Removing a protected (8–20"), signature (20–30") or heritage (30"+) tree needs approval, in the city and the ETJ. Exempt: dead or diseased trees (certified arborist), safety threats (ISA TRAQ arborist, letter within 10 days), and hackberry, eastern red cedar, Ashe juniper, chinaberry, mesquite, ligustrum, Chinese tallow and Bradford pear. Mitigation 1:1, 3:1 or 4:1.
How to apply: Submit a written tree removal request on the City form to Buda Development Services. Signature trees go to Planning & Zoning; heritage trees go to City Council after a public hearing.
Texas law: cities cannot charge a tree mitigation fee for a tree under 10" at an existing one- or two-family home you live in (Local Gov't Code §212.905, HB 7, 2017). Since 2023, landowners can petition to leave a city's ETJ (SB 2038), so ETJ lines change; we read the live City of Austin jurisdiction map.
