# How do you verify a contractor's license in California?

**Short answer:** Search the Contractors State License Board public license lookup by license number rather than by business name. The record shows status, classifications, bonding, workers compensation and any disclosed discipline. Then confirm the classification covers your scope and the licensed entity matches the name on your contract. Verify general liability insurance separately, because the board does not report it.

## Start with what this is, and is not

This describes how license verification works in California and what the
record does and does not tell you. It is general information, not legal
advice, and no article can be. If money is already at stake, take the facts to
your own attorney. The checks below are still worth running yourself, because
they are free and they take minutes.

## The lookup itself takes about two minutes

The Contractors State License Board maintains a public license lookup on its
website, free and open to anyone. You can search by license number, by
business name, or by the name of an individual associated with a license. It
returns the record for every California contractor license, including licenses
that have expired, been suspended or been revoked.

Ask for the license number in writing before you search, and search by that
number. Business name searches are the weak point. Similar names return
several records, a dissolved entity can share a trade name with an active one,
and it is easy to end up reassured by a license that belongs to someone else.

If a contractor is reluctant to give you a number, the check is already
finished. State rules generally require the license number to appear on
contracts, bids and advertising, so a number that is hard to obtain is
unusual.

## Reading the record

The lookup returns more than a yes or no. Six fields matter.

- **Status.** Active is the only one you can work with. Inactive means the
  license is held but not usable for contracting. Expired means renewal
  lapsed. Suspended usually points to a bond or workers compensation problem,
  an unpaid judgment or a board order.
- **Classification.** The trades the license authorizes. Covered in the next
  section, because this is where most owners get caught.
- **Bonding.** Whether the required contractor bond is on file, the surety
  issuing it, and the effective dates. A bond is a narrow protection against
  certain violations. It is not a warranty on your project and it is not a
  source of repair funds for ordinary defects.
- **Workers compensation.** Either a policy with a carrier and dates, or a
  certified exemption stating the licensee has no employees. An exemption on a
  contractor who plainly runs crews deserves a direct question.
- **Personnel.** The qualifying individual who holds the trade qualification
  for the license, plus officers or partners of record. Useful when a company
  appears to have changed hands.
- **Disclosed discipline.** Citations, accusations, judgments and certain
  arbitration outcomes the board has disclosed. A clean record is reassuring
  but not conclusive, because the board publishes what it has processed and
  within its own retention windows.

## Classification has to match the scope

A license is not general permission to build. It authorizes specific
classifications, and using a contractor outside their classification puts the
entire arrangement on unstable ground.

The structure is simple enough. General engineering covers infrastructure and
heavy civil work. General building covers structures, and generally requires a
project involving at least two unrelated trades, which is why a general
building contractor is the right holder for a whole house or a full remodel
and the wrong holder for a job that is only one trade. The specialty
classifications each cover a single trade: electrical, plumbing, HVAC,
roofing, concrete, drywall, painting and so on.

Two failure patterns come up repeatedly. The first is a specialty contractor
taking on a scope that has drifted past their classification, most often a
concrete or framing outfit that ends up running an entire addition. The second
is a general building contractor hired for a single-trade project, such as a
re-pipe or a re-roof, where the classification does not fit the work.

Compare the classifications on the record against the trades listed in your
scope of work. If a trade in the scope is not authorized by the license,
either it belongs to a properly licensed subcontractor under contract to your
contractor, or your contract needs to change. Scopes that lean on one trade,
including much of what gets grouped as
[specialty services](/specialty-services), routinely arrive that way.

## The name on the license is the name on the contract

Licenses are issued to a legal entity: a sole owner, a partnership, a
corporation or an LLC. The entity on the record and the party signing your
contract must be identical, down to the suffix.

This sounds pedantic and it is the check that saves people. Common mismatches
include a contract written in a personal name while the license belongs to a
corporation, a contract written to a newly formed LLC while the license still
sits with the original entity, and a trade name that reads close enough to the
licensed name to pass a quick glance. If the signing party does not hold the
license, the license offers you nothing. The bond does not respond, and board
complaints have no proper respondent.

