How Ann Arbor Handles Tree Protection: A Practical Guide

Ann Arbor maintains 111 local ordinances across all categories, and 3 of those deal specifically with tree protection. Here is a breakdown of what the city actually requires, what is prohibited, and where Ann Arbor falls on the strict-to-permissive spectrum compared to other cities.

Tree Removal Permits

Ann Arbor requires permits to remove trees above a certain size on private property. Protected species and street trees have additional restrictions.

Key details: Permit Threshold: 6 to 12 inch DBH typical. Street Trees: City-managed, no removal. Hazardous Trees: Expedited permit available. Replacement: 2:1 or 3:1 ratio.

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

Ann Arbor designates heritage or landmark trees based on size, age, or species. Removal or damage to heritage trees carries significant penalties.

Key details: Designation: Size, species, or historical. Typical Size: 24+ inch trunk diameter. Removal: Council approval required. Topic: Heritage Trees.

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

This is one of the stricter rules in Ann Arbor's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Tree Replacement Requirements

Ann Arbor requires replacement planting when permitted trees are removed. Replacement ratios and species specifications ensure canopy preservation.

Key details: Ratio: 1:1 to 3:1 replacement. Minimum Size: 1.5 to 2 inch caliper. Species: Approved native/adapted list. Alternative: Fee-in-lieu to tree fund.

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

The Bottom Line

Ann Arbor'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 Ann Arbor is broadly strict or permissive.

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