Pinal County has no general residential tree-trimming ordinance for private yards. The main county rule is that vegetation must stay clear of sight-visibility triangles at intersections (21'x21' local, 33'x33' others) and not obstruct county roads or rights-of-way.
For a tree entirely on your own unincorporated lot, Pinal County does not dictate pruning schedules or heights. Where the county does regulate is the public right-of-way: the Subdivision & Infrastructure Design Manual requires Sight Visibility Triangle Easements at intersections be kept clear of visual obstructions, sized 21' x 21' at local-to-local intersections and 33' x 33' at arterial or collector intersections. Branches overhanging a county road or blocking driver sightlines can be ordered trimmed. Protected native trees (ironwood, mesquite, palo verde, saguaro) are separately governed by state native-plant law before removal. Inside incorporated cities, the city's own tree/ROW code applies.
Vegetation obstructing a sight triangle or county right-of-way may be ordered abated by Public Works; failure can lead to county abatement and cost recovery.