Check the entity type on the record, check the personnel list, and write the
contract to the exact licensed name.

## Insurance is a separate question the board does not answer

The license record covers the bond and workers compensation status. It says
nothing at all about general liability insurance, which is the coverage that
responds when a contractor damages your property or injures someone on it.

Ask for a certificate of insurance sent to you directly by the broker or
carrier, rather than a PDF forwarded by the contractor. Then read four things:
the carrier and its rating, the policy period against your construction dates,
the limits per occurrence and in the aggregate, and whether the aggregate
applies per project or is shared across every job the contractor has running
that year.

Additional insured status is the piece most owners get wrong. A certificate
that names you as certificate holder means you were sent a copy and nothing
more. Actual protection comes from an additional insured endorsement issued by
the carrier and attached to the policy. Ask for the endorsement itself. Ask
the same of any subcontractor whose work worries you.

## What hiring unlicensed actually exposes you to

The savings are real and the exposure is worse than most people expect.

**You lose every consumer remedy at once.** No bond to claim against, no board
complaint process, no board arbitration. California law is generally
understood to let an owner recover compensation paid to an unlicensed
contractor and to keep that contractor from suing to collect what is owed, but
the case law carries exceptions and the result turns on the facts. Both are
lawsuits rather than remedies, and they take time and legal fees to pursue.

**Injuries can become your problem.** Without workers compensation coverage
behind the crew, an injured worker on your property may look to you as the
employer. Homeowner policies frequently exclude that exposure.

**Permits move exposure to you.** Unlicensed contractors often ask the owner
to pull an owner-builder permit. Signing as owner-builder generally puts you
in the responsible party's position for the work, for code compliance and for
anyone working on the site, which is worth walking through with your own
attorney first.

## The pass to make before you sign

**Search the number, not the name.** Then confirm the number on the record
matches the number printed on the contract and the bid.

**Read the classifications against your scope line by line.** Anything not
covered needs a named, licensed subcontractor.

**Match the entity exactly.** Suffixes included. Correct the contract, not
your assumption.

**Get insurance documents from the broker.** Certificate plus additional
insured endorsement, with dates that cover your construction window.

**Recheck on the day you sign.** Status can change between the bid and the
contract, and it changes silently.

A verified license is a floor, not a recommendation. It confirms the
contractor met the state's minimum requirements and stayed in good standing.
It says nothing about whether they run a clean site, hold a schedule or finish
what they start. Those answers come from references, from completed work you
can walk, and from how specific they are willing to be in writing. The rest of
the questions worth asking a builder are collected under
[choosing a contractor](/insights/topics/choosing). Verification simply keeps
you from spending that effort on someone who was never eligible to do the job.

## Frequently asked questions

### What does it mean if a license shows as suspended?

Suspension means the license exists but cannot legally be used for contracting until the underlying issue clears. Common causes are a lapsed bond, a workers compensation policy that expired, an unpaid judgment, or an unresolved board order. A contractor working under a suspended license is in the same practical position as an unlicensed one, so treat it as a stop rather than a technicality to sort out later.

### Does a certificate of insurance mean I am covered by the policy?

No. A certificate is evidence that a policy existed on the day it was issued and that you were sent a copy. It grants no rights under the policy. Being protected requires an additional insured endorsement issued by the carrier and attached to the policy itself. Ask for the endorsement document, not just the certificate, and confirm the policy period covers your construction dates.

### Can I hire an unlicensed person for a very small repair?

California allows minor work below a statutory dollar threshold to be performed without a license, but the exemption is narrow and the threshold is low. It does not apply where a permit is required, and it does not cover splitting a larger job into small pieces. Confirm the current threshold before relying on it, and understand that the exemption removes your access to bond claims and board complaints.
