Building a new home on Long Beach Island means navigating municipal zoning rules and FEMA/NFIP floodplain requirements. Each LBI municipality (Long Beach Township, Beach Haven, Harvey Cedars, Ship Bottom, Surf City, and Barnegat Light) has its own code—so what’s allowed on one block may differ a few streets away—and all projects in mapped flood areas must also meet federal standards. 

​

Municipal Zoning Basics on Long Beach Island (lot coverage, setbacks, height)

​

Zoning controls how big your footprint can be, how tall you can build, and where structures and decks can sit on the lot. A few examples from current public documents (always verify your specific zone and lot):

• Long Beach Township: maximum building coverage 33.3% and total impervious up to 75%, with typical front/side/rear setbacks depending on the lot size and setbacks of the houses nearby.

• Ship Bottom and Surf City: Typical building coverage is around 35% and lot coverage around 75%, with front setbacks typically 15–20 ft and sides often 10 ft (or a combined side requirement).

• Harvey Cedars: Harvey Cedars is a little more strict with 29% + 4% open decks (≈33% total), maximum impervious 75%, and a habitable floor area cap of 50% of the upland area.

• Beach Haven: Beach Haven's updated zoning ordinance uses floor‑area caps (often 50%) in certain multifamily and mixed‑use contexts, and treats deck/permitted coverage separately in its schedules. There are also special limitations in Beach Haven's historic district.

​

 Lot coverage and setbacks often determine the size and style of what you can build—so confirming your site’s exact zoning district and standards is step one in Long Beach Island new construction.

FEMA Flood Zones on LBI and What They Mean for LBI New Construction

​

Most of LBI lies in Special Flood Hazard Areas (SFHAs) where FEMA maps flood risk as “A/AE” or “V/VE” zones. The zone you’re in drives both design requirements and insurance:

• Zone VE (Coastal High Hazard Area): areas where 3‑ft or higher waves are expected in the base flood. Structures must meet stricter coastal standards. 

• Zone AE: base flood risk where wave heights are less than 3 ft; still regulated, but with different foundation/enclosure options than VE. 

• Coastal A Zone: portions of AE exposed to 1.5–3 ft waves (mapped with FEMA’s Limit of Moderate Wave Action). Communities are encouraged to build to VE standards here for extra safety and better insurance outcomes.

• Zone X: moderate to minimal flood risk; lenders typically don’t require NFIP flood insurance here, although it’s still recommended. 

​

If you have a mortgage and your property is in a flood zone, flood insurance is usually mandatory on Long Beach Island, and your premium is influenced by how your finished home’s elevations compare to the Base Flood Elevation (BFE). An Elevation Certificate documents those heights for permitting and insurance rating.

Foundations, Elevations & Enclosures for Long Beach Island New Construction

​

VE & Coastal A Zone:

• Homes are typically elevated on open foundations (piles/posts/piers/columns); structural fill is prohibited. The bottom of the lowest horizontal structural member must be at/above the base flood elevation, and any areas below the BFE must remain free of obstruction or use breakaway walls, which is commonplace for new construction in the LBI real estate market (think of almost every elevated home with a garage below).

• Breakaway walls are allowed only as non‑structural enclosures (parking, access, storage) and must be designed to fail under flood/wave loads without damaging the elevated structure.

​

A/AE Zone:

• Enclosures below the elevated floor are allowed for parking/access/storage only and must use flood‑damage‑resistant materials.

• Provide flood openings totaling at least 1 square inch of net open area per 1 square foot of enclosed area, installed per FEMA guidance (height, location, engineered vs. non‑engineered).

​

The design of a home can have a significant impact on the cost of flood insurance and future flooding risks. Adding freeboard above the base flood elevation reduces the risk of damage and can lower insurance premiums; many NJ coastal communities adopt freeboard requirements via local ordinances or CRS participation.

​

On LBI, location (oceanfront, oceanside, bayside, or bayfront) influences both regulatory limits and long‑term value. Maximizing water views within setback/height rules—while meeting the right flood‑resilient design—is central to successful LBI real estate new construction and to the ROI case for building a new home in the LBI real estate market.
