When do I need to use a NY Licensed Architect or Professional Engineer (P.E.) for what I want to do?

Chapter 92-4 D. (5) (b) of the “Code of The Town of North Salem” requires all construction documents, i.e. plans and specifications, to be prepared by a NYS registered Architect or licensed Professional Engineer. Said requirements are further specified in Article 147; Section 7307 of the NYS Education Law.
