Need a Concrete Contractor Bond?
Fast approval in all required states. Treasury-certified carriers. Most bonds issued same day for qualified applicants.
Most states do not have a dedicated “concrete contractor” license class. Unlike electrical or plumbing work — which most states regulate under dedicated trade-specific boards — concrete work is typically licensed under general contractor, specialty contractor, or residential contractor categories. This means the bond requirement that applies to you depends less on the word “concrete” and more on which classification your state uses.
Dedicated Concrete License
State issues a specific concrete or cement work classification.
Examples: California C-8, New Mexico GS-4, Virginia CEM specialty
Specialty Contractor Category
Concrete falls under a broader specialty contractor or trade contractor registration.
Examples: Washington (specialty registration), Alaska (specialty registration), Oregon CCB
General Contractor License
Concrete work included under general contractor or residential contractor licensing — no trade-specific classification.
Examples: Arizona ROC, Nevada NSCB, Minnesota DLI residential
Practical consequence: A concrete contractor in California needs a California C-8 license and a $25,000 CSLB bond. The same contractor doing the same flatwork in Arizona needs an Arizona ROC license with a volume-based bond ($2,500 to $50,000), not a concrete-specific bond. In Texas, there is no statewide license requirement for concrete contractors at all — bonding is entirely local. This guide covers every state's applicable requirement.
Who Is Affected
- Concrete contractors registered as specialty contractors with WA LNI
- Flatwork, stamped concrete, decorative concrete specialists
- General contractors performing concrete work saw a separate increase to $30,000
How the Phased Rollout Worked
Washington LNI phased the increase over renewal cycles rather than requiring immediate replacement bonds. Contractors updated their bond amount at their next registration renewal. Bonds renewed after July 1, 2024 must reflect the new $15,000 minimum. Existing bonds below $15,000 remaining from prior renewals were permitted to run until expiration.

Cost impact: A Washington concrete specialty contractor with good credit (700+ FICO) previously paid approximately $60-$120 per year on a $6,000 bond. At $15,000, the same contractor now pays approximately $75-$300 per year — a meaningful increase, but still among the lowest bond costs in the country. Calculate your exact premium →
California
C-8 Concrete Contractor Classification
Licensing Body: California Contractors State License Board (CSLB)
Classification: C-8 — covers all concrete forming, pouring, placing, finishing; mass concrete, pavement, flatwork, screeds
Bond Statute: Cal. Bus. & Prof. Code §7071.6
Bond Effective: January 1, 2023 (increased from $15,000 per SB 607)
C-8 Unique Requirement
All active C-8 concrete contractors must carry workers' compensation insurance even if they have zero employees. This is one of a handful of CSLB classifications with this mandatory WC requirement — most other trades can self-certify as sole owner exempt. A lapse in WC coverage triggers automatic license suspension.
CSLB Bond Requirements (cslb.ca.gov) → | Also see: California contractor license bond details
Washington
Specialty Contractor Registration
Licensing Body: WA Dept. of Labor & Industries (L&I)
Category: Specialty contractor (single-trade registration)
Bond Statute: RCW 18.27.040
Prior Amount: $6,000 (unchanged since 2001)
Concrete contractors who register as specialty contractors with WA LNI are subject to this bond. Contractors who perform multiple trades register as general contractors and face a separate $30,000 bond. Registration (not full licensure) is Washington's model; the bond is filed continuously.
Oregon
CCB License Endorsements (2024 Increase)
Licensing Body: Oregon Construction Contractors Board (CCB)
Authority: ORS Ch. 701
2024 Change: HB 2922 increased all bonds by $5,000 effective Jan. 1, 2024
Endorsement Bond Tiers (Effective Jan. 1, 2024)
- Residential Limited: $15,000
- Residential General: $25,000
- Commercial General Level 2: $25,000
- Commercial General Level 1: $80,000
Concrete contractors register under the endorsement matching their project scope (residential vs. commercial).
Arizona
ROC Specialty Contractor — Volume-Based Bond
Licensing Body: Arizona Registrar of Contractors (ROC)
Statute: ARS §32-1152
Concrete work falls under the Commercial Specialty Contractor classification. Bond amount is determined by your estimated annual gross volume — not a flat amount.
Volume-Based Bond Tiers
Arizona uses a graduated model — higher-volume businesses carry more bond coverage
- Lowest volume tier: $2,500
- Mid-volume tier: ~$10,000–$25,000
- Highest volume tier: $50,000
Bond must be continuous — no expiration date.
Nevada
Nevada State Contractors Board — Board-Determined Amount
Licensing Body: Nevada State Contractors Board (NSCB)
Statute: NRS 624.270
Nevada's Board determines the bond amount individually for each licensee at the time of license approval based on financial responsibility, experience, monetary limit, and the magnitude of operations. There is no fixed schedule — the Board sets your specific amount.
What Drives Your Bond Amount
- • Monetary limit on your license (project dollar cap)
- • Your demonstrated financial responsibility
- • Scope and volume of operations
- • Experience in the trade
- • Character assessment by the Board

