Contractor Licensing (CSLB)
Understanding California contractor license requirements and protections
1What is the Contractors State License Board (CSLB) and what do they do?
▼The Contractors State License Board (CSLB) is a California state agency that licenses and regulates the construction industry. Their key functions include:
- Licensing: Issue and renew contractor licenses across 44+ classifications
- Investigation: Investigate consumer complaints against contractors
- Enforcement: Discipline contractors through fines, suspension, or license revocation
- Public Database: Maintain searchable records of all licensed contractors
- Consumer Protection: Help consumers recover money through bond claims
Under Business & Professions Code 7031, any construction work over $500 (combined labor and materials) requires a CSLB license. Working without a license is a misdemeanor under B&P 7028.

2How do I verify if a contractor is licensed in California?
▼Visit cslb.ca.gov and use the "Check a License" feature. You can search by:
- License number
- Business name
- Individual name
The database shows:
- Current status: Active, expired, suspended, or revoked
- License classification: Type of work authorized (C-10 electrical, C-36 plumbing, etc.)
- Bond information: Surety bond status and company
- Workers' comp: Insurance status or exemption
- Complaint history: Past complaints and disciplinary actions
Pro Tip: For legal claims, request a "Certified License History" from CSLB for ~$15. This provides official proof of license status during specific dates.
3Can I recover money from an unlicensed contractor in California?
▼Yes - and this is one of California's strongest consumer protections.
Under Business & Professions Code 7031(b), you can recover ALL money paid to an unlicensed contractor through "disgorgement" - even if the work was completed perfectly. Key points:
- Full refund: The contractor must return every dollar you paid
- No offset: The contractor CANNOT reduce this by the value of work performed
- Quality irrelevant: Even excellent work doesn't protect an unlicensed contractor
- No counterclaims: Under B&P 7031(a), unlicensed contractors cannot sue you for payment
The California Supreme Court confirmed this in MW Erectors, Inc. v. Niederhauser Ornamental & Metal Works Co. (2005) 36 Cal.4th 412.
Example: You paid $50,000 for a kitchen remodel. The contractor's license expired during the project. You can recover all $50,000 - even if the kitchen is beautiful.
4What is the $500 licensing threshold and what does it mean?
▼Under Business & Professions Code 7048, any construction project with combined labor and materials exceeding $500 requires a licensed contractor.
- Under $500: Handymen can legally perform work without a license
- Over $500: A CSLB license is required
- No splitting: Projects cannot be artificially divided to stay under the threshold
This threshold includes:
- All labor costs
- All material costs
- Subcontractor costs
- The total project, not individual payments
Warning: A "handyman" who takes on a $2,000 project is operating illegally and you can recover all money paid under B&P 7031.
Abandoned Projects
What to do when your contractor stops showing up
5What constitutes project abandonment by a contractor?
▼Under Business & Professions Code 7107, a contractor has abandoned a project if they:
- Fail to complete the work
- The project is delayed for an unreasonable amount of time
- No substantial progress is being made
Courts typically consider these factors:
- 30+ days without progress: Generally considered unreasonable delay
- No communication: Contractor not returning calls or messages
- Equipment removed: Tools and materials taken from the site
- Started another job: Evidence contractor is working elsewhere
- Subcontractors unpaid: Subs stopping work due to non-payment
Document Everything: Take dated photos, save all texts/emails, and create a timeline. This evidence is crucial for CSLB complaints and court.
6What should I do if my contractor abandons the project?
▼Take these steps immediately:
- Document the site: Take comprehensive photos and videos with dates
- Send written notice: Demand the contractor return to work within 10 days via certified mail
- Check license status: Verify at cslb.ca.gov - if unlicensed, you have additional recovery options
- Get repair/completion estimates: Obtain 2-3 written bids from licensed contractors
- File a CSLB complaint: This creates an official record and may trigger investigation
- File a bond claim: Claim against the contractor's $25,000 surety bond
- Consider small claims court: For damages up to $12,500
If fraud is involved (e.g., contractor took large payment and never started work), report to the District Attorney's office and local police.
Poor Workmanship
Standards, remedies, and your rights when work is defective
7What are the standards for "good workmanship" in California?
▼Construction work must meet or exceed:
- California Building Code (Title 24): Minimum construction standards
- Manufacturer specifications: Installation requirements for products used
- Industry standards: Accepted practices in the trade
- Contract specifications: What your agreement requires
Under Civil Code 896 (SB 800), residential construction must meet specific functionality standards for:
- Water intrusion and drainage
- Structural integrity
- Soil and foundation issues
- Fire protection systems
- Plumbing, electrical, and HVAC systems
Key Point: Deviation from these standards constitutes defective work regardless of the contractor's excuses about "that's how we always do it."
