Oyster Bay, NY Environmental Rules: Boat Dock Permits (2026)

Town Code § 241-7 puts docks, moorings, piers, bulkheads and floats built or modified in the unincorporated areas of the Town under the jurisdiction of the Department of Planning and Development, administered together with Chapter 93 (Building Construction) and Chapter 246 (Zoning); structures within an incorporated village fall to that village instead once Planning confirms they do not encroach into Town waters. S. Army Corps of Engineers, a survey of plans and specifications including telephone, electrical and water service, and a radius map covering all structures on the two properties on each side of the site (four properties total) plus any waterfront parcel directly across the waterway, with a mean-low-tide chart of the area within 300 feet.

The applicant must mail notice of the filing to those neighboring owners and certify the mailing. The Commissioner of Planning and Development decides completeness, routes the file to the Division of Environmental Planning and Technical Review under Chapter 110 (Environmental Quality Review), and consults the Parks Department Division of Beaches and Marinas. If the proposed structure stays within the property's riparian line, the Commissioner decides the application; if it would extend beyond that line, the Commissioner forwards it with a recommendation to the Town Attorney's Legislative Affairs office for a Town Board resolution, which requires 14 days' written notice to the same neighboring owners before the Board hearing, at the applicant's expense.

Section 241-10 sets construction standards: no electrical wiring without Commissioner approval and an electrical inspection certificate; no mooring that interferes with adjacent beaches, moorings, docks or navigation; plumbing must meet Chapter 180 and the NYS Building Code; any mooring longer than 25 feet or over 200 square feet needs an accessible personal flotation device tied to a 100-foot, four-hundred-pound-strength nylon rope; walking surfaces need nonslip material; no dock or pier without an adjacent dwelling or building unless the Zoning Board of Appeals grants special permission; piers and docks up to 50 feet long must be at least three feet wide, longer ones at least four feet wide; and any structure extending more than 30 feet past mean high tide needs a four-square-inch reflective device every 20 feet along its length.
