Summary

99] ( Chapter 3 added by Stats. 1965, Ch. 1144. ) 4291. (a) A person who owns, leases, controls, operates, or maintains a building or structure in the state responsibility area shall at all times do all of the following: (1) (A) Maintain defensible space of 100 feet from each side and from the front and rear of the structure, but not beyond the property line, except as provided in subparagraph (B). The amount of fuel modification necessary shall consider the flammability of the structure as affected by building material, building standards, location, and type of vegetation. Fuels shall be maintained and spaced in a condition so that a wildfire would be unlikely to ignite the structure.
Full Breakdown
Tuolumne County does not have a general ordinance regulating routine trimming or pruning of ordinary trees on private property; there is no permit for ordinary maintenance pruning. Three narrower rules can apply. 24 (Premature Removal of Native Oak Trees, Ord. 2903, 2008), which is triggered by removal in connection with a discretionary land-development entitlement rather than by ordinary pruning, but heavy cutting that effectively kills or destroys a protected oak can fall under it. 14) expects removal of 'ladder fuels' and low limbs that let fire climb into the tree canopy, and it calls for pruning low tree limbs as part of the Reduced Fuel Zone, while expressly not requiring removal of healthy, mature, scenic trees.
040(C)) direct that mature vegetation be planted no closer than 10 feet to power lines, reflecting the standard utility line-clearance practice (PRC 4293) that lets utilities prune trees away from energized lines. For ordinary shade-tree pruning on a residential lot, none of these create a permit requirement. 24.
Violations & Fines
Ordinary pruning of non-protected private trees carries no county penalty. Cutting that kills, destroys, or prematurely removes a protected native oak in connection with a land-development project can trigger Chapter 9.24 mitigation, fines, and permit deferral. Failing to remove ladder fuels and low limbs in a required Reduced Fuel Zone is a Chapter 8.14 hazardous-vegetation matter enforced by the Fire Prevention Division.
