Do You Need a City Permit to Remove a Tree in Austin? A Comprehensive Guide

Austin loves its urban forest. The city’s tree canopy provides shade, reduces the urban heat island effect, and significantly boosts property values. To protect this vital resource, the City of Austin has implemented some of the strictest tree protection ordinances in Texas.

If you are planning to cut down a tree on your property, assuming you can just fire up a chainsaw is a mistake that could cost you thousands of dollars in fines. Whether you are dealing with storm damage, a dead tree, or clearing space for a new addition, you must understand the rules before you make a cut.

Understanding DBH: The Golden Rule of Tree Measurement

Everything in Austin's tree ordinance revolves around a measurement called DBH (Diameter at Breast Height). To calculate DBH, measure the circumference of the tree trunk at exactly 4.5 feet above the ground, and then divide that number by pi (3.14).

If a tree has multiple trunks splitting below 4.5 feet, the city uses a specific formula to calculate the total diameter. Based on this measurement, trees in Austin fall into three main regulatory categories:

1. Unregulated Trees (Under 19 inches DBH)

If a tree measures less than 19 inches in diameter, it is generally considered unregulated. You do not need a city permit to remove it, assuming it is entirely on your private property and not in a right-of-way or protected environmental easement.

2. "Protected" Trees (19 to 23.9 inches DBH)

Trees with a DBH between 19 inches and 23.9 inches are legally classified as "Protected Trees." To remove one of these trees, you must submit a Tree Ordinance Review Application (TORA) and have it approved by the City Arborist. Approval is usually only granted if the tree is dead, diseased, an imminent hazard, or completely preventing reasonable use of the property.

3. "Heritage" Trees (24 inches DBH and larger)

Any tree measuring 24 inches or larger is a "Heritage Tree." These are fiercely protected. Removing a Heritage tree requires not only a permit but often approval from the Land Use Commission. You must prove that the tree is an absolute safety hazard or that it physically prevents you from accessing or using your property (and even then, you may have to pay high mitigation fees or plant replacement trees).

When is a Permit NOT Required? (The Exemptions)

The City of Austin recognizes that certain trees are invasive or hazardous and actively encourages their removal. You do not need a permit to remove a tree—even if it is larger than 19 inches—if it is one of the following exempt species:

• Hackberry (Celtis occidentalis or Celtis laevigata)
• Ashe Juniper / Cedar (Juniperus ashei) - Note: There are exceptions if it provides habitat for the endangered Golden-cheeked Warbler in western Austin.
• Chinaberry (Melia azedarach)
• Chinese Tallow (Triadica sebifera)
• Tree of Heaven (Triadica sebifera)
• Paper Mulberry (Broussonetia papyrifera)

What if the tree is dead or an immediate emergency?

If a 20-inch oak tree is completely dead, or if it has been split in half by an ice storm and is actively crushing your roof, you still technically need permission to remove it. However, the city provides an expedited "Dead/Diseased/Imminent Hazard" application process.

"If a tree is an immediate threat to life or property, document it thoroughly. Take wide-angle and close-up photos of the damage before any cutting begins. A professional tree service will secure the hazard and process the retroactive permit."

The Fines for Illegal Removal

Cutting down a Protected or Heritage tree without a permit is a criminal misdemeanor in Austin. Fines can run anywhere from $2,000 to over $100,000 depending on the size, species, and location of the tree. The city may also force you to plant dozens of replacement trees to mitigate the canopy loss. It is simply never worth the risk to cut first and ask questions later.