New Mexico
GS-4: Concrete, Cement, Walkways & Driveways
Licensing Body: NM Regulation and Licensing Dept., Construction Industries Division
Classification: GS-4 — specifically covers mixing, pouring, placing, and finishing concrete; includes excavation, formwork, and reinforcement
Statute: 14.6.3 NMAC; NMSA 1978, § 60-13-49
GS-4 Experience Requirement
Two years of practical trade experience, including one year at foreman level. New Mexico is notable for having a dedicated concrete classification (GS-4) with a fixed $10,000 bond — one of the few states that calls out concrete work explicitly.
Alaska
Specialty Contractor Registration
Licensing Body: AK Dept. of Commerce, Community & Economic Development (DCCED)
Statute: AS 08.18.071
Concrete contractors register as specialty contractors in Alaska. The $10,000 bond requirement applies to all specialty contractor registrations. General contractors face a higher $25,000 requirement.
Source: AK DCCED Construction Contractors (commerce.alaska.gov) →
Virginia
CEM Specialty Designation — Class A & B Only
Licensing Body: Virginia Dept. of Professional & Occupational Regulation (DPOR), Board for Contractors
Specialty Code: CEM (Cement Contracting)
Statute: Va. Code §§ 54.1-1106, 54.1-1108
License Class Matters
- Class A (over $120K/year): $50,000 bond OR proof of $45,000 net worth
- Class B ($10K–$120K/year): $15,000 minimum net worth; bond optional as substitute
- Class C (under $10K/year): No bond required

South Carolina
Residential Specialty Contractor Registration
Licensing Body: SC Dept. of Labor, Licensing & Regulation — Residential Builders Commission
Statute: SC Code § 40-59-220
South Carolina residential specialty contractors (which include concrete and flatwork specialists) must obtain a $5,000 bond when a project for an individual property owner exceeds $5,000 in total cost. The bond is issued in the individual contractor's name, not a company name. Electronic bond submission accepted since 2020.
Iowa
Out-of-State Contractor Registration
Licensing Body: Iowa Dept. of Inspections, Appeals & Licensing (DIAL)
Iowa requires all construction contractors earning $2,000 or more annually from construction work to register. Out-of-state contractors must file a $25,000 bond guaranteeing payment of Iowa taxes, penalties, and other state obligations. In-state concrete contractors register without a bond requirement but must carry insurance.
| State | Bond Amount | Classification | Authority | Statute |
|---|---|---|---|---|
| Alaska | $10,000 | Specialty contractor | AK DCCED | AS 08.18.071 |
| Arizona | $2,500–$50,000 | Commercial specialty (volume-based) | AZ ROC | ARS §32-1152 |
| California | $25,000 | C-8 Concrete Contractor | CA CSLB | Bus. & Prof. Code §7071.6 |
| Iowa | $25,000* | Out-of-state registration | IA DIAL | Iowa Code Ch. 91C |

| New Mexico | $10,000 | GS-4 Concrete/Cement | NM RLD CID | 14.6.3 NMAC |
| Oregon | $15,000–$80,000 | CCB endorsement tier | OR CCB | ORS Ch. 701 |