8What remedies do I have for defective contractor work?
▼Damages you can recover include:
- Cost of repair: What another contractor charges to fix the defects
- Cost of completion: Finishing unfinished work
- Diminution in value: If defects permanently reduce property value
- Return of overpayments: Money paid for work not performed
- Consequential damages: Hotel costs if home uninhabitable, lost rent, storage fees
- Disgorgement: Full refund if contractor was unlicensed (B&P 7031)
Additional remedies:
- Attorney's fees (if your contract includes a fee provision)
- CSLB complaint (may result in license discipline)
- Bond claim (up to $25,000)
9What contractor warranties are required by California law?
▼Under Civil Code 896, residential construction has implied warranties regardless of what's in your contract:
- 1 year: Fit and finish (paint, flooring, cosmetic issues)
- 2 years: Plumbing, electrical, mechanical, and HVAC systems
- 4 years: Most other defects (roofing, windows, doors)
- 10 years: Structural defects (foundation, framing, load-bearing elements)
These warranties cannot be waived. Additional warranties may be provided in your contract or by product manufacturers.
Pro Tip: Keep all warranty documents, receipts, and maintenance records. Document any defects with dated photos as soon as you notice them.
Contract Requirements
What must be in writing and your cancellation rights
10What must be included in a California home improvement contract?
▼Under Business & Professions Code 7159, contracts for home improvement over $500 must include:
- Contractor information: Legal name, license number, business address, and phone
- Project description: Detailed scope of work and materials to be used
- Contract price: Total price or how price will be calculated
- Payment schedule: When payments are due (with down payment limits)
- Start and completion dates: Approximate timeline
- 3-day cancellation notice: Required statement of your right to cancel
- Cancellation form: A form you can use to cancel
- Bond information: Contractor's surety bond details
- Mechanics lien warning: Notice about lien rights
Contracts missing required elements may be voidable, and the contractor may face CSLB discipline.
11What is the 3-day right to cancel for home improvement contracts?
▼Under Business & Professions Code 7159 and Civil Code 1689.5-1689.14:
- 3 business days: You can cancel most home improvement contracts signed at your home
- No penalty: Full refund of any payments made
- Written form required: Contractor must provide a cancellation form
- Extended period: If no form provided, cancellation right extends indefinitely until the form is given
Exceptions (where 3-day rule may not apply):
- Emergency repairs you requested
- Contracts signed at the contractor's office
- You initiated contact and requested immediate work
To cancel: Sign and date the cancellation form, then mail or deliver it to the contractor within 3 business days. Keep a copy for your records.
12What are change orders and how should they be handled?
▼Change orders modify the original contract's scope or price. Under B&P 7159:
- Should be in writing: Signed by both parties before work begins
- Must specify: The additional work, additional cost, and timeline impact
- Verbal change orders: Enforceable but harder to prove - avoid when possible
Protect yourself from "scope creep":
- Get all changes in writing before authorizing additional work
- Request itemized pricing for change orders
- Document any verbal agreements immediately in writing via email
- Keep a running total of all change orders
Red Flag: If a contractor consistently "discovers" problems requiring expensive change orders, get a second opinion from another licensed contractor.
Payment Disputes
Down payments, withholding, and protecting your money
13How much can a contractor collect as a down payment in California?
▼Under Business & Professions Code 7159.5:
- Maximum down payment: $1,000 OR 10% of the contract price, whichever is LESS
- Progress payments: Must be tied to work actually completed
- Final payment: Should not be made until work passes inspection
Example:
- $8,000 contract = max $800 down payment (10%)
- $15,000 contract = max $1,000 down payment (cap)
- $50,000 contract = max $1,000 down payment (cap)
Warning: A contractor demanding a larger down payment is violating CSLB rules. This is a major red flag and grounds for complaint.
14Can I withhold payment from a contractor for defective work?
▼Yes, you can withhold payment proportional to the defects. Best practices:
- Document the defects: Photos, videos, dates, descriptions
- Get repair estimates: 2-3 written bids from licensed contractors
- Send written notice: Explain what you're withholding and why
- Be proportional: Don't withhold more than needed to fix the problems
- Offer to pay undisputed amounts: Pay for completed work that meets standards
Example: On a $30,000 project with $5,000 in defects, pay $25,000 and withhold $5,000 pending repairs. Document your reasoning in writing.
15How do I protect myself from subcontractor liens?
