Bakersfield Contractor Bond$25,000 CSLB — One Bond, Two Permit Counters
Every contractor licensed to work in Bakersfield needs the same $25,000 license bond required of every California contractor under Business and Professions Code Section 7071.6. There is no separate Bakersfield or Kern County contractor license bond. What changes locally is which counter processes your permit — City of Bakersfield or Kern County Public Works — a split that matters more here than almost anywhere else in the state because so much current construction volume sits on the unincorporated side of that line: utility-scale solar and storage build-out on former and active oilfield acreage.
The Kern County pattern: oilfield service contractors — electrical, civil, earthwork crews built around Kern River and Elk Hills field work — are adding CSLB's C-46 Solar Contractor classification to existing licenses rather than starting a new company. One CSLB license, one $25,000 bond, work in both sectors.
Why Kern County Is a Different Kind of CSLB Market Right Now
Kern County produces more oil than any other county in California, and that same land base — flat, high-solar-irradiance, already crossed by transmission corridors built for oilfield power draw — has made it one of the busiest utility-scale solar and storage construction markets in the country. Mortenson, the engineering-procurement-construction contractor on the Edwards & Sanborn Solar + Energy Storage project, lists the site at 864 megawatts of solar generation paired with 3,287 megawatt-hours of battery storage, built in Kern County with substantial completion reached in 2023. Separately, California Resources Corporation — one of the county's largest oil producers — has converted acreage at its Mt. Poso and Kern Front oilfields to solar generation, a combined roughly 30 megawatts originated by Luminia and now owned and operated long-term by Dispatch Energy.
None of that changes the bonding statute. A contractor pulling permits on a solar EPC subcontract in Kern County still files the identical $25,000 CSLB license bond under BPC Section 7071.6 that a residential remodeler in Bakersfield files. What it changes is classification strategy: crews built around C-10 electrical, C-12 earthwork, or general B oilfield-service work are adding CSLB's C-46 Solar Contractor classification to an existing license instead of forming a new entity, because the bond attaches to the license number and covers every classification on it. That is the practical opportunity this page exists to explain — and it is a Kern County-specific dynamic, not something you'll find on a coastal-market contractor bond page.
Kern County vs. City of Bakersfield — Which Counter Do You File With?
One CSLB bond, but two different local permitting authorities depending on the job site
Bakersfield & Kern County Contractor Permitting Layers
What's required, by which authority, and whether it involves a bond or security
| Layer | Authority | Applies When | Bond / Security | Governing Code |
|---|---|---|---|---|
| CSLB License Bond | Contractors State License Board (statewide) | Always — every CA-licensed contractor | $25,000 | BPC § 7071.6 |
| City Business Tax Certificate | City of Bakersfield Treasury Division | Job site inside Bakersfield city limits | No bond — tax registration only | BMC Ch. 5.02 |
| City Right-of-Way / Excavation Permit | City of Bakersfield Public Works | Excavating or working in a city street or right-of-way | Security/deposit set per permit | BMC Ch. 12.16 |
| Kern County Building Permit | Kern County Public Works — Building Inspection Division | Job site in unincorporated Kern County | No county bond — CSLB # required on application | Kern County Building Code |
| Kern County Business License | Kern County (regulatory licensing) | Only specific regulated/hazardous business types | Not required for ordinary licensed contracting | Kern County Code |
Rows 2-3 apply only to city-limit job sites; row 4 applies only to unincorporated county job sites. A contractor working both sides of the line may encounter either layer, never both at once on the same permit.

