Hiring a Landscaper in San Francisco, California
California requires landscapers to hold a Landscaping Contractor (C-27) license issued by the Contractors State License Board (CSLB). Before hiring a landscaper, you can verify their license status online through CSLB's license-check tool. You can search by the contractor's license number (found on their pocket license), business name, or the owner's name. The search will disclose any complaints filed against the contractor.
Many landscaping projects require a building permit from your local building department. California Building Standards Code requires permits for most construction, improvement, and alteration work. Because code requirements vary between cities and counties, contact your local building department to confirm what permits you need for your specific project.
When hiring a landscaper, ask whether your project requires a permit and confirm the contractor will handle permitting if needed. Request that the contractor provide their license number and verify it before signing a contract. Get the terms of the work in writing, including scope, timeline, and payment schedule.
