Check the CSLB Record Before You Commit
Use California’s official License Check before signing, paying a deposit or trusting a number shown in an advertisement. The legal business name, status, classification, bond and workers’ compensation information should all fit the proposed project.
This guide also explains search-name problems, inactive and suspended records, the $1,000 licensing rule, 2026 contract changes, HIS registration, application fees, cancellation rights, lien protection and public-works registration.
California Contractor License Search: Fast Answer
Use the free CSLB License Check to search by contractor license number, business name, personnel name, Home Improvement Salesperson registration number or HIS name.
Open the full record and verify active status, legal identity, classifications, bond, workers’ compensation and public complaint disclosures. A matching name by itself does not prove that the contractor may legally perform your project.
How to Use the Official CSLB License Check
California license numbers are numeric and contain no letters. Search the number first when available, then use business, personnel or HIS searches when identity remains unclear.
Enter the numeric license number
Do not add letters, classification codes or extra wording. Recheck every digit before concluding that no record exists.
Search the legal business name
Use the name printed on the estimate or contract. If an exact search fails, try the most distinctive portion of the name and remove unnecessary punctuation or introductory words.
Search the qualifying or business person
Personnel search can identify licenses associated with an owner, officer, partner, responsible managing officer or responsible managing employee.
Search the salesperson separately
When someone sells or negotiates home improvement work, verify their HIS registration as well as the contractor license behind the offer.
Open the complete license detail
Do not stop at a search-result row. Review status, classifications, personnel, bond, workers’ compensation and disclosed enforcement information.
Save and recheck the live record
Keep a dated screenshot with the contract and verify the record again before work begins or a large payment is released.
CSLB Business and Personnel Name Search Troubleshooting
Name searches often fail because an advertisement, DBA, corporation and qualifying person use different wording. Work from the project documents rather than guessing.
Business-name search tips
- Start with the exact legal name shown on the contract.
- Try a shorter distinctive portion when the full name fails.
- Remove punctuation and common introductory words.
- Search the owner’s name when a sole proprietor uses a DBA.
- Compare every returned entity instead of choosing the closest-looking name.
Personnel-name search tips
- Try the last name when the complete name returns nothing.
- Check spelling against identification, contracts and CSLB paperwork.
- Review every associated license and business entity.
- Confirm the person’s current role rather than relying on an old association.
- Do not assume the salesperson is the license qualifier.
How to Interpret a California Contractor License Result
A license record should be compared with the actual bid, contract, invoice, advertisement, permit application and requested payment recipient.
| Record field | Plain-English meaning | Action before hiring |
|---|---|---|
| Active | The license is currently usable, subject to its classifications and any listed restrictions. | Continue checking identity, scope, bond, workers’ comp and disclosures. |
| Inactive | The license remains on record but cannot be used to contract for work. | Do not sign or allow work until CSLB shows an active license. |
| Expired | The renewal period ended without an acceptable current renewal. | Wait for renewal and verify the updated public record. |
| Suspended | A bond, insurance, qualifier, judgment or disciplinary issue may prevent legal contracting. | Open every suspension detail and do not proceed until cleared. |
| Canceled or revoked | The credential is no longer available for ordinary contracting. | Do not treat an old license card or number as current authority. |
| Business name | Identifies the entity licensed by CSLB. | Match it to the contract, invoice, permit and payment recipient. |
| Classification | Defines the construction work the business may contract for. | Verify that the precise class covers the proposed scope. |
| Bond and workers’ compensation | Shows CSLB filings associated with the license. | Check effective dates and inconsistencies before paying. |
| Complaint or legal-action disclosure | CSLB discloses qualifying public enforcement information, not every complaint ever received. | Read the underlying dates and details; a referral for legal action is not itself a final finding. |
When a screenshot is not enough
For litigation, formal due diligence or historical status, CSLB offers certified license histories and certificates of non-license. A verified certificate can document business information, classifications, personnel, status, bond information and enforcement history for the requested period.

Complete this after opening the live official record. It does not replace CSLB, insurance verification, permits or legal advice.
When a California Contractor License Is Required
A contractor license is generally required when the combined project value reaches $1,000, the work requires a building permit, or employees or additional workers are used.
$1,000 total-cost trigger
Count labor, materials and other project costs together. A larger job cannot be divided into smaller agreements to avoid licensing.
Building-permit trigger
A lower-priced project can still require a licensed contractor when a permit is needed.
Employee or worker trigger
An unlicensed individual cannot rely on the minor-work exemption when employees or additional workers are used.
