What a Landscaping contractor (C-27) license covers

Landscaping (C-27) covers building and installing landscape systems: grading for planting, irrigation, low-voltage lighting, walkways, patios, decks and fences that are part of a landscape job.

Note: Routine gardening and lawn mowing generally isn't CSLB-licensed work; installing irrigation, hardscape or structures is. Under California's minor-work exemption, jobs under $1,000 (labor and materials combined) that need no building permit generally don't require a CSLB license.
