When do I need a tree permit? If you live within the City of Austin zoning jurisdiction a Tree Ordinance Review Application is required when removing a protected size tree (or if you are performing construction work within the Critical Root Zone). Regulations about protected sized trees are online.

What are the steps for removing a protected size tree within the City of Austin? If you have a protected size tree within the City of Austin, complete and submit the Tree Ordinance Review Application and pay the applicable fee. Once these items are complete City staff will perform a site inspection and contact you about your request.

What size trees are protected? A protected size tree is determined by measuring the tree trunk at 4.5 feet above ground. This is commonly known as DBH (diameter at breast height). The tree, within the Austin city limits, is protected once it reaches 19 inches. Diameter = Circumference / 3.1416 and Circumference = Diameter X 3.1416.

What is the purpose of a tree survey? A tree survey tag is usually an aluminum circular or rectangular label attached to the tree trunk. A tag is used for physically identifying a tree with a specific number. This number is referenced on a site plan or survey. It does not mean the tree is marked to be saved or removed.