| Washington | $15,000 | Specialty contractor | WA LNI | RCW 18.27.040 |
* Iowa $25,000 bond applies to out-of-state contractors only. SC $5,000 bond triggers when individual project exceeds $5,000. Amounts verified May 2026 from official state sources.
Florida: Financial Responsibility Instead of Bond
Florida CILB does not require a standard license bond for concrete contractors. Instead, applicants must demonstrate financial responsibility by submitting a credit report showing a FICO score of 660 or higher. Contractors who designate a Financially Responsible Officer (FRO) must post a $100,000 bond or irrevocable letter of credit for that individual. Active licensees must maintain minimum liability insurance ($100,000/$25,000 for most contractor categories).

Texas: No State License for Concrete Work — Local Requirements Only
Texas does not have a statewide contractor license for general or concrete contractors. The Texas Dept. of Licensing and Regulation (TDLR) regulates specific trades (air conditioning, electrical, plumbing) but not concrete contracting. Bond requirements are entirely municipal — for example, Houston and Dallas have their own concrete contractor registration programs with local bond requirements. Contractors must check their specific city/county requirements.
States with No Concrete Contractor Bond Requirement
* Minnesota does not require a license bond for residential building contractors — instead, the Contractor Recovery Fund provides consumer protection. “Local only” states require bonds only at the city or county level; always verify municipal requirements in your specific work area.
Concrete contractor bonds are typically among the more affordable surety bonds in the industry — even at California's $25,000 level. Annual premiums for a $25,000 bond range from $125 for contractors with excellent credit to $3,750 for contractors with poor credit. Washington's $15,000 specialty bond runs $75–$300 per year for most applicants.
Bond cost is primarily determined by personal credit score, not bond amount alone. Unlike insurance, surety underwriting treats the bond as a credit product — the surety is betting you won't generate a claim it has to pay. For more on how credit drives pricing across all contractor bonds, see the contractor license bond cost by state guide or the surety bond cost overview.
Premium Rate Table by Credit Score
| Credit Tier | FICO Range | Annual Rate | CA $25K Bond | WA $15K Bond | NM $10K Bond |
|---|---|---|---|---|---|
| Excellent | 700+ | 0.5% – 2% | $125 – $500 | $75 – $300 | $50 – $200 |
| Good | 650–699 | 2% – 5% | $500 – $1,250 | $300 – $750 | $200 – $500 |
| Fair | 600–649 | 5% – 10% | $1,250 – $2,500 | $750 – $1,500 | $500 – $1,000 |
| Challenged | <600 | 10% – 15% | $2,500 – $3,750 | $1,500 – $2,250 | $1,000 – $1,500 |
What Causes Concrete Contractor Bonds to Cost More Than Table Rates
- • Prior bond claims — any claim history routes the application to specialty “hard-to-place” markets at 10–15% regardless of credit score
- • Delinquent tax liens — federal or state tax liens must be on a payment plan or resolved before most sureties will quote
- • License discipline history — prior CSLB or state board actions increase rate or require collateral
- • New business with no financials — startups without 2 years of business tax returns face higher scrutiny, especially for bonds over $50,000 (Nevada)
Multi-Year Bond Discount Strategy
Many sureties offer 5–15% discounts on 2- or 3-year terms. For a California concrete contractor paying $500/year, a 3-year bond at $1,275 total saves $225 and eliminates two renewal cycles. This is particularly valuable if you just qualified at a good rate — locking in that rate for 3 years guards against future credit dips affecting your renewal cost.
Full breakdown of surety bond pricing factors →One situation that catches California C-8 concrete contractors off guard: the mandatory workers' compensation requirement that applies even to sole proprietors with no employees. Most contractor classifications can file a self-exemption with CSLB if they have no employees. C-8 cannot. The CSLB automatically suspends a C-8 license when the WC insurance lapses — and because WC premiums are tied to payroll, a sole owner with minimal payroll often tries to skip it entirely and loses their license.
We've seen contractors in this situation who didn't realize their license was suspended until they tried to pull a permit for a new job. Reinstatement requires obtaining both a new active WC policy and filing proof with CSLB before the license reactivates — a process that typically adds 2–4 weeks to the timeline.
The practical advice: if you're a C-8 sole proprietor, shop for a minimum-premium WC policy designed for owner-operators — some carriers offer these in the $1,500–$2,500 annual range for sole owners with low payroll. Set your WC renewal date to align with your CSLB license renewal date so both renew together. If either lapses, the license goes with it.

