A C-27 Landscaping license is what California requires before you may contract to build the landscape itself — the grading, the hardscape, the drainage and irrigation, the planting. Earning one means putting four years of journey-level work on paper, sending CSLB a $450 application, clearing a Department of Justice and FBI background check, passing the Law and Business exam and the C-27 trade exam at PSI, and filing a $25,000 bond. This guide walks that path in order using only figures the board and the statutes actually publish, and it flags the two places where landscaping is handled differently from every other trade: the horticulture-degree credit, and the Spanish-language exam rule.
C-27 is the Landscaping classification, and the definition CSLB works from — California Code of Regulations, title 16, division 8, article 3 — describes an outcome rather than a product list. A landscape contractor constructs, maintains, repairs, installs or subcontracts the development of landscape systems and facilities for public and private gardens and other areas designed to improve the grounds around a structure or a plot of land aesthetically, architecturally, horticulturally or functionally, and grades the ground for that work. Drainage, irrigation, planting, hardscape and low-voltage landscape lighting all sit inside that one sentence.
Business and Professions Code section 7027.5 then attaches four specific powers. A landscape contractor may design the systems that same contractor will build and supervise, and may hold the prime contract on a landscape project containing a swimming pool, spa or hot tub — the pool work itself going to a single licensed C-53 Swimming Pool contractor, unless the landscape contractor holds C-53 too — an outdoor cooking center, an outdoor fireplace not attached to a dwelling, or a rainwater capture system serving landscape irrigation. Whatever falls outside the C-27 scope on those jobs goes to someone holding the right specialty classification or a B General Building license: prime-contracting a whole backyard does not quietly widen what you may self-perform.
The small-job exemption is Business and Professions Code section 7048, rewritten by AB 1170 with effect from January 1, 2026. Three conditions have to hold together: everything the customer pays for — labor, materials, the lot — comes to under $1,000; the work is genuinely casual, minor or inconsequential; and no building permit is required. It is then withdrawn from anyone advertising as a contractor and from anyone employing another person to do or help with the work, and carving a bigger job into sub-$1,000 contracts does not rescue it. Some CSLB print material still quotes the older $500 threshold; the amended statute governs.
Two rules bite harder here than in other trades. Section 7026.1 makes tree removal, pruning, stump removal and tree or limb cabling and guying contracting in their own right, sparing only a nurseryperson pruning or guying incidentally in routine work, and a gardener incidentally pruning trees under 15 feet tall after planting. Section 7049 separately keeps the chapter off construction incidental to farming, agriculture, viticulture and horticulture. So mowing and ordinary garden care stay outside; the moment a crew sets a valve manifold, cuts in a drain line or takes down a mature tree, it is contracting.
Every license stands on a qualifier, and that person needs four years or more of experience in the classification being applied for, gained inside the past 10 years, at journey level or higher — journeyperson, foreperson or supervising employee, contractor, or owner-builder. CSLB's journeyperson is a fully qualified worker who can run the trade unsupervised, or someone who finished an apprenticeship — expressly not a trainee, helper or laborer. Claims go on the Certification of Work Experience form, certified by someone with firsthand knowledge of the work. A randomly drawn share of applications is then pulled for documentary review, and the license waits until that review closes, whether or not both exams are already passed.
Three of the four years may come from training, apprenticeship or education, and Landscaping is one of only two classifications CSLB's credit table names individually. A four-year degree from an accredited college or university in horticulture, landscape horticulture or landscape architecture earns the full three-year maximum on a C-27 application; so does a certificate of completion of apprenticeship, or a four-year degree in construction technology or management. One year of practical experience stays mandatory, transcripts must arrive sealed and straight from the institution, and a foreign degree first goes through an accredited United States evaluation service.
Section 7068 decides who may qualify a license, and the answer follows the business structure. Sole owners qualify themselves; partnerships through a general partner; corporations through a responsible managing officer (RMO); LLCs through an RMO, a responsible managing manager or a responsible managing member. Any of them may instead use a responsible managing employee (RME) — permanently employed and genuinely working in the trade, which CSLB pins at 32 hours a week or four-fifths of the hours the business is open, whichever is smaller. Qualifying through an RME, or an RMO holding under 10 percent of the voting stock or equity, adds a $25,000 bond of qualifying individual. LLC applicants also carry a $100,000 LLC/worker bond and liability insurance from $1 million aggregate.
