Frequently Asked Questions
How do I verify a landscaping contractor's license in California?
Every contractor on this page links to its official CSLB license-detail record. Search the license number at cslb.ca.gov to confirm the license is current, the classification is C-27 (Landscaping), and the status is CLEAR before you hire.
What is the difference between a C-27 licensed contractor and an unlicensed landscaper?
A C-27 license means the contractor passed California's trade and law exams, posted a contractor bond, and is accountable to the CSLB. Unlicensed operators carry none of those protections โ you have little recourse if work is defective or someone is injured on your property.
Why does workers' compensation insurance matter when hiring a landscaper?
If a contractor employs a crew, active workers' comp insurance means you are not liable for on-site injuries. A contractor without it can legally work alone, but you take on real risk the moment an uninsured crew sets foot on your property.
Do landscapers in Contra Costa County winterize irrigation systems?
Yes. Contra Costa County sees a real frost season, so experienced contractors schedule irrigation shutdown before first frost and choose cold-hardy plant material rated for the local winter lows.
