Arlington, TX Landscaping Rules: Tree Trimming (2026)

The City of Arlington requires property owners to keep trees and shrubs on their property trimmed so that branches do not obstruct public rights-of-way. Overhanging branches must be maintained at a minimum clearance of 8 feet above sidewalks and 14 feet above streets and alleys. Branches must not block traffic signs, street lights, or sightlines at intersections. If a property owner does not trim branches obstructing the right-of-way after notice, the city may perform the work and bill the owner. Routine pruning of trees on private residential property does not require a permit. However, trees on commercial development sites, along thoroughfares, and in certain zoning districts are covered by the city landscape and tree preservation ordinance, which regulates removal and significant pruning of protected trees. Property owners are encouraged to avoid topping trees, which damages long-term health, and to follow ANSI A300 pruning standards. Oak trees in particular should be pruned in the dormant season (roughly November through January) to minimize the risk of oak wilt transmission, which is a serious concern across North Texas.
