Gilbert, AZ Landscaping Rules: Tree Removal & Heritage Trees (2026)

4, requires that all approved trees meet a minimum size table the Town applies across required landscape areas townwide. Deciduous and non-deciduous shade trees must measure at least six feet in height, which the Code notes is typically achieved with a 24-inch box specimen. Palm trees carry a lower standard of five feet of height at planting. 75-inch minimum is averaged across the two largest trunks. Beyond size, subsection 1 layers on a sight-visibility rule: any tree planted within the sight distance triangle at a controlled or uncontrolled intersection must also meet the trunk height and visibility requirements in the Town's separate Engineering and Construction Standards, so a tree that meets the minimum planting-size table can still be rejected at an intersection corner if its trunk or canopy blocks sightlines.

These size floors apply wherever the Code requires landscaping, parking lots, side and rear buffers, and street frontages, and are checked by Planning & Development Services against the approved landscape plan before a project receives Design Review sign-off, and again during the final landscape inspection tied to a Certificate of Occupancy.
