What You Actually Need Before You Take Money
The phrase “licensed, bonded, and insured” gets said like it’s one credential. It’s not. It’s three completely separate systems, run by different agencies, with different rules, different renewal clocks, and different consequences if you skip one. I spent years around guys who had one piece nailed down and assumed the other two just came along with it. They don’t.
This one’s about the “licensed” part, and it’s actually two or three systems stacked on top of each other, not one. Bonding and insurance are their own separate thing, and don’t cover the gap if your licensing isn’t in order.
Short version: Most tradespeople need to clear two separate licensing layers, not one: a trade-specific license from your state or local licensing board (if your trade requires one, and the threshold for “requires one” varies a lot), and a general business license or permit from your city or county that has nothing to do with your trade at all. On top of that, a few trades carry federal certifications that function like licenses even though nobody calls them that (EPA refrigerant handling, EPA lead-safe renovation work). Skipping any layer because you’ve got the others covered is a common and expensive mistake.
The Three Systems Hiding Behind One Word
When someone says a contractor is “licensed,” they usually mean the trade license: the state board credential tied to electrical, plumbing, HVAC, general contracting, and similar regulated trades. That’s real, and it’s the one most people think about first. But it’s not the only license question that applies to your business.
Separately, most cities and counties require a general business license or business tax certificate just to operate within their jurisdiction, completely independent of whether your trade itself is regulated. A plumber with a spotless state license can still be out of compliance for never registering with the city. These aren’t redundant copies of the same requirement. They’re two different agencies asking two different questions: one is “are you qualified to do this specific work,” the other is “are you a registered business operating in our jurisdiction at all.”
Then there’s a third layer that only applies to specific work: federal environmental certifications. These aren’t issued by a licensing board and nobody calls them a “license,” but functionally they operate the same way; you legally cannot do certain work without one, and there are real penalties for skipping them. More on those below.
Treating any one of these as covering the others is the mistake. Being cleared on your trade license doesn’t clear you on the city registration. Being cleared on both doesn’t clear you on an EPA certification if your work touches lead paint or refrigerant. Each layer gets checked separately, usually by a different agency, and each one can shut down a job or trigger a fine independent of whether the other two are in order.
Trade-Specific Licensing: Why There’s No Single Answer
This is the part people want a clean national answer for, and it doesn’t exist. Whether your specific trade needs a state or local license, and at what point (some states set a dollar threshold below which minor work is exempt), varies by state and sometimes by county. Electrical and plumbing work are licensed in nearly every state because they intersect with life-safety code. General contracting, HVAC, and roofing are licensed in most states but not all. Handyman-type work (painting, small repairs, non-structural fixes) is where it gets genuinely inconsistent: some states exempt it below a set dollar amount, others require a license from dollar one.
California is a useful example of how these thresholds move. The state’s long-standing $500 handyman exemption, unchanged since 2005, was raised to $1,000 per project under Assembly Bill 2622, effective January 1, 2025, according to the California Contractors State License Board’s own bulletin. That threshold covers total labor and materials combined, including materials the customer supplies themselves, and it only applies to work that’s genuinely minor: nothing requiring a permit, and nothing structural. Splitting one larger job into multiple smaller invoices to duck under the threshold is explicitly treated as a violation on its own, not a workaround.
The reason I’m walking through one state’s specific number instead of giving you a table for all fifty: that table would be wrong within a year, because these thresholds actually move (California’s just did, for the first time in nearly two decades). Your state’s contractor licensing board is the only source that stays current. What’s worth taking from the California example is the pattern: there’s often a real dollar line, it’s not fixed forever, and the “just don’t invoice over the line” workaround doesn’t hold up.
Skipping a license you actually needed isn’t a paperwork slap on the wrist. California’s penalties for contracting without a required license run up to six months in jail and a $5,000 fine on a first offense, on top of a separate administrative fine, with a mandatory jail sentence on a second offense, per CSLB’s own consequences page. The part that surprises people more than the fine: in California, and in a number of other states, a customer isn’t legally required to pay an unlicensed contractor for the work, and the contractor can’t sue to collect. You can do the job correctly, on budget, on time, and still have zero legal path to getting paid if the license wasn’t in place first. That’s not a minor compliance detail, that’s the whole job for nothing. Getting the licensing right is what makes everything in the contracts and getting paid guide actually enforceable in the first place.
The General Business License Layer
Separate from any trade credential, most jurisdictions require some form of general business license or business tax registration just to legally operate, and this applies regardless of whether your specific trade is separately regulated. About 29 states require some form of state-level general business license, according to industry licensing guides, while others push that requirement down to the city or county level instead, or skip a blanket general license and rely on tax registration and industry-specific rules instead. There’s real state-by-state variation here too, which is exactly why checking your specific city and county clerk’s office matters more than assuming your trade license covers it.
If you’re operating under a name other than your own legal name (a common move once you’ve decided you’re building a real business and not just a side gig), most states also require a separate DBA (doing business as) or fictitious business name filing, on top of whatever business license you carry. This is its own filing, with its own fee, usually through the county clerk or secretary of state, and it’s commonly missed because people assume forming an LLC or getting a trade license automatically registers the name they’re operating under. It doesn’t. LLC formation, trade licensing, and DBA registration are three separate systems that don’t talk to each other.
