Hired an Unlicensed Contractor? Here's What the Law Says in Every State

You hired a contractor. The work is incomplete, the quality is unacceptable, or they've disappeared entirely. And now you've found out they were never licensed to begin with.

Before you panic, understand this: in many states, being the victim of an unlicensed contractor actually puts the law firmly on your side. In California alone, homeowners can recover every dollar they paid — including for work that was completed and accepted. The unlicensed contractor, meanwhile, has virtually no legal recourse to collect what they say they're owed.

This guide explains exactly where you stand: what "unlicensed" actually means, what you can do about it, and how contractor licensing requirements break down across all 50 states.

What "Unlicensed" Actually Means

The word "unlicensed" covers more ground than most homeowners realize. A contractor might be working without proper credentials in any of these ways:

No license at all. The most obvious case — they never obtained a contractor's license.

Expired license. A license that was valid at one point but lapsed. In most states, working with an expired license carries the same legal consequences as having no license at all.

Wrong license type. A general contractor doing electrical work, or an electrical contractor performing plumbing. Each trade typically requires its own license. Crossing into unlicensed territory for a specific trade is a violation even if the contractor holds other valid licenses.

License in the wrong state. Contractor licenses are not transferable across state lines. A licensed contractor in Nevada is an unlicensed contractor in California.

License held by someone else. Some contractors use a "designated licensee" — someone who holds the license on paper but isn't actually on your job. This is a violation in most states and can invalidate the license entirely for purposes of your project.

Below the threshold. Some states only require licenses above a certain dollar amount. If a contractor performs work above that threshold without a license, they're operating illegally regardless of how small it seems.

Can You Sue an Unlicensed Contractor?

Yes, in most states you can sue an unlicensed contractor. The more useful question is what grounds you're suing on and what you're likely to recover.

Breach of contract is the most common claim. Even an oral agreement creates enforceable obligations, though written contracts are far easier to prove. If the contractor took a deposit and didn't complete the work, failed to meet quality standards, or abandoned the project, you have a breach of contract claim regardless of their license status.

Fraud or misrepresentation is available if the contractor claimed to be licensed when they weren't. This is a stronger claim than breach of contract because it opens the door to additional remedies — in some states, including punitive damages.

Negligence covers shoddy workmanship that caused damage to your property. You don't have to prove intentional wrongdoing, just that the contractor failed to perform at an acceptable standard.

What to document before you file:

The contract (written or a summary of verbal terms)
All payments made (checks, receipts, bank records, Zelle/Venmo records)
Photos of the work in progress and current condition
Any text messages, emails, or voicemails
Permit records showing what was pulled (or wasn't)
Any complaints or responses from the contractor

For claims under $10,000–$15,000 (depending on state), small claims court is faster and doesn't require an attorney. Larger claims go to civil court and may benefit from legal representation.

Can an Unlicensed Contractor Sue You for Payment?

This is where unlicensed contractors run into a wall — and where homeowners have significant leverage.

In California, Business and Professions Code §7031 is one of the most powerful contractor-protection statutes in the country. Under §7031(a), an unlicensed contractor is barred from bringing any legal action to collect compensation for work requiring a license. Under §7031(b), a homeowner can affirmatively sue to recover all compensation already paid to an unlicensed contractor — even if the work was completed, even if the homeowner knew about the license problem, and even if the quality of work was acceptable.

That last point is striking. California courts have called §7031 a "harsh" rule, but they enforce it consistently. The legislature's intent was to deter unlicensed contracting so thoroughly that there is no middle ground. If you paid $80,000 to an unlicensed contractor who built a beautiful kitchen, you can potentially recover the full $80,000. California courts have upheld this even when it produces results that seem unfair to the contractor.

In most other states, the rule is less extreme but still protective of homeowners. The general principle across the country is that courts will not help an unlicensed contractor collect money for work that required a license. What varies is:

Whether partial recovery is allowed (some states let contractors recover their actual costs, just not profit)
Whether the homeowner can affirmatively recover money already paid (most states don't go as far as California)
Whether the rule applies only to the specific unlicensed work or to the entire contract

The practical effect: If you are in a dispute with an unlicensed contractor who is threatening to sue you for an unpaid invoice, their threat has far less legal weight than they may let on. Consult a local attorney to understand exactly where your state stands, but the starting position is almost always more favorable to the homeowner than the contractor wants you to believe.

Can an Unlicensed Contractor Put a Lien on Your Property?

A mechanic's lien is a legal claim against your property that can complicate a sale or refinance if left unresolved. It's the contractor's most common pressure tactic.

In most states, the right to file a mechanic's lien is tied to licensure. A contractor who was not properly licensed at the time of the work generally cannot enforce a mechanic's lien. In California, this is explicit: courts have held that §7031 bars unlicensed contractors from enforcing mechanic's liens, not just from suing on the contract.

However — and this is important — an unlicensed contractor can still file a lien even without the legal right to enforce it. Filing a lien doesn't require a court's approval upfront. The filing creates a cloud on your title, and clearing it requires action on your part, whether that's filing a petition to release the lien or waiting for the contractor's claim to expire.

