Effective January 1, 2017, the fee schedules for the Department of Planning & Development will change. For many years the fees have remained unchanged despite continually increasing expenses. The updated fee schedules are comparable to that of other Suffolk County municipalities. Some fees are increasing, while others remain the same or have been reduced. You can find the new fee schedule on each Division’s webpage.

Any application filed with the Planning Division that obtains Planning Board and/or Town Board required approvals, and files with Building or Engineering Divisions prior to April 1, 2017, the 2016 fee schedule will apply. Applications and plans submitted that are not substantively complete, the application will not be grandfathered under the 2016 fee schedule.

The Town of Islip is implementing a Compliance Incentive Program to allow projects that were previously completed without a permit to be brought into compliance. The program is aimed at protecting public health and safety by encouraging commercial property owners to complete the Town’s permit process.  The Town’s goal is to ensure that buildings are safe, habitable and in compliance with the New York State Building Code, as well as the Islip Town Code.  To encourage participation by local businesses, the Town is discounting its Certificate of Compliance fees for commercial properties by 40%.

In addition to ensuring that safety issues are addressed by legalizing their properties, the owners will have assurance that work completed will not void any insurance claims, and they will have the permits required by financial institutions for loans and refinancing.  Commercial property owners are encouraged to take advantage of this short-term Compliance Incentive Program as soon as possible.  The Town does not anticipate renewing this program after it ends.  

"This is a one-time program designed to remedy a serious public safety issue. I urge property owners to come forward and bring their buildings up to code," said Supervisor Angie Carpenter. "Our inspectors and Planning Department officials are eager to work with these local businesses and guide them through this process."

To be eligible for this temporary program, the unpermitted activity must have occurred prior to January 31, 2013 and a complete Certificate of Compliance permit filed with the Building Department by May 31, 2017.  If the Town grants a permit, the previously unpermitted structure must be brought into compliance within one year.  If a violation has been reported and an appearance ticket issued, property owners will no longer qualify for this program. Enforcement efforts will be increased once the Compliance Incentive Program officially ends.
