Is a Major Renovation Worth It for an Older LBI Shore House?
Key Takeaways
For a lot of older LBI homes, yes. But only when the numbers and the flood rules line up.
Under FEMA’s rules, if your project costs equal or exceed 50% of the building’s market value (land not included), the house generally has to meet current floodplain standards.
Some towns, including Surf City, look back at 10 years of permits, so splitting work into phases won’t always keep you under the line.
A sound foundation, solid framing, and a layout you mostly like are the strongest signs a renovation will pay off.

Why So Many LBI Owners Are Asking This Question
Drive down Long Beach Boulevard and you’ll see older shore cottages sitting right beside brand-new elevated homes.
If you own one, you’ve probably wondered whether it’s worth putting serious money into it. Maybe the kitchen hasn’t been touched in decades, or the last storm left you wondering what’s hiding behind the walls.
We’re Nardini Custom, a turnkey design-build firm with a design center on Long Beach Boulevard in Ship Bottom. Our family has been in the housing business since 1934, and our owner, Tommy Nardini, started out laying floors in the family business at thirteen. Here’s how we’d think through this decision if it were our own shore house.
The Honest Answer Depends on Three Things
Forget the before-and-after photos for a minute.
Whether a major renovation makes sense usually comes down to what the structure is worth today, what the work will cost, and what you want from the house long term. A family keeping a summer home for the next generation sees it one way. Someone renting it out every week, or planning to sell soon, sees it another.
The first two are where people get surprised. On LBI, the land often makes up a big share of a property’s price, and that matters once flood rules come into play.
The 50% Rule Can Turn a Renovation Into a Rebuild
Here’s the part most renovate-or-rebuild articles skip entirely. Under FEMA’s National Flood Insurance Program, a project counts as a substantial improvement when the cost of the work equals or exceeds 50% of the structure’s market value before construction starts.
Once a project crosses that line, the house generally has to be brought up to current floodplain requirements, which can mean elevating it. Your town makes that call, not your contractor. And because the math uses the building’s value alone, an older house with modest square footage can hit 50% faster than you’d expect.
Picture a cottage where the building itself is valued at $250,000. A $130,000 gut renovation would already be over the threshold.
Watch Out for the Look-Back Period
Phasing the work doesn’t always get you around the rule. Surf City, for example, adopted an ordinance requiring the borough to evaluate permits issued over a period of ten years when deciding whether work counts as a substantial improvement. Rules can differ by town, so ask your local construction or floodplain office early.
So what if you’re likely to cross 50% anyway?
Then the conversation changes. In some cases it makes more sense to put that money toward a new, elevated home built to current standards. We do both renovations and custom home building, so we’ve got no reason to push you one way or the other.
Signs a Major Renovation Is Worth It
Older shore houses that renovate well tend to share a few traits.
The Foundation and Framing Are Sound
If the foundation is in good shape and the framing hasn’t been worn down by salt air and moisture, you’re starting from a strong position. A structural engineer can confirm it before you commit. Generally speaking, that’s money well spent on any older house near the water.
Your Wish List Fits the Footprint
Not every upgrade needs more square footage. A new kitchen, new hardwood or luxury vinyl plank flooring, updated baths, and a more open first floor can often happen inside the existing walls. Our first-floor renovation in Oceanport, covering the kitchen, flooring, and trim, shows how much one level can change. If your ground floor sees water now and then, our guide to flooring for flood-prone homes on LBI is worth a read before you pick materials.
You Love Where It Sits
You can’t rebuild a location. If the lot, the view, or the short walk to the beach is why you bought the place, investing in the house you already have often makes sense.
The Flood Math Works
If your scope stays comfortably under the substantial improvement threshold, or the house is already elevated, a renovation keeps things simple. That’s usually the sweet spot. Your money goes into the rooms you’ll actually use.
When It Makes Sense to Think Bigger
A renovation starts losing its appeal when:
The first floor sits low and takes on water in big storms.
Your plans would push well past the 50% threshold, so you’d be meeting current flood standards regardless.
The roof, wiring, plumbing, and HVAC are all near the end of their life at the same time.
You need more space than the current footprint can give you.
Hidden damage keeps turning up every time a wall opens.
None of these is an automatic dealbreaker. But two or three together usually point toward a new build, and it’s better to know that before demo day than after.
Hidden Costs That Come With Older Shore Houses
Older homes have quirks, and a good estimate plans for them.
Lead Paint in Pre-1978 Homes
If your house was built before 1978, it may have lead-based paint somewhere under the newer coats. The EPA’s Renovation, Repair and Painting rule requires anyone paid to disturb painted surfaces in those homes to be certified in lead-safe work practices. So ask any contractor how they’ll handle demolition.
Code Requirements for Existing Buildings
New Jersey handles renovation work through its Rehabilitation Subcode, a stand-alone set of rules the state describes as common sense requirements for restoring and reusing existing buildings. It’s separate from the rules for brand-new construction, but floodplain requirements are their own track, so the 50% question still applies.
Salt Air on the Exterior
Roofs, siding, decks, and windows take a beating on the island. If you’re opening up the inside, have the exterior inspected too, since a beautiful new kitchen won’t help much under a tired roof. Our roofing work on Long Beach Island and siding replacement can be folded into the same project so you’re not hiring a second crew next spring.
Phase It or Do It All at Once?
Phasing spreads out the cost. That’s the upside. But it also means living through construction more than once, and in towns that track improvements cumulatively, it may not keep you under the 50% line anyway. For most families, one well-planned project during the off season is less disruptive.
Timing matters on LBI. Everyone wants work done between fall and spring so the house is ready to enjoy or rent by summer, which means builder calendars fill up early. Hoping to be back in by Memorial Day?

How We Approach Older Homes at Nardini Custom
Every home renovation on LBI we take on starts with pre-construction planning: design proposals, construction documents, a master schedule, detailed estimates, and permit acquisition. You see the full picture before anything gets torn out. Afterward, we handle the certificate of occupancy paperwork, the punch list, a custom homeowner manual, and a warranty walkthrough 11 months later.
Our Ship Bottom showroom lets you pick cabinetry, flooring, countertops, and finishes in one place with design help, including brands like Plain & Fancy, Cambria, and Duchateau. Build clients also get wholesale pricing on selections, which adds up fast on a whole-house project.
If part of the job is recovering from a storm, our flood and storm damage repair can be built into the larger plan, and our article on renovating an LBI home after storm damage walks through the order of work.

Frequently Asked Questions
Is it worth renovating an older house on Long Beach Island?
Often, yes, if the foundation and framing are sound and your project stays under the substantial improvement threshold. If the work would exceed 50% of the structure’s market value, a new elevated home may be the better investment.
What is the 50% rule for renovations in a flood zone?
Under the NFIP, work that costs 50% or more of a building’s pre-improvement market value is considered a substantial improvement. The home then generally has to meet current floodplain requirements. That can include elevating it.
Does the 50% rule include the value of the land?
No, it’s based on the structure’s market value before work begins. Your local floodplain or construction official makes that determination.
Can I split a renovation into phases to avoid the 50% rule?
Not always. Some LBI towns track improvements over time. Surf City, for example, reviews permits from the previous ten years.
Should I renovate or tear down my shore house?
It depends on the structure’s condition, how low the house sits, your budget, and your long-term plans. A builder who does both renovations and new construction can give you a balanced comparison.
When is the best time to start a renovation on LBI?
Most owners aim for fall through spring so the house is ready by summer, and since calendars fill quickly, it’s smart to start planning several months ahead.
