Duties of a Landscaping Contractor

The duties of landscaping contractors tend to vary on the needs of a client.

Typically they engage in a wide range of activities including:

  • Planting flowers, trees, and shrubs
  • Installing retaining walls, sprinkler systems, and low-voltage lighting systems
  • Soil preparation and testing
  • Constructing decks, fountains, and planters
  • Lawn repair and maintenance 
  • Bidding, estimating, creating invoices, accounting, and book-keeping
  • Maintaining a safe job site

Landscaping services tend to deal directly with the consumer public.

The CSLB considers the C-27 license to be very important in order to protect the interests of:

  • Homeowners, Schools, and Churches 
  • Small businesses and Government Agencies

All of whom employ the services of a landscaping contractor. 

What is a Landscaping Subcontractor?

Typically landscapers work directly with homeowners or clients.

However, a landscaping business may also be subcontracted by a General Contractor.

Landscaping services may have been offered as part of a bid by a General Contractor.

Therefore, an individual or company holding the C-27 license would be in charge of executing the landscaping portion of the construction process.

California Landscape License Look Up

The CSLB allows the consumer public to check any license number at any time.

To check the license number of a landscape contractor you can visit the Contractors State License Board official license look-up page. 

The consumer public is encouraged to do extensive research before hiring any contractor.

Utilize the resources available to you. 

For landscape contractors, your reputation and license number are very important. Do everything you can to protect this number. 

How to get the Landscaping License

To get the C-27 License you have to  meet the following requirements:

  • Be at least 18 years of age
  • Have a valid driver's license or USA Issued Identification
  • Have a Social Security or ITIN #
  • Not currently on probation or parole

You must also have:

  • 4 years of journeyman-level experience
  • A Certifier to sign off on your experience
  • A way to prove your experience if the state asks for documentation

What is Journey Level Experience?

Journeyman-level experience means that you have worked unsupervised full-time for an electrical company, or contractor that holds the C-27 License.

  • A journeyman landscaper can perform all of the duties associated with his or her trade.

The CSLB will want to see four full-time years over the last ten years.

The years do not need to be consecutive, but they do need to be four years in total. 

Signature of a Certifier

The following people can sign off on your experience:

  • Licensed General Contractor
  • C-27 License Holder
  • Fellow Employee (within the last 10 years)
  • Former Supervisor (within the last 10 years)
  • Business Associate
  • Fellow Journeyman
  • Union Representative

Proving Your Work Experience for the C-27 License

You must be prepared to submit documentation supporting the experience you claim to have.

The Contractors State License Board gives you a few ways that you can prove your experience.

  • Tax Returns
  • Check Stubs
  • Contracts
  • Material Order Invoices or Receipts

The CSLB  receives thousands of applications per month so there is a good chance they won’t document your experience.

However, if you are one of the applicants that get reviewed you will need to be ready to submit something. 

The CSLB does not accept pictures of projects.

Filling out the C-27  License Application

This person you choose to sign for you will also need to provide a brief but detailed description of your knowledge and skill set.

How this description is written will be critical to whether or not your application is accepted.

For example:

“Jorge is a nice guy he has trimmed grass…”  is not going to be accepted by the CSLB

The CSLB will want to see something more like:

Jorge has prepared and tested soil, installed lawns, transplanted trees, maintained gardens, installed drainage systems, etc.

Application Processing, Fees, and Criminal History

The time it takes to get your application processed and assigned a test date fluctuates throughout the year.

Typically you can expect:

  • 6-8 Week Application Processing Time
  • 3-4 Week wait for an Exam date

I have seen some situations where applicants got their test date sooner and somewhere they got their test date much later.

The most common reasons your application would get held up are:

  1. Time of year (processing time slows down during the holidays) 
  2. Criminal History 
  3. Proving Experience
  4. Mistakes on your application 

Application Costs for the C-27 License

The Current CSLB fees are:

Having a criminal record in no way stops you from getting a C-27 License.

The key is, to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.

BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting.

See the CSLB's verbiage below:

Just because you have been convicted of a crime does not automatically mean
your application will be denied. CSLB's Criminal Background Unit (CBU) reviews
all criminal convictions to determine if the crime is substantially related to
the duties, qualifications, and/or functions of a contractor. Since no two
conviction records are the same, they are reviewed on a case-by-case basis. The
criteria used by CSLB include whether the crime shows the present or potential
unfitness of an applicant or licensee to perform the functions authorized by
the license in a manner consistent with the public health, safety, or welfare.
In addition, CSLB reviews and considers any evidence of rehabilitation
submitted by the applicant or licensee. Please see the above link to the
California Code of Regulations sections 868 and 869 for more specific
information on the criteria for determining substantial relationship and

Be honest when applying to the CSLB

The CSLB handles criminal records on a case-by-case basis.

Remember, their responsibility is to protect the public.

In my experience, they are primarily concerned with criminal charges associated with:

  • Fraud
  • Embezzlement 
  • Forgery

In the state of California, you are required to divulge any criminal charges when applying for any state license even if they have been expunged.

You will need to be prepared to submit anything they ask for regarding your criminal history.

Landscaping Contractors License Practice tests, study guides, and schools

  • The questions you will see on the exam may use outdated terms
  • Processes may be completely different from how things are done on the job site
  • You will see questions about things you may have never done before
  • Questions will be presented to you as if you are running a large-scale construction business with several employees and jobs happening all at once. 
  • Know all aspects of your trade

I have helped all types of construction professionals from various backgrounds and experience levels get licenses, and most are startled by how different the subject matter on the state exam is from their years of first-hand experience. 

Be as prepared as you possibly can.

Studying just 10 minutes a day consistently can dramatically increase your chances of passing the test on your first try.

Focus on and study ONLY the information that you need to pass the C-27 License exam. 

Landscaping Apprenticeships

Your journey begins here!

Highly skilled landscapers are always in demand. Whether you are completely new or have some experience already, there are resources available to you.  

Generally, someone looking to become a landscaping contractor would want to look into an apprenticeship or certification program.

Blueprint Reading Course

It is critical for the landscaping contractors to be able to follow specific designs and blueprints to identify exterior elevations correctly, site works, and irrigation systems as well as other plans that affect the landscape work.

As their duties are limited to the exterior, identifying plot plans is a very important skill.

Blueprint Reading Skills are also critical to pass the General Contractor exam.

EPA Certification

Understanding how to safely contain lead-based paint when altering structures built before 1978 is required by the Environmental Protection Agency.

The most profitable landscaping contractors are the ones that position themselves as the experts and are the most knowledgeable and helpful to their clients.
