Anchorage lets owners trim trees on their own property freely. Branches over streets must clear 14 feet, over sidewalks 8 feet, under AMC 24. Boulevard trees need MOA Parks approval.
Private trees on residential lots can be trimmed without a permit. AMC Title 24 (streets) requires that branches overhanging public streets be pruned to 14 feet of vertical clearance and branches over sidewalks to 8 feet, to keep plow trucks and pedestrians safe. Adjacent property owners are responsible for this clearance. Boulevard trees (planted in the municipal right-of-way between sidewalk and curb) are technically MOA property and require a permit from Parks and Recreation Urban Forestry before any structural pruning or removal. Self-help trimming of a neighbor's branches that cross the property line is allowed up to the line but cannot kill the tree — Alaska follows the Massachusetts rule on encroaching branches. The short summer means most pruning happens April-May before leaf-out or in late August.
Failure to maintain clearance: warning then 100 dollar citation. Unauthorized pruning of a boulevard tree: 500-2,000 dollar fine plus tree replacement cost.