Conditions for the narrow exemption
- The complete job stays below $1,000.
- No building permit is required.
- No employees or additional workers are used.
- The job is not part of a larger project divided into smaller pieces.
- The person does not represent themselves as a licensed contractor.
- Advertising by an unlicensed person clearly states that the person is not licensed.
Tool 2: California License Trigger Helper

California CSLB License Classifications
The classification must match the work being sold. Verify the precise class instead of assuming that any general contractor can perform every specialty.
| Classification | Typical scope | What to verify |
|---|---|---|
| A — General Engineering | Fixed works, grading, utilities, roads and engineering construction. | The project is engineering work rather than ordinary building construction. |
| B — General Building | Structures involving at least two unrelated trades or crafts. | The project genuinely meets general-building scope or the contractor holds the required specialty. |
| B-2 — Residential Remodeling | Specified nonstructural remodeling of existing residential wood-frame structures involving multiple trades. | The work remains within B-2 limitations and does not include prohibited structural scope. |
| C — Specialty | A defined trade such as electrical, HVAC, plumbing, roofing, solar, landscaping or painting. | The exact C classification matches the principal work in the contract. |
| C-61 / D — Limited Specialty | A narrow field or operation not covered by a standard specialty class. | The specific D subcategory and endorsed description cover the work. |
CSLB Bond, Workers’ Compensation and LLC Checks
The contractor bond, qualifying-individual bond, workers’ compensation filing and LLC insurance requirements are different protections. One should not be used as proof of another.
| Protection | Current requirement | What users should check |
|---|---|---|
| Contractor bond | $25,000 for an active contractor license. | Exact business name, license number, effective date and cancellation information. |
| Bond of Qualifying Individual | $25,000 when required, including an RME or certain RMOs with less than 10% ownership. | Qualifier name, ownership exemption and separate filing. |
| Workers’ compensation | Required when employees are used and in other situations where exemption is unavailable. | Policy or exemption status against the people actually working on site. |
| LLC employee/worker bond | $100,000 in addition to the contractor bond for applicable LLC licensing activity. | Separate LLC bond filing and active-license status. |
| LLC liability insurance | At least $1 million for five or fewer personnel of record, increasing by $100,000 for each additional person up to $5 million. | Policy amount, insurer and personnel count. |
| General liability for non-LLCs | Not universally required by CSLB for every non-LLC contractor. | Request a certificate and verify current coverage directly with the insurer. |
Verify a Home Improvement Salesperson Registration
A person who solicits, sells, negotiates or executes home improvement contracts for a licensed contractor generally must register as an HIS, regardless of the contract amount, unless a listed exception applies.
What to check
- The salesperson is at least 18 and currently registered.
- The name matches the person who contacted or met with you.
- The licensed contractor has properly notified CSLB of the employment relationship.
- The contractor’s license is current, active and in good standing.
- Sales promises appear in the final written contract.
Can an HIS work for more than one contractor?
Yes. A properly registered HIS may work for multiple contractors. The licensed contractor must notify CSLB before employing the salesperson and must report employment cessation within 90 days.
California Contractor Changes Effective in 2026
CSLB’s 2026 bulletin highlights new home improvement contract, subcontractor disclosure, workers’ compensation and enforcement rules.
Email cancellation information
Home improvement contracts must include the contractor’s email address and allow buyers to cancel by email when the cancellation right applies. Contracts must also include a telephone number that helps the buyer locate and complete the Notice of Cancellation.
Subcontractor information on request
When subcontractors are used on a home improvement project, the prime contractor must provide requested names, contact information, license numbers and classifications.
Workers’ compensation enforcement
Penalties increased for workers’ compensation violations, and CSLB must develop a stronger process for verifying exemption eligibility.
Higher unlicensed-activity penalties
Beginning July 1, 2026, minimum civil penalties for specified violations increase, with fines for unlicensed activity starting at $1,500.
How to Apply for a California Contractor License
Most applicants use the examination route. The business entity and qualifying individual must be identified correctly before the experience, examination, fingerprint and issuance stages can be completed.
Select the business entity and one classification
The original application requests one classification. The legal business name must be compatible with the entity and must not mislead consumers about the licensed classification.
Confirm the qualifier’s experience
The qualifying individual generally must be at least 18 and document four full years of journey-level or higher experience within the previous 10 years.
Claim education credit carefully
CSLB may grant up to three years of credit for qualifying education, apprenticeship or training, but at least one year of practical experience is generally still required.
