Cal-Nev-Ari Landscaping Rules: Tree Trimming Rules (2026)

Clark County Code Title 14 Section 14.15 requires abutting property owners to keep trees and shrubs trimmed back from the public right-of-way so that sidewalks have at least 8 feet of vertical clearance and streets have at least 14 feet. Overhanging vegetation that blocks sidewalks, streetlights, or stop signs is abatable under Title 14.55 nuisance rules. Clark County Public Works manages trees in the street right-of-way directly on arterials and collectors; on local streets the burden is typically on the abutting owner. For private tree disputes between neighbors, Nevada follows the Massachusetts rule: a neighbor may trim branches and roots back to the property line at their own expense without notice, but may not enter the neighbor yard or damage tree health. A neighbor who kills a healthy tree by excessive cutting can be liable for treble damages under NRS 40.090 (willful trespass timber statute). Fruit and nuts falling into a neighbor yard belong to the tree owner in Nevada unless naturally fallen without inducement. HOAs in Summerlin, Anthem, and Mountains Edge often maintain master tree lists and require approval before removal. Mesquite, palo verde, and desert willow are protected drought species in some community plans; removal without permit can trigger replacement requirements.
