Which of the following is NOT required to have a license according to the exempted operations?

A project manager is not typically required to hold a home improvement license under the exempted operations because their role often focuses on coordinating and overseeing projects rather than engaging directly in the actual construction or home improvement work. Project managers generally do not perform the physical tasks of construction but rather manage budgets, schedules, and teams.

The other roles mentioned, such as a licensed contractor's employee, a professional engineer, and a contractor specializing in home maintenance, are often tied to directly licensed work or professional endorsements that require validation through licensing. These positions directly involve skilled work or professional responsibilities that typically fall under the licensing requirements established by Suffolk County.
