TOWN OF ISLIP — BUILDING DIVISION OPERATIONS
One Manitton Court, Islip NY 11751
8:00am – 4:00pm, Monday – Friday
(not including holidays)
The Building Division falls under the umbrella of the Planning and Development Department.
The Building Division administers building and plumbing permit applications which are reviewed for compliance with New York State Uniform Code, the Town of Islip Zoning Code and the Subdivision and Land Development Regulations.
Permit applications must be filed electronically. Electronic filing not only helps streamline the review process, it also has economic and environmental benefits by saving on paper and gas.
Please follow the directions detailed in the Electronic Submittal Process flyer located on our webpage under Permit Applications.
Applications and paperwork can be placed in the Drop-Off Pail located by the entrance to the Building Division. Please make sure your contact information is included in your package.
If you are picking up a Permit or CO, the Permits or Records Department will notify you when it will be available for pickup in the Pickup Bin. If you owe any paperwork or fees, please visit the appropriate department to complete your transaction.
The Drop-Off and Pickup Bins will be accessible during normal business hours.
FOIL requests should be submitted online; follow the directions at islipny.gov/foil. If you do not have access to a computer, you can pick up a form at the Records Office, and drop off the completed form in the Drop-off Bin.
FOIL requests will be processed in the order in which they were received and will not be processed at the counter.
The Permits Department manages the permitting process from intake to permit issuance.
