Anaheim, CA Landscaping Rules: Tree Trimming (2026)

AMC Section 18.46.090 requires all pruning or trimming of required trees and specimen trees to comply with standards adopted by the International Society of Arboriculture (ISA) and be consistent with AMC Chapter 13.12 (Street Trees). Tree topping is prohibited as it damages tree health and structure. Street tree maintenance is coordinated by the city's Public Works Department, and residents should not trim street trees without authorization. AMC 18.46.030 establishes tree requirements for landscaping plans. Trees along parkways are maintained by the city on a regular cycle. Property owners are responsible for maintaining trees on private property. Dead, dying, or hazardous trees must be addressed to prevent safety hazards. The city maintains an Official Tree Species List under AMC 13.12.030 for approved street tree varieties.