Sales Tax and Seller’s Permits
If any part of what you do involves selling materials or products, not just billing for labor, you may also need a seller’s permit or sales tax license from your state, separate from every license above. This is the layer that gets overlooked most often by trades that think of themselves as service businesses. If you mark up materials on an invoice rather than passing them through at cost, or if you sell products directly (parts, supplies, retail add-ons), that can trigger a sales tax collection obligation depending on your state. Pure labor-only service states are the exception, not the rule; check your specific state’s rules on materials markup before assuming labor-only status protects you.
Federal Certifications That Function Like Licenses
A couple of certifications don’t come from a state licensing board at all, they’re federal, tied to environmental law, and they behave differently from each other in a way that trips people up.
If your work involves servicing, repairing, or disposing of equipment that could release refrigerants (HVAC and refrigeration work), you need EPA Section 608 technician certification. The useful detail here: this one doesn’t expire. Per the EPA’s own Section 608 certification page, once you pass the certification test, the credential is good indefinitely, no renewal required.
If your work involves renovation, repair, or painting in housing or facilities where children are routinely present that were built before 1978, EPA’s Renovation, Repair and Painting (RRP) rule requires firm certification, and this one works the opposite way: it expires. Firm certification is valid for five years, renewal applications need to go in at least 90 days before expiration, and the fee structure runs around $300 for standard renovation firm certification, per EPA’s RRP firm certification page. Miss the 90-day renewal window and it gets treated as a brand new application instead of a renewal, which can leave you uncertified while it processes. Two federal certifications, both administered by the same agency, one permanent and one on a five-year clock. Worth tracking separately rather than assuming they behave the same way.
Local Permits Are Their Own Layer, Too
Beyond licensing, a lot of trades run into permit requirements that are project-specific rather than business-wide: building permits, electrical permits, or zoning permits tied to a specific job site, pulled per project rather than once for the business. If you’re running the business itself out of your home, a separate home occupation permit may apply too, which is a zoning question about where the business is based, not a question about the trade work itself. These get confused with the general business license because they’re both handled by the same city office in a lot of jurisdictions, but they’re answering different questions: one is “can this business exist here,” the other is “is this specific job authorized.”
A Claim Worth Correcting: “My LLC Covers My Licensing”
You may have seen this assumption floating around, sometimes stated outright: form an LLC and your licensing requirements are handled, or at least reduced. They’re not related systems. Forming an LLC changes your business’s legal structure and liability exposure (the NAICS classification article and the business structure guide both cover that ground). It does nothing to your trade licensing status, your city business license, your DBA filing, or your EPA certifications. A well-formed LLC with zero licensing in place is exactly as exposed to unlicensed-contracting penalties as a sole proprietor would be. The two systems don’t check each other, which means neither one substitutes for the other.
How to Actually Check What You Need
Skip the forum threads and the outdated blog posts (including, eventually, this one; verify current thresholds before acting on anything time-sensitive here). Start with your state’s contractor or trade licensing board directly for the trade-specific question, then your city or county clerk’s office for the general business license and any DBA filing, and check EPA’s own certification pages directly if your work touches refrigerant or pre-1978 renovation. All three are separate lookups because they’re separate systems. If you’re setting up a registered address for any of this paperwork, that’s covered in the business address and registered agent guide, and once the licensing side is squared away, building business credit separate from your personal credit is usually the next practical step.
Frequently Asked Questions
Usually yes. A state trade license and a city or county general business license answer two different questions: whether you’re qualified to do the work, and whether you’re a registered business operating in that jurisdiction. About 29 states require some form of state-level general business license, and many more push the requirement to the local level, independent of your trade credential.
Some states set an exemption threshold for minor, non-structural work, but it’s not universal and the amount varies by state. California raised its threshold from $500 to $1,000 per project (labor and materials combined) starting January 1, 2025, the first change since 2005. Splitting one job into multiple smaller invoices to stay under a threshold is treated as a violation on its own in most states that have this rule.
Penalties typically stack: administrative fines from the licensing board, and in some states, criminal penalties including jail time on repeat offenses. California’s first-offense penalty runs up to six months in jail and a $5,000 fine plus a separate administrative fine. In several states, including California, an unlicensed contractor also has no legal right to sue for payment, meaning you can complete the work correctly and still have no path to collecting for it.
No. LLC formation and trade licensing are unrelated systems run by different agencies. Forming an LLC changes your business structure and liability exposure; it does nothing to your trade license, general business license, DBA filing, or any federal certification your work requires. A properly formed LLC operating without required licenses carries the same unlicensed-contracting exposure as a sole proprietor in the same position.
It depends which one. EPA Section 608 refrigerant handling certification does not expire once earned. EPA RRP (lead-safe renovation) firm certification does expire, on a five-year cycle, with renewal applications due at least 90 days before the expiration date. They’re both federal and both administered by the EPA, but they run on completely different clocks.
If you never mark up materials and never sell products directly, some states won’t require one. But if you mark up materials on invoices or sell parts, supplies, or products, that commonly triggers a sales tax collection obligation depending on your state, separate from your trade or business license. Check your specific state’s rule on materials markup rather than assuming labor-only status covers you.
