California C-27 Landscaping Contractor License Requirements (2026)

The Class C-27 Landscaping Contractor license issued by the California Contractors State License Board (CSLB) is required for any landscaping business performing work valued at $500 or more in labor and materials. The C-27 scope covers installation, maintenance, and repair of architectural landscape features including grading, drainage, irrigation, planting of trees and shrubs, sodding, hardscape (walkways, decks, fences, patios), and low-voltage landscape lighting. Any application of restricted-use or commercial pesticides requires a separate California Department of Pesticide Regulation (DPR) Qualified Applicator License (QAL) or Qualified Applicator Certificate (QAC).

Regulatory Oversight

Contractors State License Board (CSLB) administers and enforces this credential under the authority of California Business & Professions Code §7000 et seq. (Contractors State License Law). The CSLB licenses and regulates contractors in 44 license classifications, investigates consumer complaints, enforces contractor license law, and prosecutes unlicensed activity through administrative, civil, and criminal action.

Who May Apply

To qualify, an applicant must have reached age 18 and hold a valid Social Security Number or Individual Taxpayer Identification Number (ITIN). No California residency requirement. Out-of-state applicants may apply.

Good moral character

Applicants must disclose any prior criminal conviction. CSLB conducts a criminal background investigation under Cal. B&P Code §480 and may deny licensure for offenses substantially related to the qualifications, functions, or duties of a contractor.

Background investigation

Mandatory fingerprinting through Live Scan (in-state) or hard cards (out-of-state). Results are reviewed by both the California Department of Justice and the Federal Bureau of Investigation.

Disqualifying conditions

Felony convictions substantially related to construction or financial responsibility
Prior license revocation in California or any other jurisdiction
Outstanding court-ordered restitution to a contractor or homeowner

Required Experience and Education

Eligibility requires 4 years of journeyman, foreman, supervising employee, contractor, or owner-builder performing C-27 landscaping work, documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

CSLB Certification of Work Experience (form 13A-11) signed under penalty of perjury by a qualified verifier
W-2 statements, pay stubs, and tax returns covering the four-year qualifying period
Project list with addresses and dollar values

Education substitution

Up to three of the four years may be credited for accredited horticulture, landscape architecture, or ornamental horticulture coursework and approved apprenticeship completion.

Examination Requirements

PSI Services LLC (under contract to CSLB) runs the examination for this credential. Issuance is contingent on passing every part below:

Law and Business — 115 questions, 210 minutes, passing score 72%
C-27 Landscaping Trade Examination — 100 questions, 210 minutes, passing score 72%

Examination fee: Included in the $450 CSLB application fee.

Retake policy: Failed parts may be re-taken every 21 days for an $100 rescheduling fee. Application remains valid 18 months.

Insurance and Financial Requirements

Licensure is conditioned on filing a $25,000 contractor license surety bond with the CSLB.

General liability

No statutory minimum for sole proprietors and corporations, but commercial general liability is required for limited liability company (LLC) licensees in the amount of $1,000,000 per occurrence (and an aggregate policy limit increased by $100,000 for each additional employee, up to a maximum of $5,000,000).

Workers' compensation

Workers' compensation insurance is mandatory for any licensee with one or more employees. Sole-owner licensees with no employees may file a Workers' Compensation Exemption Certification; certain license classifications cannot claim exemption.

Additional financial requirements

LLC applicants must additionally maintain an LLC employee/worker bond of $100,000 to protect employee wages and fringe benefits.

Licensing Fees

Application (non-refundable)	$450
Initial license — sole owner	$200

Keeping the License Current

Renewal of the California Class C-27 — Landscaping Contractor comes due every 2 years. As cited, the renewal fee stands at $450. Active sole-owner licenses renew every two years for $450. Non-sole-owner licenses renew for $700. Inactive licenses renew for $300 (sole) or $500 (non-sole). Renewal notices are mailed approximately 60 days before expiration. CSLB does not impose a continuing-education requirement, although the contractor is responsible for staying current on changes to the California Building Standards Code and the trade-specific code that governs the license classification.

Reciprocity and License Transfer

The NASCLA Accredited Examination is not accepted by California for this classification.

Reciprocal State	Accepted Exam	Conditions
Arizona	Trade exam waived	CSLB reciprocity for active five-year C-27 holders matching an equivalent AZ ROC classification.
Nevada	Trade exam waived	Bilateral CSLB–NSCB reciprocity for active five-year C-27 licensees.
Utah	Trade exam waived	Reciprocity for S330 Landscape Contractor under CSLB–DOPL agreement.

California only waives the trade exam; Law & Business must still be passed.

Frequent Application Errors

Working from the cited board instructions, here are the snags most likely to trip up a California Landscaping filing.

Vague experience verification

A common reason CSLB returns the Certification of Work Experience is generic phrasing such as "helped out on jobsites" or "assisted the foreman". The verifier must use specific journeyman-level trade terminology, and the dates must match the applicant's W-2 record.

Bond and license number mismatch

The business name and license number on the contractor's bond must correspond exactly to the CSLB record. Even a missing "Inc." or a transposed digit will cause CSLB to reject the bond and delay issuance until a corrected rider is filed by the surety.

Missing the asbestos open-book exam

Many applicants assume the bond and fee letter only requires the bond and the initial fee. The completed Asbestos Open-Book Examination is required in the same envelope. Forgetting it sends the application back to the bottom of the Issuance Unit queue.

Workers' compensation exemption errors

Sole owners with no employees may file an exemption, but certain classifications (notably C-39 Roofing) cannot. Filing an exemption when not eligible voids the entire issuance package.

Letting the application time out

Once CSLB accepts the application, the applicant has 18 months to pass both examinations and submit all post-exam documentation. Applicants who pause to re-take the exam multiple times frequently let the clock expire and have to refile from scratch (forfeiting the $450 application fee).

Applying pesticides without DPR QAL

CSLB C-27 alone does not authorize commercial pesticide use. DPR enforces separately with fines.

Working without the bond on file

License is suspended until the bond is posted and accepted by CSLB.

Other California Trade Licenses

If the Landscaping license is not the right fit, the following published California trade guides are also covered by CLR:

Questions Applicants Ask

Do I need a C-27 for simple lawn mowing?

No. Gardening and routine maintenance under $500 per job does not require a CSLB license. Installation, grading, irrigation, and hardscape do.

Does the C-27 cover pesticide application?

No. Any commercial pesticide application requires a California DPR Qualified Applicator License (QAL) or Certificate (QAC) in addition to the C-27.

How much is the bond?

$25,000 contractor bond posted with CSLB. A separate $25,000 bond of qualifying individual is required if the RMO/RME is not an owner.

Can I substitute education for experience?

Up to three years may be credited for accredited horticulture or landscape architecture coursework and approved apprenticeship completion. One year of hands-on experience is always required.

Does the C-27 cover tree work?

Planting and pruning incidental to a landscape project yes. Standalone tree removal or arborist work is better served by the D-49 Tree Service classification.