The Application for Original Contractor License reaches CSLB with a $450 processing fee covering one classification. The fee buys processing, not approval: rejection does not refund it, and a returned application has 90 days to come back corrected before it voids for good. Acceptance brings a Notice to Schedule an Examination. Every first-time applicant listed — owners, officers, partners, members, managers, RMEs — also submits fingerprints, which CSLB runs against Department of Justice and FBI records; nothing issues until both come back.
Licensure runs through the Law and Business exam and the C-27 trade exam, both scheduled and paid directly with PSI, CSLB's testing vendor, each allowing three and a half hours. Law and Business is administered in 18 other states besides California; the trade exam only in California and Oregon. Fail either and a retake opens after 21 calendar days, provided you are still inside the 18-month window that starts the day your application is accepted. Run that clock out and the application is void.
Language is where landscaping parts company with most trades. C-27 is one of ten exams CSLB publishes in an official Spanish version, beside Law and Business, B, C-8, C-9, C-15, C-33, C-36, C-39 and C-54. The consequence catches people out: on those ten, a candidate who requests a translator is required to sit the Spanish version instead. The approved-translator arrangement covers trade exams with no Spanish edition, so a Russian- or Armenian-speaking applicant here is choosing between the English paper and the Spanish one.
Passing produces a Bond and Fee letter, not a license; it itemises what your application still owes.
An active license needs a $25,000 contractor's bond on file, or a cashier's check for the same sum (section 7071.6). That is face value, not cost: a surety prices the premium largely on your credit, so no honest quote exists before you apply for one. Sole owners then pay $200 as the initial license fee, every other entity type $350, separately from the $450.
C-27 sits outside the five classifications — C-8, C-20, C-22, C-39 and C-61/D-49 — required to carry workers' compensation whether or not they employ anyone. A landscaping licensee with no employees and no RME qualifier may therefore file an Exemption from Workers' Compensation rather than buy a policy. Two things end it. Adding D-49 Tree Service to the license puts you on the list at once, which is worth pricing before you expand into tree work. And the version of section 7125 that becomes operative on January 1, 2028 removes the no-employee exemption for everyone but no-employee joint ventures, so treat coverage as a dated cost rather than a permanent escape.
After the license exams the qualifier sits CSLB's open-book asbestos examination and returns the signed verification form with the bond and fee paperwork; without it the license cannot be processed. Passing confers no authority to do asbestos work — that is a separate certification. You can work through the asbestos open-book material here at no cost.
CSLB publishes the $450 application fee, the initial license fee of $200 or $350, and $32 to the Department of Justice plus $17 to the FBI, on top of a rolling fee each live scan site sets for itself. It does not publish the PSI exam fee, which you pay PSI at booking, and cannot publish bond or workers' compensation premiums, which private companies price. It does say plainly that no school or application-preparation service is affiliated with it, and that its study guides download free.
No turnaround is promised, but CSLB updates a Processing Times page weekly showing which application dates each unit is working through, letting you locate yourself in the queue. Delays cluster predictably: a returned application restarts its own 90-day clock, hard fingerprint cards mailed from out of state take longer than a California live scan, and an application drawn for experience review sits until that review finishes.
Active licenses renew every two years, inactive ones every four. Renewing an active license on time costs a sole owner $450 and everyone else $700; let it go delinquent and those become $675 and $1,050. CSLB mails the form about 60 days ahead and you can order one if nothing has arrived 45 days out, but the deadline binds either way; since 2021 the registrar must reinstate an expired license retroactively when a complete renewal and the fees land within 90 days of expiration. Between renewals the duties are continuous: bond in force, a qualifier on the license, workers' compensation or a current exemption filed, and changes of address, name and personnel reported. Switching entity is not a renewal but a new license with a new number.
Both exams reward reading the rule over recognising an answer. Drill the C-27 Landscaping practice test alongside the CSLB Law and Business practice test, and treat every wrong answer as a reason to reread its explanation.
