How Phoenix Handles Tree Protection: A Practical Guide

Phoenix maintains 251 local ordinances across all categories, and 4 of those deal specifically with tree protection. Here is a breakdown of what the city actually requires, what is prohibited, and where Phoenix falls on the strict-to-permissive spectrum compared to other cities.

Tree Removal Permits

Phoenix requires permits for removing protected native trees and trees over 6 inches in diameter, per City Code Chapter 34 and the Tree and Shade Ordinance. Street trees on public property or rights-of-way always require city approval. Arizona also requires 20-60 day notification to the Department of Agriculture before destroying protected native plants.

Key details: City Code: Chapter 34, Tree and Shade Ordinance. Permit Threshold: Trees over 6 inches in diameter. State Notice: 20-60 days to AZ Dept of Agriculture. Residential Exemption: ≤10 acres with prior construction. Contact: Planning & Development Department.

Unauthorized removal: $500 to $10,000 per tree depending on size and species. Replacement planting required at 2:1 or 3:1 ratio.

Heritage & Protected Trees

Phoenix protects historic and heritage trees under its Tree and Shade Ordinance and City Code Chapter 34. Protected species include native desert trees such as palo verde, mesquite, and ironwood. The city may designate additional trees as heritage trees. Unauthorized removal can result in fines of $500-$5,000 and mandatory replanting.

Key details: Protected Species: Palo verde, mesquite, ironwood, others. Code: Chapter 34, Tree and Shade Ordinance. Fines: $500-$5,000 for unauthorized removal. Mitigation: Replanting or replacement may be required. Exemption: Dead/diseased trees certified by arborist.

Unauthorized removal of heritage tree: $2,000 to $25,000. Damage during construction: $1,000 to $10,000 plus remediation costs.

Tree Replacement Requirements

Phoenix's Tree and Shade Master Plan requires replanting or replacement of removed trees in many cases. Residents may need to select appropriate replacement trees from approved species lists (AMA-3550), pay a fee, or plant multiple trees depending on the size of the removed tree. The goal is maintaining the urban tree canopy.

Key details: Plan: Tree and Shade Master Plan. Replacement Species: From AZ Dept of Water Resources AMA-3550 list. Ratio: May require multiple replacements per removed tree. Fee Option: Payment in lieu of replanting may be available. Care Required: Proper care of replacement trees required.

Failure to replace: $250 to $1,000 per tree plus required planting. Fee-in-lieu non-payment: lien on property.

Tree Ordinances

Phoenix has a Tree and Shade Master Plan and enforces tree preservation requirements through its zoning ordinance and development standards. Protected native trees, including Palo Verde, Ironwood, and Mesquite species, are regulated under the city's Native Plant Ordinance (Chapter 6, Section 6-8). Developers must preserve or relocate protected native trees on development sites.

Key details: Protected Species: Palo Verde, Ironwood, Saguaro, Mesquite. Governing Code: Chapter 6, Section 6-8 (Native Plant Ordinance). Canopy Goal: 25% coverage (Tree and Shade Master Plan). First Offense Fine: Up to $2,500 per plant.

Destroying protected native plants without a permit can result in fines of up to $2,500 per plant for a first offense. Repeat offenses may result in higher fines and criminal misdemeanor charges. Developers who fail to obtain native plant permits face project delays and additional mitigation requirements.

The Bottom Line

Phoenix's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Phoenix is broadly strict or permissive.

These rules come from Phoenix's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
