Historic Overlay District (HOD) provisions add enhanced tree protection on regulated properties. Durham Unified Development Ordinance (UDO) §9.8 Tree Protection regulates significant trees and heritage trees on all non-single-family-residential development sites. Significant trees: ≥12 inches DBH for most species. Heritage trees: ≥24 inches DBH or any tree of exceptional size, age, or historical significance designated by the City/County Arborist.