Submit the $450 original application fee
The fee covers one classification and is non-refundable after filing. Examination fees are paid separately to CSLB’s approved testing vendor when examinations are scheduled.
Correct returned applications within 90 days
If CSLB returns the application as incomplete, provide the requested corrections within 90 days of the return date or the application can become abandoned.
Complete fingerprints after the application posts
CSLB sends fingerprint instructions after accepting the application as complete. Out-of-state hard-card processing can take longer than California Live Scan.
Pass the required examinations
The qualifier generally completes Law and Business plus the applicable trade examination unless CSLB approves a waiver.
Complete license issuance
Submit the initial license fee, required bond, workers’ compensation documentation or allowed exemption, asbestos open-book examination and any other requested issuance item.
Current original-license fees
| Fee | Amount | When paid |
|---|---|---|
| Original application — one classification | $450 | Submitted with the original application. |
| Initial license — sole owner | $200 | After qualification and examinations. |
| Initial license — non-sole owner | $350 | After qualification and examinations. |
| Total CSLB application and initial fee — sole owner | $650 | Excludes examination-vendor, fingerprint and bond costs. |
| Total CSLB application and initial fee — non-sole owner | $800 | Excludes examination-vendor, fingerprint, bond and entity-specific costs. |
California Contractor License Renewal Rules and Fees
Active licenses renew every two years. Inactive licenses renew every four years and cannot be used to contract while inactive.
| Renewal type | Sole owner | Non-sole owner |
|---|---|---|
| Timely active | $450 | $700 |
| Timely inactive | $300 | $500 |
| Delinquent active | $675 | $1,050 |
| Delinquent inactive | $450 | $750 |
Renewal details that cause mistakes
- C-10 license renewals include an additional $20 electrician-certification enforcement fee.
- Online renewal is generally available only to entities with one qualifier.
- Licenses with multiple qualifiers must mail or hand-deliver the form and payment.
- An acceptable completed renewal received within 90 days after expiration may qualify for retroactive reinstatement.
- A change in ownership or business entity can require a new license rather than renewal.
- A delinquent license can generally be renewed for up to five years when ownership remains unchanged.
- Verify that CSLB’s public record updates before contracting again.
California Home Improvement Contracts, Deposits and Cancellation
Covered home improvement work over $500 in combined labor and materials requires a written contract. Read it before signing and do not leave blank spaces.
What the written contract should contain
| Contract item | What to verify |
|---|---|
| Contractor identity | Legal business name, address, license number, telephone and email. |
| Scope and materials | Detailed work, brands, models, grades, quantities, exclusions and cleanup. |
| Price and dates | Total price, approximate start, completion and payment milestones. |
| Down payment | $1,000 or 10% of the contract price, whichever is less, unless a verified statutory exception applies. |
| Progress payments | Each payment is tied to work performed or materials delivered and does not run ahead of value. |
| Cancellation notice | Required form, contractor telephone, email and cancellation instructions. |
| Change orders | Written scope, price and schedule changes approved before extra work starts. |
Three-day and five-day cancellation rights
A qualifying buyer generally receives three business days to cancel, or five business days when the buyer is age 65 or older. Written notice is generally sufficient, and the seller must return money paid within the applicable statutory process.
Payment and hiring safeguards
- Obtain at least three comparable written bids.
- Match the CSLB name to the contract and payment recipient.
- Do not pay cash without a detailed receipt.
- Do not let progress payments exceed completed work and delivered materials.
- Confirm who obtains permits and schedules inspections.
- Request subcontractor information before significant payments.
- Keep contracts, notices, photos, invoices and communications together.
Tool 3: California Deposit Limit Checker
This calculates the ordinary maximum down payment of $1,000 or 10% of the contract price, whichever is less. Limited statutory exceptions can apply.
California Mechanics Lien Protection
Subcontractors, laborers and suppliers can potentially record a mechanics lien when they are not paid, even when the homeowner already paid the prime contractor.
How to use Preliminary Notices
A Preliminary Notice is not itself a lien. It identifies a subcontractor or supplier that may later claim lien rights if unpaid. Keep every notice and compare it with the contractor’s payment requests.
Use joint checks
When paying for significant subcontractor work or materials, a joint check payable to the contractor and the supplier or subcontractor can help ensure both parties endorse and receive the payment.
Use the correct lien releases
Before payment
Request the appropriate signed conditional waiver and release from every potential lien claimant connected with that payment.
After payment clears
Request an unconditional waiver and release signed by the actual claimant for the amount paid.
