Anyone performing landscaping services for compensation must be registered as a contractor with the Washington State Department of Labor & Industries (L&I). This ensures that landscapers operate legally and maintain insurance and bonding to protect both workers and clients. Certain landscaping tasks, such as installing irrigation systems or constructing retaining walls, may require additional specialty contractor licenses. Furthermore, if the landscaping work involves the use of pesticides or herbicides, the applicator must possess appropriate certifications from the Washington State Department of Agriculture. Work hours, noise ordinances, and other local regulations may also affect when and how landscapers can perform their duties in different municipalities across Washington. For anyone planning a landscaping project—whether for residential or commercial properties—compliance with state and local laws is essential.Tips 1:As a designer myself, I always recommend that, beyond simply hiring a licensed landscaper, you take a holistic approach by considering how your landscaping integrates with your overall home design.
