A permit is needed to remove a protected-species tree (Texas ash, bald cypress, American/cedar elm, Texas madrone, bigtooth maple, all oaks, pecan, walnuts) 12"+ in diameter on a residential lot; replacement trees are required. No oak trimming Feb 1 to Jun 30 ($500 fine).
How to apply: Apply to the City of Rollingwood for a tree removal permit (City Hall, 512-327-1838).
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.
