Tree Services and Arborists: Permits and Credentials in TX and FL

Neither state licenses tree trimmers, so look for an ISA-certified arborist and ask about local tree rules before cutting. In Florida, a local government can't require a permit or fee to remove a risky tree on a single-family lot if an ISA-certified arborist or Florida landscape architect documents the risk. In Texas, cities such as Austin require permits for large protected trees.

Florida limits local rules: with documentation from an ISA-certified arborist or Florida landscape architect that a tree poses an unacceptable risk, a local government can't require a permit, fee or replanting on a single-family lot (Florida Statutes 163.045). The exception doesn't cover mangrove protection.
