Yes. Workers Compensation is required. That protects you from an employee injury claim on your property.
There are two specific class codes that are used by the National Council on Compensation Insurance (NCCI) for workers who are in the landscaping industry. These two classification codes that are important to know are 0042 and 9102. There official descriptions from NCCI are:
Class Code 0042 – Applies to employees primarily engaged in planning, clearing, grading, laying of sod, seeding, and planting necessary for landscape installation operations. Planting of trees, shrubs, and flowers are classified to this code along with general gardening activities.
Class Code 9102 – Applies to employees that perform maintenance of lawns, grounds, and gardens. “The maintenance may involve lawn mowing, raking, application of liquid or granular fertilizer, spraying and trimming of shrubs or small trees from the ground, and thatching or aerating. If any one or all of the above operations are performed by a lawn maintenance risk classified to Code 9102, then minor and incidental landscaping operations performed by the same risk, such as the replacement of dead shrubs, the planting of a few flowers, and the placing of rock or brick as edging designs are included under Code 9102. This minor landscaping operation is distinguished from work performed by an insured at a job or location where the primary work at the job or location is landscaping. Since lawn spraying is a maintenance operation, a risk engaged exclusively in work of this nature is classified to Code 9102.”
