completion, with no discovery rule to stretch it (Eisenberg Village v. Suffolk Construction). §7031(e) also leaves a narrow substantial-compliance route for someone who held a license before the work, acted in good faith to keep it, and did not know it had lapsed. Narrow is the operative word.

Lien rights go the same way. Arizona writes it into the lien statute itself: A.R.S. §33-981(C) says a person required to be licensed who does not hold a valid license "shall not have the lien rights provided for in this section." California reaches a similar place through §7031 case law rather than through its lien statute — Civil Code §8400, which lists who has a lien, carries no licensing condition on its face. Every other state writes its own version, and they do not converge, so do not carry either of these across a state line.

One more call: your general liability agent, in writing. There is no industry-wide "unlicensed work" exclusion, so anyone telling you flatly that you are uncovered is overstating it. On an unendorsed standard form, the classification codes and description of operations you gave the carrier are how the policy is priced, not a list of what is covered. What restricts coverage is an endorsement — a classification limitation or a designated work exclusion — tying coverage to the operations named on your declarations. Ask whether yours carries one, now rather than at claim time.

Where the real answer lives

Three calls settle almost every version of this: your state licensing board, the trade board or agency for your specific work, and the building department where the job is. A state-by-state summary site is not one of them — California's cap doubled in January 2025, and a summary is only as current as the day someone last edited it.

Quoting only the work you can take

Your line only helps if it survives onto the paperwork. Keep your standard exclusions in DoneQuote as reusable lines — "dedicated circuit by a licensed electrician, arranged by the homeowner" is a sentence you write once — so the boundary you worked out in the truck is the one the customer signs.