If an unlicensed contractor files a lien on your property:

Don't ignore it. It won't go away on its own in most states.
File a petition to release the lien in court. In most states, the contractor will have to prove their right to enforce it — which, if unlicensed, they can't.
Document the unlicensed status clearly before filing. A CSLB verification, state license board lookup, or permit record showing no licensed contractor of record is your evidence.

How to Actually Get Your Money Back

The path depends on how much you're owed and how much evidence you have.

1. File a complaint with the state contractor licensing board. Every state with a contractor licensing requirement has an enforcement body. Complaints are free to file, and a formal investigation puts pressure on the contractor and creates an official record. In some states, the board has a recovery fund that can compensate homeowners directly — California's Contractor State License Board, for example, maintains a fund specifically for this purpose.

2. Small claims court. For amounts up to the state's small claims limit (typically $7,500–$25,000 depending on the state), small claims is the fastest route. No attorney required. Bring your contract, payment records, photos, and evidence that the contractor was unlicensed. Judges in small claims courts see contractor fraud regularly and take it seriously.

3. Surety bond claim. Licensed contractors are often required to carry a surety bond — essentially insurance that protects the homeowner if the contractor causes damage or fails to complete the work. If the contractor had a bond (even if their license was otherwise deficient), the bond may cover your losses. Contact the bonding company directly.

4. Civil suit. For larger amounts or where fraud is involved, a civil suit may be warranted. An attorney can evaluate whether punitive damages, attorney's fees, or other remedies are available beyond your direct losses.

5. State attorney general or consumer protection office. Unlicensed contracting is often treated as a consumer protection violation, not just a civil matter. A complaint to the AG can trigger investigations that have more teeth than a small claims judgment.

What to Do Right Now

If you're currently in a dispute with an unlicensed contractor:

Stop all payments immediately. Do not pay any more until the situation is resolved.
Verify their license status through your state's contractor licensing board website.
Preserve all communications. Screenshot texts, save emails, document every conversation.
Do not let them return to the property without consulting an attorney first.
File a complaint with the licensing board. Even if you pursue other remedies, this creates a formal record.
Consult a local attorney before signing any settlement or release. Some contractors will pressure you into signing away your rights.

Contractor Licensing Requirements by State

Licensing requirements vary significantly across the country. Some states require a rigorous exam and years of documented experience before issuing any contractor license. Others require only registration — a lighter process that verifies identity and insurance but doesn't test competence. A handful of states leave licensing entirely to local jurisdictions.

Here's how all 50 states break down:

States That Require a State-Level Contractor License

These states require contractors to pass a licensing exam, prove experience, and maintain active credentials through the state before performing work above their threshold.

States That Require Registration (Not a Full License)

These states require contractors to register with a state agency — typically verifying insurance, identity, and sometimes a background check — but do not require passing a competency exam at the state level.

State	Registration Body	What It Requires
Colorado	Local jurisdictions + some state oversight	Roofing contractors must register statewide; general contractors mostly regulated locally

Wisconsin	Dept. of Safety and Professional Services	Dwelling Contractor registration required for residential; one- and two-family homes

States With No State-Level GC License (Local Rules Apply)

In these states, there is no statewide general contractor license requirement — but that doesn't mean anything goes. Local jurisdictions often fill the gap with their own licensing or permit requirements. And in all of these states, specialty trades (electricians, plumbers, HVAC technicians) are still licensed at the state level.

State	What to Know
Illinois	No state GC license; Chicago has its own contractor licensing; permits required city-by-city
Kansas	No state GC license; local jurisdictions set requirements; verify with your city or county
Missouri	No state license for general contractors; trades (electrical, plumbing) are state-licensed
New York	The state requires Home Improvement Contractor registration for work over $500, but NYC, Nassau, and Suffolk counties have separate — and stricter — licensing requirements
Texas	No state license for general contractors; electricians, plumbers, and HVAC technicians must hold state licenses; permit requirements enforced at city level
Vermont	No state GC license; local permits required; specialty trades have limited state oversight
Wyoming	No state GC license; local requirements vary; verify with your county

Verify Before You Hire

The easiest way to avoid every problem in this article is to verify a contractor's license status before signing anything. Every state licensing board maintains a public lookup tool where you can confirm a license is active, check for disciplinary history, and verify that the license covers the type of work you're hiring for.

Jaspector's contractor license requirements pages walk through what's required in each state — including the licensing body, threshold amounts, and what to check before you hire.

Once you've confirmed a contractor is licensed, protect yourself with a written contract before work begins. A contractor agreement should spell out scope, payment schedule, change order process, completion timeline, and what happens if either party defaults. Jaspector's contractor agreement templates are written for homeowners and available by state — so the language is appropriate for where you live and the work you're having done.

Licensing verification and a solid contract won't guarantee a smooth project. But they're the two things that give you real leverage if something goes wrong — and as you've seen in this guide, leverage is exactly what separates homeowners who get their money back from those who don't.
