The City Arborist Program administers the City of Austin's Tree Ordinance and issues permits to remove or impact regulated trees. On private property, the City regulates three classifications of trees: 8- to 18-inch diameter, Protected Trees, and Heritage Trees. Tree preservation requirements are detailed in Section 3 of the Environmental Criteria Manual.

How do I measure a tree?

Visit the Trees on Residential Property or Trees on Commercial and Multifamily Property webpage to learn about how to measure a tree. 

My neighbor’s tree limbs are growing over my property line. Can I prune them?

Legally, this is a civil matter between the property owners. Typically, landowners may remove vegetation that crosses their property line, or the air space directly above it. However, we strongly encourage neighbors to discuss these issues and agree on a plan before any action is taken. We also encourage using ideal pruning techniques. NOTE: If the tree is regulated (19 inches or more in diameter), no more than 25% of the canopy may be removed without a permit.

Who can help me? (Tree contacts across the City)

Stewarding our community’s tree resources is a team effort, and many departments across the City regulate and provide services related to trees. Visit our Who Can Help Me? page to find the right contact to address your question or concern.

How do I apply for a tree permit?

When the development of a residential property contains a regulated tree, the tree review will occur simultaneously with the building plan review. The tree permit will accompany the residential building permit.

When a regulated tree is not development-related but impacted by utility issues, disease or other conditions, a Tree Ordinance Review Application (TORA) is required.

What jurisdictions are subject to the Tree Preservation Ordinance?

The City of Austin’s Tree Preservation Ordinance applies in Austin's Full and Limited Purpose jurisdictions. The ordinance does not apply in the Extra-territorial Jurisdiction (ETJ). You can use the Property Profile tool to look up a property's zoning by address.

What is a tree survey tag?

A tree survey tag (generally an aluminum circular or rectangular label attached to the tree trunk) assigns a specific identification number to a tree for a site plan or survey. It does not mean the tree is marked to be saved or removed. 

Will the City prune or remove my tree?

The property owner is responsible for tree removal or required maintenance unless the tree is located on public property.

Something is wrong with my trees. Can someone come out and look at them?

While we are happy to answer basic questions over the phone or via email, residents should hire an International Society of Arboriculture (ISA) certified arborist for tree problems on private property. The City of Austin does not provide tree consulting for residents.

The Find an Arborist tool from Trees Are Good or the American Society of Consulting Arborists may help you find a certified arborist in your area.
