The 10-point waterfront checklist
| ✓ | Check | What to look for |
|---|---|---|
| ☐ | Cap and wales | Rotted, split or missing cap boards and walers; loose or rusted hardware. |
| ☐ | Alignment | Sight down the wall. Any lean, bulge or belly toward the water suggests failed tie-backs or deadmen. |
| ☐ | Behind the wall | Sinkholes, dips, soft spots or settling lawn within about 10–15 ft of the wall: soil is washing out. |
| ☐ | Face of the wall | Gaps between boards or sheets, holes, cracks, missing sheathing, daylight at low tide. |
| ☐ | At the bottom (toe) | At low tide, look for scour holes or exposed piles at the base. |
| ☐ | Pilings | Necking at the waterline, soft or hollow wood, shipworm damage, rusted steel. |
| ☐ | Returns | The short walls tying into the neighbors: separated, leaning or missing returns leak. |
| ☐ | Height | Compare to the neighbors' walls. Is there wrack or a water line on the lawn from overtopping? |
| ☐ | Dock and lift | Decking, framing, piling condition, lift beams and cables, power at the dock. |
| ☐ | Paperwork | Year built or replaced, material, prior permits (DEC, Army Corps, town or Trustees), repair records. |
Why permits matter at resale
DEC's fast-track general permit covers replacing a functional, lawfully existing bulkhead. A wall with no permit history, or one that's been pushed out over the years, can mean a slower individual permit when it's time to replace it. Ask for the paperwork before you're in contract.

Frequently asked questions
Should I get a bulkhead inspection before buying a waterfront house on Long Island?
Yes. Home inspectors usually don't cover them: InterNACHI's standards of practice say inspectors aren't required to inspect seawalls, breakwalls or docks. A marine structure inspection typically costs $300–$600, which is small next to a replacement that can run $50,000–$100,000 on a typical lot.
What paperwork should the seller have?
Ask for prior DEC, Army Corps and town or Trustees permits for the bulkhead and dock, the year they were built or replaced, and any repair invoices. A permitted, lawfully existing wall is what qualifies for DEC's fast-track replacement permit later.
Can I use a failing bulkhead to negotiate?
Many buyers do. Get the inspection and a written repair or replacement estimate before contract. That turns "needs some work" into a number.
