Trades by state coverage

How we rank licensing requirements

Our rankings are computed directly from the licensing-board record set we maintain — not editorially curated and not influenced by advertisers. Each ranking surfaces a clear, reproducible metric (for example, count of trades requiring a state-level license, total bond + insurance burden). The underlying numbers are visible on the associated state and trade record pages so you can verify each computation against the upstream board.

The "most regulated trades" ranking counts the number of states that require a state-level license for each trade in our dataset. Trades like electrical and plumbing routinely top this ranking; trades like painting and drywall sit near the bottom. The "least regulated states" ranking counts the number of trades a contractor can perform in a given state without a state-level license. Texas, Pennsylvania, and Massachusetts typically rank near the top of this list because they delegate licensing to municipalities or specific trades.

Rankings are a useful starting point, not a quality judgment. A state being "less regulated" does not mean it is "safer" or "more contractor-friendly" — it simply means the state has fewer statewide licensing requirements. Local cities and counties may impose additional registration, bonding, or permitting rules even where the state does not. We surface the raw counts and link to the official board so you can make your own assessment.

If you believe a ranking is miscomputed or that a record is misclassified, please contact us with the specific record ID and the expected correction. We investigate corrections at the next data refresh.

Why state-by-state licensing matters

Contractor licensing exists primarily to protect the consumer. When a state requires a license, it typically also requires bonding and insurance — which gives homeowners a path to recovery if work goes wrong. A licensed contractor has skin in the game: they can lose their license, their bond can be drawn against, and the state board can investigate complaints. An unlicensed contractor in the same jurisdiction has none of those constraints, and disputes typically have to be resolved through small-claims court or civil litigation with no regulator oversight.

States vary dramatically in how strictly they enforce these rules. In Florida, working without a required license is a third-degree felony — repeat offenders face thousands in fines and prison time. In Pennsylvania, by contrast, the state requires registration but does not test contractor competency, leaving most quality enforcement to local municipalities and civil courts. The PlainHireCheck rankings surface these differences side by side so you can quickly understand the regulatory environment in any state without having to read each licensing board's website.

What the rankings do not capture

Rankings cannot tell you everything you need to know before hiring a contractor. They surface the structural rules — does this state require a license, what bond is mandated, how many trades are covered — but they do not capture the individual contractor's track record. For that, every trade and state profile on this site links to the official board's verification tool. We strongly recommend using the board's lookup before signing any contract, because licensing status can change between data refreshes.

Rankings also do not capture local rules. Many cities and counties layer additional registration, bonding, or permitting requirements on top of state rules. A contractor licensed at the state level may still need a city business license to work inside the city limits, and that local rule may impose its own bond or insurance minimum. When in doubt, call both the state board and your local city or county licensing office before hiring.

Bond and insurance layer

The headline question — does this trade require a license in this state — is just the first layer. The second layer is the bond requirement, which determines how much money a homeowner can recover if a contractor disappears or refuses to fix defective work. Bond minimums vary from a few thousand dollars up to fifty thousand dollars or more for general contractors in states like California and Florida. A higher bond does not necessarily make a contractor more skilled, but it does mean the consumer has a more substantial financial recourse when something goes wrong.

The third layer is insurance. Most licensed-trade requirements include general-liability minimums in the seven-figure range plus workers' compensation if the contractor employs anyone. Workers' compensation is critical for homeowners — if an uninsured worker is injured on your property, you may be financially responsible for the medical bills and lost wages. Always confirm an active workers' compensation policy alongside the general-liability policy, and ask for the certificate of insurance with your name listed as the certificate holder before work begins. The fourth layer is continuing education; some states require renewal-cycle hours that keep contractors current on building-code changes.

Using rankings before hiring

Start with the state where the work will happen. Open the ranking for that state and read the bond, insurance, and exam requirements. If the state requires a license for your trade, the contractor must be able to provide a valid license number you can look up on the state board's website. If the state does not require a license, you should still ask the contractor for proof of general-liability insurance and workers' compensation — those protections matter regardless of whether the state board mandates them. Look up the trade in our most-regulated-trades ranking. A trade that is licensed in most states is usually licensed for a reason — electrical and plumbing failures cause house fires and floods. Cross-reference the contractor's license number against the state board's complaint database before signing any contract.
