Tree removal laws and permits in Austin: what homeowners need to know

Removing a tree in Austin isn’t always as simple as calling a crew and scheduling a day. The city protects certain trees under its heritage tree ordinance, and skipping the permit process when one applies can mean fines or a mitigation requirement you didn’t budget for.

This is general information, not legal advice. Confirm current requirements with the City of Austin or a licensed arborist before removing a tree.

When a permit is required

Austin’s ordinance protects trees above certain trunk diameters, with additional protection for a defined list of heritage-sized species, large live oaks in particular. The exact size thresholds vary by species, so the only reliable way to know if your tree qualifies is to have it measured, either by the city or by a licensed arborist familiar with the ordinance.

Tree situation	Typical requirement
Small tree, non-protected species	Often exempt, confirm before removal
Large tree, protected species	Permit required
Heritage-sized live oak	Permit required, stricter review
Dead or hazardous tree	Often still needs review, may be expedited

What the permit process involves

Once an application is filed, the city typically reviews the tree’s condition, size, and species. For heritage-protected trees, this can include an arborist assessment and, in some cases, a public notice or hearing period before approval. A company experienced in Austin tree work should be able to walk you through this timeline honestly rather than promising a same-week removal for a tree that clearly needs review.

What happens if you skip it

Removing a protected tree without going through the process can result in a fine, and the city may require mitigation, such as planting replacement trees elsewhere on the property or paying into a tree fund. These outcomes vary by situation, so if you’ve already had a tree removed and are unsure whether it needed a permit, it’s worth checking with the city directly rather than guessing.

Working with a company that knows the process

Ask any tree service you’re considering whether they pull permits as part of the job or expect you to handle it yourself. A company that regularly works in Austin should know the size thresholds and be upfront if your tree likely qualifies for protection, rather than quoting a fast removal and leaving the permit question for you to sort out. This is also where hiring a company with a documented history of professional communication pays off: permit timelines can shift, and you want a crew that keeps you updated rather than going quiet.

Before you remove anything

If a tree is near a property line, get confirmation of exactly where the boundary sits before removal, since disputes over trees that straddle a line are common and harder to resolve after the fact. And if the tree is dead, damaged, or clearly a safety risk, document its condition with photos before removal in case the permit process asks for that evidence later.

Trimming vs removal

Not every question about a protected tree involves full removal. Significant trimming or pruning of a heritage-protected tree can also fall under the ordinance in some cases, particularly if it affects the tree’s structure or health, so it’s worth asking a company doing major pruning work whether their plan needs the same kind of review. Routine, light trimming for shape or safety generally does not trigger this, but a large reduction in canopy might.

What if you disagree with a permit decision

If a permit application is denied or the required mitigation feels disproportionate, there is usually an appeals process through the city. This is a more involved path and typically benefits from an arborist’s written assessment supporting your case, since a denial is more likely to be reconsidered with documented evidence about the tree’s condition than a general objection alone.
