Honolulu County requires permits from the Department of Parks and Recreation Division of Urban Forestry for planting, trimming, pruning, spraying, or removing trees in the public right-of-way across Oahu under ROH Section 10-1.4.
ROH Sec. 10-1.4 governs shade trees, hedges, and shrubs within the public right-of-way island-wide. Urban Forestry issues permits for street-tree work; private arborists must coordinate with the division before cutting any tree on city parkway or easement strips. Countywide context includes monkeypod canopies along windward roads and tall palms in neighborhoods like Kailua and Hawaii Kai. Trees designated exceptional under Chapter 40 Article 8 require separate protection. Homeowner trimming on private property is generally unregulated unless a tree is exceptional.
Unpermitted work on street trees can result in fines, mandatory restoration costs, and replacement-tree obligations assessed by Urban Forestry.
