Treecode NYC was created to simplify and modernize the complex relationship between developers and the New York City Department of Parks. In a city where every project must balance growth with environmental responsibility, Treecode translates municipal regulations, permit requirements, and arboricultural standards into clear, actionable processes.


Elliott Norman, former Forester for the NYC Department of Parks within the Permits and Plan Review Division, is an environmental professional dedicated to sustainable urban forestry. As founder of TreecodeNYC, and LEED Accredited Professional in Neighborhood Development, he advances green infrastructure, tree care education, and community environmental awareness across New York City.
All permit applications for the NYC Department of Parks, including Tree Work and Construction Permits, can be applied for through the Tree Work Permit and Plan Review Application on the nycgovparks.org website. Make sure you have the right materials when applying for your permit.