Inside Bakersfield City Limits
Building and trade permits route through the City of Bakersfield's Development Services. If your business operates in the city, Bakersfield Municipal Code Chapter 5.02 requires a business tax certificate from the Treasury Division, filed separately from your CSLB bond. If the scope touches a public street, sidewalk, or curb — trenching for underground electrical to a rooftop solar tie-in is a common trigger — BMC Chapter 12.16 "Construction Work in Streets" requires a written excavation permit and a security or deposit filed with Public Works before work starts, with a separate underground service alert obligation under BMC § 12.16.170.
Unincorporated Kern County
Most utility-scale solar, storage, and oilfield-adjacent work sits outside city limits, under Kern County Public Works. Permits are filed through the county's Accela citizen portal or in person at 2700 "M" Street, Suite 150 in Bakersfield, and the application requires your CSLB license number and expiration date. Kern County does not run a parallel contractor license-bond program — your statewide $25,000 CSLB bond satisfies the licensing side of a county permit. A general county business license is only required for specific regulated or hazardous business categories, not for ordinary licensed contracting.
The CSLB Layer: What BPC § 7071.6 Actually Requires
Before CSLB will activate a license — Class A, Class B, or any of the Class C specialty classifications, Bakersfield or anywhere else in California — the applicant must file a $25,000 surety bond. This is the same statewide floor CSLB has enforced since Senate Bill 607 raised it from $15,000, effective January 1, 2023. The bond is a three-party agreement: you (the licensee/principal), a Treasury-listed surety, and the public and CSLB as beneficiaries. It does not insure your work — it guarantees a fund consumers, employees, and the state can draw against for statutory violations, up to the bond's aggregate limit.
Official California Requirements
"A bond required by this section shall be in the amount of twenty-five thousand dollars ($25,000). The bond shall be executed by a sufficient surety... and shall be filed with the registrar by the licensee or applicant."California Contractors State License Board (CSLB) • California Business and Professions Code § 7071.6
The $25,000 figure applies uniformly across California — see the full CSLB bond page for claim-priority rules, the $7,500 non-priority claimant cap, and renewal timelines that apply to every CSLB licensee regardless of city.
Adding C-46 Solar to an Existing License: What Actually Changes
CSLB adopted the C-46 Solar Contractor classification in 1983, and it covers installing, modifying, maintaining, and repairing thermal and photovoltaic solar energy systems. A C-46 licensee is restricted to solar-specific scope and generally cannot perform other building trades except when directly necessary to complete a solar installation — the classification is narrow by design, authorized under 16 California Code of Regulations, Division 8, Article 3, with statutory grounding in Business and Professions Code Sections 7008 and 7059. To qualify, an applicant needs four years of verified journey-level experience plus a passing score on both the trade exam and the business-and-law exam.
What does not change is the bond. A Kern County contractor who already holds a CSLB license — say, a C-10 electrical or general B license built around oilfield facility work — and adds C-46 to that same license does not file a second $25,000 bond. The bond under BPC § 7071.6 attaches to the license number, and one license can carry multiple classifications simultaneously. This is why the classification switch has been administratively cheap for Kern County oilfield service firms moving into solar EPC subcontracting: no new entity, no new license fee cycle from scratch, no new bond — just an added classification exam and CSLB paperwork. The only scenario that adds a second bond obligation is an unrelated CSLB action, such as forming an LLC (which triggers the separate $100,000 employee/worker bond under BPC § 7071.6.5) or a disciplinary bond under BPC § 7071.8.
Adding a Classification or Starting Fresh — Same $25,000 Bond
Whether you're licensing a new Bakersfield entity or adding C-46 to an existing Kern County CSLB license, the bond math is identical.

CSLB $25,000 Bond — Annual Premium by Credit Tier
Based on a $25,000 bond amount
- 750+ FICO (excellent)Rate: 0.5% – 1.0%$125 – $250
- 680 – 749 (good)Rate: 1.0% – 2.0%$250 – $500

- Below 620 (challenged)Rate: 4.0% – 10%+$1,000 – $2,500
Premium is quoted on your personal/business credit, not on your job location. A Bakersfield residential remodeler and a Kern County solar EPC sub with the same credit tier pay the same rate on the $25,000 bond.
What's not in this number: the CSLB premium above covers only the $25,000 license bond. If your Bakersfield job triggers a BMC § 12.16 right-of-way security deposit, that amount is set by Public Works per permit and is typically refundable cash or a separate performance-style instrument — not priced by credit tier the way the CSLB bond is. Budget it as a project cost, not a recurring annual premium. See our surety bond cost guide for how credit-tier pricing works across bond types.
