Summary

In the Town of Southampton outside the villages, no one may erect, alter, enlarge, or demolish a dock, bulkhead, pile, or similar shoreline structure in Town waters without a permit from the Board of Trustees of the Freeholders and Commonalty. Permits run one year, require surveys and plans, and carry a nonrefundable inspection fee before the Trustees will issue them.

§ 47. Permits required; application procedure; issuance; inspections. A. No person shall engage in any of the following activities in Town waters or the bottoms of the Town waters or the bay beach area or ocean beach area as defined herein unless authorized by a permit issued by the Board of Trustees of the Freeholders and Commonalty of the Town of Southampton: ... (3) Erect, construct, reconstruct, alter, enlarge, drive, place, remove, demolish, or deconstruct any structure, including a dock, pile, tie-off poles, moorings, or other obstruction, or bulkhead, jetty, retaining wall, groin, revetment, rip-rap, ramp, catwalk, walkway, stairs, sand fencing or any structure constructed for the purpose of providing access to and from the shoreline ... ... B. Permits will be issued in duplicate, under the seal of this Board, and are good for a period of one year; said permit shall be made out to the owner of the property involved. The original shall be filed with the Clerk of the Board, and a copy shall be kept in the possession of the person in charge of the work at the site thereof, and such permit shall be displayed upon demand.

Full Breakdown

Town Code Chapter A340, Article VII (Dredging, Docks, Bulkheading and Channels) puts every dock, pile, tie-off pole, bulkhead, jetty, ramp, catwalk, or walkway built for shoreline access under the Board of Trustees' permit power under § A340-47. Applicants submit a surveyor's property survey no more than a year old, scaled drawings, site photographs, any recorded covenants, and, where applicable, a Building Department electrical permit; the Board charges a nonrefundable inspection/application fee plus per-structure fees for docks, ramps, catwalks and tie-off poles. Approved permits are issued in duplicate under the Board's seal, run for one year made out to the property owner, and may be renewed for up to four additional one-year terms if the renewal is filed within three months of expiration and the work described has not changed.

The Trustees may require a public hearing on any application that draws significant public interest: the applicant posts a two-by-one-foot sign on-site and mails certified notice to abutting owners at least ten days ahead, the hearing itself cannot open sooner than 15 days after the application is deemed complete, and the Board must close it within 60 days and decide within 45 days of closing. An application sits abandoned, and lapses, if the applicant goes a full year without responding to the Trustees. Only untreated lumber free of chemical preservatives may go into a Trustee-approved dock or bulkhead, a ban in effect since June 3, 2002, and the Trustees reserve the right to inspect any permitted structure and to cancel a permit whenever they find continuing it against the public interest.

Violations & Fines

Building, altering or demolishing a dock or bulkhead in Town waters without first getting Trustees' approval violates § A340-47.A. Any construction activity begun before a permit issues doubles every fee otherwise owed for the application and permit under § A340-47.F(1)(c). The Board of Trustees also reserves the right to cancel an issued permit outright whenever it finds continuing the work is not in the public interest, and every permit stays subject to Trustee inspection for compliance with the application and permit terms.

Frequently Asked Questions

Do I need a permit to build a dock in the Town of Southampton?
Yes. Section A340-47.A bars erecting, altering, enlarging or demolishing a dock, bulkhead or similar structure in Town waters or on the bay or ocean beach areas unless the Board of Trustees of the Freeholders and Commonalty has issued a permit first.
How long does a Southampton dock permit last?
One year from issuance, made out to the property owner. Section A340-47.G allows up to four one-year renewals if you apply within three months of expiration and the described work has not changed from the original permit.
What happens if I build a dock before the permit is approved?
Section A340-47.F(1)(c) doubles every fee that would otherwise apply to the application and permit whenever construction begins without one already issued, on top of whatever standard inspection and per-structure fees the Board charges.
Can my neighbors weigh in on my dock permit application?
Yes, if the Trustees decide the project draws significant public interest. Section A340-47.J requires a posted sign and certified mail notice to abutting owners at least 10 days before a hearing that cannot open sooner than 15 days after the application is complete.
Can I use pressure-treated lumber for a Trustee-approved dock?
No. Section A340-47.I bans any chemical wood preservative on Trustee-approved dock, bulkhead or piling structures, a restriction that has been in effect Townwide since June 3, 2002.
