California’s heterogeneous climate and reverberating real estate market make landscaping a growing industry. From drought-resistant gardens to lush lawns, skilled landscapers are in high demand.
However, starting a landscaping business in California involves more than horticultural knowledge. Business owners must comply with specific licensing and regulatory requirements to operate legally.
Understanding the necessary certifications, insurance, and registrations is critical to building a successful and lawful landscaping business in California.
Licensing Requirements
a. Landscaping Business
i. C-27 Landscape Contractor License
To legally manage landscaping work valued at $500 or more (labor and materials), you must obtain a C-27 Landscape Contractor License from the Contractors State License Board (CSLB). This license allows you to work smoothly without any obstacles, develop landscapes, install irrigation systems, plant trees and shrubs, and build features like retaining walls or walkways.

ii. License Classification Based on Scope of Work
The state of California does not classify licenses based on yard size, your scope of work determines the type of license you need.
For instance:
Installing a sprinkler system: C-27.
Building patios or masonry: You may need additional specialty licenses like C-29 (Masonry) or C-8 (Concrete).
iii. Subcontractors
Workers who work under a licensed landscape contractor are not required to hold a license themselves, but the primary contractor assumes full legal and financial responsibility.
