Lewisville, TX Landscaping Rules: Tree Trimming (2026)

Lewisville Code of Ordinances requires property owners to maintain trees on private property so branches do not obstruct public sidewalks, streets, or sight lines at intersections. Minimum clearance over sidewalks is typically 8 feet and over streets is 14 feet. The city Public Works department handles trimming of trees in public rights-of-way and along city-maintained medians. Property owners are responsible for all trimming on private property including limbs that extend over neighboring properties. Dead, diseased, or hazardous trees that pose a risk to public safety may be ordered removed by Code Compliance. The city arborist or designated official may assess tree health when complaints are filed. Oak wilt is a concern in the North Texas region; the Texas A&M Forest Service recommends avoiding pruning oaks from February through June to prevent spread. Lewisville does not require a permit for routine trimming of trees on private property, but tree removal may be subject to the tree preservation ordinance depending on the size and species.
