What does “S330 license” mean and why does it matter for a landscaping company?

The S330 license is Utah’s official classification for landscape contractors. It’s issued by the Department of Professional Licensing and ensures that companies performing landscaping work have met state requirements for training, insurance, and accountability. Without this license, a contractor is not legally allowed to install irrigation systems, hardscaping, or major planting projects. For homeowners in Salt Lake and Davis Counties, checking that your contractor has an active S330 license protects you in two ways: it confirms they’re operating legally, and it gives you recourse if the job goes wrong. Licensed contractors can be held accountable through the state, while unlicensed operators leave you with little protection. Verifying an S330 license is simple — search the DOPL database using the company’s name or license number. If a landscaper won’t provide that number, consider it a red flag. This step takes minutes but can save thousands in mistakes and liability.