California Public Works Contractor Registration Check
Contractors and subcontractors bidding or working on covered California public works projects may need active Department of Industrial Relations registration in addition to the appropriate CSLB license.
Verify DIR registration
Search the active Public Works Contractor Registration database. DIR recommends searching by the 10-digit registration number or a distinctive portion of the legal name.
Check debarment
Review the state debarment list before accepting a bid, awarding work or approving a subcontractor on a public works project.
Current public-works registration costs
DIR currently lists registration options of $400 for one fiscal year, $800 for two fiscal years or $1,200 for three fiscal years. Registration runs on a July 1 through June 30 fiscal-year cycle.
- Verify active DIR registration before bidding or working.
- Confirm workers’ compensation and CSLB status where applicable.
- Use only registered subcontractors when registration is required.
- Check prevailing-wage, apprenticeship and certified-payroll duties.
- Review the debarment list rather than relying only on CSLB License Check.
File a CSLB Complaint or Report Unlicensed Activity
CSLB accepts complaints involving licensed and unlicensed contractors. The regulatory process is separate from insurance claims, mechanics lien disputes, small claims and private lawsuits.
Build a useful evidence package
| Evidence category | What to preserve |
|---|---|
| CSLB records | Dated license result, business name, classification, HIS record and advertisements. |
| Contract | Signed agreement, cancellation notice, change orders, warranty and subcontractor information. |
| Payments | Deposits, invoices, receipts, checks, bank records and requested payment names. |
| Work condition | Dated photographs, videos, plans, permits, inspections and repair estimates. |
| Communication | Emails, texts, letters and written requests for completion or correction. |
| Timeline | A short date-by-date summary of promises, work, payments and unresolved issues. |
Complaint disclosure is not every complaint
CSLB can disclose qualifying investigated matters and legal actions. A matter referred for legal action does not automatically prove that a violation occurred; read the disposition and dates carefully.
Licensed versus unlicensed activity
Licensed-contractor problem
Use the construction complaint route for defective, abandoned, misrepresented, overpaid or out-of-class work involving a licensed business.
Unlicensed activity
Report use of another company’s number, work above the lawful exemption, permit work, worker use or advertising that violates unlicensed-contractor rules.
CSLB Phone, Application Status and Processing Times

California Contractor License Search FAQs
Where can I search a California contractor license for free?
Use the official CSLB License Check page. It supports searches by contractor license number, business name, personnel name, Home Improvement Salesperson registration number and HIS name.
How do I find a contractor when the business name search fails?
Try the exact legal name first, then use a shorter distinctive portion, remove unnecessary punctuation and search the owner or qualifying person where appropriate. Compare every possible match with the contract and payment name.
When is a California contractor license required?
A license is generally required when the complete project value reaches $1,000, a building permit is required, or employees or additional workers are used. A larger project cannot be divided into smaller contracts to avoid licensing.
Can an inactive or expired California contractor license be used?
No. An inactive, expired, suspended, canceled or revoked license should not be treated as authority to contract. Wait until CSLB shows the correct active status.
What is the California contractor bond amount?
The standard contractor bond is $25,000. A separate $25,000 bond of qualifying individual, a $100,000 LLC employee or worker bond, or a disciplinary bond may also be required in applicable situations.
Is a written contract required and how much can the deposit be?
Covered home improvement work over $500 requires a written contract. The ordinary maximum down payment is $1,000 or 10 percent of the contract price, whichever is less, subject to limited statutory exceptions.
How long do I have to cancel a California home improvement contract?
A qualifying buyer generally has three business days, or five business days when the buyer is age 65 or older. Contracts negotiated at the contractor’s place of business and certain emergency service-and-repair contracts have different rules.
How much experience and money are needed to apply?
The qualifier generally needs four years of journey-level or higher experience within the previous 10 years. The original one-classification application fee is $450, followed by an initial fee of $200 for a sole owner or $350 for a non-sole-owner entity.
How often must a California contractor license be renewed?
An active license renews every two years. An inactive license renews every four years and cannot be used for contracting while inactive.
How do I file a complaint against a California contractor?
Use CSLB’s official construction complaint process and preserve the license record, contract, payments, communications, permits, photographs and a clear timeline. CSLB can investigate licensing violations but does not guarantee financial recovery.
Match the License to the Person, Project and Payment
A safe CSLB check combines current status, legal identity, classification, personnel, bond, workers’ compensation, salesperson and contract review. Do not rely on a number printed on a truck, website or estimate without opening the live official record.
Applicants and licensees should use current CSLB forms, weekly processing times and fee pages rather than saved third-party instructions.
