Hiring a Landscaping Contractor in Los Angeles, California
Landscaping contractors in California must hold a state license. The Contractors State License Board (CSLB) classifies landscaping work under the C-27 Landscaping Contractor license type. Before hiring, verify the contractor's license number and status on the CSLB online license-check tool at cslb.ca.gov. You can search by license number (8 digits) or business name. The license check will show the current status and any complaint history.
Some landscaping projects require a building permit from your local building department. Permit requirements vary by city and county; the scope and type of work—such as hardscaping, irrigation installation, or grading—determine whether a permit is needed. Contact the Los Angeles Department of Building and Safety (LADBS) or your city's building department to find out what applies to your specific project before work begins.
When choosing a contractor, ask to see their pocket license, confirm their C-27 classification, and request references. Discuss the scope of work in writing, clarify whether your project needs permits, and verify that the contractor will handle or coordinate any required permit applications. Get a detailed contract that outlines the work, timeline, and payment terms.
