Do You Need a Permit for a Dock, Boat Lift or Bulkhead in New Jersey?

In most cases, yes. NJDEP says you need a permit before you build in New Jersey's coastal zone under most circumstances, and it names docks, boat lifts and jet ski lifts as common examples. A dock, lift or bulkhead that sits on State-owned tidelands also needs a tidelands license, which is a separate approval. Which permit applies depends on the project and the water it's on.

I'm Dennis Mark Interdonato with The Dennis Mark Group. I'm a former New Jersey home builder and residential remodeler, and on waterfront homes in Monmouth and Ocean County the dock and bulkhead are part of what you're buying. Here's how the State's permit system is set up, from NJDEP's Coastal Zone and Tidelands pages.

Who regulates docks and bulkheads in New Jersey?

NJDEP's Division of Land Resource Protection handles land use permitting in the State's regulated areas. For waterfront work, the laws it lists include the Coastal Area Facility Review Act (CAFRA), the Waterfront Development Law, the Wetlands Act of 1970, the Tidelands Act and the Flood Hazard Area Control Act. Staff review coastal applications under those laws and the Coastal Zone Management Rules, N.J.A.C. 7:7.

The coastal zone is large. NJDEP says it covers parts of 17 counties and 239 municipalities and runs from the Hudson River along the Raritan Bay, then from Sandy Hook down to Cape May Point and up the Delaware Bay and River, about 1,792 miles of coastline in all.

What kinds of coastal permits are there?

NJDEP lists several, depending on the project:

• Permits-by-rule and permits-by-registration for certain smaller activities (Subchapter 4 of the Coastal Zone Management Rules)
• General permits-by-certification for three specific activities (Subchapter 5)
• General permits for defined activities, available only when every requirement in the rule is met
• Individual permits for projects that don't fit the others
• Emergency authorizations

NJDEP's own guidance: if a project isn't on its lists of permits-by-rule, general permits-by-certification or general permits, it likely needs an individual permit.

Which general permits cover docks, lifts and bulkheads?

Several of NJDEP's coastal general permits apply to residential waterfront work, including:

• General Permit 6: construction of a bulkhead and placement of associated fill on a man-made lagoon
• General Permit 10: reconstruction of a legally existing, functioning bulkhead
• General Permit 14: bulkhead construction and associated fill at a single-family home or duplex lot
• General Permit 15: construction of piers, docks, jet ski ramps, pilings and boat lifts in man-made lagoons
• General Permit 16: minor maintenance dredging in man-made lagoons
• General Permit 24: habitat creation, restoration, enhancement and living shoreline activities

Each one has conditions. NJDEP warns that if a project doesn't meet all of a general permit's requirements, the application will likely be denied and a different permit may be needed.

When does a dock or bulkhead need an individual permit?

NJDEP says activities in tidal waters, at or below the mean high water line, that don't meet a permit-by-rule, general permit-by-certification or general permit need a Waterfront Development Individual Permit. Its example is direct: in most cases, installing docks, piers, jet ski ramps, boat lifts and bulkheads on natural waterways requires one. All the activities in a project can be reviewed under one application, and NJDEP suggests a pre-application meeting for individual permits because they're more complex.

How does the tidelands license fit in?

The permit approves the construction. The tidelands license covers the use of State-owned land under the water. NJDEP requires a license for fixed structures on currently flowed tidelands, which it defines to include docks, piers, mooring piles, floating docks, boat lifts and riprap that stay more than ten consecutive days, and for bulkhead reconstruction or extensions that go past the mean high water line. The full picture of grants, licenses and leases is in what is a riparian grant.

How do you check a property before you buy?

1. Ask for the paperwork. Permits and tidelands licenses for the dock, lift and bulkhead, plus any engineering or contractor records.
2. Use NJDEP's tools. NJDEP has an online mapping tool to see whether a project location falls in the coastal zone, a permit applicability check, and an online application status search.
3. Check with the town. Local construction and zoning requirements can apply on top of the State's, so your contractor or the town's construction office should confirm them.
4. Plan changes before you sign. If you want to add a lift, extend a dock or rebuild a bulkhead, talk to a marine contractor or engineer about which permit route applies before your attorney review period ends.

When I walk a waterfront home with a buyer, I look at the dock and bulkhead with a builder's eye and tell you what I'd want a marine contractor to look at more closely. The contractor, the engineer and NJDEP have the final word.

Frequently Asked Questions

Do I need a permit to repair or rebuild my bulkhead?

Usually some approval is needed. NJDEP's General Permit 10 covers reconstruction of a legally existing, functioning bulkhead, and a tidelands license is required for reconstruction that goes past the mean high water line. Your contractor confirms which applies.

Do I need a permit for a boat lift on a lagoon?

NJDEP's General Permit 15 covers piers, docks, jet ski ramps, pilings and boat lifts in man-made lagoons, if all of its conditions are met.

What's the difference between a permit and a tidelands license?

The permit approves the construction. The license is the State's rental agreement for using State-owned tidelands. A dock on tidal water can need both.

Does a floating dock count as a structure?

Yes, for tidelands licensing. NJDEP lists floating docks and jet ski floats among the fixed structures when they occupy currently flowed tidelands for more than ten consecutive days.