▼Even if you pay your general contractor, unpaid subcontractors can lien your property. Protect yourself:
- Track preliminary notices: When you receive 20-day notices, note who sent them
- Request lien waivers: Get conditional waivers before each progress payment
- Use joint checks: Issue checks payable to both GC and subcontractor
- Verify payments: Ask for proof subs are being paid
- Final lien waivers: Get unconditional waivers from all parties before final payment
California law provides lien waiver forms in Civil Code 8132-8138. Use the statutory forms for maximum protection.
Mechanic's Liens
Understanding, preventing, and removing construction liens
16What is a mechanic's lien and how does it affect homeowners?
▼A mechanic's lien (under Civil Code 8400-8494) is a claim against your property for unpaid construction work.
Who can file a lien:
- General contractors
- Subcontractors
- Material suppliers
- Equipment lessors
- Laborers
Impact on homeowners:
- Creates a cloud on your property title
- May block sale or refinancing
- Lien holder can foreclose if not resolved
- Appears in title searches
Important: Under B&P 7031, unlicensed contractors CANNOT file valid mechanic's liens.
17What is the preliminary 20-day notice for mechanic's liens?
▼Under Civil Code 8200-8216, most parties (except general contractors with direct contracts) must serve a preliminary 20-day notice to preserve their lien rights.
What it means for you:
- Alerts you that someone (subcontractor, supplier) is providing labor or materials
- Does NOT mean a lien will be filed
- Identifies potential lien claimants
- Required before they can file a lien
When you receive one:
- Keep it on file
- Verify the general contractor is paying this party
- Request lien waivers as payments are made
- Consider joint checks for these parties
18How do I remove a mechanic's lien from my property?
▼Options to remove a lien:
- Pay the claim: Get a signed lien release recorded
- Negotiate: Settle for less and get a release
- Motion to release: If lien is procedurally defective (wrong amount, late filing, etc.)
- Post a release bond: Under
Civil Code 8424, bond replaces the lien on your property - Wait for expiration: Liens expire 90 days after recording if no lawsuit is filed (
Civil Code 8460) - Challenge in court: If you dispute the claim, let them sue and defend
Defective liens can often be released through a motion. Common defects include: wrong property description, incorrect amounts, missed deadlines, or filed by unlicensed contractor.
19Can an unlicensed contractor file a mechanic's lien in California?
▼No. Under Business & Professions Code 7031(a), an unlicensed contractor cannot bring any legal action for compensation, including filing a mechanic's lien.
If an unlicensed contractor files a lien:
- The lien is void and unenforceable
- You can file a motion to release the lien
- You may recover attorney's fees for removing it
- The contractor may face additional penalties for wrongful lien
First Step: Verify license status at cslb.ca.gov. If the contractor was unlicensed during the work, you have strong grounds to remove the lien.
CSLB Complaints
Filing complaints and what to expect from the process
20How do I file a complaint with the CSLB?
▼File your complaint:
- Online: cslb.ca.gov (fastest method)
- By mail: Download form from website
- By phone: (800) 321-CSLB (2752)
Include in your complaint:
- Contractor's name, license number, address
- Project address and description
- Detailed timeline of events
- Payment records (checks, receipts, invoices)
- Photos of defective work
- Copies of contracts and change orders
- All correspondence (emails, texts, letters)
- Repair estimates from other contractors
Tip: Be specific and factual. Include dates, amounts, and documentation. The more complete your complaint, the better the investigation.
21What happens after I file a CSLB complaint?
▼The CSLB process:
- Acknowledgment: You receive confirmation of your complaint
- Review: CSLB staff review for jurisdiction and merit
- Contact contractor: Contractor is notified and asked to respond
- Investigation: If warranted, a full investigation begins
- Resolution: Mediation, settlement, or formal action
Possible outcomes:
- Mediation leading to settlement
- Citation and fine against contractor
- License suspension or revocation
- Order to pay restitution
- Referral to District Attorney for criminal prosecution
- Bond claim assistance
Timeline: Investigations typically take 6-18 months. CSLB prioritizes cases with larger damages and patterns of misconduct.
Bond Claims
Recovering money from a contractor's surety bond
22What is a contractor's bond and how do I make a claim?
▼California licensed contractors must maintain a $25,000 surety bond that protects consumers.
To make a bond claim:
- Get bond company info: Look up at cslb.ca.gov under contractor's license
- Send written claim: Include your name, contractor info, amount claimed, and supporting documents
- Provide documentation: Contract, payments, photos, estimates
- Bond company investigates: They review the claim and may contact the contractor
- Resolution: Payment, denial, or partial payment
Important notes:
- Total bond is $25,000 - may have multiple claimants
- File claims promptly to maximize recovery
- Bond companies often settle valid claims
- If denied, you can sue the bond company
Small Claims Court & Demand Letters
DIY legal options for contractor disputes
23Can I sue a contractor in small claims court in California?
