Climate & Hardiness in SAN ANSELMO
SAN ANSELMO sits in USDA Plant Hardiness Zone 9b, with winter minimum temperatures of 25–30°F. This means a true dormant season — lawns and most perennials slow significantly from December through February. Contractors experienced in Zone 9b know to schedule irrigation shutdown before first frost, design planting schemes around the zone's long dry summers, and recommend drought-tolerant species that handle both the heat and the occasional cold snap. Ask any contractor you hire whether their plant selections are rated for Zone 9b minimums.

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 — 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 SAN ANSELMO winterize irrigation systems?
Yes. SAN ANSELMO 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.
