Cost depends on your flood zone, lot conditions, and finishes, not just square footage.
What Makes a Great Builder on Long Beach Island?
Building on LBI isn't like building in a subdivision off the Parkway. It's an 18-mile barrier island with one causeway on and off, tight lots, flood maps that shape nearly every design decision, and a summer season that sets the construction calendar.
So the builder matters more here.
National production builders like Toll Brothers and Lennar are mostly set up for planned communities, where a few floor plans repeat across hundreds of lots. That model rarely fits an oceanfront lot in Harvey Cedars or a narrow bayside parcel in Beach Haven. Island homes are one-offs, and the builders below treat them that way.
We looked at each company's history on the island, the range of services it offers, and how clearly it explains its process. Here's the list.
The 10 Best Custom Home Builders on LBI
1. Nardini Custom
Plenty of builders send you off the island to pick cabinets, flooring, and countertops. Nardini Custom doesn't. The company runs a design center at 619 Long Beach Boulevard in Ship Bottom, with a second showroom in Red Bank, where clients choose cabinetry from lines like Plain and Fancy and Yorktowne, countertops from brands like Cambria and Caesarstone, and flooring from hardwood to luxury vinyl plank, with design help on hand. According to the company, its cabinets are made in Lancaster, Pennsylvania.
That retail side comes from history. The Nardini family has been in the housing business since 1934, starting as an electrical contractor in Bayonne and expanding into flooring, kitchens, and retail before becoming a turn-key design-build firm. Owner Tommy Nardini started as a floor-laying craftsman in his early teens. By sixteen, he was running crews. Visitors to the showrooms may also meet Lucia Nardini, an award-winning kitchen designer.
The process is spelled out in unusual detail. Nardini Custom's custom home building services start with pre-construction deliverables like design proposals, construction documents, a master schedule, detailed estimates, sourced materials, and permits. After the build, clients get a punch list, equipment training, a custom homeowner manual, and a warranty walkthrough 11 months after construction, timed so issues surface while first-year coverage still applies.
Projects include new beachfront construction in Surf City and a rooftop pool on a beachfront LBI home. The team also handles renovations, roofing, siding, decks, and storm damage repair, which helps when an older house needs more than one trade.
2. Michael Pagnotta Architecture & Construction
Based on West Ninth Street in Ship Bottom, this firm has focused on custom coastal homes since 1990. Its model is architect-led design-build, where the architect also leads construction, so you get a single point of responsibility. The firm's work includes narrow lot, contemporary, and oceanfront homes, and it helps clients sort through zoning and CAFRA questions. It's a different setup from a builder who simply hires an architect.
3. Mancini Custom Homes
Few names go back further on the island. Mancini Custom Homes, based in Beach Haven Gardens, says the Mancini family has built more than 1,000 custom homes on LBI since 1954. The company's ties to real estate mean it can also help buyers find waterfront or water-view lots to build on.
4. Walters Homes
Walters Homes in Ship Bottom keeps architecture, interiors, and construction in-house, and it has more than four decades of experience. Its Walters Real Estate arm helps clients find land, and its website gives a realistic timeline: about 12 to 14 months from contract to move-in, including engineering, permits, and six to eight months of construction.
5. Ziman Development
Ziman Development has been building on LBI since 1998 from its office in Harvey Cedars. It builds on a client's lot or its own, and it walks clients through a five-step process that begins with an idea session. The company says most of its custom homes take 12 to 18 months from permit approval, and its client builds typically start at $2 million.
6. JDM Andrews Custom Homes
Family owned and operated for more than 30 years, JDM Andrews works out of Ship Bottom. Its portfolio covers oceanfront homes in Brant Beach and bayside homes in Harvey Cedars, which is a good range for buyers weighing both sides of the island.
7. Shore Builders Group
Shore Builders Group, a family-run Ship Bottom company with about 30 years on the island, does more than new construction. Its services include custom homes, additions, renovations, house raising, and house watching. That last one matters for owners who aren't on LBI full-time.
8. Callan & Moeller Construction
Callan & Moeller is a Ship Bottom builder focused on custom and luxury homes. The company has developed neighborhoods like Sounds Edge and Bridge Tender, and client reviews on its site mention its willingness to modify existing house plans.
9. JS Pro Construction
Founded in 2005 and based in West Creek, JS Pro Construction builds luxury custom homes across LBI and the mainland nearby. Two details stand out. It deliberately limits how many projects it takes on each year, and it says most builds take 6 to 10 months depending on size and complexity. It also offers additions, renovations, and property management.
10. Andev Builders
Andev Builders, a family-owned company that's been building homes since 1986, serves LBI and Manahawkin, works directly with architects and owners on custom designs, and lists a 2-10 Home Buyers Warranty.
How to Choose the Right LBI Builder for You
Every company above has built on the island. But which one fits your project?
Start with registration. New Jersey requires new home builders to register with the Department of Community Affairs, and a builder can't get a permit for a new home without it. You can check any company on the state's list of registered new home builders. Covered new homes also come with limited 10-year warranty coverage under state law, so ask how each builder handles warranty claims.
Then compare timelines honestly.
Notice how differently the builders above describe them? One counts from contract signing, another from permit approval, and another counts construction only. Ask every builder what their number includes so you're comparing the same thing.
Timing matters too. Most owners want to build in the off season so the house is ready to enjoy or rent by summer, which makes fall through spring the busiest stretch on the island.
And look at the finished work in person. Decks, siding, and trim show salt air wear first, and a home that still looks sharp after a few winters says more than any rendering. Ask for addresses.
Frequently Asked Questions
How much does it cost to build a custom home on Long Beach Island?
It varies widely with lot, flood zone, size, and finishes. Elevated foundations, coastal-grade materials, and island logistics generally push costs above mainland builds, so get detailed written estimates from more than one builder.
How long does it take to build a custom home on LBI?
It depends on the builder and the project. Published estimates from LBI builders range from 6 to 10 months of construction to 12 to 18 months after permits are approved. Design and permitting add time on top of that.
Do custom home builders in New Jersey need to be registered?
Yes, New Jersey requires builders of new homes to register with the Department of Community Affairs, and permits for new homes can't be issued to unregistered builders.
What's the difference between a builder and a design-build firm?
A builder typically constructs a home from plans you bring. A design-build firm handles design and construction under one team, so you have a single point of contact from first sketch to move-in.
When is the best time to start building on LBI?
Most owners start planning well before the off season. Fall through spring is the most popular time to build. Design and permits can take months, so early planning helps.
Do I need an architect to build a custom home on LBI?
Not always. Some builders work from an architect's plans, while others have architects or designers in-house, and either way the plans have to meet local zoning and flood rules.
