All businesses that advertise, offer, or perform tree trimming in Broward County are required to obtain a Tree Trimmer License. Licenses are valid for a maximum of two years. Sherlock Tree Company has a Class A Tree Trimmer License - No. A-1205. Below are details about this license from the Broward County website -  Article 11 of the Broward County Natural Resource Protection Code outlines regulation of the tree trimming industry. This action was taken as a result of concerns about the quality of tree trimming practiced in Broward County, and to protect the health, safety and welfare of the public. Purpose:​ Through continuing education, this ordinance reduces the frequency of poor pruning practices such as over lifting, rounding, flush cuts, stub cuts, hat racking and other forms of pruning-related tree abuse. These poor pruning practices damage trees, reduce their aesthetic value and can make them more prone to storm-related failure, creating hazardous situations. Tree abuse is prohibited under Chapter 27, Article 14 of the Broward County Code of Ordinances. Two classes of licenses are issued, depending upon the level of professional training an organization‘s staff has achieved: Class A Tree Trimmer License:​ Requires a sole proprietor or a qualified individual for a business organization or a governmental agency to possess an International Society of Arboriculture Arborist Certification or be a Registered Consulting Arborist with the American Society of Consulting Arborists.
