Redlands, CA Landscaping Rules: Tree Trimming (2026)

Redlands has one of the more protective street-tree programs in the Inland Empire, reflecting its historic tree-lined character. Trimming, planting, or removing any tree within a city easement or public place is governed by Municipal Code Chapter 12.52, 'Trees and Tree Protection Along Streets and in Public Places.' A Public Tree Encroachment Permit is required for any such work. Per Municipal Code Section 12.52.140, work on public trees must comply with the standards established by the International Society of Arboriculture (ISA), and permits are required for work on public trees unless specifically exempt under the chapter. The city waives the permit fees associated with voluntary trimming, planting, or removal of public trees when residents hire certified contractors, subject to approval by the Facilities and Community Services Department. Applicants also receive guidelines for protecting nesting birds while trimming. The city maintains roughly 42,700 street trees in easement areas (out of about 56,500 total tree sites), so the easement strip between sidewalk and curb in front of most homes typically holds a city-regulated tree. Heritage and landmark trees, and historic groves of a particular species in a specific area (for example, the palm trees along Cajon Street), receive added protection. Trimming a tree entirely on private property that does not affect public property, safety, or public trees is generally not subject to this permit. Permit requests go to the Facilities and Community Services Department, 35 Cajon Street, Suite 222.