▼Yes - small claims court is excellent for contractor disputes.
Key details:
- Limit: $12,500 for individuals
- Filing fee: $75-$100 depending on amount
- No attorney needed: You represent yourself
- Fast: Typically heard within 30-70 days
What to bring to court:
- Written contract
- Payment records (checks, credit card statements)
- Photos of defective work (before and after)
- Repair estimates from licensed contractors
- CSLB records (license status, history)
- All correspondence with contractor
- Your demand letter and any response
24What should I include in a demand letter to a contractor?
▼Your demand letter should include:
- Your information: Name, address, contact info
- Contractor information: Name, license number, address
- Project description: Address, scope of work, dates
- What went wrong: Specific problems, defects, or breach
- Damages: Itemized list with documentation
- Legal citations: B&P 7031, 7107, 7159 as applicable
- Exact amount demanded: Clear total with breakdown
- Deadline: 10-15 days to respond
- Consequences: Legal action, CSLB complaint, bond claim
Send via certified mail with return receipt to prove delivery. Keep a copy for your records.
25What is the statute of limitations for contractor disputes in California?
▼Key deadlines:
- 4 years: Breach of written contract (
CCP 337) - 2 years: Oral contracts (
CCP 339) - 3-4 years: B&P 7031 unlicensed contractor claims
- 4 years: Patent (obvious) defects (
CCP 337.1) - 10 years: Latent (hidden) defects (
CCP 337.15)
The "discovery rule" may extend some deadlines - the clock starts when you discovered or should have discovered the problem, not when the work was done.
Don't delay! Evidence deteriorates, witnesses forget, and contractors disappear. File claims promptly.
Permits & Inspections
Who's responsible and why they matter
26Who is responsible for obtaining building permits - homeowner or contractor?
▼Under Business & Professions Code 7110, the contractor is responsible for obtaining required permits unless the contract explicitly states otherwise.
Consequences of unpermitted work:
- CSLB violation against the contractor
- Work may need to be torn out and redone
- Problems selling your home (title issues)
- Insurance may not cover unpermitted work
- Safety risks from uninspected work
- Fines from local building department
Always verify: Before work begins, confirm permits have been pulled. You can check with your local building department.
27Can I do my own contractor work without a license?
▼Under B&P 7044, homeowners can perform work on their own primary residence without a contractor's license.
Requirements:
- Must be your primary residence
- Work must still meet building codes
- Permits still required where applicable
- Cannot use exemption for investment properties
- Cannot help friends/family under this exemption
Risks of DIY work:
- No warranty protection
- Insurance may not cover DIY work
- May affect resale value
- Liability for injuries to others
When to Hire a Lawyer
DIY vs. professional legal help
28When should I hire a lawyer for a contractor dispute?
▼Consider hiring a lawyer if:
- Damages exceed $12,500: Beyond small claims court limit
- Mechanic's liens involved: Complex procedures to remove
- Contractor disputes license status: May need certified records
- Structural defects: May need expert witnesses
- Contractor filed lawsuit: You need representation
- SB 800 claims: Complex pre-litigation requirements
- Multiple contractors involved: Complex liability issues
- Insurance bad faith: Denied claims for covered work
Many attorneys offer free consultations to evaluate your case. Ask about contingency fees (no fee unless you win) for larger claims.
29What is the SB 800 pre-litigation process for construction defects?
▼For residential construction defects, Civil Code 910-938 (SB 800) requires specific steps before filing a lawsuit:
- Written notice: Send detailed notice of defects to builder
- Acknowledgment: Builder has 14 days to acknowledge
- Inspection: Builder has 30 days to inspect
- Offer to repair: Builder has 30 days to offer repair
- Your response: Accept, reject, or negotiate the offer
If builder doesn't respond or you reject the offer, you can proceed with litigation after the process is complete.
Skipping this process can result in your lawsuit being dismissed. Follow the requirements carefully.
30What is the "substantial compliance" defense to unlicensed contractor claims?
▼Under B&P 7031(e), a contractor may avoid disgorgement if they prove ALL of the following:
- Previously licensed: They held a valid license before the work
- Good faith belief: They reasonably believed they were still licensed
- Prompt action: They quickly reinstated upon discovering the lapse
- Unjust result: Requiring full disgorgement would be inequitable
Courts apply this very narrowly. It does NOT apply if:
- The contractor was never licensed
- The license lapsed for more than a brief period
- The contractor knew or should have known about the lapse
- There's a history of license violations
Burden of proof is on the contractor to prove substantial compliance - you don't have to disprove it.
