Islip, NY Sidewalk & Pedestrian Rules: Encroachment Permits (2026)

Code of the Town of Islip § 47A-32 bars constructing or repairing any sidewalk, curb or gutter along a Town street, road, highway or parkway, or even starting work on one, until the owner (or the owner's authorized agent) has obtained a permit. Applications must be made in writing to the Superintendent of Highways in the form the Town Board requires, and no permit issues without the Superintendent's endorsed approval unless the Town Board directs otherwise by resolution. Section 47A-38 sets the fee at $10 for each installation.

Section 47A-29 layers on additional requirements when the work follows a Town Board order to construct or repair: the property owner obtains the permit under §§ 47A-25 through 47A-40, while work on a state highway with state-built sidewalks or curbs instead requires a permit from the state Department of Public Works' highway division. The Superintendent may condition any permit on bonds or deposits considered necessary to protect Town property. Larger jobs also trigger insurance under § 47A-36 (workers' compensation, and public liability/property damage coverage of at least $300,000/$500,000 bodily injury and $100,000/$200,000 property damage, or a $1,000,000 combined single limit) and a performance bond under § 47A-37 in at least the amount of the job.

Section 47A-34 makes clear this sidewalk/curb permit is in addition to, not a substitute for, any separate street-opening, excavation or curb-cut permit that may also be required.