Concrete contractor bonds are simpler to obtain than most surety bonds because the amounts are modest and claims frequency is relatively low. For most applicants with good credit, the process takes hours rather than days.
Confirm Your State's Exact Bond Amount
Use the table above to identify your state's required bond amount and the licensing body where you'll file. Arizona requires you to know your estimated annual gross volume before you can determine the correct bond tier. Nevada assigns your amount at the time of license approval — you'll learn it during the application process.
Apply Through a Treasury-Certified Surety
Most states require bonds from Treasury-certified carriers. Surety agencies (like BuySuretyBonds.com) access 10–20 carriers simultaneously and get you the best rate through competition — direct carrier applications lock you into a single carrier's rates. For bonds under $50,000 with good credit, expect a 5-minute application with same-day or next-business-day approval.
Verify carrier certification: U.S. Treasury Certified Companies List →
File With Your Licensing Board
California CSLB: file bond with license application; CSLB requires the bond to be in place before issuing an active license or processing renewals. Washington LNI: continuous bond filed as part of the contractor registration. Oregon CCB: bond filed with CCB endorsement application. Most states accept electronic bond submissions today, but confirm your state's specific preference.
Keep the Bond Active Through Renewals
Concrete contractor license bonds must remain continuously active — a lapse triggers license suspension. Set a calendar reminder 60 days before your bond renewal date. If you're renewing for the first time since Washington's July 2024 increase, confirm the new bond meets the $15,000 minimum. For more on managing renewal cycles, see the contractor license bond renewal guide.

Get Instant Quote →Does California require a separate bond for a C-8 concrete contractor license?
Yes. California CSLB requires a $25,000 contractor license bond for all classifications, including C-8 concrete. Unique to C-8: all active licensees must also carry workers' compensation insurance, even with no employees — this is unusual among California specialty trades. The bond is governed by Cal. Bus. & Prof. Code §7071.6.
Washington raised its specialty contractor bond in 2024 — does that affect concrete contractors?
Yes. Effective July 1, 2024, Washington increased the specialty contractor bond from $6,000 to $15,000 — a 150% increase, the first adjustment since 2001. Concrete contractors registered as specialty contractors with WA LNI are directly affected. General contractors saw a separate increase to $30,000. See the official LNI announcement.
Which states have a dedicated concrete contractor license classification?
Very few. California (C-8 Concrete Contractor), New Mexico (GS-4 Concrete/Cement), and Virginia (CEM Cement Contracting specialty designation) are the primary examples. Most states fold concrete work under general contractor, residential contractor, or specialty contractor registrations without naming concrete explicitly. The practical effect: the bond amount and licensing body depend on the broader category, not the specific trade.
Can a concrete contractor in a no-bond state still be required to post a bond?
Yes — in two scenarios. First, project-specific performance bonds and payment bonds may be required by owners regardless of state license bond rules — federal projects over $150,000 always require Miller Act bonds. Second, cities and counties in states like Ohio, Illinois, and Texas impose local bond requirements. Always verify your specific city's rules in addition to state requirements.
Why did Washington double the concrete contractor bond requirement?
Washington LNI cited the need to restore consumer protection after two decades without adjustment. The $6,000 bond amount set in 2001 had significantly eroded in real value. LNI phased the increase over renewal cycles to minimize disruption to more than 67,000 registered contractors. The change applies to all specialty contractor registrations, not concrete specifically — concrete contractors simply fall in that category.
How much does a concrete contractor bond actually cost per year?
For a California $25,000 bond with good credit (700+ FICO): approximately $125–$500 per year. For Washington's $15,000 bond: approximately $75–$300 per year. Rates increase significantly with credit challenges — a 580 FICO on a $25,000 bond could run $2,500–$3,750 annually.
