Tree trimming on private property in Suffolk County generally requires no permit unless the tree is a protected species, a street tree, or in a regulated area (Pine Barrens, wetlands buffer, historic district). Each town maintains its own tree preservation ordinance, and utility trimming by PSEG Long Island follows NY PSC rules.
Brookhaven Chapter 31, Smithtown Chapter 273, and Huntington Chapter 183 govern trimming of trees on town-owned property and street trees. Any pruning of a street tree (within the public right-of-way) requires a free permit and must follow ANSI A300 standards. On private property, heritage trees and specimen trees (varying diameter thresholds by town, typically 18-24 inches DBH) require permits for major pruning beyond 25% of the crown. PSEG Long Island conducts utility line clearing under regulated cycles.
Unpermitted street tree trimming: $250-$500 per tree. Topping or improper pruning of protected tree: $1,000-$5,000 plus replacement. ANSI standard violations by commercial tree services: license suspension.
