Summary
Tree trimming in Orange is regulated under OMC Chapter 12.28 for street trees and general property maintenance provisions for private property. Trimming street trees requires a permit from Public Works.
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: ... (2) Remove that portion of a tree that extends within 10 feet of the outlet of a chimney or stovepipe. (3) Maintain a tree, shrub, or other plant adjacent to or overhanging a building free of dead or dying wood. (4) Maintain the roof of a structure free of leaves, needles, or other vegetative materials.
Full Breakdown
Under OMC Chapter 12.28, no person shall trim, prune, or modify any tree or shrub in a public street or right-of-way without a permit from the Director of Public Works. The city maintains a street tree program that handles trimming of city-owned trees. For private property trees, owners are responsible for maintaining trees so they do not create hazards, obstruct sidewalks, block street signs or traffic signals, or encroach on neighboring properties. Tree trimming that constitutes property maintenance is permitted during the hours specified in OMC Chapter 8.24 (7:00 AM to 8:00 PM weekdays, 9:00 AM to 8:00 PM Sundays and holidays). Topping trees, the severe reduction of the main trunk or large branches, is discouraged as it damages tree health and structure.
Violations & Fines
Trimming street trees without a permit violates OMC Chapter 12.28. Allowing private trees to create hazards may result in code enforcement notices requiring correction.
