A Message from the Supervisor

“Welcome to Islip, the 3rd largest town in New York State, but with an endearing small town feel. We are so proud of our town…our beaches, golf courses, marinas, parks, housing opportunities for all, businesses, industrial parks, healthcare and educational institutions including our own Islip MacArthur Airport that provides many job opportunities. I sincerely hope you find this website helpful.” - Angie

PLANNING & DEVELOPMENT

CLICK HERE to View Planning & Development Operations and Temporary Application Process Requirements During COVID-19

The Planning & Development Divisions, while closed to the public during the COVID-19 virus, are continuing to operate ensuring that applications are processed and constituent inquiries are answered in a timely manner. The offices are staffed at 50% in order to comply with the Governor’s mandate for social distancing for essential services, and the balance of our staff is working from home to ensure the public continues to be served.

While our process has changed slightly, Planning, Engineering, Building and the Zoning Board of Appeals Divisions are still committed to processing your applications as quickly and efficiently as possible. A cursory review is still required to minimize unnecessary delays in the processing of incomplete applications. Building, Plumbing and Engineering inspections will continue for any construction permitted under Governor Cuomo’s executive order.
